Guest posting is the practice of writing articles published on external sites in your niche, earning in return dofollow backlinks that increase your domain's authority.
Guest posting (or guest blogging) means contributing a quality article to someone else's site in a related or similar field, receiving in return one or more links to your site. It is one of the most effective white-hat link-building methods: you earn dofollow backlinks from real editorial content, on sites with a relevant audience. Google considers guest posting legitimate as long as the article adds real value to the reader and is not just a vehicle for links.
A single guest post on a site with DA 40+ can transfer enough authority to push pages from the top 20 into the top 10. The quality of the host site matters more than the quantity of links.
