Most of my client traffic is the same, my own sites are up, but they're seasonal and probably would be up anyway. I can't compare month to month and have it make sense, but month to corresponding month last year - I'm about double. I put a heavy emphasis on social sharing AND mobile optimizaiton over the past 18 mos, and it's paying off. My mobile traffic is WAY up.
skweb, if I were in your position with your five sites, I'd start thinking of ways to diversify. If you were able to pull down that much in AdSense, even Pandalized you're probably getting pretty good traffic. I'd be thinking of ways I could branch off into email, for one thing.
