What is a traffic exchange?
Well, according to powersurfcentral: A traffic exchange is a membership site where all members can surf and view other members sites. This is done based on a system of credits where 1 credit is equal to one random member of the site to visit your page for a set amount of seconds.
Some sites seem to change the timer or number of seconds you have to view a page once in a while and it can be very confusing when the timer keeps changing.
Also, you can usually purchase "upgrades" where you get a lower surf timer and then you can surf more with the time you have to surf for credits.
Then there is also the problem of credits per click. Some sites do not give 1:1 meaning you have to surf more if it is 2:1 (.5 credits per click) or 3:1 (.33 or .34 credits per click) surf ratio, this also makes it confusing to figure out the best sites to surf to get the most credits for your time.
And I forgot to mention progressive surf ratio ... maybe I shouldn't but the credits per click changes (usually goes up) while you surf. That is a good thing.
