Google's Metrics Are Chimeras

Google provides some brilliant tool for free to those of use building businesses on the web.

Indeed, it could be argued that a $100bn of business is now dependent on their technology.

However, it seems to be very inconsistent.

I can move between the Google silos - Adsense, Blogger, Analytics and Adwords and I get totally different metrics. This evening I've seen variations of +/- 1000% on this website using Google tools.

And unlike most online services, google really, really don't want to engage with you on their problems. It's their way of the highway. Trouble is it could be a dirt track or a seven lane highway. No one else knows...

I have no idea why and I'm not going to cast theories that could get me sued, but this seem sinister to me. Why has no one else highlighted this ?
