I have a lot of folks asking me personally about the effectiveness of blog commenting as a link building / SEO technique, so I'd like to express my thoughts and opinions on the topic. I personally think in blog commenting, and have enjoyed great SE results from this method, however and this is a large but , it must be done correctly. This how:

Contribute, Don't Spam

If you think you're gonna get easy hyperlinks by just writing a really generic message, and posting it to countless websites using something like Comment Kahuna (or something similar), you're wrong. Most weblogs will simply flag you as spam (assuming you work through the Captcha code), and those that do accept you probably will by poorly maintained sites that carry very little SEARCH ENGINE OPTIMIZATION value in any situation.

If you want to get that link, you have to work for it. And its really not that hard. Simply read through the article, and draft a quick, worthy response, that adds value to the blog. You can even ask a question you may have on the topic as this too adds value. Now Now i'm not saying that you'll always get a link this way (because there are some nasty moderators out there), but this strategy is far more likely to win you some link juice.

Forget About NoFollow

The "nofollow conspiracy" as I call it is highly overated. Don't waste materials your time looking solely for sites that apply a "dofollow" comment coverage. Rather mix it up and comment where its most appropriate. Looking for only the best, high PageRank, "dofollow" weblogs will probably spend so much time that you could have used building backlinks or otherwise marketing your business.

Get A Gravatar

This one's more an thoughts and opinions than anything otherwise, but since a moderator, I always look for feedback which have Gravatars (avatars) to add to my blogs. Not only are they more colourful and fascinating, but chances are that someone who's taken the time to set up an avatar is less probably a spammer.

Link In order to Something helpful

Don't always just use your root domain - if the blog post is about something that you have more info about on your site, link to that webpage instead. This adds more value to your remark, and also diversifies your backlinks, ensuring a "natural look".

Spread It Out

Getting backlinks from the same websites over and over again isn't really that useful. Aim to get a few hyperlinks from a variety of blogs, and diversify your linking websites
