What this phrase means, is that the blog owner has turned off the NoFollow command in their blog, thus allowing the Googlebots to follow the comments and thus give a little love to those that take the time to comment on your blog. When the NoFollow command is in place, the Googlebots do not follow your comments, so any links you may leave are are not followed and are useless.
For a more indepth account as to why the NoFollow attribute is in place, I will leave it to someone who knows what they are talking about:
After I removed the NoFollow attribute, I posted a comment in my sidebar to let my readers know just what I did (well, you can actually just look off to the right-side as well. I know, it’s late and I’m tired)
- As a Thank You for those who comment, I have done the following:
- Comments on this blog are now made DOFOLLOW for the Google Spiders.
- Comments are moderated.
- Spam will not be tolerated.
Now, if you are interested in turning your blog into a Dofollow site, the first thing you will need to do is go into your html and click "expand widgets". Next, I suggest that you save your template.
Look through your coding until you come across this...
Where you see the rel='nofollow' just remove that portion and save the changes. Your site is now a Dofollow site.
