Blog comment Posting is Important in SEO work ?

It does help to some extent, though not dramatically.
Please note also that some will make your link with a "no-follow". try to post responses in places that do not do that. your work will be mora valuable this way

 

Yes but prefer dofollow blogs.

 

Blogs with do follow attribute will provide back links for your site so enhance ranking.

 

yes Do follow Blog comment Posting is important in seo. It's way to getting quality back links

 

Yes it is relevant blog then sure effective.

 

Blog commenting has been always good for generating links and gaining some referral traffic. I personally do it a lot and getting good results from it.

 

Some say blog commenting is a form of spamming. But links that are build from do follow blogs are consider as pr juice.

 

I think is is useful. Having more comment mean you have more fresh content and Google bot will love it.

 

It sure is helpful in building quality back links.Visit blogs in your own niche and make good and helpful comments.This will get your comments approved and the blog owner gets fresh content.Also, by posting good comments the other blog visitors will want to learn more about what you are doing and visit your site.

 

Yes... Blog comment is very important...If your comment approved, get a good back link...Try to send a comment meaningfully and more than two lines.

 

Yes its very helpful but if the blogs are do-follow.

I noticed one thing that some blogs which were Do-Follow earlier have now become No-Follow.

The comments you do should be general n not promoting your site.
