A historical mistake and how you can solve it TL;DR: Most languages fail to find the correct behavior for leap year calculation. Disclaimer: While I've tried my best to provide accurate insights across various programming languages, I acknowledge that I may not be an expert in everyone. If you spot an error or disagree with any points, please leave a respectful comment, and I'll promptly address it. The State of the Art Determining whether a year is a leap (or not) is a simple mathematical problem. Every student can solve it as their first programming assignment. To simplify the problem, let's assume a Year is when it is evenly divisible by 4, except if it's also divisible by 100, but it is a leap year if it's divisible by 400. leap The real world and cosmic mechanics are a bit more complicated, but that is beyond the scope of this article. Let's explore how several programming languages solve this problem: Horrible Approach PHP: <?php

$yearNumber = 2024;
$isLeap = date('L', mktime(0, 0, 0, 1, 1, $yearNumber)); SQL (PostgreSQL): SELECT (EXTRACT(year FROM TIMESTAMP '2024-02-29') IS NOT NULL)
 AS is_leap_year; These languages attempt to create a valid (or invalid) leap day and exploit . truthy values This hack violates the fail-fast principle and abuses the . billion-dollar mistake Trying to create an invalid date should throw an exception in serious languages since this happens in the . real world domain Performing other actions, like concealing errors beneath the surface, breaches the principle of least astonishment. Missing Behavior Ada: function Is_Leap_Year (Year : Integer) return Boolean is
begin
    return (Year mod 4 = 0 and then Year mod 100 /= 0) 
        or else (Year mod 400 = 0);
end Is_Leap_Year; C/C++: bool isLeapYear(int year) {
    return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
} Go: package main

import (
  "fmt"
  "time"
)

func isLeapYear(year int) bool {
  return year%4 == 0 && (year%100 != 0 || year%400 == 0)
} Haskell: import Data.Time.Calendar (isLeapYear)
let year = 2024
let isLeap = isLeapYear year JavaScript/TypeScript: function isLeapYear(year) {
    return (year % 4 === 0 && year % 100 !== 0) || (year % 400 === 0);
} Julia: using Dates
year = 2024
isleap(year) Lua: local year = 2024
local isLeap = (year % 4 == 0 and year % 100 ~= 0) or (year % 400 == 0) MATLAB: year = 2024;
isLeap = mod(year, 4) == 0 && (mod(year, 100) ~= 0 || mod(year, 400) == 0); Objective-C: int yearNumber = 2024;
BOOL isLeap = (yearNumber % 4 == 0 && yearNumber % 100 != 0) 
  || (yearNumber % 400 == 0); PowerShell: $yearNumber = 2024
$isLeap = ($yearNumber % 4 -eq 0 -and $yearNumber % 100 -ne 0) 
  -or ($yearNumber % 400 -eq 0) Rust: fn is_leap_year(year: i32) -> bool {
    (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)
} Smalltalk: | yearNumber |
yearNumber := 2024.
(yearNumber \\ 4 = 0)
  and: [(yearNumber \\ 100 ~= 0) or: [ yearNumber \\ 400 = 0 ]] The above languages do not provide native support. You need to define global functions or use . helpers Incorrect Global Approach PHP (Again): <?php

