I need to create some no-follow links but don't have the idea about how should I create those and where should I put those links. Is there a list available to sites where I can create those link and can anyone guide me to a web tutorial or a link/site from where I can learn the process. Please share if you have the idea. Thanks everybody.
Why you like to create nofollow link, as this is not such SEO friendly? If you’re trying to get back links by posting comments on blogs your work may not get you the results you’re looking for if you post comments and links on blogs that use nofollow. But if you still like to know more about nofollow link you can search it at Google. You can find so many helpful topics about this there.
To add "no follow" you need a line of code, which you can find what you are looking for at w3schools online. Just go there and search for "no follow" tag.
Nofollow has one and only one legitimate purpose, and that is to discourage spammers on websites you control where there are unmoderated posts. If posts are moderated, or the content containing the links is checked by an editor, they should not be nofollow. Any other use of nofollow will just harm you--fewer people will want to contribute to your interactive websites, comment on your blogs, and you will see your search rankings fall if you start using pagerank in an attempt to "sculpt" the flow of pagerank through your site (I've never seen any hard evidence that this actually works either, it just seems to harm you). My website uses nofollow very sparingly. Usually, if I'm tempted to "nofollow" a link, I just leave it as a bare text URL, not a live link. If I don't trust a link enough for search engines to follow it, I don't want to encourage humans to follow it either, and I just leave the link as bare text.
It's good to have a balance between dofollow and nofollow links pointing to your website. This looks more natural to google. Hope that helps,
