Right-click on the browser page and view the source code. Do a search in the source code for "nofollow" ...if nofollow exist then its a nofollow page, if it doesn't exist then its a dofollow page. There is one catch to this, when you search there needs to be an existing external link on the page to get accurate results, unless the nofollow is in the header meta tags -- for the search engines to ignore the entire page.
this greacemonkey script shows follows and nofollows in different colors as you browse the page http://www.joostdevalk.nl/code/greasemonkey/nofollow-display/ first you need to install greacemonkey script on firefox, if you dont have it.
SearchStatus is the verygood with firefox. and SEOQuake is the better for all the solution with Firefox. i will suggest you to use seoquake with your firefox browser, it will show you all the details in just one click thanks John
Hey John. You right, I use the same, But some time, I have seen External Nofollow not counted by SEOquake as Nofollow .
I also use SeoQuake: There many guys who actually do link exchang with nofollow links all over their resource pages..
I like how in firefox you can just highlight a section of the site, right click and "view selection source" .. makes it much easier than digging thru source code.
