CPA conversions

I am listing a product on clickbank.

I think most of the cpa experienced poeple on this forum are affiliates.
Do you think a 30 day free trial is attractive for affiliates? (Along with a recurring commission)

In my mind:
The consumer is attracted to the 30 day free trial - higher conversion rate
The affiliate is interested in the recurring commission - 50% monthly

Downside:
The affiliate doesn't get paid for first 30 days at least since that is free for the customer

Hoping to hear from some people with good experience either as affiliate or advertiser.

Hey there, tuns out Clickbank policy is 60-day refund for customers as far as I know. Hope I'm understanding you correctly, not sure why this would benefit the affiliate, or generate more sales as there is already that 60-day guarantee..? anyways hope someone who has more experience as vendor can chime in.. Good Luck!
