The Challenge

Budget disappearing with nothing to show for it

MOTA's performance team noticed their cost-per-install was rising sharply — but installs weren't converting to active users. Something was eating their budget.

Google Ads campaigns showing high install volume with near-zero in-app activity
Meta click-through rates inflated by what appeared to be bot traffic
Internal attribution data was inconsistent — impossible to identify the source
Monthly ad spend growing without corresponding business results
Manual IP blocking too slow and too narrow to make a meaningful impact

Why Spider AF

The only platform built specifically for ad fraud detection

MOTA needed more than a generic analytics tool. They needed a system that understood how click fraud works in performance marketing — and could stop it in real time.

Real-time invalid traffic detection

Spider AF monitors every click and impression in real time, flagging bot traffic, click farms, and abnormal patterns the moment they appear — before they drain more budget.

Direct Google & Meta integration

Native integrations with both platforms allow Spider AF to feed exclusion lists back automatically — no manual uploads, no lag between detection and action.

Transparent fraud reporting

Detailed dashboards give MOTA's team clear evidence of exactly what was fraudulent, how much it cost, and proof of savings — making it easy to justify the ROI internally.

The Approach

From blind spots to full visibility in four steps

Connect & audit

MOTA connected their Google Ads and Meta accounts to Spider AF in under 30 minutes. Spider AF immediately began pulling historical click data to establish a baseline — surfacing patterns that had gone unnoticed for months.

Identify fraud sources

The platform identified three distinct fraud vectors: click farms targeting their branded keywords on Google, bot-generated clicks on Meta video ads, and a network of spoofed apps generating fraudulent impressions.

Deploy exclusion rules

Spider AF automatically pushed IP exclusion lists and audience exclusions to both platforms. Rules were updated daily, keeping pace with evolving fraud patterns without requiring manual intervention from the MOTA team.

Monitor & optimise

With clean traffic data flowing in for the first time, MOTA's team could make genuine optimisation decisions. Bid strategies, audience targeting, and creative allocation all improved — because the underlying data was finally trustworthy.

The Results

Campaign performance before & after Spider AF

Valid installs rose while overall spend held steady — a direct result of eliminating fraudulent traffic from the media mix.

"We knew something was wrong, but we had no way to prove it. Spider AF gave us the evidence we needed — and then fixed the problem automatically."

Head of Performance Marketing, MOTA

The Outcome

Clean data. Real results. Confidence restored.

Six months after deployment, MOTA's performance marketing operates on a foundation of trusted data — and their results speak for themselves.

With invalid traffic eliminated, MOTA reallocated ¥2.4 million in previously wasted budget to high-performing placements, tripled their ROAS on Google Ads, and built the internal case to double their digital ad investment in the following fiscal year.

Frequently Asked

Questions about Spider AF for performance marketing

How quickly can Spider AF detect click fraud after integration?

Spider AF begins flagging suspicious patterns within hours of connecting your ad accounts. Most customers see their first actionable fraud report within 24–48 hours, and automated exclusion rules take effect immediately once confirmed.

Does Spider AF work with both Google Ads and Meta Ads simultaneously?

Yes. Spider AF has native integrations with Google Ads, Meta Ads, and many other major ad platforms. Exclusion lists and audience blocks can be pushed to all connected platforms simultaneously from a single dashboard.

Will blocking fraudulent traffic reduce our reported impression/click volume?

Yes — and that's the point. Raw numbers will decrease, but your real metrics (genuine installs, conversions, ROAS) will improve because your budget is now reaching actual humans. Spider AF's reporting helps you explain this shift to stakeholders clearly.

Can we use Spider AF for app install campaigns specifically?

Absolutely. Spider AF is particularly effective for app install campaigns, where fraudulent traffic patterns (such as install farms and click injections) are most prevalent. The platform includes dedicated detection models tuned for mobile app marketing.

Is there a minimum spend required to benefit from Spider AF?

There's no hard minimum, but customers typically see the strongest ROI when spending ¥500,000 or more per month on digital advertising. Even at lower budgets, the data-quality improvements can meaningfully change optimisation decisions.

How FIDIA Improved ROAS by 15% with Ad Fraud Prevention

The Challenge: Ad Fraud Was Eating into ROAS

FIDIA Inc. is a fast-growing Japanese company operating across lifestyle, HR, advertising, and investment. Its advertising division runs performance-based campaigns for diverse industries — from e-commerce to financial services.

As the company scaled, it faced a growing issue: fraudulent clicks were inflating costs and eroding profitability.

Google Ads and Yahoo! Ads reported some “invalid clicks,” but FIDIA’s team suspected the real impact was far greater. Sudden traffic spikes, suspicious IP activity, and unexplained conversion gaps raised red flags. With limited resources, however, the team struggled to verify or block fraud effectively.

As one manager put it, “Every click mattered. We couldn’t afford to waste even a single one.”

The Solution: Spider AF Ad Fraud Protection

An affiliate partner recommended Spider AF, prompting FIDIA to try the free ad fraud diagnosis.

The results were sobering: far more fraudulent activity than expected, especially in high-CPC categories like financial products and online clinics. This aligned with Spider AF’s broader findings — in 2024, the financial industry recorded the highest ad fraud rate at 14.3%, nearly 3x higher than the average.
