Technically, this might not be considered “advertising,” but one of the best things that a business can do to promote their business for free is optimizing for local SEO. This includes doing simple things like claiming your business listing on places like Google+, Facebook, and YP.com. But that’s just the first step. Once you’ve claimed the business, ensure the name, address, and phone number is consistent across all of these listings, that you’ve uploaded photos, and added your hours of operation—then start collecting online reviews.
Since guest posting on a popular blog allows you access to an established audience and high domain authority, this practice can sometimes be more beneficial than posting to your own blog. Plus, you can link back to your own website from your article, giving you an inbound link that boosts your domain authority and can increase your own website's ranking in search engines.
