An opt-in ad experience begins with the user's decision. Nobody is interrupted mid-session; a user opens an offerwall because they want currency and picks the offer they are willing to complete. Attention is granted rather than taken, and almost everything distinctive about rewarded performance follows from that one difference.

How it works

The publisher places an entry point somewhere the user will look for it, usually a store or rewards menu. Nothing is served until the user taps it. Inside, the user browses offers, sees what each one requires and pays, and chooses. At every step the user can leave without having lost anything.

Why it matters

Self-selection has already filtered for intent by the time an offer is tapped, which is why conversion rates on rewarded inventory sit far above interruptive formats and why its eCPM tends to sit at the top of a publisher's stack. It also sidesteps most of what drives ad-blocker installs and one-star reviews, since the user cannot be annoyed by an ad they went looking for.

Opt-in vs. forced ad views

A forced interstitial interrupts a session to extract an impression, and the user's only options are to wait it out or leave. An opt-in placement waits to be opened. The commercial consequence is that interruptive formats have to be rationed with frequency capping to avoid fatigue, while an opt-in placement can be permanently available without wearing anyone down.

What the format demands in return

The bargain only holds if the reward arrives as promised. This is where opt-in stops being a placement type and becomes an obligation:

• State the requirement plainly. A user who thought they had finished, and had not, feels cheated whether or not the terms were technically accurate.

• Show pending state. A pending reward with a clear release date reads as process; silent currency reads as theft.

• Explain reversals. When a reversal removes a reward, an unexplained deduction costs more trust than the reward was worth.

• Honour the amount shown. Nothing kills a wall faster than a payout that differs from the one advertised.

Where opt-in placements fit

Opt-in inventory works best where a user already has a reason to want currency, which is why it is standard in games with an economy and increasingly common in any app with credits, points, or entries. It is a poor fit where there is nothing to spend a reward on, since a reward with no sink is just a number. The entry point matters as much as the format: a wall users cannot find produces no engagement regardless of how good the offers behind it are.

Common misconceptions

• Opt-in does not mean low intent. Users who choose an offer complete it at rates cold traffic never reaches.

• It is not only for games. Any app with a currency, credit, or reward system can run an opt-in placement.

• Opt-in is not a consent checkbox. It describes a user choosing to engage with a format, not a privacy permission.
