Does Instagram work for local search, or only Google?

No, not for someone who types the trade and the area: that search is on Google. Instagram is for someone who already follows you or scrolls past nearby, not for “dentist in the town” or “menu near me”. Run the search on Google and look at the profile. If the phrase exists there, the search money goes to Google, because Instagram does not appear in that result. Google is switched off because the feed has likes, and nobody covers the search. The place opposite shows on the phone of someone who wants to book today. Google for the search, with the listing and a text ad or a real photo. Instagram, if it comes in, is the same cap at another time, not the replacement.
