In simple terms, SEO backlinks are links to a website coming from other websites with the effect of improving the website's search engine result page (SERP) ranking. For instance, if abcd.com links to a site wxyz.com, then the link will be referred to as a backlink by wxyz.com. They are also referred to as inbound links, inward links, incoming links or in-links.
