How To Turn Your WordPress Blog From NoFollow to DoFollow Without a Plugin

DoFollow In this tutorial, I will show you how to easily turn your WordPress blog from the default NoFollow to a DoFollow blog without the need of a plugin. Why not turn your blog into a DoFollow blog and get more visitors, more traffic and eventualy more recognition in the Online community. Probably you already have seen some blogs displaying the DoFollow image and you wonder how it is done and what it really means. Read my next tutorial for a closer look at DoFollow versus NoFollow.

What are NoFollow and DoFollow?

DoFollow is a term that does not really exist. It is a slang term given to Websites that are not using nofollow. nofollow is a value that can be assigned to the rel attribute of the HTML anchor tag to instruct some search engines not to pass on any influence to an outbound link. The nofollow value was intended to stop comment spam in blogs. Commenting is recognized as a good way to get one way backlinks. But it has been abused and thus the creation of the nofollow value back in 2005.

You might already know that NoFollow blogs do not carry any PR value to other Websites through commenting. If your blog is DoFollow then comments made by your users get Link juice, meaning that your blog passes on the PR value to the commenter.

Should You Set Comment Links To DoFollow?

One way to encourage your readers to comment on your blog is by making your blog DoFollow. If your blog is new and you are trying to increase traffic then you need to turn your blog to a DoFollow blog. When people comment on your content they are adding value to your content. Some consider DoFollow as bribing visitors for comments, while others consider it as rewarding visitors that leave a comment. I tend to agree with the latter, but whatever your opinion is, DoFollow encourages interaction with your readers. One negative side though is that it increases comment moderation duties and an increase of spam comments.

What About a Plugin?

Yes, there are several plugins that turn your blog to a DoFollow blog. But I encourage you to read my previous article about unnecessarily adding plugins to your theme. Also, you really don´t need a plugin for such a simple task.

How does NoFollow and DoFollow Look Like?

The only way to know whether a link has been set to NoFollow is to look at the source code of the page. There are several ways to do that depending on the browser you use. To look at the source code, select “source” from your browser´s menu or you could right click on the page to view the source from the context menu. Also, Mozilla Firefox browser has add-ons that highlights a nofollow link on the page without actually looking at the source code.

The attribute that defines a link as NoFollow is rel=“nofollow”. If you remove the rel=“nofollow” attribute, then your link becomes DoFollow. There is no dofollow value. The absence of the nofollow value makes the link a DoFollow.

A typical DoFollow link is like this:

<a href="http://blueoliveonline.com/" title="">Blue Olive Online</a>

A typical NoFollow link is like this:

<a rel="nofollow" href="http://blueoliveonline.com/" title="">BOO</a>

Features of My “DoFollow” Code

  1. The code is added to your theme´s functions.php file. The core WordPress code is not modified in any way.
  2. The code is split into 2 independent sections (Section1 and Section2). You have the choice to choose either one or both.
  3. The code is tested to work with the latest version of WordPress. However it also works with earlier versions.
  4. The code is tested to work properly with all major browsers.

“DoFollow” Code | functions.php

To change your Comment links from NoFollow To DoFollow, Open the functions.php file located in your theme´s folder, and add (copy and paste) the following code.

Note: To scroll within the code: You can also click on the code window and use your keyboard´s arrow keys.

“DoFollow” Code Notes:

Note: If you don´t see the horizontal bar, and to scroll within the code, you can also click on the code window and use your keyboard´s arrow keys.

1. Section1 of the above code changes the author´s link in the Comment section to a dofollow instead of the WordPress default of nofollow.

Meaning an Author´s link such as:

<a class="url" rel="external nofollow" href="http://boutrosabichedid.com/">Boutros AbiChedid</a>

will be transformed to:

<a class="url" rel="external" href="http://boutrosabichedid.com/">Boutros AbiChedid</a>

2. Section2 of the above code changes all links in the Comment text to a dofollow instead of the default WordPress of nofollow.

Meaning Any link in the Comment text box such as:

<a rel="nofollow" href="http://blueoliveonline.com/">Blue Olive Online</a>

will be transformed to:

<a href="http://blueoliveonline.com/">Blue Olive Online</a>

3. You have the choice to apply either Section1 of the code or Section2 or Both. For this Blog, I applied both Sections.

General Warning

When you add several PHP code blocks in your theme´s funtions.php file, make sure that you do NOT leave any white space (spaces, newline) before the opening PHP tag or after the closing PHP tag. Like so (the correct way):

<?php 
//Some Code here beetween the opening PHP tag (above) 
//and the closing PHP tag (below)...
?>
<?php 
//Some other Code here ...
?>

In the above code, if you leave any white space or a newline between lines 4 and 5, you will get the following error: Warning: Cannot modify header information - headers already sent by … , in your login screen and after you login to your WordPress dashboard.
