Backlinks

Links from other websites pointing to any particular page on your site. Search engines use backlinks to judge a site’s credibility; if a site links to you, the reasoning goes, it is in effect vouching for your authority on a particular subject. Therefore, Link Building is an incredibly important part of Search Engine Optimization. How many links, the quality of the sites linking to you, and how they link to you all are important factors. Also called Inbound Links.
