When you add a comment with your url in it to a blog post, will that give you a backlink? Does googlebot even go to comments of blog posts?
no, bacause major blogCMS automatically add nofollow tag on their comments, although there are plugins for WP that can remove this tag.
Googlebot goes to this page, and can even index it, but while it is nofollow, it won't give you a backlink and won't increase your PR or SERP ranking.
I have a list of nearly 1000 related blogs that don't use nofollow. More and more blogs are actually removing nofollow nowadays.
If suppose I created a blog with wordpress script.. Is this comes installed - "comments are nofollow" in default ?
most of the ig blogs are adding nofollow tag to their outgoing links. when googlebot see links with nofollow, it will ignore these links
Yup some fairly popular blogs, sub 30k alexa don't use nofollow, example http://andybeard.eu 20k alexa. You can find blogs who don't use nofollow using technorati, the most popular plugin for removing it is this dofollow plugin. Here is a list of 170ish, and a bumpzee group of 90 or so. But like i said above its easy to use technorati to find 1000's, lots of blogs contain lists of other blogs who have removed nofollow. Ive seen good results using blog comments for SERPS, especially when you can use these blog comments to link to your DEEP pages.
Depends on whether the author of the blog has removed "nofollow" tag. If the no follow tag has been removed, then you definitely will get a link back otherwise you wouldn't profit a bit All Success, ~G
Some blogs use the plugin Dofollow. You want to add your precious comment on these! Comment also give you the attention of other bloggers, don't forget that.
I use a nofollow plugin for my blog, when I check the comment to see if I want to delete it I can optionally add nofollow on a case by case basis. Any serious comments (non spam) that have a family friendly link back to their site I will leave without the nofollow. Doesn't hurt me so why not leave the link
This is how to do it. Well done mate. We should reward non spammers people who comment to out blog. Man, I hate spammers. I delete hundreds of messages everyday (in my email softwares and my own forum)
