This may have been posted before, so apologies if it's a repeat. I have two sites I use AdSense on. One is 6 years old, and gets around 100,000 impressions a day. The other is less than 2 months old, and gets around 6,000 impressions a day. I heard somewhere that Google doesn't like you having multiple accounts, so I used the same AdSense account for both. The topic areas for the sites are completely different - one is Financial (and I guess higher value), the other is Entertainment. Is there a chance the Entertainment site could drag down the value of the ads on the Finance site - and if so, how do I get round this? My earnings on the larger site are still pretty good, but I'm worried that maybe it could be better.
