A new Google experiment updates the search results snippets to show tags related to the page. But these tags don’t seem to do much of anything.
Google has confirmed to Search Engine Land that they are experimenting with a new feature in the search results. I happened to stumble upon a search results snippet in Google that showed “tags” within the snippet. The unusual part of this was that the “tags” didn’t offer any additional functionality.
Google would list “tags” relevant to the page content in the actual search results listing snippets. You were not able to filter by those tags, click on them or anything. It just listed “tags” in the snippets without showing you anything more.
