While it’s not fun or glamorous, it is important that site owners conduct a full link audit once a year. Depending on how long you have been engaging in link building, you might have thousands of links to sort through, but it has to be done. Digging through you link portfolio is important for several reasons. First off, it helps you identify any holes in your link building strategy. Do you have hundreds of links from blog commenting but only three local search profiles? Secondly, organizing your link portfolio will alert you to any “bad links” that are pointing to your site.
