BuySell Technologies Tackles Increasing Ad Fraud in E-Commerce with Spider AF Solution

Addressing the Rise of Ad Fraud in E-Commerce



In recent years, the rapid expansion of e-commerce has been accompanied by significant challenges, one of the most pressing issues being ad fraud. According to a recent analysis by Spider AF, it was found that the ad fraud rate in Japan averages about 5.12%, with estimated annual losses exceeding ¥151 billion. Recognizing these alarming statistics, BuySell Technologies undertook a proactive initiative to diagnose the scale of ad fraud they were suffering from.

Background: E-Commerce Growth and Increasing Ad Fraud


As e-commerce continues to grow at an unprecedented rate, the integrity of digital advertising comes under threat from fraudulent activities. Many companies, including BuySell Technologies, were unaware of the full extent of these fraudulent interactions until recent diagnostic efforts made by Spider Labs brought these issues to light. The free diagnostic service provided by Spider Labs allowed BuySell Technologies to visualize and quantify the ad fraud situation impacting their advertising investments, which has made it clear that a thorough data cleansing and optimization of advertising expenditure is essential.

Results: Improvement in Click Quality and Optimization of Ad Performance


Following the diagnostic results, BuySell Technologies implemented several key measures:
  • - Automated detection and elimination of fraudulent bot traffic: This ensures that advertising analytics reflect genuine user interactions, thereby improving the quality of clicks.
  • - Exclusion of internal access: By filtering out internal traffic data, only authentic user data is recorded, providing a clearer picture of campaign performance.
  • - Automatic application of invalidation rules at campaign and keyword levels: This streamlines the process and ensures that ineffective advertisements are promptly addressed.

These strategies proved successful, leading to reduced noise in advertising metrics. The quality improvement meant increased stability in essential performance indicators such as Return on Ad Spend (ROAS), Conversion Rates (CVR), and Cost Per Acquisition (CPA). With these advancements, the operational decision-making process also became more precise.

Insights from BuySell Technologies’ EC Division


In a statement from Shiga, a representative from BuySell Technologies’ EC division, the implementation of Spider AF has slowly yet steadily improved their ROAS. They emphasized that having trustworthy data has facilitated better investment decisions, allowing them to put funding into “only the effective areas.” The enhancement in click quality has also stabilized the assumptions underpinning their CVR and CPA metrics, which in turn has accelerated both the PDCA cycle and the precision of comparative analyses.
