Was just mooching through the webmaster tools (I know, I must get a life) for one of the websites I look after and came across the option 'Index Status'

Now, it may have been around for a while and I've just never noticed it - or could be new; either way, this is a rare thing in WMT for me - some useful info and thought I would share the fact it is there with you since it may well help with several of the questions that show up periodically.

The help pages in WMT give more info:

It basically gives you a nice breakdown of the number of URLs indexed, including historic numbers, ignored for duplicate content, not indexed due to 'noindex' tags etc etc (this is separate to the 'sitemaps' option that was always there.
