Now there is not widget installed here that brings visitors to this blog, however, as has been experimented on several other sites, having the keywords in the title of this post will be the right keywords in to bring in more visitors. Perhaps you are one of them? Again, content is key to any high ranking, high traffic site.
A recommendation that I have for blogs as well is to join in on the dofollow movement. Dofollow refers to removing the 'nofollow' tag in the code of the comments section of a blog. The 'nofollow' tag makes it impossible for search engines to pull out link information that a commenter has left on a blog, and therefore taking away the reward of the commenter. On this blog, you will see that the 'nofollow' tag has been removed, and yon the top of the page you can see the badge that reads "U comment I follow" letting readers know that the tag has been removed. This should help reward visitors with a link for visiting and commenting on the site.
