just relized i wrote on wrong topic. Actually i mean to write on an "auto article submitter topic". Almost all blog has pr are using nofollow. so i dont know.
First of all you select the blogs which is related to your site and post the 'valid' comment that is you read the blog post and post your comments in two or three lines minimum. For that comment posting normally first you give your name, then email then home page or url? here you give your url. So, it will take a back link once your comment is get approve means.
Unfortunately, it's normal practice for websites to have blogs and there're lots of blogs who just won't approve you, no matter how relevant and good your comment is. I've been to many dofollow blogs who keep it dofollow so some people will visit them.
you can find a lot of blogs that do approve its just need some intelligence to find them creatively in google.
I am very much confused whether from blog links i will get traffic or not.. Some says its a spam work and totally use less. Any one can clear me how much traffic comes from blog links??
Just choose a relevent Keyword related to your site.Use this keyword in place of your name.Link it wit your site by filing the url/website field. Type your comment related to th blog post.You can also add html code to show your link in Comment.But make sure that your commenting anchor text should be do-follow.
