What sits under each factor?
- Relevance. Your primary category, additional categories, services, description and the content of your website. Google states that complete, accurate information helps it match searches.
- Distance. The location of your pin compared with the searcher. You cannot change this without moving.
- Prominence. Reviews and ratings, mentions across the web, directory listings and links. Many practitioners find links and consistent citations support this part, though Google has not given a recipe.
Notice that the second item is the one nobody can edit, and it is the one with the most visible effect on a single search.
