I have placed Digg buttons on all my post permalinks. I am hoping that some of the more topical entries will get some traffic benefit from this small change.
Another change that I am considering comes courtesy of Tyler Cruz. He didn’t invent Optimal Title but he brought it to my attention and I think it is a great idea. This plugin puts the post title in front of the blog title. Take a look around and see which high ranking bloggers arrange their titles in this way. There is an SEO benefit.
