Many of you are not aware of the importance of NoFollow and DoFollow links. It is the one of main factors in deciding your search rankings as well as search position in search engines. Here, I will try to provide you the information you need to know about the both type of link attributes.
Definitions of Nofollow and Dofollow links:
Nofollow is an attribute value of a link, which tells search engines that the link should not influence the target-link’s ranking in the search engine’s index and should not crawl towards the target link.
Dofollow is completely opposite of Nofollow. To make a link Dofollow, you don’t have to use particular Dofollow attribute in the links. Search engine bots will crawl through the Dofollow links and PageRank juice will be shared by your site (that is what Google wants!)
Example of Nofollow link:
<a href=”http://www.thegeeksclub.com” rel=”nofollow”>The Geeks Club</a>
Example of Dofollow link:
<a href=”http://www.thegeeksclub.com”>The Geeks Club</a>
Here in the above dofollow example link, you can understand that, dofollow is default attribute of a hyper-link.
Nofollow was used (some sites use it now) to reduce search engine spam as well as comment spam. Some so called experts used it to control the PageRank of their websites. By using Nofollow link attributes, they were able to control the PageRank juice inside their blogs only, rather than passing it to the outbound links. But, Google had changed the algorithm in such a way that you can’t control your PageRank by using Nofollow link.
Google also suggests that, you should use Nofollow link attributes to paid links and affiliate kind of websites. So, keep your affiliate links behind the Nofollow attribute. Do not directly post your affiliate links to your blogs and websites.
In WordPress, comment field has built-in default Nofollow link attributes. So, don’t worry of your comment field links. But, I suggest do not make all your links as Nofollow because it too may affect your search engine position adversely. Think, if you are accepting the guest posts and you are not providing the link juice to your guest author. Will they come to your blog to write guest posts?
I am not completely agreed on making your blog as Dofollow. If you do it, then you should be able to tackle the spam comments by using Anti spam plugins and security plugins for spam bots.
But, Dofollow blogs encourages more comments. But remember that those who comment in such cases do so because of the dofollow attribute and not necessariliy because they may have something to see. But yes it does encourage commenting by bloggers.
I personally have made my all blogs as Dofollow and my PageRank has not increased, but search positions are good and getting more regular comments.
Now that you know what this means, will you make your blog Dofollow or Nofollow?
