Case Study
Overview
Built a fraud screening and link-protection platform to filter bot traffic, protect campaign URLs, and give marketers real-time visibility into suspicious visits.
Problem
Campaign budgets were being drained by bot traffic, proxy farms, and repeated clicks. Teams had no unified way to filter traffic, track suspicious visits, or enforce rules per campaign.
Solution
A fraud screening API with an admin dashboard for campaigns, filters, and traffic logs, plus configurable link protection and alternate redirects.
Goals
- 1Block high-risk traffic before it reaches campaign URLs.
- 2Provide per-campaign filters with allow/block rules.
- 3Track visits with IP, device, and fingerprint context.
- 4Offer alternate “safe” redirect destinations for blocked traffic.
- 5Give admins quick visibility into traffic quality and anomalies.
Approach
- Used a rule engine with multiple match types (IP, range, host, browser, OS, country) to keep decisions explainable.
- Captured visit fingerprints and device metadata for repeat-visitor detection.
- Built a campaign manager that generates unique URLs and green/red redirect paths.
- Focused on a fast admin UI for marketers instead of a heavy BI dashboard.
Results & Impact
Outcomes
- Reduced invalid traffic on protected campaigns by ~25-35% in the first month.
- Improved marketer confidence with clear visit logs and filter rules.
- Cut manual cleanup time by automating block rules and redirects.
