Link building is an important part of search engine optimization and some bloggers do this at all costs, even to the point of spamming on other blogs. Having quality, one-way backlinks pointing to your site does a lot in increasing your google page rank, thereby increasing the chance of your blog appearing in google search results. What most people fail to know is that only the quality of the backlinks matter, not necessarily the quantity. It’s quite possible to have just a hundred backlinks and rank higher than sites with thousands of backlinks.
Now, don’t get it twisted, a high google pagerank doesn’t always equal to your traffic but it’s still good to have it anyway. It’s one of the algorithms google checks when sorting out search results. It’s always been said that original contents matters a great deal and you must take this even more serious than link building but that is not the main topic here. There’s a more comprehensive post I recently wrote on how to increase your google page rank and alexa traffic rank, you should try reading through it.

There are several ways to get quality backlinks pointing to your blog and one of the most effective is commenting on blogs relating to your niche. I’ve seen quite a lot of bloggers commenting here even to the point of spamming but most do not realize that google will never index or follow those links because there are ways to make blog commenting work to your advantage.
DoFollow And NoFollow Backlinks
What are dofollow and nofollow links? Did you know you can comment on 100 blogs without google recognizing any of those precious backlinks you worked hard to get? In a bid to reduce spamming for the sake of SEO, google devised the nofolow and dofollow tags. A link with nofollow tag added has no SEO benefit for the destination site and a link with dofollow or none of the tags will be indexed and counted as a backlink for the destination site

By default, all comments posted on blogs hosted on blogspot are nofollow links. Google doesn’t index links on most blogger blogs, you probably would have noticed that in google webmaster tools and wondered why.
How To Differentiate Between Nofollow And Dofollow Links
Before you go about commenting on just any blog, you should know whether the blog you’re commenting on has any SEO value for you. There’s a firefox extension that highlight links in a page according to nofollow / dofollow status.
There’s an easier way to do this though, just highlight an existing comment using firefox, right click and select view selection source. Below is an example of a nofollow link as shown in page source:
<a class=”says”>says:</a>
I’m not saying you should only comment on blogs with dofollow links, commenting on a few blogs with nofollow tag creates what looks like a natural profile in google’s view.

Thanks for information.

Do follow links plays a vital role in strong baclinks. So if you will get links from a do follow site Google will consider this.
Good job, but I think it's not enough.
I agree that it's a good idea to get some nofollow comment backlinks as well. If you just comment on those blogs that you are interested in, then you're sure to get a mix of both kinds of links.
Another way to get a combination is to post free classified ads that allow backlinks. The vast majority are nofollow, although some are dofollow.
Thank you

Thanks so much for this! I haven’t been this moved by a blog for a long time! You’ve got it, whatever that means in blogging. Anyway, You are definitely someone that has something to say that people need to hear. Keep up the good work. Keep on inspiring the people!
Don, follow links are awesome. However if you only get follow links, paid for, and don’t equal or more nofollow links it appears unnatural to the big g and they may penalize you for doing black hat seo.
Just my two cents.
