Google & Bing delete billions of AI spam pages
November 28, 2025
While the world hunts for discounts, one of the most radical changes of the last decade is taking place in the engine room of the internet. In an unannounced but apparently coordinated action, Google and Microsoft (Bing) began today to massively clean up their search indexes. Experts are already talking about the “SEO Apocalypse 2025.”
The End of the “Dead Internet”: The Background
Since the release of powerful text generators (such as GPT-5 and Gemini Ultra) in 2024, the World Wide Web has been subjected to an unprecedented flood. So-called “content farms” use automated agents to generate millions of articles daily, all serving one purpose: to generate advertising revenue through clicks.
The Problem: These texts are often flawlessly written, but devoid of content. They repeat well-known facts, inflate 50 words of information into 2,000 words of text, and clog up search results for legitimate queries.
“We reached a point where, for some search queries, not a single human-verified sentence could be found on the first three pages of results. The internet was threatening to choke on its own noise.” – Dr. Elena Rostova, Chief Analyst for Search Quality at Forrester Research.
The weapon: “Semantic Density Filters”
The extent: A digital devastation
Initial data from SEO tracking tools reveal the massive scale of the event:
Visibility Crash: Large networks of niche websites (e.g., “https://www.google.com/search?q=Bester-Toaster-Test24.com” or generic health blogs) lost 95% to 100% of their visibility within four hours.
Billions of Deleted URLs: Search Engine Land estimates that by evening, approximately 15 to 20 billion unique URLs worldwide will disappear from indexes. This equates to roughly 10-15% of the indexable web.
Traffic Shift: Established media brands, forums (such as Reddit), and verified expert blogs are experiencing an immediate surge in traffic as the “spam competition” disappears.
Collateral damage and criticism
As with any major algorithm update, there are innocent victims here, too. Webmaster forums are already seeing reports from operators of small hobby blogs who have also been removed from the index.
Critics argue that the “Semantic Density Filters” are set too aggressively and penalize even flowery or verbose human writing styles as “AI rambling.” Google has already announced that it will provide a form for manual reviews in the coming days, but for many small businesses, this could come too late!
A Return to Quality?
November 28, 2025, marks a turning point. Flooding the internet with generated content for “free” is no longer a viable business model. Search engines have signaled: Those who want reach must once again provide genuine, concise, and relevant information—regardless of whether it’s written by humans or machines.
