Off-page search engine optimization is not just about building backlinks though.
It goes deeper than that. For example, brand mentions (your site URL or brand name mentioned on another site without a hyperlink) are an integral aspect of off-page search signals.
Off-page SEO simply tells Google what others think about your site. For example, if you’ve got a lot of valuable links pointing to your pages, search engines will assume that you’ve got great content that provides value for users.
People only cite, reference, and share content they like. Even in a brick-and-mortar business, if your product is helpful and affordable, you’ll get a lot of word-of-mouth referrals from your current customers.
Though many people associate off-page SEO with link building, it goes beyond that. Many activities that don’t result in a standard link on other sites are important for off-page optimization.
On-page search engine optimization happens within the site, while off-page SEO happens outside the site. If you write a guest post for another blog or leave a comment, you’re doing off-page site promotion.
