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.

Japan Airlines Cuts Ad Fraud & Achieves 15% CVR Growth in Two Months

Japan Airlines achieved a 15% conversion rate improvement in just two months by eliminating ad fraud traffic with Spider AF's protection.

Japan Airlines (JAL) increases CVR by 15% and increases ROAS by removing ad fraud with Spider AF.

The Goal: Boosting Online Sales

JAL’s main goal is to promote airline tickets and tours online, known as dynamic packages. They aimed to cultivate customers through digital advertising, primarily using search campaigns and display ads on major platforms like Google and Yahoo! Japan.

Results from a Free Trial with Spider Ad Fraud Solutions 

While JAL was aware of ad fraud, they didn’t realize the extent until they started the free trial with Spider Ad Fraud Solutions. JAL assumed their affiliation with reputable ad networks protected them, but discussions with a newspaper reporter about ad placements indicated otherwise. Previously, they manually reviewed ad placements, avoiding sites with content that could unsettle their customers, such as news about airplane accidents or controversial celebrities doing things that could offend public morals. They had been working with an advertising agency to exclude such placements manually.

Unexpected Results, Contributing to Improved Ad Effectiveness

Why Spider AF: Insights from Ad Fraud Tool Comparison

JAL first learned about Spider AF during an exhibition. The offer of a free trial to assess the ad fraud activity piqued their interest. Around the same time, they were also approached by a foreign vendor, so they compared both tools.

In collaboration with an advertising agency, they evaluated the functional differences between the tools. While both seemed similar, Spider AF stood out during the free trial. Being a Japanese tool, it provided comprehensive local support and detailed detection data, ensuring transparency. Based on the strong recommendation from a trusted advertising agency, JAL decided to implement Spider AF.

Spider AF’s Effectiveness: A/B Test Reveals 15% Improvement in Conversion Rates 

Contrary to the initial expectations, the ad fraud rate was higher than they perceived. After implementing Spider AF, JAL conducted an A/B test to compare ad performance with and without ad fraud protection. The marketing team at JAL ran campaigns with identical settings and monitored the differences. The results were surprising!

Over two months, they observed a 15% improvement in conversion rate (CVR). Additionally, the improvement in return on ad spend (ROAS) highlighted the significant impact of blocking irrelevant traffic on our ad effectiveness. Spider AF was the first tool that substantially improved the ad performance.

The cost-effectiveness of Spider AF was evident, as they could quickly recoup the investment through savings on the blocked ad budget and refunds from some advertising media.

Infrastructure for Continuous Improvement

A Key Player in Improving Ad Effectiveness and Automating Brand Safety 

JAL expressed their immense satisfaction with the results. “As the online sales department, our goal is to improve the effectiveness of our advertisements continuously, and the AB test results have shown that Spider AF will significantly contribute to this objective.

From a brand safety perspective, Spider AF has also automated many of the manual exclusion tasks we previously handled, allowing us to focus more on strategic efforts.
