There’s this misconception amongst bloggers that every time they leave a comment on your blog that they are getting a free one way backlink.

Surprise! Not if you’re using Wordpress.

By default Wordpress puts the NoFollow attribute in your blog comments so when the web spiders come along they ignore the link, as far as Page Rank goes anyway. Thus you don’t pass along any link love to your visitors by giving out a free one way backlink.

If you want to give some link juice to your commenters you have to remove the nofollow attribute that Wordpress takes upon themselves to place in the source code.

One Way Backlinks are the most difficult of backlinks to get and for this reason require the most work to get them.

First off, all one way backlinks are not created equal.

One big determining factor on the worth of the link is where it comes from. You are going to want to get links from other sites that have a high page rank. Another key factor to making this link worth more is the relevancy of this site to yours. You want these links to come from sites that are on the same or similar topic as yours.
