Test Competing Merchants

Do not become married to a specific affiliate program even if it has performed well for you in the past.

Always tests your options and always see if you can find a competing merchant that performs better for your affiliate marketing efforts. This does not mean you have to change all of your campaigns over to a new merchant. Just change a single adgroup or even a single ad within an adgroup and direct traffic to the new merchant.

If you find it converts better switch another ad or adgroup over and see if the conversion rate holds. If sales improve them you can make the switch, if not, you have learned a lesson and you know one more thing that does not work than you did before and become a better more informed affiliate marketer in the process!
