Backlinks are incoming links to a website or a web page i.e. links which are linked to that website or webpage. This is an indication of the popularity or importance of that website or that page and also helps to determine the relevancy of the page. As per the number of backlinks to a website, the value of the website for search engines is evaluated. The backlinks to a page indicates how much people are interested in that page. It also means that if your site or a page in your website has many backlinks then many webmasters or bloggers are paying attention on your website or to that particular page. Backlinks are also called as inbound links, inlinks, incoming links, and inward links.
Search Engines use these backlinks of a website to determine how relevant the site for a particular keyword is. The number of backlinks to a website evaluates its importance to the search engines. Websites often employ various techniques (called search engine optimization) to increase the number of backlinks pointing to their website. Many times Search Engines index your site whenever they get a backlink to your site from another site. So as many links pointing to your site, your site gets crawled that many times. This also helps you to keep your site always updated at the search engine’s index.
The value of a backlink to a website or page is determined through several factors. Not only just having some backlinks fulfills the job of getting importance in search engines. Search Engines provide high values to backlinks from authoritative sites on a given domain. Only relevant backlinks are believed to have strong influence on the search engine rankings of a webpage or website. Another important factor which determines the importance of a backlink is its anchor text through which the page is linked. Anchor text is referred to the text used to hyperlink a webpage. Search engines use to check the anchor text and the content on the linked webpage to confirm relevancy. The Search Engines also expect a relevancy between the content of the two WebPages which are linked.
So, from now try building up as many backlinks as you can for your website and take your site higher in the search engine rankings. This process of building backlinks to a website from different sites is called link-building. So to make sure that your site comes up in Search Engine Results Pages (SERPs) you have get some backlinks from sites which have relevant content and link your pages with similar anchor texts. The sites which provide content similar to your website are called good neighbors and those who are different from your domain are called bad neighbors. So try to build backlinks from good neighbors and get good search rankings.
Remember one thing, backlink to a webpage doesn’t improve the ranking of the whole site directly, it improves the value of that particular page only. Then those good ranked pages of your website help to bring up the whole website. So if you are building backlinks to your website then try to do it all over your website and not just to particular 2-3 pages.
