Backlinks are especially valuable for SEO because they represent a "vote of confidence" from one site to a different. In essence, backlinks to your website are a sign to look engines that others vouch for your content. If many sites link to an equivalent webpage or website, search engines can infer that content is worth linking to, and thus also worth surfacing on a SERP. So, earning these backlinks can have a positive effect on a site's ranking position or search visibility.
