# What are the red flags when hiring an app marketing agency? *If they hide the numbers or own the accounts, walk away.* > The red flags when hiring an app marketing agency: guarantees, install-only reports, % of spend pricing, agency-owned accounts, fake reviews, and lock-ins. Source: https://www.appgrowthmarketer.com/hiring/app-marketing-agency-red-flags Author: Ar.Bhavesh Panse, AI App Growth Marketer (https://www.arbhaveshpanse.com) Published: 2026-10-02 ยท Updated: 2026-10-02 the red flags when hiring an app marketing agency are promises they cannot control, reports that hide what matters, and terms that lock you in early. watch for guaranteed rankings or installs, install-only reporting, agency-owned ad accounts, uncapped percentage-of-spend fees, long contracts, fake reviews or incentivized installs, and no named results. two or three together, walk away. this page goes deeper on each flag than the short list in my guide to [choosing a mobile app marketing agency](https://www.appgrowthmarketer.com/hiring/mobile-app-marketing-agency), and gives you the question to ask instead. ## Red flags in the pitch the pitch is where agencies make promises, so the red flags here are promises nobody can keep: guaranteed outcomes, one channel sold as the answer to everything, and case studies with no names or numbers. a good pitch asks more about your retention and users than it talks about the agency itself. ### 1. Guaranteed rankings or installs nobody controls the App Store or Google Play rankings, and no honest agency can promise a fixed number of installs at a fixed price before testing. guarantees usually mean they plan to hit the number with cheap, low-quality traffic. **what to ask instead:** "what result would you expect in eight weeks, what is it based on, and what would make you tell me to stop?" ### 2. One channel for everything if the agency recommends the same channel no matter what your app is, you are hearing their capability, not your plan. a meditation app and a B2B scanner app should not get the same pitch. **what to ask instead:** "which channel would you not use for my app, and why?" ### 3. No named case study with numbers a line like "we grew a fintech app 300%", with no name, no time frame and no metric is a story, not proof. ask which metric, from what base, over how long, and whether you can speak to that client. **what to ask instead:** "show me one case from an app like mine, with the app named, the metric, the time frame, and a reference i can call." ## Red flags in pricing and contracts pricing red flags are terms that pay the agency more when you spend more, regardless of results, or that lock you in before they have proved anything. the fee model shapes behaviour. if the agency earns more by raising spend, expect advice to raise spend, so read every term with that incentive in mind. ### 4. Percentage of spend with no cap a percentage of ad spend with no cap rewards spending, not efficient growth. it is common, so it is not a deal breaker alone, but uncapped it quietly pushes budgets up. **what to ask instead:** "can we cap the fee, or tie part of it to cost per retained user?" ### 5. Long lock-ins before results a six or twelve month contract signed before a single campaign runs puts all the risk on you. agencies that are confident in their work offer a short trial. **what to ask instead:** "can we start with a four to eight week paid trial and a thirty day notice period after that?" ### 6. Refusing a paid trial a trial is how you test their thinking and communication, not only results. an agency that will only start with a long retainer is telling you it does not expect to win on a short test. **what to ask instead:** "what would a paid trial look like, with one success metric we agree in writing first?" ## Red flags in the work red flags in the work show up after you sign: the senior team disappears, there is no creative testing process, your accounts sit in their name, and installs come from sources that break platform rules. these do the most damage because they hide inside reports that look healthy for months while the real users never arrive. ### 7. No access to your own ad accounts when ad accounts, analytics or creative files are created under the agency's business, you lose your data and pixel history when you leave. having managed up to $300k a month in ad spend, this is the first thing i check in any setup. **what to ask instead:** "will every account be created in my company's name, with me as admin, before any spend?" ### 8. Junior team after a senior pitch the founder or head of growth pitches, then a junior account manager runs your account. that is not wrong in itself, but you should know before you sign. **what to ask instead:** "who exactly works on my account each week, how senior are they, and can i meet them before signing?" ### 9. No creative testing process on Meta and TikTok the creative does most of the targeting, so an agency without a weekly testing loop is mostly adjusting bids. ask for their last month's test log, anonymised. the process i expect is in [creative testing for apps](https://www.appgrowthmarketer.com/paid/app-creative-testing). **what to ask instead:** "how many new concepts, not edits, will you test per month, and what is your kill rule?" ### 10. Fake reviews or incentivized ratings any offer to boost ratings with bought, incentivized or fake reviews puts your whole developer account at risk. Apple's [App Review Guidelines](https://developer.apple.com/app-store/review/guidelines/) say manipulating reviews can lead to expulsion from the developer program. **what to ask instead:** "how do you grow ratings? i expect in-app prompts to real users and nothing paid or incentivized." ### 11. Bot or incentivized installs installs from bots, click farms or reward walls look great on a dashboard and never retain. Google Play's [ratings, reviews and installs policy](https://support.google.com/googleplay/android-developer/answer/9898684?hl=en) bans inflating installs by illegitimate means, and Apple's guidelines warn against using third-party services to inflate chart rankings. **what to ask instead:** "list every traffic source you will use, and show me day 7 retention by source." ## Red flags in reporting reporting red flags are reports built to look good rather than to help you decide. the main one is counting installs, clicks and impressions while leaving out retention and cost per retained user. a good report tells you what to stop, not only what went up, and it uses numbers you can check in your own accounts. ### 12. Reporting installs, not retained users an install report says what you bought. a retention report says whether it was worth it. if every slide is installs, CPI and impressions, you cannot tell good spend from bad. the difference is laid out in [CPI vs CAC](https://www.appgrowthmarketer.com/learn/cpi-vs-cac). **what to ask instead:** "can every weekly report show cost per retained user and blended CAC, pulled from my own analytics?" a short checklist to send before any call: > before we talk, please confirm in writing: 1) all accounts in our name with us as admin, 2) a named team and their seniority, 3) one named case with metric and time frame, 4) fee model with any cap, 5) a 4 to 8 week paid trial option, 6) traffic sources you will and will not use, 7) a sample weekly report. if an agency passes all of this and you still are not sure an agency is the right shape, compare it with one operator in [app growth marketer vs agency](https://www.appgrowthmarketer.com/hiring/app-growth-marketer-vs-agency), read [how to hire an app growth marketer](https://www.appgrowthmarketer.com/hiring/how-to-hire-app-growth-marketer), or see what working with me looks like on the [hire](https://www.appgrowthmarketer.com/hire) page. ## Frequently asked questions ### What is the biggest red flag in an app marketing agency? the agency owning your ad accounts, analytics or creative files. everything else can be fixed with a better brief or a new contract, but if they own the accounts you lose your data, your learnings and your pixel history the day you leave. insist on admin access in your own name before any spend. ### Is percentage of ad spend pricing always bad? no. it is common and can be fair at scale. the problem is when it has no cap and no link to results, because the agency then earns more by spending more, whether the extra users stay or not. ask for a cap, a floor, or part of the fee tied to cost per retained user. ### How long should an app marketing agency contract be? start with a paid trial of four to eight weeks and a short notice period after it, often thirty days. a long lock-in before any results shifts all the risk to you. good agencies are confident you will stay because the numbers are good, not because the contract says so.
