3Q’s Tag Detective – A Primer

Published: December 10, 2019

Author: Shane Danaher

Tag Detective is a Chrome browser extension that allows us at 3Q, our clients, and others to monitor and QA marketing tag activity. Currently, the plugin supports Google Analytics, Google Ads, DoubleClick, Facebook, Bing, and The Trade Desk. We have plans to add LinkedIn Insight tag coverage as well.

How do we and our clients use this?

Both 3Q employees and clients use Tag Detective to learn about what information is being sent to marketing and analytics platforms from their websites; this is information typically available only to someone with a background in front-end development. Clients who have data-quality issues and/or need additional support for tagging or technical analytics have been Tag Detective’s most avid adopters.
Users employ Tag Detective to:

  • See which tags are firing on a page currently
  • Test newly placed tags for performance
  • Look for errors or omissions that might be causing problems with backend data

For instance

Let’s say you have a page with a customer lead form. When a customer submits this form, you want to fire an event to Google Analytics, a Google Ads conversion pixel, and a Facebook ‘Lead’ event.
With Tag Detective, you can go through a form submission, then open the extension to look and see which tags fired and which events they passed. If anything is misconfigured, Tag Detective will allow you to see exactly what went wrong. Similarly, if any of your events are missing, Tag Detective will make it immediately clear.
If you close the tab, but later that same day want to reference your analysis again for a presentation or meeting, you can do so by accessing Tag Detective’s ‘History’ feature.
