Google Spam Update Causes Weekend Volatility and Ranking Changes

The Google September 2026 Spam Update has had a significant impact since its rollout began on Friday, September 25th. The update's effects were particularly pronounced over the weekend, with volatility calming down slightly on Monday, September 28th.

According to various tools tracking search engine rankings and volatility, the update appears to be targeting multiple tactics, not just one specific approach. Glenn Gabe shared some early data on Friday, but he has yet to release more charts, which will likely provide further insight into the update's impact.

The 'Spam Update Notes' reveal interesting findings about AI-generated sites, such as Grokipedia, which experienced a significant drop in traffic during the mid-September volatility. The exact targets of this update remain unclear, but it is evident that Google is taking steps to combat spam.
