You Are Paying for Views. But Views Are Not Memory.

You are paying for your ad to be seen.

But being seen is not the same as being remembered.

That is the uncomfortable truth behind a 2025 eye-tracking study that every brand advertising inside mobile apps should read.

The Study

Researchers from Eskisehir Technical University tracked the eye movements of 79 participants while they actively played a mobile sports game for ten minutes. Every ad placement inside the game was mapped as an Area of Interest. After the game, participants were asked what they remembered.

The question the researchers wanted to answer: does looking at an ad longer mean you remember it better?

The answer was no.

What Actually Drives Recall

The strongest predictor of brand recall was not how long someone looked at the ad. It was where the ad was placed within the game environment.

Brands integrated into task-relevant zones — meaning areas central to the gameplay itself, like the net area in a tennis game — achieved significantly higher recall compared to ads placed in peripheral positions. Even when participants spent more total time looking at a peripheral ad, they remembered the centrally placed brand better.

The researchers call this task-integration. When your ad sits inside the zone where the player's attention is naturally focused by the game mechanics, it gets encoded into memory more effectively. When it sits on the edge of the screen, it gets seen but not retained.

Why This Matters

The mobile gaming ad market is enormous. Brands spend billions placing ads inside apps assuming that visibility equals impact.

This study says otherwise.

You can have a high dwell time on a peripheral banner and still lose to a smaller ad placed in the right spot. The brain is not a passive recorder. It encodes what is relevant to the task at hand. Everything else, even if technically in the field of view, gets filtered.

This also explains why so many in-app advertising campaigns underperform despite strong impression numbers. Impressions measure exposure. They do not measure cognitive load, task context, or memory encoding. Eye tracking does.

The Broader Lesson

This finding goes beyond mobile games.

Any environment where your audience is cognitively engaged in a task — whether that is scrolling a feed, navigating a website, or walking through a supermarket — creates a hierarchy of attention. Some zones are task-relevant. Others are peripheral. And the same ad placed in different positions within that environment will produce radically different results.

The only way to know which zones are actually doing the work is to track where eyes go, how long they stay, and what gets remembered afterward.

Not what users say they noticed. What the data shows.

The Practical Takeaway

Before you optimize your creative, optimize your placement. Before you increase your ad spend, understand the attention architecture of the environment you are advertising in.

And if you want to test whether your current placements are sitting in the right zone or the peripheral blind spot, eye tracking will tell you in days, not months.

This is exactly what we built RealEye for. No lab, no expensive hardware, no waiting. You upload your stimulus, your participants join from wherever they are, and you get heatmaps, gaze paths, and fixation data showing you which zones are actually doing the work. If you have never tested your ad placements with eye tracking, there is a free 7-day trial at realeye.io worth taking before your next campaign goes live.

What is your experience with in-app advertising performance? Do your impression numbers match your actual recall results? We would love to hear from people running campaigns in gaming or app environments.
