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.

Let's delve into why E.N. Japan selected Spider AF and the impact it had in fighting ad fraud and invalid clicks.

Introduction

Can you briefly describe E.N. Japan's business areas and your areas of responsibility?

E.N. Japan specializes in recruitment services, aiming to improve society by connecting job seekers with companies. As an Executive Officer and Director of Digital Marketing, I oversee marketing efforts for multiple segments like "Ambi" for young professionals and "Middle Career Change" for experienced individuals.

When did you first become aware of ad fraud, and why did it become a concern?

I learned about ad fraud from a marketing article a decade ago. We promptly ceased using DSP, known for its susceptibility to ad fraud, and imposed restrictions on our digital advertising.

Over time, I realized another issue; invalid traffic. Though not as malicious as ad fraud, I initially underestimated its prevalence, assuming it was mainly associated with distributing advertisements on major platforms.

However, my vigilance persisted. In 2021, I subscribed to Spider AF's email newsletter to stay updated on countermeasures against invalid traffic. The turning point came in May 2022 when our company announced ambitious growth targets, prompting a significant increase in our advertising investment.

This raised concerns about the potential impact of undetected invalid traffic on our advertising costs. To safeguard our advertising expenses, vital for business expansion, we recognized the need to accurately assess the situation and implement appropriate measures.
