Off-page SEO, also known as off-site SEO, describes optimization techniques that can improve your ranking in search engine results pages (SERPs). These techniques, however, happen outside of your site and involve attracting links from other websites, shares on social media, and mentions across the web.
Off-page SEO is an effort (such as through social media marketing or influencer marketing) to generate links and ratings, so your site rises in credibility and rank. Off-page SEO is out of your control.
Why does off-page SEO matter?
Off-page SEO is tremendously valuable because it tells search engines that your website is important to others on the web. Every link that you receive acts as an endorsement from another source that your website is quality.
This lets external sources act as tie-breakers for websites that have the same quality of on-page SEO so search engines know the best to rank websites on search engine results pages (SERPs).
Search engines like Google measure off-page SEO factors, like the number and quality of backlinks to websites.