$yearNumber = 2024;
$isLeap = checkdate(2, 29, $yearNumber); R: leap_year(2024) Ruby: year = 2024
is_leap = Date.leap?(year) Swift: let yearNumber = 2024
let isLeap = Calendar.current.isDateInLeapYear(
  Date(timeIntervalSince1970: TimeInterval(yearNumber))) These languages use to check if a year is a leap. global functions These global methods mistakenly place responsibility in the wrong location (a global access point). utility Helpers Bad Approach C#: int yearNumber = 2024;
bool isLeap = System.DateTime.IsLeapYear(yearNumber); Dart: import 'package:intl/intl.dart';
var year = 2024;
var isLeap = DateTime(year).isLeapYear; Perl: use Time::Piece;
my $yearNumber = 2024;
my $isLeap = Time::Piece
  ->strptime("$yearNumber-01-01", "%Y-%m-%d")->leapyear; Python: import calendar
leap = calendar.isleap(2024) Visual Basic .NET: Dim year As Integer = 2024
Dim isLeap As Boolean = DateTime.IsLeapYear(year) These languages use as libraries to check if a year is a leap. helpers The is not present in a real object but in a bag of . misplaced responsibly DateTime related functions The Year Approach Java: int yearNumber = 2024;
boolean isLeap = java.time.Year.of(yearNumber).isLeap(); Kotlin: val yearNumber = 2024
val isLeap = java.time.Year.of(yearNumber).isLeap Scala: val year = 2024
val isLeap = java.time.Year.of(year).isLeap These languages rely on the to check if it is a leap. Year The protocol is closer to the real world in the bijection Notice they create objects and not objects since this would also break the . Year Integer bijection A has a different protocol than an integer, and modeling a Year as an integer would also be a smell and a symptom of mixing . Year premature optimization the what and the how A can tell if it is a leap (an integer shouldn't do it) and can tell you about its months (which are , not integers, 1-based integers, or strings). Year Months 0-based Conversely, an 's capabilities extend to arithmetic operations such as multiplication and exponentiation. Integer Time is not a joke Representing a point in time as a , , or any other data type comes with consequences. float integer You can break a point in time in the real world in tiny fractions (but not ) too small Using is not a valid option. floats is not 0.03, and this has terrible consequences points in time. 0.01 + 0.02 dealing with floating point The Challenge We've been talking about leap years. What are the needs to know if a year is a leap? The date and time mechanics you model need to know the February 28th, 2024 successor. But this is your problem. NOT Following the information hiding principle, you should leave the responsibility as a private protocol. Conclusion There is no . Silver Bullet Use your language wisely. Today is February 29th, a leap day to pause and reflect on the tools you use daily. See you in 4 years.

When it comes to developing applications from scratch or working on an existing one, the process is not as structured as it may seem in tutorials or how-to guides. One runs into various errors and roadblocks that might take days to overcome. The issues can be anything from picking the right shade for the aesthetic to making sure the correct API calls are made where necessary. To ensure that this process can be as eased as possible, tools are built keeping in mind these problems and these tools can be easy to use and set up in the form of browser extensions which eradicate the obstacle of installation steps and just let you get your job done. Here are 10 Chrome extensions that a developer must try! 1. Requestly Requestly is a testing & debugging tool for frontend developers & QAs. Using Requestly, developers can simulate different API responses, debug JS in production, etc. QAs & Customer Support use Requestly to report bugs with video, console logs & network logs to make it efficient for developers to debug issues. Requestly is available across all major browsers and supports debugging on Android & IOS too. One of the top-rated extensions on Chrome Store. 