Banners from competitors in affiliate program

[Clodo]

What is the effect of serving banners from advertisers in an affiliate program who compete against each other? Like Comcast and Verizon or Computer Associates and Trend Micro.

I mean not both in the same page at the same time but alternating in a random manner. The visitors are loyal and will sure see both much more than once.

Will it confuse potencial buyers and prevent sales? Or is it one more option to the consumer leading to increase in overall sales?

The best way to find out is test it.

As for my guess, in some cases I would say definately better to show competitor's affiliate programs. The reason why is because sometimes a target market still responds differently to different brands, content, and sales pages.
