For almost 30 years 15 of my top 20 pges have been specific widget product pages however so far this month only ONE specific page is there and at #20!
I am seeing the same thing. Two months ago Google demoted one of the most popular and important pages on my site for the last 20 years, and one with the most links. It went from #3 to #11-#14. Since then it has stayed in the lower range. In the meantime, new sites appeared that are shifting around at the top, along with a lot of really stupid junk like people's individual instagram accounts! From what I see, once again Google has demoted sites with interior (landing) pages about multiple topics...in other words, the section of my site about that specific topic just can't compete with the home pages of other sites that are bout that one topic. This may revert again...I have seen it flip flop more than once over the years.
Today I read the AI overview for the topic in quiestion, which is enormous...it takes the top third of the page.
My own name and website were mentioned THREE TIMES in the AI Overview. Once in the opening paragraph without any link (three of the five people mentioned were linked to their website, two were not). Mentioned again in a list below the paragraph...this time my name was not linked but the small link icon was next to my name. The same sites that had their names linked in the opening paragraph also had their names linked in the list. Finally, my site was listed in the block of sites with images at right, in spot number one...and that is clickable.
So, to make it short...I was mentioned three times in the AI Overview for a search where I used to rank #3 and yet my traffic to that page has dropped so low that it is now the 14th most visited page on my site, below many less important pages. Losing the Google search traffic has completely removed any business for that search for two months now. So I really don't see how AI Overviews will help to drive any real business to a site, even if you are mentioned prominently.
I am wondering...is there any relationship between the sites that are linked in the AI Overview and their adwords spend? Has this been established yet?