2. Web developer This extension is a toolbox for developers. It provides you the ability to disable JS, play around with Cookies, highlight various CSS properties on your page, enable auto-completion in forms, emphasize certain parts of the web page to overcome any issue, and more. It is equipped to assist you in making your page responsive. Available for Chrome, Firefox, and Opera. 3. Wappalyzer Wappalyzer is built to help you find the underlying technologies of web pages. If there is a landing page you adore, just head to that page and you can check what kind of JS, or CSS framework is used to build it. In addition to it, it also displays the analytics tracker being used, issue trackers, the Platform being used for the page, and more. It can be used for competitor research, lead generation, and such. Available for Chrome, Firefox, Edge, Safari, and significant CRMs. 4. BrowserStack This extension has become the go-to dev tool when it comes to cross-browser testing. It allows you to test your web and mobile apps in various browsers simply from their application. Moreover, for mobile applications, it employs its data centers to provide a real device for testing rather than an emulator. It also has a separate extension for testing on Internet Explorer. Available for all browsers. 5. Amino: CSS Editor Amino lets you edit the CSS of your page just like you would in any editor. It is different from editing in the DevTools tab because they save your stylesheet and is applied every time the page is opened. One can also style pages by their domains or specific URLs. Available for Chrome. 6. Ghostery This extension is built to make surfing on the internet as private as possible. It enables you to decide if any site should have access to your personal data, provides anti-tracking and removes your data points, smart browsing to stop trackers from affecting website performance, and more. Available for Chrome, Firefox, Edge, Safari, and Opera. 7. Check my links Check my links is a browser extension used to verify if all the links present on your web page work fine. As seen in the image, it classifies links and highlights them according to their category on the page as well to make it easier for the developer to identify the broken ones. Available for Chrome. 8. React Developer Tools React Developer tools are built to assist one with debugging a React application. When the extension is installed and a site is using React, the extension is highlighted and you can find the ‘Components’ and ‘Profiler’ tabs in the developer tools. The Components tab shows the tree structure of the application and the Profiler tab lets you record performance. Available for Chrome, Firefox, and Edge. 9. Checkbot This extension is made for SEO, Security, and Speed testing of your website. It helps recognize broken links and duplicate content, helps with secure password forms, minifies CSS and JS for better speed, avoids render blocking scripts, and gives the report as shown in the image. Available for Chrome. 10. Octotree This extension allows you to have an overview of the file structure of a GitHub repository in a small side panel which saves time and helps in getting the job done more effectively. It also provides the ability to review Pull Requests, search through the repo, bookmark, and more. Available for Chrome, Firefox, Opera, Edge, and Safari. These are just 10 among hundreds of other extensions that exist to solve these problems and many more. I hope you’ll try at least one from this list and it makes your work a tiny bit faster and more efficient.

