Tom,

Thats like asking how long a piece of string is buddy.

There are just so many variables, including the niche, type of tour, source of traffic, whether its part of an affiliate programs offering, etc, etc...

I know some sponsors that havent changed their top converting paysites in years likewise, i know some sponsors that are always changing their paysite tours because of over-exposure lending itself towards lower conversions.

Regards,

Lee
