Google Maps rankings come down to three factors Google has been fairly open about: relevance (does your profile actually match the search), distance (how close you are to the searcher), and prominence (how well-known and well-reviewed your business is generally).
We can't do anything about distance — that's determined by where the searcher physically is. But relevance and prominence are both areas we can genuinely improve: accurate categories, a complete and well-optimized profile, consistent citations, and a real review-generation approach.
We won't promise a specific ranking position — nobody honestly can. What we focus on is making sure every factor within your control is actually working in your favor.
