Tools that crawl 2 million page sites

[ilhaam]

Our site is about 2million pages deep, 50% of which is stale content. Yes, I know - OMG #unhygienic. Even if we get approval to get rid of half of it. SEOMoz Pro Elite only crawls 20k deep - what can i do to crawl and diagnose the whole site. Are there any tools anyone can suggest. SEOMoz??

There is an enterprise version of SEOmoz which will do 1 million pages a month and up to 30k keywords which is well worth looking into if you have a enormous web property.

That's good to know. It sounds like that's probably the best way. I also use Screaming Frog (http://www.screamingfrog.co.uk/seo-spider/) to try and crawl sites and with dedicated 2Gigs of ram, it's able to crawl around 50k pages. If your site is structured in sub-folders, you might be able to break it into parts and then crawl. But then if not, the SEOMOZ Enterprise looks like the way to go.
