Google is sometimes showing a hyperlink at the bottom of its search results named “About this data.” This links to a Google help document in Merchant Center support named “How Google sources and uses information in the brand profile.”
This was spotted by Sachin Patel who posted a screenshot of this on X – I was able to replicate this as well:
Again, when you click on it, it takes you to this Google help document.
My guess, this is a misplaced link that should be tied directly to some merchant information within the search results screen and not placed at the bottom of the page.
Forum discussion at X.
