Still can't rank higher on google maps - what am i missing?

What's your primary category set to, and is your address actually inside the area you're trying to rank in? Those two decide most of it. Maps is proximity to the searcher first, then relevance and reviews. After that: fill in every field on the profile, pick the most specific primary category rather than the broad one, get reviews steadily instead of in bursts and reply to them, add photos, and make sure the name, address and phone match exactly what's on your website. If a competitor has 300 reviews and you have 12, that's the gap.
