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.

A Journey to Superior Customer Acquisition with Spider AF

Switching to Spider AF lifted the share of genuine new-customer conversions by several percentage points, directly boosting sales and restoring the accuracy of Nakajitsu's ad performance data.

In the competitive world of real estate, standing out and acquiring high-quality leads is paramount. Real Estate Shop Nakajitsu, a leading brokerage firm in Japan, faced significant challenges in its digital marketing efforts, from rising ad costs to the detrimental impact of ad fraud. Seeking innovative solutions, they turned to Spider AF to enhance their advertising efficiency and drive better results. This case study explores their journey, the obstacles they faced, and the remarkable improvements achieved with Spider AF.

The Challenge Beyond Traditional Marketing Techniques

Q: What challenges did you face with your existing advertising strategies?

Yanagi: Our primary goal is to maximize sales by acquiring new prospective customers and increasing our market share. While we've successfully established our presence in existing areas, raising awareness in newly opened markets has been challenging. We rely heavily on web advertising, but the cost-effectiveness of SEO and search listing ads was becoming an issue.

Q: Did the pandemic exacerbate these challenges?

Yanagi: Absolutely. With restricted movement, creating customer touch points online became critical. Advertising costs were rising, and we had to adapt by offering online consultations and negotiations. We needed new, cost-effective solutions to expand our customer base beyond traditional marketing methods.

Addressing Ad Fraud was a Turning Point

Q: Is this why you considered ad fraud prevention?

Hamada: Yes, we were facing issues with our ads unintentionally appearing on foreign websites while our target specifically was on the Japanese market and experiencing low-quality conversions.

Q: What was the state of your ad fraud prevention before using Spider AF?

Hamada: We used another tool internally, but its service was discontinued. We quickly adopted Spider AF, which was cheaper and more efficient. It offered broader media coverage, including newer platforms like LINE ads and Microsoft ads.

Q: What are your impressions of Spider AF?

Hamada: Spider AF covers a wide range of media, including newer platforms like LINE ads and Microsoft ads, which is an improvement over our previous tool. The documentation is well-organized, making it easy to implement and use. It visualizes budget savings from wasted clicks and includes thorough explanations of terms and points on the management screen, enhancing its user-friendliness.

Q: Do you find any difficulties in operating Spider AF?

Hamada: Once set up, it can automatically exclude audiences through the API and cover many media platforms, which is extremely helpful for marketers. Sharing information within the company and with external ad agencies became seamless since everything operates automatically once set up.

Quality Over Quantity

Q: How did the decrease in ad fraud impact your operations?

Hamada: We saw a significant decrease in low-quality conversions in addition to a change in invalid traffic. The percentage of new customers among our conversions improved by a few percent, which has a substantial impact on sales. Addressing fraudulent conversions was key to enhancing cost-effectiveness and decision-making. A high volume of low-quality conversions could lead to incorrect analysis on measurement tools like Google Analytics, and could also negatively impact machine learning processes.

Yanagi: Even a few percent improvement significantly impacts sales. Resolving fraudulent conversions was crucial for improving our advertising efficiency and ultimately increasing sales.

Continuous Improvement

Q: What are your future challenges in the advertising domain?

Yanagi: We aim to evaluate our campaigns more precisely based on ROAS and further improve cost-effectiveness. Ensuring fair assessments between our brokerage fees and new house sales, which have significant price differences, is our current challenge.

Spider AF have already saved us hundreds of dollars per month in wasted budget, showing clear and positive improvements.

Q: Do you have any messages for readers about your company?

Yanagi: Our real estate company offers a "one-stop service" that caters to all needs, including our original brand of new homes, "Asobi-Sumika." If you're considering real estate, please check out Nakajitsu.
