Remember that PageRank is a pretty meaningless and irrelevant measure. All PR looks at is your inbound links. If you haven’t got lots of them, your PR will stay very low.
That doesn’t mean you can’t get a good position in the search results though - and that is what really matters, that’s what you should be focusing on.
This may sound rude, but 40,000 pages of what exactly? I work on huge, authoritative content sites that have less pages than that! A description of your site and what it does would be very helpful.
Actually from last year Google has updated PR very few time and may be your website not updated yet.But I ll recommend you to do quality link building with high PR,do follow and relevant website.You can also do some work on website content too.
Thanks!
