\
Apart from utilizing tools, you can also implement some important tips to improve the user experience of your website. They are as follows

## Tips to Improve Core Web Vitals

Here are 6 tips that improve your website Core Web Vitals scores. Let’s know them:

\

1. **Reduce JavaScript (JS) Execution**

\
If you notice a poor FID score on the report, it means the page takes more than 300 milliseconds to interact with users.

\
Reducing the time between your browser execution JS code and page which in short is also called JS execution.

\
Also, make sure to use as little memory as possible because whenever your site’s code requests the browser, it occupies memory that stops JavaScript and possibly slows down the page.

\

2. **Pay attention to attributes or dimensions of your media or ads**

\
This is very important to improve your CLS scores. One must ensure that their image or any media source’s height or width is proper.

\
If you plan to place any display ad make sure to set your ads with proper dimensions because improper ads can reduce the CLS score.

\
Thus, keep an eye on other media sources as well if you wish to place any.

\

3. **Image Optimization**

\
Images are one of the most influencing factors in web core vitals.

\
With the plenty of lazy load packages out there you can use one to lazy load all the images on your page.

\
This will make your page lighter and require less loading time for rendering your page in the browser.

\
One more important thing, define your image resolution based on the device type. The resolution for different devices should be different.

\

4. **Improve the server response time**

\
A long-serving response time is harmful to your SEO and negatively affects your UX.

\
You can use specialized tools to measure the server response time. However, before starting, compile the data of your current performances to identify how you are doing.

\
To compile the data:

* Check the speed of web hosting
* Use (Content delivery Network) CDN.
* Pick only necessary plugins for your site as each comes with an additional weight that can affect your site’s performance.

  \

Based on the report, work on your site’s improvements and make your response server time faster. A faster server time improves page load metrics and LCP as well.

\

5. **Reduce the overall page/document size**

\
A heavy landing page contributes badly to the LCP score. To avoid this only use the data that is necessary for your rendering page and eliminate all the useless data.

\

6. **Use fonts wisely**

\
Fonts can drop your performance scores if the browser takes time to load the custom font used on your site.

\
The good thing to do here is to load your site with the fonts that are by default supported by the browser.

\
These tips will enhance the page experience for your users and have positive effects in both the long-term and short term.

## Final Words

Improving page experience as a part of your SEO strategy can improve the user experience of your site and possibly improve the ranking of your site.

\
Google supports the site that delivers valuable and comprehensive content along with a good user experience. So make sure not to miss on creating good content for your readers along with delivering a good user experience.
