Now we are getting to your off-page SEO. Off-page SEO is basically a measure of how popular you are. This is much harder to control, but it determines how highly your site will rank. With our SEO Grader, you have the option to know your total backlinks, referring domains, referring IPs and so on. Essentially, the more authoritative (a.k.a. popular) a site/platform that references your site, the higher your website will rank. It’s Google’s way of vouching that not only is your content quality, but also important to people.
