I have used ‘rel=nofollow’ attribute to few pages of my site for which I don’t want the PR juice to leak to. But these pages are already indexed in Google SERPs. I don’t have any problem with their indexing but I want to change their snippets…i.e. title and description in SERPs. For the same I changed the title tag and Meta description of these previously indexed pages. But don’t know whether because of ‘nofollow’ or what…even after a week Google is still displaying the same snippets for these pages.

So I want to ask the webmasters that whether “nofollow” causes ‘no updates’ or ‘no crawling’ in SERPs for previously indexed pages…if yes, then how could I change their snippets…if no the should I just wait or should I simply get those pages removed from Google index using webmaster tools?
