Can you differentiate between ‘nofollow’ and ‘dofollow’ link?

To Follow Or Not To Follow, That Is The Question
So now that you know the difference between do follow and no follow links, which should you use on your site?
To know that, you really need to think about what sites you are linking too in your posts. The vast majority of them will probably be do follow links, as only by linking out to sites will you get sites linking back to you. Make sure that your do follow links are relevant to your post, anything that isn’t relevant could look spammy to search engines.
For anything that isn’t relevant, yet you want to include a link, a no follow link would be best. Also, make sure that any advertising links, affiliate links, sponsored links, etc. are no follow. You still get paid when people click on these links, but you don’t need search engines to follow them.
Another useful use of the no follow tag is when mentioning competitors. You may want to point out something on their site that is of worth, yet not want to pass any link juice. That is a call you have to make.
Lastly, if you run more than one website and want to link to each other on every page (perhaps in the footer), you’d probably be best making it a no follow link. Search engines may view it as being spammy if you use a do follow link for the same site on every page
