One-way back link is a term often used among webmasters to describe link building methods. It is a hyperlink that points to a website without any link back from that site. It is suggested by many seo experts that this type of link would be considered more natural by search engines. One of the designed purposes of the Web is to allow authors to link to any published document on another site. The possibility of so-called "deep" linking is therefore built into the Web technology of HTTP and URLs by default.
