Tokyo, Japan – Spider Labs Inc. (Headquarters: Minato-ku, Tokyo; CEO: Satoko Otsuki), a leading provider of ad fraud prevention solutions, has published a case study on the successful implementation of "Spider AF" at IBJ Inc. (Headquarters: Shinjuku-ku, Tokyo; CEO: Shigeru Ishizaka). By adopting Spider AF, IBJ optimized its marketing budget allocation and reduced the operational burden on its sales and inside sales teams.

Implementing "Spider AF" Reduces Advertising Fraud and Optimizes Sales & Marketing Operations

‍The Challenge: Rising Costs and Inefficiencies Due to Fraudulent Leads

IBJ generates leads through advertisements and follows up via phone and email. However, in recent years, the company has experienced a surge in fraudulent leads originating from foreign-language and MFA (Made-for-Advertising) websites. These fraudulent activities created multiple issues, including:

Unanswered phone calls and emails, making follow-ups impossible.
Leads registered with third-party contact details, causing confusion and unnecessary interactions.
Applications from non-Japanese speakers, despite the service being intended for Japanese-speaking users.

As a result, IBJ’s inside sales team faced increased workloads, making efficient sales operations challenging.

The Solution: Implementing Spider AF’s "P-MAX Fraud Detection Service"

To tackle these challenges, IBJ implemented Spider AF’s P-MAX Fraud Detection Service. The solution provided two key benefits:

✅ Optimized ad performance by eliminating fraudulent clicks and conversions.

✅ Reduced workload on internal teams by minimizing interactions with fraudulent leads.

After implementation, IBJ saw a significant reduction in fraudulent leads, preventing advertising fraud losses amounting to hundreds of thousands of yen per month. Additionally, sales and inside sales teams experienced reduced workloads, allowing them to focus on core business activities more effectively.

IBJ’s Feedback: A Transformation Beyond Cost Savings

With Spider AF, IBJ achieved more than just marketing budget optimization—it fundamentally improved how internal resources were utilized.

"If we had only considered the monetary savings, we might not have implemented the solution. However, reducing unnecessary work and enabling our team to focus on meaningful tasks has had an impact beyond cost savings. The decision was driven by a commitment to efficiency and a better work environment."
— IBJ Sales Division, Mr. Kawanobe

Digital ad fraud doesn’t just waste ad budgets; it also affects internal human resources. IBJ’s case study serves as an example for businesses aiming to enhance transparency in ad operations while improving overall efficiency.
