Just make yourself a personal checklist on sites you plan to promote. Get in the members area and review it - if you dont like it...chances are you wont sell it well and joe surfer wont like it either.
Does site XYZ update often?
How do I rate their content?
Would I renew my membership?
Is the monthly cost a value for product recieved?
Just ask yourself common sense questions as if you were purchasing the membership for yourself.
