Anything that you can’t directly control about your website is considered off-page SEO. Some refer to this as “earned” media, which can include social media mentions, backlinks, and reviews.  Off-page SEO is important because search engines like Google use indicators such as backlinks to analyze how authoritative your website is. If you write several blog articles in a month that go in-depth and provide true value to your target audience, then people will start to link back to your website or share your articles via social media. 

An off-page SEO strategy helps your website build backlinks, reviews, and social media mentions so that these indicators can send better signals to search engines for ranking purposes.
