I know for obvious reasons it is, such as knowing which pages/posts are generating what kind of revenue and what their ctr and cpc are.

BUT...

Does anyone here who's been around for a while do this or avoid it at all costs in the case that Google knows to much about how you get your traffic?

Just curious as I am averaging over $300 a day in Adsense and want to keep that coming, if you know what I mean

Thanks in advance
