it's no follow backlink

When you create backlinks to your website with Blog Commenting, if your website is optimized properly you will see a boost in your search engine rankings

you should comment on forum which has PR high to get quality backlink

I think so, can but few one use it excepted ^^

well. comment forum bring do follow backlink , it help your web have hign rank

Its very necessary to post comment on related blog only, which is relative niche to your site. Comments are no follow but you will surly get benefit if it after few time. Its very important to comment on only active sites.

hi,
i think you shoul choice coment on forum to get backlink easier!

Unless and until you comment on a website which haves good page rank and matches your niche you will not get any benefit. And if you find these matching criteria then also the website must be no follow atribute which adds very little impact.

I also thing comment forum better than blog

Blog commenting on the same niche sites may help you to connect with other blog owners from around the world. You may get traffic to your Blog too. But blog commenting is not a good way to build back-links. Almost all the blogs will give you No-follow back-links which will Not pass any link juice. Try to build back-links from Do-follow sites.

Blog comment backlink
 

You simple fill your link, that want to build backlink, and what you think about that article in the box comment under each article of blog comment

many blogs on blogger allow comments, you can just visit those blogs and put your comments, same is true for wordpress blogs as well. sometime blog owner moderates the comment before publishing them. some time you may have to enter captcha. try to put reasonable comments so that your link stays for longer time.

guess blogging is better

find and submit for do follow websites

Before you get all bent out of shape about how blog commenting is a horrible link building strategy, I want you to take a moment and approach this strategy with an open mind. What I’m talking about here is using blog commenting to build relationships and authority in your industry, and how those two things will ultimately lead to organic links and new traffic.
