There are no shortcuts to Local SEO. You can't try to game the system with Google as it doesn't work, their algorithms are too advanced and smart. Ranking a Google Business Profile in Maps requires good foundational on-page optimization, local signal creation, brand prominence, good content and lots of reviews on Google and third party review sites. It's also a good idea to reverse engineer the top ranking competitors in your market & niche to understand why Google is preferring them. To beat them, you'll first need to achieve competitor parity with the top-ranking sites/GBP listings for your target terms in your market.
