Do all search engines give credits to links / PageRank?
Yes, all search engines give credit to quality incoming links. PageRank is a term coined by Google. Other Search Engines might call it differently but most of them do give weight age to this concept. A link pointing towards your website translates into external opinion on your website. It is an off page factor to determine whether your website is relevant. If a search engine finds a link pointing towards your website, it gives your website the weight age or value of that incoming link based on the quality and relevance of the incoming link.
