Tag Inspector is a proprietary browser-based application developed by InfoTrust to report and verify data about the tags loaded on a website. It has two primary features: Scanner and Realtime. Scanner is a "crawler" that browses every page on a website and detects tags using one of the most robust tag libraries in the industry. After each scan of a website is complete, Scanner will report data about the tags loaded on the website, including the tag hierarchy and if any tags are "piggybacking" on other tags. Realtime is a feature that provides comprehensive testing and validation for both QA and production environments, alerting users in real-time when anything breaks. Tag Inspector has over 2,500 unique platforms in its tag library, providing unparalleled visibility into all tags loading and the data each is collecting. Tags loading from the source, through a tag management system, or piggybacking from another third party are all identified and displayed. WebTag Inspector was born out of the necessity of InfoTrust, which provides digital analytics consulting services to companies across the globe.
