It is used by search engines such as Google to determine a site content’s relevancy. The more links point to your site, the more relevant the site and hence, higher your ranking on search page will be .

While having a high page rank is vital to the popularity of your site, back links also contribute to driving quality (targeted) traffic to your site.

There are groups of websites where they hyperlink to each other in order to get lots of back links . Those groups are known as “link farms”, a form of spamming in order to get on the index of search engines . It could be done either manually or automatically . This method seems to be unscrupulous and unfair because it influences the search engine index.

Of course, your website won’t be banned by Google for using link farms. Search engines are able to identify and filter pages that are suspicious of link farming, and those pages will be removed from the search engine index to prevent them from entering the search results.

To do it the right way, make sure that the back links that you insert are placed on sites with quality content, and they are of same niche as yours, with similar content, targeting the same audience. Anchor relevant and important keywords to attract more quality traffic to your site.

Keep track of your backlinks to see how many have been indexed.

You can create more backlinks through Article Marketing by submitting quality articles to articles directories with a link to your blog or websites. Other methods include social bookmarking, publishing RSS, commenting on other blogs, participating in forum discussions, creating a post containing links on your blog and making sure they are related to your niche.
