What is Off-Page SEO?
Off-page SEO, or off-site SEO, refers to the SEO activities outside your website to improve your search engine rankings. In most cases, off-page SEO involves the creation of backlinks that point to your site.
Guest posting is one common tactic for getting backlinks. That is, you author high-quality content on other sites in exchange for a backlink pointing back to your site.
Off-page SEO contrasts with on-page SEO, which refers to the search engine optimizations done on your website. Together with Technical SEO and Local SEO (if you’re ranking for local keywords), they form the search engine optimizations you should engage in to improve your overall site rankings.
