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...
Google Discover is testing and maybe rolling out an option to "Tailor your feed." This allows you to tailor the feed with "Say in your own words what you want to see," and Google will try to figure it out.
If you submitted a review appeal within Google Business Profiles it will likely take longer than normal to hear back. Google's review appeals are delayed and Google cannot provide a specific response timeframe for pending cases.
Google is testing extremely long and expandable search result snippet descriptions in the search results. These are also AI-generated snippets, which we've seen before, but not this long. This goes on for eight lines of text.
Google has updated its Manage customer reviews help documentation to expand and clarify the "Understand what happens to your replies" section. It now specifies why a business reply to a review may be hold, how long it takes and more.
