Our sellers provide visitors and unfortunately cannot guarantee any results. It all depends on your offer, how attractive it is to the potential customer, what benefits you offer to your audience etc.
We would recommend you to run a few test orders with different sellers and see which seller can provide good results for your offer.
Sales also are very dependent on your email follow-up sequences on your autoresponders and not many visitors would subscribe/buy your product immediately after seeing your advertisement. Normally it would take 3-5 exposures to the ad before getting a sale.
