For any brick-and-mortar business, the Google Maps listing is doing more conversion work than the website. A searcher types "plumber near me," Maps returns three results, they scan star ratings, they tap call. The whole transaction fits inside the map pack; your website never loads.
The Google Maps Listing Audit scores the eight signals that decide whether your pin gets tapped. Rating at 4.2 or above. Twenty or more reviews (volume matters, but recency matters more). Phone visible. Address populated. Hero photo. Hours accurate. Category matches what people search for. Description substantive.
Below 4.2 is brutal. A rounding error in aggregate ratings drops map-pack inclusion noticeably. If you're at 4.1 because of one two-star review from 2023, targeting five fresh 5-star reviews this month usually pulls you back up. That's the kind of lever the generated AI prompt walks you through.
This is the lite version of the full GBP Competitor Audit; run this first on your own listing, then that one against competitors once your baseline is solid.
