Hi can anyone confirm is it true that if you have in one adsense account both low paying niches as well as the high paying niches that Google pays significantly less for high paying niches than it would pay if there were no low paying niches? Does bad ecpm on low paying niches degrades ecpm on high paying niches, or is the bottom line each site for itself so you'll get the same clicks regardless of all other niches you have in your account? What do you think?
