Let me tell you what just happened to a LOT of websites last month. Good sites. Sites with real content written by real humans. Sites that were doing everything "right." They woke up in February and their visibility had fallen off a cliff. No warning. No manual penalty. No obvious reason. Turns out the problem was not their content. It was not AI. It was not even a "quality" issue. It was their Table of Contents. Yeah. That helpful little jump menu at the top of blog posts and service pages. Google started treating every single one of those #anchor links as a separate page. So your one great page suddenly looked like a dozen duplicate pages to Google. And instead of just ignoring the extras — it punished the whole site. Here is what to do RIGHT NOW if you have long-form pages with a TOC: Stop the bleeding: Remove the clickable jump links from your Table of Contents. Just delete the linked list at the top. Keep your headings exactly where they are — those are still helping you. The clickable links are causing the problem. Check the damage: Go into Search Console. Performance. Filter pages containing the # symbol. If you see a bunch of impressions on those URLs with almost zero clicks — that is your smoking gun. Going forward: If you want a TOC for your readers, it needs to be built with JavaScript so Google cannot see the links. More on this soon. Your H2 and H3 headings are still doing great work for you. AI models love them. Google needs them for context. Just stop giving the crawler extra URLs to choke on. Simple fix. Big impact. Do me a favor — go check your Search Console right now and drop a comment letting us know what you found. Even if it is clean, that is worth knowing too. And if you have already seen weird ranking drops in February and could not figure out why — this might be your answer. Hit reply and tell me what you are seeing.
