If blog comment is related to the topic then it is good.

Blog is very useful to increase traffic on any site.Always submit your comments on theme relevent blogs.

Thanks for the link Mr. Teewhy.

Commenting on related blogs is also a good way of promoting your blog, don't just post there be friendly and comment, post quality over quantity.

quality post? you mean related post on the blog you are commenting to..

This is a touchy issue too many ! I think it is perfectly ok to utilize blog commenting for SEO purposes and building backlinks.
However, as a responsible Internet Marketer you must keep a stringent balance in gaining backlinks to your own site while also being able to add substance to the community that you are posting the comment on !!
This is mandatory , and I think until you can do this consistently then you should stay away from blog/forum commenting (for SEO purposes) until you can !! PERIOD. IMHO

I dont think by commenting on blogs will bring you traffic but commenting on dofollow blogs will definitely brings you backlinks in a way PR.

If you comment on extremely high traffic blogs with nofollow, you will get some clicks that add up over time.

I commented on a popular post on Problogger about eighteen months back and I still get clicks coming back from that one post. Must be hundreds óf hits by now. And I was a way down the list, about the 25th or 26th person who commented!

If you can be one of the first to comment on an A-list blogger's post then you would get even more hits, I would imagine.

That is correct! And remember that it is a well read blog, because it is a good place to place a link to your website or one of your articles. Blogs are usually spidered more often than a website, so you will be able to get your information out to the public faster.

If you are the original poster or thread originator and the thread becomes popular you gain the most views and ranking.
