Google now documents how a site can link to a claimed Search profile using an official badge or a text link. A Search profile gathers web and social content; it is distinct from a Business Profile listing. Source officielle.
A practical check
Confirm that the claimed profile exists, its URL points to the right organization, and the button does not distract from the main contact action. Follow the asset and touch-target guidelines.
A profile link may fit an article byline but be less useful on a booking page. Google's documentation also provides a plain text option, which may be clearer than another icon in a crowded navigation.
What the evidence supports
Measure clicks to the profile. Do not present the badge as a guaranteed ranking factor or a substitute for accurate local information. Date the check and retain the source documentation so that later changes can be verified.
