Our Mission

We believe in transparency and trust in digital advertising. The Ads.txt Analyzer was created to help publishers, advertisers, and the broader ad tech community verify authorized digital sellers and combat advertising fraud.

By making ads.txt and app-ads.txt verification accessible to everyone, we empower the community to maintain the integrity of the digital advertising ecosystem across both web and mobile app inventory. Every verified publisher helps reduce fraud, protect brand safety, and ensure that advertising revenue reaches its rightful owners.

What We Analyze

Why This Matters

Digital advertising fraud costs the industry billions of dollars annually. Unauthorized resellers, domain spoofing, and inventory fraud hurt legitimate publishers and waste advertiser budgets across both web and mobile platforms.

The ads.txt and app-ads.txt initiatives, developed by the IAB Tech Lab, provide a simple and effective way for publishers to publicly declare who is authorized to sell their inventory. When advertisers verify these files before purchasing inventory, they protect themselves from fraud and support legitimate publishers.

How We Help the Community

• Free Dual Verification: Instantly verify both ads.txt and app-ads.txt files for any publisher without registration or fees
• Publisher Directory: We maintain a growing directory of verified publishers to help advertisers make informed decisions
• Cross-Reference Detection: Automatically identifies related files and helps you verify both web and app inventory from the same publisher
• Standards Compliance: Our analyzer follows the official IAB Tech Lab specification v1.1 to ensure accurate verification

IAB Tech Lab Specification

Our analyzer is built according to the official IAB Tech Lab ads.txt specification v1.1. This ensures that our verification process is accurate, reliable, and aligned with industry standards for both web and app inventory.

The specification includes support for OWNERDOMAIN and MANAGERDOMAIN variables, proper handling of inline comments, extension fields, country codes for MANAGERDOMAIN, and validation of data records according to the defined format.
