A rewarded survey asks the user to answer questions in exchange for currency. Because the action is small and finishes in minutes, surveys fill the low-commitment end of an offerwall, giving users who will not install an app or make a purchase something worth doing.

How it works

A research panel supplies questionnaires with a target respondent profile. The user selects the survey, answers a short set of qualifying questions, and if they match the profile they complete the full survey and are rewarded. The research buyer gets responses from a real, identifiable audience segment, and the publisher earns a payout for each completion.

Screening and its costs

Most surveys begin by screening, and users who do not fit the target are cut partway through. Handled badly this is the worst experience on a wall: real effort spent, nothing earned, no explanation. Good implementations pay a small consolation amount for a screen-out, which keeps users willing to try the next one. The economics support it, because a screen-out costs the publisher very little and a user who stops opening the wall costs a great deal.

Why publishers run them

• They monetize users who will never install anything. The majority of any audience falls into this group.

• They settle fast. Survey completions carry little chargeback or return exposure, so they rarely need a long hold period.

• They refresh constantly. New questionnaires arrive daily, so the wall does not go stale for frequent users.

• They balance the offer mix. Purchase offers pay far more but convert rarely; surveys supply steady everyday volume.

Surveys vs. other offer types

Surveys occupy a specific position in the offer mix that nothing else fills. Purchase offers pay many times more and convert rarely; engagement offers sit in between and take days. Surveys pay little, convert often, complete in minutes, and settle almost immediately. That makes them the reliable everyday floor of a wall's earnings and the entry point for users who have never completed anything. A wall without them tends to have a converter base far smaller than its engaged audience.

Common mistakes to avoid

• Not paying for screen-outs. It is the single biggest driver of complaints about survey inventory.

• Overstating the reward before qualification. Show what a screen-out pays as well as what a completion pays.

• Hiding the time required. A survey advertised as quick that takes twenty minutes converts once and never again.

• Filling the wall with surveys alone. They anchor the low end; the high end still needs engagement and purchase offers.
