MOTA Cuts CPA and Reclaims Ad Spend After Uncovering Massive Click Fraud with Spider AF

MOTA — driving DX across Japan's automotive and real-estate markets — ran an ad-fraud diagnostic expecting to find issues in social and display. Instead, the worst offender was their highest-CPC channel: search. After implementing Spider AF, MOTA recovered several thousand dollars in the first month and improved CPA across the board.

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.

01

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.

02

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.

03

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

01

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.

02

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.

03

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.

04

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."

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.

MOTA Cuts CPA and Reclaims Ad Spend After Uncovering Massive Click Fraud with Spider AF

MOTA — driving DX across Japan's automotive and real-estate markets — ran an ad-fraud diagnostic expecting to find issues in social and display. Instead, the worst offender was their highest-CPC channel: search. After implementing Spider AF, MOTA recovered several thousand dollars in the first month and improved CPA across the board.

Overview

MOTA Inc., a company driving digital transformation (DX) in the automotive and real estate industries, operates under a clear mission:
“Bring fair trade to people around the world.”

By improving transparency, MOTA builds platforms that empower users to make confident, informed decisions when buying and selling high-value assets.

As the company scaled, so did its advertising investment. With increasing budgets, the marketing team recognized a critical need: not just improving performance, but ensuring the accuracy, transparency, and reliability of their marketing data.

To ensure their data could support ROI-driven marketing decisions, MOTA conducted an ad fraud diagnostic using specialized ad fraud detection software.

The results were unexpected.

Click fraud levels were multiple times higher than expected, revealing a major gap in their click fraud prevention strategy. Estimated losses reached hundreds of thousands of dollars annually, with fraud even detected in search ads—one of their most important acquisition channels.

After implementing Spider AF, MOTA was able to:

  • Eliminate invalid and low-quality traffic across campaigns
  • Improve CPA through cleaner data and better marketing spend optimization
  • Recover several thousand dollars in ad spend within the first month

This case study explains how MOTA uncovered hidden inefficiencies, strengthened its marketing foundation, and achieved immediate improvements in performance and ROI.

Key Results

CategoryOutcome

Financial ImpactEstimated six-figure annual loss (pre-mitigation)
CPAImproved through higher-quality traffic
Cost RecoverySeveral thousand dollars recovered (first month)
ImplementationFast, simple, and low operational overhead

Company Background: Building Transparency into Complex Markets

MOTA’s mission, “Bring fair trade to people around the world”, centers on making traditionally opaque markets more transparent and user-friendly.

Core Business Areas

SectorValue Provided
AutomotiveUsers receive pre-bid offers and engage only with top buyers
Real EstateDigitized valuation and selling processes for full transparency

Yokoyama, from the Marketing Division, explains:

“As our user base grew, our ad spend increased. We realized we needed stronger discipline—not just in budget allocation, but in the transparency of that spend and the data behind it.”

At this stage, ad fraud was not seen as a major risk. Instead, the team focused on a more fundamental question:

“We wanted to confirm whether the data we rely on for decision-making was truly reliable.”

A Critical Blind Spot: Fraud in Search Ads

Before the analysis, the team assumed fraud would primarily affect:

  • Social media advertising
  • Display campaigns

However, the diagnostic revealed a critical insight:

“Even search ads—one of our largest investment areas—contained a meaningful level of fraudulent clicks.”

This finding was especially important because:

  • Search ads typically have higher CPCs
  • Fraud in these channels leads to greater financial loss per click
  • It directly impacts CPA, attribution accuracy, and campaign optimization

Why MOTA Selected Spider AF

After evaluating multiple solutions, including global vendors, MOTA selected Spider AF based on three clearly differentiated factors.

1. Clear, Actionable Visibility into Ad Fraud

One of the biggest differentiators was how easily the team could analyze and act on fraud data in real time.

“The dashboard made it easy to see where and how fraud was occurring, even without specialized expertise.”

Spider AF enabled MOTA to:

  • Instantly identify sources of invalid traffic
  • Understand fraud patterns and their impact on performance
  • Share insights across teams without technical barriers

This removed the “black box” nature of fraud detection and turned it into a practical, data-driven workflow for ongoing optimization.

2. High-Precision Detection That Protects Performance

For MOTA, effective click fraud prevention needed to balance protection with performance.

“We were concerned that blocking fraud might also reduce real conversions. Spider AF gave us confidence that this risk was minimized.”

Spider AF delivered:

  • Accurate identification of fraudulent vs. legitimate traffic
  • Minimal false positives
  • Protection of conversion volume and high-intent users

This ensured that performance gains came from higher-quality traffic—not reduced reach, supporting sustainable and scalable ROI marketing.

3. Fast Implementation with Immediate Business Impact

Speed and ease of adoption were also key decision factors.

Spider AF provided:

  • Seamless integration with existing ad platforms
  • No complex setup or engineering dependency
  • Immediate usability with minimal training
“We were able to start quickly and without confusion.”

This allowed MOTA to move quickly from evaluation to execution, achieving measurable ROI in a short timeframe without adding operational burden.

Immediate Impact: Improved CPA and Campaign Efficiency

The impact of implementation was visible almost immediately.

“From the first month, fraud blocking was clearly working, and we saw improvements in campaign performance.”

By filtering out invalid traffic:

  • Campaign data became significantly more reliable
  • Marketing spend was reallocated toward high-quality users
  • CPA improved as overall efficiency increased

This created a stronger foundation for ongoing optimization and marketing spend optimization.

Recovering Ad Spend: Turning Losses into Measurable Returns

Beyond prevention, Spider AF enabled direct recovery of wasted budget.

Using fraud logs generated by the platform, MOTA submitted a claim to Yahoo! Ads.

“We recovered several thousand dollars in the first month.”

This had a strong internal impact:

“It wasn’t just about preventing future losses. We were also able to recover past losses. That made the value very clear, even to management. We honestly felt we should have implemented it sooner.”

Key Insight: Click Fraud Is Widely Underestimated

MOTA’s experience highlights a broader industry challenge:

  • Click fraud is often significantly underestimated
  • High-value channels like search are not immune
  • Data quality directly impacts ROI, attribution accuracy, and optimization decisions

Who Should Prioritize Ad Fraud Protection?

Yokoyama shares:

“Ideally, all companies should take action. If ad fraud becomes unprofitable, the entire ecosystem improves.”

However, priority should be given to:

  • Businesses with high CPC campaigns
  • Companies heavily reliant on search advertising
“Protecting high-cost traffic is the most effective first step in preventing losses.”

Looking Ahead

MOTA plans to further strengthen its marketing by leveraging clean, reliable data.

“By improving transparency, we aim to create an environment where users can make confident decisions.”

By continuing to improve data quality, the company aligns its marketing strategy with its broader mission of enabling fair and transparent transactions.
