Isn't it weired?  I've been noticing some of my different sites having better google page index rankings on the weekends.  Regardless of how much content we keep updating or refreshing it never fails to have minimal indexing results.  During the week indexing stay at reasonable fluctuation based on uploaded content.  Come Friday, Saturday and Sunday until evening time (PST) my page indexing are at it's maximum.  Once twilight hours of Monday morning roll around our controversial sites seem at minimum?  Is anyone else noticing this? Can you explain the volatility and why?  Of course algorithms do shift like pendulum but do take notice of your own sites indexing count by typing in google search engine site:www.value.com
