Of course there are countless more places where you could possibly list your business, but each come with differing variables. Some don’t have anything to do with your niche, have very low user count, have low search queries for your industry, have a recurring cost associated with being listed, don’t provide an area to fully complete company information, etc.
We find that Facebook, Google, Yelp!, and Bing are platforms that serve clients the best. They have large audiences, good amount of search queries, don’t start off with recurring costs, have abilities to scale into advertising, and ultimately give you the best chance to be seen by your ideal customer.
