Google announced the Google December 2025 core update on Thursday afternoon, December 11th, and it already has a significant impact on Google Search results. The most noticeable day of the impact was Saturday, December 13th, but there are plenty of signs it started to hit hard on Friday, December 12th.
Here is a recap of what happened in the search forums today, through the eyes of the Search Engine Roundtable and other search forums on the web...
Nick Fox is the SVP of Knowledge and Information at Google was interviewed again on the AI Inside channel by Jason Howel and Jeff Jarvin. He said a lot of interesting things but said no, Google won't be offering standarized licensing deals for all publishers. He also said that optimizing for AI Search is the same as what you do for web search and normal SEO.
Google updated its JavaScript SEO documentation to warn against using a noindex tag in the original page code on JavaScript pages. Google wrote, "if you do want the page indexed, don't use a noindex tag in the original page code."
Google can not show ads in AI Overviews with the exact match type. This is a change from back in May, where Google said otherwise. Ginny Marvin, the Google Ads Liaison, wrote on X, "We have since updated this."
Earlier this month, we documented that the average position sharply increased for many sites when Google made that num 100 change blocking a lot of automated queries. Well, for some sites, that number is dropping again, which may mean that there is a workaround for the blocking of those bots and automated queries.
