An offerwall is an in-app or on-site screen that presents a list of tasks a user can complete — install an app and reach a level, sign up for a service, watch videos, answer a survey, make a purchase — in exchange for a reward such as in-game currency, loyalty points or account credit.
Definition
An offerwall is an in-app or on-site screen that presents a list of tasks a user can complete — install an app and reach a level, sign up for a service, watch videos, answer a survey, make a purchase — in exchange for a reward such as in-game currency, loyalty points or account credit. The publisher (often a free-to-play game or a rewards app) is paid by advertisers for each completed action, and shares part of that with the user as the reward.
Offerwalls are a monetisation tool for the publisher and an incentive-traffic source for advertisers. The user's motivation is the reward, not the advertised product, so offerwall traffic is by definition incentivised: the conversions are technically real but the users have no intent toward the offer and rarely engage after collecting the reward.
In context
For iGaming, offerwall traffic is almost always the wrong fit. Operators reject incentivised registrations and deposits because a user who signed up to unlock game currency has no intent to play, deposits the minimum if at all, and never retains, so an operator paying CPA on offerwall traffic is paying for nothing.
Offer terms explicitly prohibit incentive traffic, and cohort analysis exposes it quickly — near-zero day-7 retention, deposits at the qualifying minimum followed by withdrawal.
The risk for a legitimate affiliate is unknowingly buying offerwall traffic through a sub-source in a chain — a cheap install package or an "engagement" reseller that is really an offerwall placement — and having the conversions clawed back. Defences are the standard ones for incentive traffic: demand SubID transparency into sub-sources, run new sources at a capped budget until a cohort matures, judge on cost per retained or depositing user, and cut anything whose users collect the conversion and never come back.
Offerwalls have a legitimate place in casual-game and app-install user acquisition where the advertiser knowingly accepts incentivised users at a price that reflects their value; they do not have one in real-money iGaming acquisition.
Worked example
An affiliate buys a cheap install package that turns out to route through an offerwall. The resulting casino cohort has 0.5% day-7 retention and deposits clustered at the $10 minimum with immediate withdrawal requests.
The operator claws back the conversions, and the affiliate removes the sub-source and adds an incentive-traffic check to its source vetting.
