It’s tough to say how long it takes to build local SEO authority, but we can tell you that it’s a pretty lengthy process. First you have to get your business listed on Google My Business so they’ll start getting indexed by the search engine. You also need to populate your GMB information with NAP info and a great description of what your business does. Next, you’ll need to build links from local news sites, get reviews for your business on your Google Business Profile, Facebook, and Yelp. That’s the quick version of the process, too. It takes around 6 months or longer before you’ll see results in terms of rankings in local search results.
