I'd say Google Analytics is pretty good at figuring these things out, so keep an eye on that. If you see anything strange there, that's a good time that you look more into that.
I must be missing some technical stuff for sure (I guess smarter guys would say that you probably need to do something about those bots to save on your bandwidth, etc.) but I personally only pay attention to Google Analytics reporting never bothering with checking my cookie data and I've got along just fine so far...
Everything will be ok in the end
If it's not ok, it's not the end
