App store optimization (ASO) has traditionally focused on getting an app found and installed: metadata, keywords, screenshots, and the other factors that shape discovery and conversion. But the picture does not end at the download. Ratings, reviews, and engagement continue to reflect what users experience after installation, and each can be influenced by something ASO strategies rarely account for: the ads running inside the app.
For users, the line between the app and the advertising inside it is not always clear. A disruptive interstitial, an unexpected redirect, or a deceptive ad may have originated with an advertiser, ad network, or demand source, but the user encounters it as part of the app experience. The consequences can then extend back to the app store, shaping how the app is rated, reviewed, and ultimately perceived by current and prospective users.
Ad Quality and the Signals Behind App Store Ranking
Ratings and reviews do more than reflect how users feel about an app. Apple states that both can influence App Store search ranking, alongside factors such as text relevance and user behavior. Google Play similarly considers ratings, reviews, and engagement when evaluating apps for discovery, and goes further by identifying a “good ads experience inside the app” as an indicator of app quality.
Neither store claims to detect a bad ad and penalize an app directly. What matters is what happens after: whether users keep engaging, what they rate the app, and what they write in a review. AppHarbr’s research among mobile game players shows one example of how ad quality can reach those signals: 37% of surveyed players said they had left a negative review specifically because of ad-quality issues. The bad ad itself may not be a ranking factor, but the user response it generates can become part of the signals the stores consider.
Bad Ads Turn an Install Into an Uninstall
A negative review is only one possible response to a disruptive ad. In AppHarbr’s October 2024 survey of mobile game players, 58% said they quit a session immediately after encountering one. The consequences can build with repeated exposure: 84% of respondents had uninstalled a game after a disruptive ad experience, and most did so after encountering the problem more than once rather than immediately.
The impact can extend beyond the user who leaves. In the same survey, 61% said a bad ad experience had led them to discourage others from downloading the game. For publishers, these responses make the cost of poor ad quality broader than ASO alone: shorter sessions mean fewer opportunities to generate ad revenue, and an uninstall removes future sessions altogether. At scale, those behaviors can surface across retention, LTV, ARPDAU, and other monetization metrics.
How Bad Ads Disrupt and Deceive
Poor ad quality does not have a single shape. An ad can trap a user inside it, push them out of the app they opened, or mislead them with deceptive content. Each interferes with the post-install experience differently, and none is limited to a particular app category.
One example is dismissibility. When a close button is fake, hidden, or missing, a user trying to return to the app can instead find themselves trapped inside the ad. In AppHarbr’s October 2024 survey of mobile game players, 93% said they abandon gameplay when deceptive close buttons prevent them from exiting. The figure is specific to games, but it demonstrates how an ad can directly obstruct the experience a user was trying to continue.
Unexpected redirects create a different interruption. An ad can push a user out of the app and into a browser, app store listing, or another destination without the user intending to leave. Instead of simply occupying space within the app, the ad interrupts the session by taking the user somewhere else.
Other deceptive ads create problems through their content rather than their behavior. Fake celebrity stories, false prize claims such as “you won an iPhone,” or ads designed to resemble legitimate content can mislead users even when the ad itself is easy to close. In these cases, the problem is not whether the user can exit the ad, but what the ad leads them to believe.
For ASO, these experiences matter even when they never produce an uninstall or negative review. Google Play considers engagement when evaluating apps for discovery, and an ad that interrupts a session, redirects a user elsewhere, or prevents them from returning to the app can work against continued engagement. That does not mean Google identifies the ad as the cause or treats bad ads themselves as a ranking signal. But ad quality can shape the user behavior behind the signals Google considers. Some of these behaviors can also create a more direct problem with the app stores themselves.
When Bad Ad Experiences Become App Store Policy Problems
Google Play treats ads and their associated offers as part of the app itself, making developers responsible for the advertising experience served inside it. Its policies require ads that interfere with normal use to be easily dismissible without penalty, treat ads with no clear way to close them as a common example of a violation, and require interruptive full-screen interstitials to become closeable within 15 seconds, with exceptions for certain opt-in and rewarded formats. Google Play also restricts disruptive and deceptive behavior that interferes with how users interact with an app.
Apple takes a less prescriptive approach to timing but draws a similar line around user control. Under Guideline 2.5.18 of its App Store Review Guidelines, interstitial or interruptive ads must be clearly identifiable as advertising, cannot manipulate or trick users into tapping, and must provide a visible, easily accessible close or skip control. Apps containing ads must also give users a way to report ads that are inappropriate or do not match the app’s age rating.
An irrelevant or irritating ad may frustrate users without violating either store’s rules. Ads that deceive users, unexpectedly interfere with normal app use, or prevent them from exiting carry a different risk. In those cases, an ad-quality problem can become both a user-experience issue and a policy problem for the app in which it appears.
Protect Ad Quality Before It Reaches the User
By the time a bad ad appears in a complaint, an app-store review, or an uninstall, the user has already experienced it. Reactive monitoring can help publishers identify the creative and escalate it to the responsible network, but it cannot undo the session that was interrupted or stop the same ad from reaching other users while the issue is being investigated.
Protecting ASO from ad-quality problems starts earlier in the ad lifecycle. AppHarbr detects and blocks unwanted, deceptive, and disruptive creatives before they render in the app. Publishers using AppHarbr have seen bad ad reviews in app stores decrease by 80%.
For ASO, that means protecting the experience that follows the install, not only optimizing the path that leads to it. Request a demo to see how AppHarbr can help protect that experience before a bad ad reaches the user.
