I'm outsourcing the commenting on blogs part of my SEO campaign... I asked somebody if they knew how to find "Do Follow blogs"... This was there response: "Do Follow" blogs means I have to be informed every time that there is a response on a certain topic. hmmm, what do you think of that response???
NO!!! A Do_follow means that when a search engine crawl a site and sees a do-follow libk then it will follow that link and index it. so a dofollow link is a backlink. i host a do-follow blog, see my signature
Frankly, that is what I thought until a 13 year old kid come and advice me. He told me that why my blog have "U Comment I Follow" badge but my blog is not dofollow. So, I immediately removed the badge and started to learn about it. You can search in google for this. I'm sure there are plenty of posts made to differentiate and explain dofollow blogs. Now, I made my blog to dofollow and proudly place the badge again understanding the concept of dofollow. You can also check my blog under "PageRank" tag. All explained well there. DoFollow is only for Google to crawl and index in their database for future search engine results. For Yahoo, this does not make any difference as dofollow or nofollow, both will get indexed in yahoo search engine.
