I run a web design agency and I've set this up for one of my other businesses. Normally setting up GTM and connecting everything up is never straightforward.

Conversios has been a breeze. Something which our previous plugin wasn't capable of was GA3 and GA4 tracking simultaneously. This allows you to run both side by side and the setup was so quick. No need to even add the head/body code in and hope it works either.

I simply installed the plugin, added my GTM container and then here's the genius part...
They have a JSON file as a template which in about 3 clicks you import into your GTM and it then automatically configures everything for you for GA3, GA4, Events, Ecommerce Tracking and even FB Pixel, TikTok and everything else.

If you're not familiar with GA4 as I wasn't - a lot of events and ecommerce take 24 hours to actually show in your account, which is a big step backwards from Universal Analytics which would show everything in seconds. Revenue/Sales only show 24 hours later so don't be alarmed thinking it's not working, give it 24 hours and as soon as you've installed it, check the Real Time Traffic to see it's tracking ok.

Support has been 1st Class. I booked an initial on-boarding call and Sarath jumped on a call on time on Google Meets. English I don't think is his first language, but he spoke and understood English natively which is also a huge help as when I have spoken to Google support directly before, it can be very slow to communicate.

There are a couple of additional events which I needed help tracking with and I've left it with him to check over and make sure it's all working okay.

5* plugin 5* support. Wishing you guys the best of luck!
