Guest posting tends to work well as a marketing strategy because it benefits both the company contributing the guest post (the writer) and the company hosting the guest post on their site (the publisher). You're offering something of value in return for exposure, as opposed to having to either beg or pay.
Before we get into best practices for guest posting sites, here are the main benefits:
Generating backlinks that help with SEO. Website owners who accept guest posts often allow you to include a backlink to your website in return for your content, which is an excellent way to strengthen your backlink profile and increase domain authority.
Increasing reach (and traffic). Guest posting services will place your brand in front of a new and targeted audience. You'll be able to showcase your authority and get people who are already interested in your industry more familiar with your company.
