thanks for this!
really helpful!!! plus one
This extension really helped me, clean and simple, amazing!
looks like the only plugin to check GTM Events that is done well
I like this extension because it requires less clicking to view page load tags - very nice. The only thing it's missing is the ability to capture onClick tags, which is a pretty big miss. Hopefully the dev is working on this now :)
love it
Simply Great Wow! I originally rated dataSlayer in 2015 I've found it indispensable all this time
Very helpful.
Great tool to save time when testing tagging specs, thanks!
Great tool!
