A sharp drop in website traffic is a serious signal that something is wrong. If it happened without any changes on your end, it’s time for a deep dive. One of the first things I always recommend checking? Outbound links. While working on my project, Gone.Domains, which helps find expired domains from high-traffic websites, I came across an interesting case. To test a new feature, I crawled a site with 185,000 monthly visitors that focused on digital topics. During my analysis, I spotted something alarming — many of the domains I found had a high domain rating but contained words related to the adult industry. This was odd, given the website’s niche. What happened? The site had been hacked by a bot. The bot automatically created user profiles and allowed websites to be added to the profile information. This led to hundreds of outgoing links to adult websites, all coming from a trusted resource. The result? Some shady sites got strong backlinks, and the hacked site unknowingly linked to hundreds of suspicious domains. Google’s algorithm isn’t kind to this kind of activity. Search engine penalties The website owner probably had no idea what was happening. But when search rankings started to drop, so did their business. Here’s what likely happened: Google’s spam detection system flagged the suspicious outbound links. The website lost its authority and ranking in search results. Organic traffic took a major hit, impacting revenue and visibility. If you ever see a sudden drop in rankings, don’t just assume it’s an algorithm update. Check your outbound links. How to protect website Regularly audit outbound links — Use Google Search Console to find and analyze links leaving your site. Remove suspicious links — If you find any shady or spammy links, remove them immediately. Check for unauthorized user-generated content — Hackers often inject links via comments, profiles, or forums. Monitor website security — Keep your CMS and plugins updated, use strong passwords, and enable security monitoring. Disavow harmful links — If your site has already been impacted, submit a disavow file in Google Search Console to remove harmful associations. Never associate your website with hacked, pornographic, or malware-ridden domains. Even if it happens unknowingly, Google’s algorithm doesn’t care — it will penalize you anyway. If your website’s traffic suddenly drops, start with the basics. Check your outbound links first. You might just save your site before it’s too late.
