Mass Ads & App-Ads Checker
Extension Actions
Bulk validate ads.txt and app-ads.txt files with deterministic URL probing, IAB line parsing, and CSV export.
Mass Ads & App-Ads Checker is a professional AdOps utility designed to streamline the bulk validation of ads.txt and app-ads.txt files.
Ad operations teams, publishers, and programmatic buyers frequently need to verify seller authorization across dozens or hundreds of domains. This extension eliminates the need for manual, time-consuming checks by automating the discovery and parsing process directly within the browser.
Key Features:
• Bulk Scanning: Paste a list of domains and validate them all simultaneously.
• Smart Discovery: Automatically probes multiple URL variants (HTTP/HTTPS, with and without the 'www' prefix) to locate the active ads file, minimizing false negatives.
• IAB Standard Parsing: Accurately parses the file contents according to Interactive Advertising Bureau (IAB) standards. It filters out comments, detects false-positive HTML error pages, and precisely counts valid DIRECT and RESELLER records.
• CSV Export: Download a consolidated diagnostic report containing the resolved file URLs, scan statuses (Valid, Empty File, Error), and exact line counts for easy sharing, BI ingestion, or auditing.
• Privacy First: All processing happens locally in your browser. No data or domain lists are sent to external tracking servers.
• Customizable UI: Includes a persistent Light/Dark mode toggle for comfortable viewing during long auditing sessions.
Perfect for programmatic advertising professionals conducting routine compliance audits, inventory quality checks, or onboarding new publisher partners.