HackerNoon has reviewed the story for quality, but the claims hereon belong to the author. #DYOR It’s easy to forget how, not too long ago, web3 tooling felt like a time-intensive, debug-crazy endeavor. As the community grows, to solve the problems devs face when developing on blockchain. One such problem is the by smart contracts. new solutions arise lack of auto-execute methods calls The awareness of automation has been increasing since 2015, with the first attempt being the Ethereum Alarm Clock project. However, it was the that made clear the to simplify the adoption of . Defi explosion imperative need smart-contract automation A more in-depth explanation of the smart-contract automation genesis can be found at blog by David Liebowitz. David presents the three main solutions: The DeFi Future is Automated Gelato Ops by Network (production ready in July 2020) Gelato Network (since October 2020) Keep3r by Chainlink (open beta June 2021) Keepers We are going to analyze these solutions and include the one provided by Open Zeppelin: & Relayers, Defender by Open Zeppelin Autotasks : Although this analysis was commissioned by Gelato, all research was conducted independently and the conclusions are my own. Disclaimer Setting the scene When you participate in a hackathon and you want to integrate a protocol/solution to your project, you require four things docs are your best friend- this includes everything from good online documentation to tutorials, and even covers responsiveness in Discord channels or other forums when you have technical questions or are simply looking for guidance. 1) Resources: for this experience to be optimal there are a few things to consider, such as: 2) Build & Test- Whether you can create the task easily or if you have to first use additional resources that aren’t relevant to your task If you can find helpful templates or code snippets Whether the payment information is clearly displayed and easy to understand. If the solutions are deployed on different testnet If specific tokens are required, are faucets available? Can you test the full use case in a forked hardhat node or simply deploy it to testnet? - the main question to consider here is not only whether the solution is providing the (sometimes devs think that is finished when it is coded), but also other aspects that may influence : 3) Features automation you need for your project scalability and user adoption when moving to production Are there fees to be paid? If so, how much? Can the user pay with different tokens, and are alternative options for paying? Does the solution prevent ‘front running out of the box? Does the solution notify users when funds are running low? One crucial aspect of the features is the solution’s ability to provide the Though this isn’t relevant for the job itself, it can impact scalability when moving to production (after all, decentralization is sacred in web3) executors/keepers in a decentralized manner. : 4) Dashboard & UI Is there a dashboard where you can track the logs of executions How can you track tasks/jobs created by a smart contract? Showcase Projects We are going to test the solutions mentioned above in two different use cases: Increase counter, a classic hello world smart contract automation example, increasing a counter when a specific time has elapsed (or condition is met). a) Maintenance Task Examples: One shot and cancel, dynamically create and cancel the task. As the ecosystem grows, I imagine we’ll see an explosion of different use cases where we’re required to control our tasks programmatically. We will implement this use case only in Gelato and Chainlink Upkeep. b) On the Fly: The GitHub repo can be found . here Gelato Network How it works First, users complete through the The UI is pretty intuitive and asks for the contract address and the function you want to automate, in case the contract is not verified, you will have to provide the abi. registration . Gelato Ops UI We have three choices of triggers, time elapsed (run every n-time), whenever possible, and through a custom logic condition within a resolver contract (it can be the same as the execution contract). Gelato offers the ability to (if needed) . This is done , which comes in handy for automating tasks of already deployed contracts with custom logic. split the execution logic from the condition logic by creating a resolver contract Findings Very clear and to-the-point documentation is available. However, more “target to learn” resources with specific features will speed up the development process. There are testnets available, and development on a hardhat forked network is very easy, you just have to impersonate Gelato’s contract address. One very powerful Gelato feature is , which gives users the ability to create/cancel tasks within a smart contract. Gelato Network provides decentralized execution through a whitelisted set of Node Operators and plans to have achieved the ability to have, programmatically, full control over the tasks full permissionless decentralization by mid-2023 For the time being Gelato Network to the transaction cost. Gelato offers the possibility to deposit funds (like ChainLink or OZ Defender) but also doesn’t add any fee the ability to pay independently for each transaction. Gelato ensures privacy by submitting transactions through flashbots . It also provides users with a very for when users are running into low balance. enabling front-running protection simple interface to set up a Discord or Telegram notification bot Gelato provides an for registering and controlling the execution of the tasks. You can find jobs by the connected wallet or “on the fly tasks” by searching the input contract address. The UI also provides the to understand when a transaction reverts. intuitive UI dashboard transaction logging Showcase Contract Increase Counter: Contract verified on Mumbai Gelato Ops Ui with logs Showcase Contract Create and Cancel Task: Contract verified on Mumbai Gelato Ops Ui with logs The task has been created with the createTask() and was paused after one execution. Keep3r network How it works At a first glance, Keep3r appears to be similar to Chainlink UpKeep or Gelato. The