The battle for internet supremacy all boils down to search engine popularity. If a website can easily be found by search engines, such as Google and Yahoo, it has greater chance of being economically viable. Ideally, a website link must be displayed within the first page of search engine results. Would-be buyers and clients tend to click one or two of the ten first links displayed by search engine results. This is why high page rank is very important to commercial websites that are selling products and services on the web. This is the primary reasons why web-based companies are spending fortunes on search engine optimization or SEO. When it comes to this aspect, the "nofollow" and "dofollow" links are important issues.
SEO is all about being found in the web. Given a particular keyword search and category of a website, SEO techniques increase the probability of a website being found by its target customers or clients. Considering the number of existing websites, SEO is not an easy task. Many companies invest on link building and content development to maximize their web presence. By default, all backlinks to a particular website are "dofollow" links. These links are counted by search engines as vote for that particular site. Backlinks from blogs, forums, and social networking sites are all considered as votes. The more "dofollow" backlinks a website has, the higher its ranking in the search engines.
DoFollow Link:
On the other hand, some web developers may include "nofollow" links. This is done to instruct search engines to ignore the link as vote for a particular site. In this manner, spam links are prevented from being indexed by search engines. The quality of search engine results are thereby improved.
NoFollow Link:
