Please add "- adds advertisement to google search results" to the feature list! Otherwise it stays a secret feature and no one will ever know this nice feature exists.
Use this all the time for debugging GA and GTM
Perfect for testing any on site Google Analytics events or Google Tag Manager configurations. Easy to work with interface and very accurate.
Much more accurate than GTM Preview and Debug mode. Thank you!
Sencilla y práctica. Para poder observar el objeto dataLayer de forma visual sin necesidad de inspeccionarlo a través de la consola.
It's wonderful but recently it has stopped working on my local dev site. It's showing the GTM instance but not the GA. The same code works and shows just fine on production site. Not sure what this might be as it worked perfectly before and I don't recall changing anything. Other GA debugging tool called 'GA Debugger' still works fine. Otherwise a really helpful tool.
simply superb!
Very useful
Not always trustful. In general a usefool tool, but right now we experience some discrepancies between dataslayer vs GTM-debugger and where dataslayer missed some important parts, which was misleading when testing.
Really useful - thank you for this!
