Actually comments are not a big factor for backlinks anymore. From what I understand the comments are barely noticed when it comes to backlinks. I can't remember where I was reading about that tho, but Google doesn't really consider them to be a good source of a backlink. That and many people have their commenting as no follow.Blog commenting can be a great way of getting backlinks. However you need to ensure that you are posting high quality comments on relevant blogs with lots of anchor text variations. It is best to manually post comments on authority blogs within your niche so that there is a high chance of comment approval. Also it is not a good idea to use automated tools like Scrapebox while posting comments unless you are creating backlinks to tier 1 links pointing to your site.

The problem is that a lot of sites are using no follow. Here is a good question and answer from seomoz about commenting for backlinks. It does say that it can be good but it can also hurt if not done right. I cannot remember where I was reading about the links from comments not holding as much weight anymore, but it may have been because many sites and forums use the no follow which provides no link juice.Can you provide a source for this information? As far as I know blog comments from high PR posts (not only sites) still help in ranking. Of course the post should have a low number of outbound links and the links should be dofollow.
Is blog commenting for SEO spam?