first step is to, register your job in the , and then implement a specific interface in the contract defining the Keep3r Network UI conditions and providing the execution logic However, the similarities end here: The way to pay the keepers/executors is very different from other solutions, as users pay the keepers with the yield accrued in a pool where the user provides liquidity. In order for the keepers (Keep3r network provides decentralized execution) to pick up your job, users have to publish an npm package with specific scrips (there is a Keepers-Cli-Boilerplate that you have to fork and merge). Findings Although the developer experience is really tough, with almost no detailed docs/tutorials on how to implement a job, within the forum and discord, (user wei3erhase supported my tests). the Defi Wonderland Team provides excellent support This solution is focused on maintenance/pre-programmed tasks. (although feasible) I don’t believe that the implementation of this solution as the infrastructure of keep3r requires off-line manipulation. For very dynamic scenarios is fit for purpose Guided tutorials and “easy to find” test addresses would be beneficial. The key feature of the Keep3r network is the implementation of the payment option by the yield accrued into a pool. This allows users to and in the future. provide liquidity one time doesn’t require any funds Keep3r and encourages every user to join. Though it may appear complicated at first, in the frame of this post, I’ve been able to understand the structure and how it works, and have simulated a task execution with the CLI (I could join the network as a Keeper) is a pure decentralized network Keep3r ensures privacy by submitting transactions through flashbots . enabling front-running protection Keep3r Network with more documentation targeted to “no pro” developers. could increase user adoption by improving the Ux experience Increase Counter: Contract verified on goerli Npm Package with job Chainlink Keepers How it works First, users will need to an “Upkeep” (task/job) within the Chainlink Keepers Network in the , and then connect their wallet. register keepers UI We can define the time interval to trigger the Upkeep or specific custom logic with a condition, for this later case we are required to inherit the KeeperCompatible interface into our contract (it’s a very simple interface with two functions and the required addresses). Within the UI we will need the contract address and if it isn’t verified we will be prompted to input the method’s abi. In order to finish the registration, you can input your email for notifications. You will be notified when funds are low. Findings The Chainlink ecosystem is also very well documented and there are a lot of resources, tutorials, and posts. However, it would be helpful if there were more documentation and tutorials for “on the fly” tasks. Implementing recurrent automation is quite straightforward and easy to understand. The fees on mainnet amount to 20%. As in other applications within Chainlink, . More flexible payment methods would be beneficial. you will need LINK to operate Both testnets and faucets are available. If you want to develop locally with a forked network, although this feasible (you will have to deploy it locally using a Chainlink node), it can be cumbersome if you haven’t done it before. is Chainlink Keepers have started to provide the . So far the functionality only allows users to create a task within a smart contract with specific custom logic. If a use case requires a time interval or only one run of the job, users will have to code it within the condition or execution logic. As developments occur very quickly in web3, I will have to review this post in the coming weeks to update the available features. ability to control the tasks programmatically The way to set multiple Upkeeps to the same contract is by passing custom checkDataparam to the checkUpKeep(bytes checkData) and performData into performUpKeep(bytes performData), in very dynamic use cases this architecture doesn’t help devs like me to have cleaner code. On the other hand, this architecture allows and only passing within the performData the required data for the performUpKeep() execution. the offsetting of some gas-intensive calculations off-chain Gelato Network provides decentralized execution through a whitelisted set of Node Operators. Chainlink provides a for registering/controlling the execution of the tasks. very intuitive dashboard UI The dashboard shows the UpKeeps registered by the connected wallet. Moving forward it will help devs to implement a search functionality by contract address for “on the fly” created tasks. ChainLink summary Official feedback from Chainlink is still pending, therefore my comments and analysis may change in the future. Showcase contract increase Counter: Mumbai Contract verified on UpKeep UI & Logs Create and Cancel Task: Contract verified on Rinkeby UpKeep UI & Logs Open Zeppelin How it works Users need to a in charge of the execution and an . Within the autotask, define the under which the task has to be triggered (by time or webhook) and any custom logic needed to define the register relayer autotask conditions execution. The relayer and autotask registration (shown below) are done through the defender UI where you’ll need to create an account (web2 email/password), the autotask can also be created, updated, or deleted through a POST API call. Open Zeppelin Findings Starting to learn and build with the Open Zeppelin is very rewarding, as guidance is concise, easy to understand and very well documented. The proposed solution makes it very easy to create recurring tasks that are triggered every n- time. One very interesting feature proposed by Open Zeppelin is the ability to , which fits very nicely with the sentinel ability to be notified when events on-chain happen. trigger the autotask by a webhook Open Zeppelin does “out of the box” to create and cancel a task on the fly from a smart contract. The between two triggers , a smaller interval can be achieved by a never-ending loop. not allow minimum time is one minute The solution does not provide a decentralized execution.

