Dofollow and nofollow are the link attributes attached to a link on any website to assist the search engine about its quality. Webmasters use this service heavily to tell search engines whether the link posted on their website is a reliable one or not. It helps the search engine to determine if the website wishes to link their page to the mentioned link, so that the visitors could have more information about their desired topic.
The dofollow link on a website means that it thinks that a link is credible enough to be listed on their website and they would recommend other users and search engine robots to follow this link. This is great for the link which is followed because this would increase its traffic and page rank in Google, on the other hand no harm would be done to the one who mentions this link.
NoFollow is a hyperlink value that tells search engines not to pass on any credibility or influence to an outbound link. Originally created to help the blogging community reduce the number of inserted links into a “comment” area of a blog page, the attribute is typically standard in blog comments. It helps overwhelmed webmasters disallow spammers from gaining any kind of advantage by inserting an unwanted link on a popular page, and has become an integral part of Google-specific SEO.
As a result of the implementation of NoFollow, the process of building links has taken a steep turn.Many sites, including wikis, social bookmarking sites, corporate and private blogs, commenting plug-ins and many other venues and applets across the internet began implementing NoFollow. This made effective link building difficult for both honest people and spammers alike. It also made DoFollow links become the “Holy Grail” of SEOs everywhere, who seek them out as expensive collections to their off-site optimization repertoire.
What Is The Difference?
Nofollow links attributes do not allow search engine bots to follow link.That means if the website owner is linking back to you with nofollow attributes, it does not pass on link juice. Only Humans will be able to follow the links. Though some time back Google made it clear that they don’t consider nofollow link attributes but weight of such links are really less.
Example of Nofollow Link:
<a href=”http://www.linksbuild.wordpress.com/” rel=”nofollow”>Google</a>
Dofollow links allow Google (all search engines) to follow them and reach our website. Giving us link juice and a backlink. If a webmaster is linking back to you with this link both Search Engine and Humans will be able to follow you. The best way to give someone dofollow love is allowing keyword in the anchor text. This means when you are linking to any website or page, use the targeted keyword as anchor text.
