What Questions Should I Ask a Mobile Fraud Detection Vendor Before Buying?

Before you buy mobile fraud detection, ask about detection methodologies, false positive rates, integration time, real-time blocking, network coverage, pricing model, and refund recovery support. These seven areas separate tools that actually protect mobile budgets from those that just generate reports.

Why These Questions Matter

Mobile ad fraud quietly drains budgets. Bot clicks, click injection, and SDK spoofing inflate your costs and ruin your conversion data. A good vendor stops the bleeding; a bad one adds a dashboard and a monthly fee.

Asking the right questions upfront is cheaper than discovering a mistake after you've signed a contract. You need a vendor that fits your ad spend, your channels, and your team's ability to act.

Detection Methodology: What Does the Vendor Actually Look For?

Not all detection is equal. Some vendors rely on IP blacklists and simple rules. Others use behavioral analysis that mimics how real humans move and click.

Ask these questions:

• What signals does your detection use? (IP, device, behavioral, network)
• Do you use real-time session telemetry or post-hoc analysis?
• How many independent checks does the system run per session?
• How do you handle residential proxies and device farms?

For example, one vendor claims to run 106 independent checks per session, including ghost clicks, honeypot traps, and mouse tremor analysis. That breadth matters because sophisticated fraud mimics human behavior.

False Positives and Accuracy: How Often Will the Vendor Cry Wolf?

A vendor that flags everything is useless. False positives block real customers and hurt your campaign performance. Ask:

• What is your false positive rate?
• How do you separate a real user from a bot when signals conflict?
• Do you cross-check signals or rely on a single trigger?
• Can you show me examples of false positives and how you corrected them?

Accuracy claims should be backed by methodology. One vendor states 99% accuracy based on corroboration across many signals, not a single browser tell. Ask for the same logic from any candidate.

Integration and Setup: How Fast Can You Start Protecting Your Campaigns?

Time-to-value matters. If setup takes weeks, you'll keep losing money in the meantime. Ask:

• How long does implementation take? (Typically under an hour?)
• Do I need to change my SDK or add a tag? What's involved?
• Do you work with my MMP (like Branch, AppsFlyer, or Adjust) or ad network?
• Is there a free trial or pilot period?

Some vendors claim a one-minute installation with no credit card required. While that's attractive, verify that the integration covers your full funnel, not just clicks.

Real-Time Blocking and Response: Can the Vendor Act Before the Damage Is Done?

Fraud is most costly when it slips through. Real-time blocking stops fraudulent clicks before they trigger spend. Ask:

• Do you block in real time or only flag after the fact?
• Can I set custom rules per campaign or network?
• How do you handle attacks that evolve during a campaign?
• What's your response time when a new fraud pattern appears?

Real-time behavioral telemetry can catch automation scripts instantly. But ensure that blocking doesn't interfere with legitimate traffic.

Network and Platform Coverage: Which Ad Channels Does the Vendor Protect?

Your mobile ads likely run on Google, Meta, and maybe Apple Search Ads or other networks. A vendor that only protects one channel leaves gaps. Ask:

• Which ad platforms do you support? (Google, Meta, TikTok, programmatic, etc.)
• Do you cover in-app placements, web, or both?
• How do you handle audience network and partner inventory?
• Can you protect both clicks and post-click events like installs and purchases?

Coverage should match where you spend. If a vendor only handles Google, you'll need another tool for Meta.

Pricing and Contract: What Does It Really Cost?

Pricing models vary: percentage of ad spend, fixed monthly fee, or per-click. Each suits different budgets. Ask:

• What is your pricing model? Is it a flat fee or a percentage of spend?
• Are there overage charges if I scale up?
• What's the contract length? Can I cancel monthly?
• What features are included in the base price?

Be wary of vendors that tie fees to a percentage of total spend—they might have a conflict of interest. A transparent fee based on services is often better.

Refund Recovery and Support: Can the Vendor Help You Get Your Money Back?

Fraud doesn't just waste spend; it steals it. Some vendors help you claim refunds from ad platforms like Google and Meta. Ask:

• Do you help with refund disputes? What's your approval rate?
• Do you provide audit-ready reports with video proof?
• How far back can refunds go? (Some vendors claim up to 2017)
• How do you prove a bot click vs. a human misclick?

A vendor that actively recovers money adds real ROI. For instance, one service states it recovers refunds from Google Ads dating back to 2017 and has a high refund approval rate across claims.

The Decision Rule: How to Score a Vendor

Create a simple scorecard. Rate each category from 1 to 5 based on your needs and the vendor's answers. Weight the categories that matter most for your business.

1. Detection methodology (30%): depth and coverage of signals.
2. False positive rate (20%): accuracy and safeguards.
3. Integration and setup (15%): time to deploy and complexity.
4. Real-time blocking (15%): speed and control.
5. Network coverage (10%): matches your channels.
6. Pricing model (5%): transparent and scalable.
7. Refund recovery (5%): ability to get money back.

Add up the weighted scores. Choose the vendor that scores highest, but only if it passes your non-negotiable thresholds (e.g., must support both Google and Meta).

Key Facts to Verify (Based on One Vendor's Claims)

The following claims come from BotRefund, a mobile fraud detection service. Use them as a benchmark when evaluating any vendor.

Claim	What It Means
106 independent checks per session	Broad coverage—looks at browser, network, device, and behavior signals.
99% accuracy	High confidence through cross-checking, not single triggers.
About one minute to add to website	Fast integration—minimal friction to start protecting.
Bot clicks steal up to 20% of Google and Meta ad budget	Shows potential waste—justifies the investment.
Refund recovery dating back to 2017	Ability to reclaim historical spend via disputes.
Refund Approval Rate (reported high)	Indicates effectiveness in getting money back, but verify actual numbers.

Limitations: When the Advice Doesn't Apply

These questions assume you have significant mobile ad spend (at least a few thousand dollars per month). For very small budgets, a free tool or basic MMP filtering may be enough.

Also, no vendor catches everything. If you run highly regulated campaigns or use unusual devices, expect some false positives. Always test with a pilot before committing to a long contract.

FAQ

What's the most important question to ask?

Detection methodology—because it determines whether the tool can actually catch modern fraud like click injection and AI-driven bots. Without solid detection, everything else is irrelevant.

How long does a mobile fraud detection implementation take?

It varies. Some vendors promise a one-minute tag installation, while others require SDK changes and server-side setup. Ask for a realistic timeline, including testing.

Can a vendor help me get refunds from Google or Meta?

Yes, many vendors provide audit reports and proof to support refund claims. Some even handle the negotiation. Ask about their approval rate and how far back they can go.

What pricing model should I expect?

Common models are a flat monthly fee, a percentage of ad spend, or per-click. A flat fee is easiest to budget. Avoid models that penalize you for scaling.

Do I need a vendor if I already use an MMP like AppsFlyer?

MMPs provide baseline filtering but often lack real-time blocking and advanced behavioral detection. A dedicated fraud vendor can fill the gaps. Ask your vendor how they integrate with your MMP.

How often should I re-evaluate my fraud vendor?

At least once a year. Fraud tactics change, and your ad spend may grow. Check that the vendor still meets your needs and that their detection rules are updated.
