A Webmaster Blog
This is what what Nofollow tagged link should be. It should be a way for Webmasters to tell the search engines that they have not judged the paid link by the user clicks and can therefore not assure for it’s information and value. It should not be a way for Webmasters to tell the search engines that the importance to the link was received. (ie, “I linked to you but nofollowed ”).
If you have verified the link and you are putting it on your site, do not put a nofollow on it. It is a bad form.
Now, on to what Google is doing to Verify links. Because Google has so much market penetration with Analytics, web history and the Google Toolbar, they can look at a link and verify it’s integrity (to some extent) by how many users actually click the link. If a link is relevant, it will have a higher clickthrough rate than one that is not. If a link is hidden or obscured, it will have a lower or almost non existent click through rate. In this manner, Google is using user behavior to verify the links.
And when you(GOOGLE) think about it, this really makes more sense. If a link is tagged “nofollow” but people keep clicking it and continue to surf when they get to the destination site, then who will you trust? The webmaster who put up a nofollow? Or the millions of users who click the link and seemed, at least algorithmically, to enjoy the content?
The answer is pretty obvious.

Dear friend, Will you please explain me in detail what a ‘nofollow’ link means? It if it is really not to be followed then why webmasters put it? And, clickthrough rate helps in judging whether the link to be followed or not? Though the questions are answered by you, I want some detailed explanation. Thanks in advance
