Recently, there's been a movement amongst bloggers to remove the NoFollow tags from comments posted on their blogs (What is NoFollow?). Removing NoFollow tags allows link juice from the URL included in your comment to be passed on to your site, helping it move up in rankings.

This post will help explain how to locate these DoFollow blogs and how to contribute a meaningful and successful comment. Doing this properly can land you high quality backlinks, while contributing to quality of the conversations across the web.

How To Find DoFollow Blogs

Search Google – While there are a number of resources available to help you find DoFollow Blogs, we've found that conducting our own specific keyword searches usually render most accurate results. Searching allows you to seek out blogs directly relevant to your interests or targeted keywords. The following query examples assume you are searching Google for blogs related to the keyword design.

How to Make an Impact

• Find DoFollow Blogs that Interest You
  It is very important that you read and understand the post in order to contribute a meaningful comment. If you are interested in the post you are more likely to have something relevant to add to the conversation.
• READ THE POST!
  For the love of GOD at least have the decency to read and comprehend what you are commenting about. All to often SEO’ers think they can get away with “Nice Post” or “Good Job” and leech the link juice from the page. Bloggers are not stupid and can spot this activity a million miles away.
• Use Your Real Name or an Alias
  Doesn’t it just feel wrong when you are writing a meaningful comment, and then leave your name as “Canadian Medical Supplies”? I don’t know anyone named Canadian Medical Supplies, but if you do, let me know and I will repeal my rant. Blogging is about conversations between people, not a black hat tool to dump your targeted keywords into. If you comment with a name or alias, you will still get natural link juice to your targeted url.
• Be the First to Comment
  Subscribe to RSS feeds of the blogs that you would like to contribute to. Once you receive notification that a new post has been added, try to be the first to leave a comment. You will not only receive your link juice, but you will get natural click throughs from the visitors reading your insightful comment. (Unless your comment is “Wow that was great. I disagree with some points, but others I agree with.”)
• Build a Relationship
  Most bloggers that allow external links are very picky about the comments they accept. If you are serious about getting a link from a particular blog, then spend some time reading and commenting on other posts within the blog. Authors appreciate your feedback, and you just might form a longer lasting relationship out of it as well.

Conclusion

While these tactics don't work all the time, they are at least a step in the right direction. I hope you use this post to enhance the quality of commenting and conversations across the web - the last thing the blogosphere needs is an army of black hat cronies spamming every blog they can find. Hopefully these tips will add a little life to the drudgery of link building by allowing you to actually learn about the posts you comment on.
