Hi there!
Thanks for using our plugin. All the click data of each button is displayed in the Google Analytics account you have set for your website. When you go to the Behaviour section (left side of your screen in Google analytics) and then click on events overview you will see that there is a Event category called Buttonizer.
Event Category: Each button you have set on Buttonizer will get the event category ‘Buttonizer
Event Label: This will be the name that you have given your button in the back-end in WordPress > This way you will recognize which buttons performs better
Event Action: This will be the page on which the button is clicked
If you want to test if the Google Analytics tracking is working. You go to Real Time > Events, open another tab, go to your website and click on the button. You should see hits comming in :).
Hopefully this will help!
Good luck!
