What is a Backlink?

In search engine optimization (SEO) point of view, a backlink is a hyperlink that links from a Web page, back to your own Web page or Web site. It is also known as an Inbound Link (IBL).  Google counts these links for determining the popularity (or importance) of a web site. Backlinks tell search engines like Google, yahoo and Bing how popular your website is.

                                                                               

A backlink also plays an important role in gaining good page rank. Google considers the quality and quantity of backlinks to determine Page Rank. So, it is a good practice to get backlinks from do follow and high PR sites. Note that a natural backlink is more valuable to search engines than reciprocal links, and they are harder to get.

For example – If you are the owner of website A and your website is added in website B then website B’s link is backlink for your website.
