what is use of blog commenting in seo ?

Blog commenting is a good way to diversify your incoming links profile. However it can have limited success if done wrong. First install SEO Quake, and enable line throughing nofollow links (no point in building a link if it is no follow which a high perfect of blogs are). Secondly add something to the conversation comments like "Get WOW Gold Here", "Great post.", and such add no value and do more harm than good in the long run as Google already penalized comment spammers (I believe Matt Cutts at one point asked for samples so...). And lastly don't go overboard this is just one tactic so don't build excessive links at once because with run of sites comments on a fair number of blogs it can give you ridiculous link acquisition. I once posted on a .gov blog and had a run of site for 3 months, that was the last thing I wanted as I only wanted one .gov link.

To add to the good advice drmadcow gave you here a few other tips

Try to find blogs that are relevant to yours. Relevant links have much greater seo value than non relevant links. Secondly if you spend some time on the other persons blog you may find a syndication partner

Throw some links at your blog comment links,this can be completely automated and throw a little more juice around.

Look for blogs that use "top commenter" plugins. This addon may give you a home page link which is usually the only page on the blog that has any real juice flowing through it

Blog comments work well as support (tier 2 or 3) links. Quality links are awesome but the backlinks that don't point directly to your site don't have to be the highest quality. But DO NOT point low quality blog comments directly to your website. Especially if your site is fairly new and you haven't had the opportunity to establish your sites authority.

When commenting on blogs make sure it's relevant to the blog you're commenting on. Also make sure your link is relevant to the traffic. It's safe to assume now that adding commenting to every blog in the world is no longer viable option unless you're speaking to the people reading. Hope this helps.

Blog Commenting used to be a real quick and easy way to get links, but the spammers got wind of this and blog owners became much more savvy, now you must have something relevant to say to the topic, which is common sense and it should add to the topic.
If you can follow those two simple rules, then you ca obtain some fairly quality links...it's also a good way to let people know that you're an expert in your field, thus increasing your brand awareness.
It's tedious work, but worth it if it's done properly.
