Test feature allows local businesses to promote specific content, which can be shared directly from the “card carousel.”
Google is experimenting with new “Business Cards” in search results, as part of the Google Posts system. Both Business Cards and Google Posts are our terms, not Google’s, which has declined to name them. But they are a reasonable description of a new card carousel test that features content from local businesses near the top of search results.
This was first spotted by Mike Blumenthal, but I have confirmed with Google that this is a real test. Business Cards are built on the same display functionality as Candidate Cards, launched a few weeks ago.
