When spending time clicking and clicking, you want to be sure you are surfing the exchanges that have the best possible results for your ads.
In order to maximize your number of credits, it may be best to use some sort of downline builder for the exchanges that you surf. Ahh..but which downline builders are best? There truly is SO much out there these days, that the task of finding the best sources can be time consuming and frustrating.
I prefer to use those that have been tested and proven to give the best results.
For this, I trust Traffic Hoopla. All of the traffic exchanges in their list are independently tested and statistically proven as best for traffic delivery and results. Of course the ultimate goal is to join those exchanges in the list, then promote your own Hoopla page, thereby building your downline in all of the exchanges listed. However, you may just want to use Hoopla to stay updated with the current top-ranked advertising resources. There is also a list of Safelists that gave the best results in the tests.
Another source to consider is Affiliate Funnel. You will find there a list of exchanges that are voted on daily by the surfers themselves.
I hope these lists will help you find the most useful exchanges online and build a lot of credits for you too. :)
