Install an addon in firefox to know if the link is dofollow or not. Here's the link: https://addons.mozilla.org/en-US/firefox/addon/5687/ Code (markup):
The easy way is ti press control + u and search for nofollow, if you do not found it, that means it is do follow..
You can also use the SearchStatus and NoDofollow add on for your browser. It highlights all links. If the link is in red, it means nofollow then if violet then it is a dofollow link.
If you use firefox, then there's an add-on, which will guide you. It will show up no-follow links striked with a line. Or you can simply check for the source code and then find out whether it is no-follow or do-follow.
If You find the no follow attribute in your source code , then is no follow, otherwise it is do follow.
Install search status plug in, it will tell you if the link is do follow or not, plus it shows the page rank and Alexa ranking
I use the QuickSearch plugin for firefox. It's got lots of other useful things, such as PageRank, Alexa ranking, etc, all in one toolbar.