An Overview of Smart Contract Automation Solutions

The HackerNoon Newsletter: How to Checkmate in SaaS with the Power of Free (10/24/2024)

There’s no such thing as a Free lunch. But what if there’s a thing called Free launch that gives you… A) better features than your major VC-funded competitors B) unlimited usage C) an impression that the founders must be out of their mind? And what if they use COMPETITORS BRANDING in their MARKETING… …and get a notice from a competitor’s legal team as a result? I don’t know about you but to most people his might seems like an risky-bold-orangutan move to start your SaaS with. Especially if the founders are playing with the own money and have 100% skin in the game. But let’s see why it’s actually brilliant & likely leads to a CHECKMATE: So there are several things going on here that I like: Founders mean real people, and they’re going against VC funded big boys.
FREE after FREE vs paying several hundred dollars per month
The reference to competitors as incumbents (anyone with a permanent vacancy in a market is likely to get too comfortable in time) So my limbic brain is now on overdrive with dopamine - I need to justify taking action with some logic: This is pretty much all the logic I need. But I’m a true skeptic so… …if I’m a user in one of these incumbents’ platforms - how do I know that this is the real deal? I need to check if others have successfully migrated to this platform. PLUS I don’t trust any reviews on company’s own testimonial sites if they’re not in video format. (Commslayer, this is your CTA. Faces are good, videos are better - combined in building social proof they do MAGIC for conversion rates) So I have to check 3rd party sites like shopify app store. (I get reminded where I’m coming from on their website btw) I click on that ‘Install on Shopify’ -button and here’s what I find: My conclusion is they’re still in the early stages in terms of customer adoption. So we might need a larger simple size to make a more detailed analysis. But we can also dive into the quality of the reviews. One of them, from ‘bldblz’ (US), reads as follows: ‘‘Was evaluating this vs Gorgias and the value and product offering this has is leaps and bounds better for a way better price. If you're looking for a customer support platform with all the essentials you need, look no further than Commslayer! If I could give this 100 stars I would!’’ 100 stars is 20X than what’s allowed, so this user must be pretty happy. Let’s check another one, this time from Patina (DEN): I was about to write "by far the best value for money support platform," but that seems silly when it's totally free.
So, instead, I'll just write that it's the best support platform of all the platforms we've used, and we've been through a few: both Gorgias (too expensive), Re:amaze (buggy UI), and DelightChat (also buggy UI). CommSlayer is my favorite — by far.
My current favorite feature is the Superhuman-like keyboard shortcuts that allows me to go through tickets blazingly fast Both of these are what I would call raving fans in marketing lingo. Maybe this is the real deal? One thing is for sure in SaaS: People can’t resist the Power of Free if your offer is GOOD. And it seems to be the case here: Now migrations are typically PITA (pain-in-the-ass). You don’t want to do one unless you absolutely have to. But it doesn’t come to me as a surprise by now that… smoothing this pain is covered on the migration page as well: This strategy is straight out of Alex Hormozi’s playbook with a nice SaaS twist: Give more value to the market than anyone else, for free.
Mock people who charge ridiculous amounts for products that you give away for free
Delay making money as long as you can while you keep giving value and serving your core market Prediction: Competition intensifies (but is it competition if some alternatives are Free???) A flood of Shopify merchants will migrate from incumbents. This is a CHECKMATE move with the Power of Free in SaaS Helpdesk niche. Well played! There’s no such thing as a Free lunch. But what if there’s a thing called Free launch that gives you… A) better features than your major VC-funded competitors B) unlimited usage C) an impression that the founders must be out of their mind?

Maybe this is the real deal? One thing is for sure in SaaS: People can’t resist the Power of Free if your offer is GOOD. Power of Free And it seems to be the case here: Now migrations are typically PITA (pain-in-the-ass). You don’t want to do one unless you absolutely have to. But it doesn’t come to me as a surprise by now that… smoothing this pain is covered on the migration page as well: This strategy is straight out of Alex Hormozi’s playbook with a nice SaaS twist: Give more value to the market than anyone else, for free. Mock people who charge ridiculous amounts for products that you give away for free Delay making money as long as you can while you keep giving value and serving your core market Give more value to the market than anyone else, for free. Mock people who charge ridiculous amounts for products that you give away for free Delay making money as long as you can while you keep giving value and serving your core market Prediction: Competition intensifies (but is it competition if some alternatives are Free???) A flood of Shopify merchants will migrate from incumbents. This is a CHECKMATE move with the Power of Free in SaaS Helpdesk niche. Well played!

Similar to HTML, you can set the attribute on checkbox inputs. It needs to be set to a Boolean value. If set to , the checkbox will be automatically selected. If the value is , or there’s no default at all, the checkbox will not be automatically selected. defaultChecked true false Let’s look at an example: <input type="checkbox" defaultChecked="true" /> This is a simple uncontrolled checkbox. The attribute is set to a Boolean value . In the real world, is often set to a Boolean value from the state, or a complex condition that evaluates to or . defaultChecked true defaultChecked true false Set the Default Value of a Controlled Checkbox in React In most cases, it’s best to create controlled inputs in React. These are inputs that get their value from the state. Changes to the checkbox also update the state. Let’s look at a of a controlled checkbox: live demo import "./styles.css";

In this case, we do not set the attribute on an input. attribute results in less code and works the same. value defaultChecked We can keep track of the current value of the checkbox and use it for conditional styling, rendering, and other dynamic features in React.

