Every SEO (Search Engine Optimization) effort must be accompanied by a link building campaign to be effective. After all, the incoming links are the entry points into any website along the links displayed during a search result on Google or any other search engine. There are different ways of building links and undoably the most preferred method must be the natural way of linking that attracts a visit to your website in search of good content. However this is a slow process and can take much time and effort though one can not deny that "content is king" and good content creation is one of the best SEO techniques ever.
Another common route of developing links for a website has been the reciprocal link building method where two or more websites exchange links with each other or links are purchased via a vendor. This method of search engine optimization is not appreciated any more by Google and such a practice will result in the site being blacklisted or it will get the website's ranking to be slashed down.
Web directories like Dmoz are human edited and are therefore well respected by the search engines. There are many directories with well categorized listings that are referred by people. While Dmoz is a free directory, there are many other paid directories that can be approached and this process can help in multiplying the incoming links to our website. One of the most common mistakes people make while submitting to paid directories is going for bulk number of directories that have no intrinsic value and are in no way related to our line of work. Such kind of linking if any will only create an adverse effect on the website.
One of the most effective linking strategies is to purchase text link ads from other high ranking websites. It has got a double benefit as the advertisement itself will pay by bringing in traffic and the site will get good ranking on the SERP (search engine results pages). Business websites can register or place an ad on online yellow pages and this also can generate good traffic within generating business.
