muliple aff programs, same niche, how do you do it?

[andyem]

Many affiliate companies offer multiple affiliate offers in the same niche and being new to the game I am wondering how others go about promotiong more then 1?

Do you split the keywords in two lists and half go to one half go to the other?
I know Adwords and Adcenter dont allow you to bid twice on the same keywords so I cant run them all on the same keywords.
Should I run one adcenter one on adwords?

Anyone have any ideas?

run one with all keywords then the other and compare results
