I have noticed a repeated pattern with Google since about May of this year...and now it's happened so many times that it's definitely a pattern. Every 3-4 weeks or so I notice that the number of pages Google has indexed for my site skyrockets for a few days, peaks, and then drops back down to where it was. This has happened every 3-4 weeks for months now. I am checking my site using site:http://examplesite.com/*. If I drop the asterisk the page number is much higher, but I assume those are all in the supplemental index. Has anyone else noticed this pattern? Thanks
