Google's local ranking algorithm weighs three broad factors: relevance, distance, and prominence. A single mistake rarely tanks a listing on its own. The problem is that Google Places errors compound. A wrong category reduces relevance. Inconsistent NAP data reduces prominence signals. No recent photos or posts reduces perceived activity. Together, those three issues can move a listing from position two to position eight — or out of the Map Pack entirely.
The other compounding factor is time. Many businesses make these errors at setup and don't revisit them. Meanwhile, competitors who actively manage their listings accumulate reviews, add photos monthly, and keep their information current. The gap widens gradually, then suddenly.
This page walks through 12 specific errors in order of impact — starting with the ones that cause the most damage and working toward the subtle signals most businesses overlook entirely. If you're auditing your own listing, treat this as a diagnostic checklist. If you're trying to understand why a ranking dropped, start at mistake one and work forward.
One important note: Google Places is part of Google Business Profile (the platform's current name), and the two terms refer to the same system. We use both here because many searches still use the older terminology.
