Interesting from The Big G today.
Lately Google's site: page count had been on a roller coaster of +/- 10% every day. Then it went to +/- 15% every few days. Then is went to 3 different numbers throughout the day. (All still indicating well indexed.)
Now, today, they've sent a visitor to a page in a section of the site they show 0 results for when doing a site:example.com/dir search. (It usually works the opposite way, meaning I can find a page using a site: search before I can find it in the results or as the landing page for a query.)
Definitely leads me to believe there almost have to be at least 2 or more distinct datasets out there right now to see those types of fluctuations in numbers for anything. *
* Unless maybe someone's been bored and using their 20% time and breaks to update the site: page estimating system, then revert it a while later just to mess with us, which I guess is a possibility, but that still doesn't account for how they referred a visitor to a page they don't have indexed according to a site: search.
