A local business listing is an online portfolio containing your top-level business information, including your name, address, phone number, opening times and web address. They are in local online directories, websites and across social media.
Google relies heavily on these listings (Google Business Profile, for example) to help find local businesses to include in their local search results.
By building your local listings, you are more likely to attract local customers and increase your rankings across the search engines for location-based searches. The listings will provide you with backlinks to your website, a crucial aspect of SEO.
Plus, the more opportunities to display your business exists, is open for customers and is locally well established, the more likely you will rank positively online.
