I know you are wondering what I'm talking about. Ok so some of you probably already know, but I didn't until today. I saw a lot of those on people's blogs so I was always very curious. Basically it's a way to get spiders (not the eight legged kind) to pick up the links. This is good for me as well as my readers leaving comments on my blog. I wanted to post that I am now a U Comment I Follow blog, and I also changed my 3 other blogs so comment away readers!
If you are interested in doing this and then go to edit HTML in either wordpress or blogger. It's near the bottom and look for the < href="data:comment.authorUrl" rel="nofollow"> and remove the rel="nofollow' and click expand widget at the top box of code. You will also want to put a widget like the one above. To find more click on this great blog Randa Clay. She has some different colored ones. Just right click to save to your computer. While there, click on the site that shows you exactly how to modify it for blogger. It's very easy. I hope you join the revolution!
