One of the most important aspects which Google takes into consideration when generating search engine results is how many qualified incoming links your site has. Gaining quality incoming links is also one of the most difficult things to achieve in effective search engine optimization. One effective way to acheive numerous incoming links with quality anchor text is to gain a link in another site's blogroll. A blogroll is a link manager built into most blogging software and online blogging systems such as Blogger. These links typically show up on the right or left columns in the blog. Why linking from a blogroll is so effective, is because when an author writes a blog post, that post appears both on the front page of the blog as well as generated as an individual archived page. This generates two disctinct links to your site and everytime the author writes a new post, another two links are created. Over time the links add up and are indexed by Google as qualified incoming links to your site. Although it is preferable to have many incoming links from many different sites, Google still considers these incoming blogroll links as being relevant and it will indeed boost your search engine results page rankings.
