Here’s what the DoFollow, CommentLuv, KeywordLuv, TwitterLink and Top Commentator WordPress plugins are and how they will help you quickly build back links automatically.
DoFollow CommentLuv KeywordLuv TwitterLink Top Commentator
Here’s a simple explanation of why it’s really smart for you to leave lots of comments on this blog:
Googlebot is the software used by Google, which collects documents from the web to build a searchable index for the Google search engine. Google finds and categorizes websites through the constant use of the Googlebot that is crawling millions of websites and blogs all the time.
Most websites and blogs restrict Googlebot from being able to follow all links it finds thanks to a default nofollow attribute. This means leaving a comment on those sites isn’t going to help you nearly as much as leaving one on this blog will.
DoFollow
The DoFollow plugin removes the automatic rel=”nofollow” attribute added to external links. This means that when Googlebot and other search engine spiders crawl this blog they will follow all links they discover including yours when you post comments! Pretty cool huh?
The more links to your blog or website the higher it will rank in search results and the higher your PageRank will be. This is why it is extremely important to get as many relevant backlinks as possible. This blog helps you do both automatically when you leave comments.
CommentLuv
This plugin allows me to reward you automatically each time you leave a comment on this blog by placing a link to your last blog post at the end of your comment. It works by visiting your site while you are typing your comment and retrieves a selection of your last blog posts, tweets or digg submissions which you can choose from to include at the bottom of your comment. For this plugin to work, you need to make sure you are logged on and have your homepage URL set in your profile page in the dashboard of your site. Make sure you go to ComLuvand register to maximize the benefit of this great plugin. 
Here’s how it looks:
Just below the submit button you will see the CommentLuv drop down menu opened up to display my last ten blog posts.
I can elect to use the default, which in this example is Complete 53 Volume Subliminal Library Special Offer or I can choose one of the posts below it.
Tip: Always choose a post that is most related to the topic of the post you are commenting on. This will engage more readers and give you the highest chance of getting clicks through to your site.
If you look at the name field of this image you will notice I’ve entered Britt Phillips @ Free Website Traffic Methods instead of simply my name.
On most blogs by default you can simply enter your name. Many blog owners will not approve your comments unless you include your name. I’m NOT that way. : ) You can enter your keywords in the name field with or without your name.
And this brings me to the next great plugin which is KeywordLuv.
KeywordLuv
This plugin is very easy to understand. When you enter your name @ your keyword(s) in the name field KeywordLuv automatically links your keywords to the website you entered into the website field. This gives you a backlink with Anchor text.
Look back at the above sample comment image. Look at the Anchor text I used… “Free Website Traffic Methods” this is the phrase that will be linked to the page on my blog where I’m selling a DVD that reveals over 50 ways you can get FREE website traffic! : ) 
Here’s a few examples:
In the first post the person entered king @ automobile accident attorney in the name field.
In the second post the person entered Mike @ Job Search in the name field.
In the third post the person entered Bowflex Treadmills in the name field.
In each example the KeywordLuv plugin automatically linked the keyword phrase to the website entered in the website field when submitting the comment.
Also, notice in the second comment just below Mike’s name, you also see his Twitter ID and it too is linked, to his Twitter account.
The next plugin is called TwitterLink and it’s pretty cool.
TwitterLink
This plugin is pretty simple to understand. You simply enter your Twitter account name in the Twitter field. The TwitterLink plugin takes your Twitter name and places it below whatever you entered in to the name field and displays it in your comment. People who read your comment can also click your Twitter name and be taken to your Twitter page! It’s a great way to generate more interest and followers.
Top Commentator
This plugin displays (in the right column of every blog page) the top ten contributors, the total number of comments they’ve made and their name. Notice in this example how Wayne used his name while Nath took advantage of the KeywordLuv plugin and used the keyword phrase Ipod 4 Touch. The plugin take whatever you enter in to the name field when you leave your comment.
Tip:If you would like to increase your comment count and have it displayed as a backlink on the Top Commentators widget in the sidebar of every page, make sure to include the same data in the name field.
So there you have it, several smart reasons you should leave comments on this blog and do it often.
Here’s what I look for when approving comments:
1. Good Comments – I’m looking for comments that offer creative insight, add to the conversation, enage readers and inspire them to reply thus keep the conversation going.
2. Relevancy – I’m looking for comments that are relevant to the post. Review the tags links on the right side of the page to locate relevant posts to comment on.
3. Offensive Links – If your comment includes a link to any offensive site it will not be approved.
4. One Liners – If your comment is a short one liner such as “great post”… “good job”… “thanks for sharing” etc. I most likley will not approve it.
If I’m going to give you a permanent back link I believe you outta at least take a minute or two and leave a good comment in return.

Hi Chris,
Absolutely! : )
Thank you for such a full review of all these wonderful plugins that make a blog very attractive for commentators. I always seek for such blogs, because I always leave meaningful comments on the posts that interest me, and naturally I want to get some advantage for myself, too. I think a link with keywords is not bad reward. That’s why KeywordLuv is my favorite plugin.
Hi Holly,
You’re most welcome. : )

How to you keep the real spammers from filling up you comments area. Even if you use something like CCAPTCA some of the pseudo software programs can get by it pretty quickly.
I always approve comments manually before they appear live. This is the only way to ensure spam doesn’t slip through.

Hi Britt,
Excellent tips you have here. These wordpress plugins has been very useful to the blogging community, not just with link building, but also in developing a blog’s brand, given that other readers will be familiar with the site of the commentator upon seeing their keywordluv links.
With commentluv, it’s definitely a great way to promote your blog’s recent entries, and also helpful to other commentators.
You’re also using GASP, great!
