Way has the number of pages crawled plummeted?

Why has the number of pages crawled for our campaign plummeted in Moz Analytics – down to 729 from over 10k? Don't see any issues in Google Analytics with crawling our site.

How many pages does your site have? Did you possibly clear up a bunch of parameters and duplicate content, so the crawl is more accurate?

Eyeglasses,

I wonder if your Mozrank or Moztrust has ratcheted down, as well, or if you've made any architectural/navigational changes to the site. With that many pages, it is possible that its not getting crawled as deeply as it had in the past if those dropped pages no longer met the value criteria for crawling by rogerbot--maybe you lost a good link or two or something like that.  Also, if you changed any internal linking, it might be that those pages may have been pushed down in the architecture and not be as accessible as they once were.

Chris, what you're talking about is Open Site Explorer. I believe what Eyeglass Guy is talking about is the campaign crawl, which is an entirely separate crawl system.

[Chris.Menke]

Ah huh, I see. So does the campaign crawler have a different name or does it go by Rogerbot too?

[KeriMorgret]

Rogerbot is the campaign crawler, and OSE has a different name. I know it can be a tad bit confusing at times.

Wow, that was like an hour of digging--trying  to track down the linkscape crawler.  I think I've got it now.
