I've noticed a very steady decline of page loss over the last few months on Google's index.
At the start of the year we had 5.8 million pages index. Now we are at about 4.3 million. Sometimes there are 200K pages lost on Google's Index (per webmaster tools) in a week.
However, I looked at our stats and our traffic is up from last year and day to day we are getting more or equal the amount of organic search engine traffic from Google, so no loss there. We still have good keywork rankings.
Because we have a large forum with over 16 million posts and 500K threads, I had a ton of messages on WMT for "duplicate meta descriptions and "duplicate title tags." Because of how Vbulletin works, it likely overpopulated my site with millions of pages from our forum - so I brought in an SEO/Coder to make sure the titles tags and meta descriptions - especially of forum threads with multi-pages were not identical to each other. I also made use of canonical links because there were VBulletin flaws were certain pages had more than one URL pointing to it.
I believe between those fixes and likely some Google updates, it cleaned out a lot of unnecessary pages.
Just wondering if anyone with a massive amount of indexed pages has gone through this before?
I did see that a year back the same thing happened and then a two weeks span 2 million pages were added to index.
Just hoping this is something I don't have to worry about.
