If you are using Firefox as a browser, you can use the "SEO for Firefox" plugin, which will highlight in red if a link is no follow, so it is easy to identify at first glance. A link to the plugin is: http://tools.seobook.com/firefox/seo-for-firefox.html - It is free to download. Hope that helps
There are lot of plug ins like search status & seoquake in firefox to know the nofollow links,but you can also check it by looking at the nofollow attribute at source view page.
I am using Firefox and installed the "SEO for Firefox" plugin so I can easily see if they are dofollow or not!
Just go to the page source of your webpage. Press Control + F to find for rel =â€nofollowâ€. If it is there, your site has a 'no follow' attribute, if not, then it has a 'dofollow' attribute.
Look out for the page source of any web page. Press Control and 'F' to search for rel=â€nofollowâ€. If you are able to find then the site is a nofollow site, else it is a 'dofollow' site. Isn't it that simple?