The shopping cart and order finalization process play a crucial role in any online store. If not properly optimized, these areas can become bottlenecks that lead to cart abandonment. Studies indicate that cart abandonment rates can reach as high as 60-70%, and even higher to around 85% [1]. There are many reasons why customers may leave a site store without ultimately making a purchase. From poor performance to bad design, errors on the site to confusing delivery costs, return policies, and deliveries. Creating online stores requires analyzing many elements, including shopping cart and order summary pages. To improve the customer experience, increase conversion rates, and maximize profits, it is essential to take specific steps and continuously monitor and optimize the online store. Remember: Collect feedback from customers regularly to identify potential issues and areas for improvement. Implement email reminders for abandoned shopping carts to win back customers and address any problems. Regularly check the functionality and performance of the online store. Ensure the online store's performance is fast and reliable. Provide Clear and Valuable Information Make sure that the rules and regulations of the online store are easily accessible and visible to customers. Consider including links to terms and conditions, return policies, and shipping rules in the top menu, footer, or alongside product information. Creating a dedicated Frequently Asked Questions ( ) section or subpage can also help address common customer queries and reduce repetitive inquiries. FAQ Remember: Create dedicated sub-pages for store rules, shipping rules, and return policies. Ensure easy access to information related to regulations, shipping rules, and returns (via links in the footer, menu, and product pages). Include a section or subpage with frequently asked questions (FAQ). Allow Easy and Quick Account Creation Creating a customer account on the online store can provide numerous benefits for both customers and store owners. However, it's crucial to simplify the account creation process to avoid discouraging potential customers. Consider allowing buyers to log in to existing accounts or create new accounts in a simple step on the order page. You can also explore the option of single sign-on (SSO) using external identity providers like or . Google Facebook Remember: Add the option for buyers to log in to existing accounts during the order process. Allow buyers to create accounts quickly and easily on the order page. Explore the possibility of implementing single sign-on (SSO). Streamline the account creation process as much as possible. Ensure Clear, Simple, and Transparent Order Finalization Order finalization should be straightforward and free from unnecessary elements that can lead to cart abandonment. Highlight the steps involved in completing the order and provide easy navigation options for customers to review and edit their information. Consider removing distracting elements like the footer and menu navigation during the finalization process. Simplify the order form by including only essential fields, eliminating duplicate information, and enabling autocomplete features. Adopting a minimalist approach and minimizing the steps required to complete the purchase can help reduce the risk of cart abandonment. Remember: Remove distracting elements from the order summary page (retain cross-selling in the shopping cart but remove it from the order summary, where it makes more sense to introduce up-sells). Include only the necessary fields in the order form. Enable autocomplete fields and provide prompts for address-related information. Provide Convenient and Secure Payment Methods Offering secure and convenient payment methods is crucial for order finalization. Ensure that your online store has an SSL certificate for secure transactions. Consider partnering with reputable payment providers relevant to your market, who offer various functionalities and integrate with popular electronic wallets like Google Pay and Apple Pay. For international payments and multiple currencies, explore options like Klarna, Stripe, or PayPal, which cater to foreign markets and support local payment methods. Remember: Provide proven and secure payment methods from reputable operators. Enable various payment methods, including payment cards, debit cards, bank transfers, and electronic wallets. Assure customers of payment security. Provide Fast, Affordable, and Convenient Shipping Methods Customers expect fast and convenient shipping, and although free shipping may not always be feasible, there are alternative strategies to consider. Set a threshold amount for free shipping on larger purchases, include shipping costs within product margins, or offer an express shipping option for customers who prioritize speedy delivery. Additionally, provide a wide range of delivery options, including courier services and pick-up points, to accommodate customer preferences. Remember: If possible, offer a free shipping option for orders above a certain amount. Provide an express shipping method for customers who require faster delivery. Offer a variety of delivery options, including pick-up points. Ensure Everything Works Regular maintenance and monitoring are crucial for the smooth operation of an online store. Update the store's software regularly, but remember to create backups before making any changes. Proactively check for unexpected errors and ensure that everything is working flawlessly. Continuously analyze data and make thoughtful improvements based on customer feedback and performance metrics. While there are no one-size-fits-all solutions for complex systems like online stores, starting with simple and quick implementation suggestions can yield positive results. Remember that continuous and thoughtful improvement, based on collected data, is the foundation for enhancing the online store's performance.
