Link building is the process of acquiring hyperlinks between pages of a web site or between different sites. Search engines use links to crawl websites. There are several different ways to link build including starting a link tag or an anchor tag through opening the link, creating a link referral locations, visibly anchoring the text in the link and closing the link tag. Search engines use links to find new web pages and to determine where a web page should rank in their results. Through building up better links sites are able to increase their standing within a search engine and attempt to reach one of the top spots.
