Best idea is to count everything, and send all traffic as normal. So leave everything default.
Much much later, if your site has big traffic, its good idea to try to trap nocookie so send nocookie to gallery in table of spec. out settings. Nocookie out traffic is completely useless because remote script wont give you credit for it - because it cannot track it, however it will decrease the quality of your out traffic.
However filtering your traffic too much - especially when your site is still small - will prevent growth.
This is because remote trade scripts do give you credit for bot traffic as well ... crazy but true.
So basically the bigger is your site, the more you can afford to filter your out traffic.
