Hi @daviedr
Thanks for the quick reply. I added the trigger to the end of the page URL and that does indeed automatically open the popup when pasted in to a web browser, so thanks for that.
Regarding your last point, on my website for the popup to open there is a button that needs to be pressed, rather than the popup opening automatically right away. It is only for the google analytics purposes (for tracking how many users we convert from reading a landing page to actually opening the popup) that I need the specific popup URL.
Not knowing your experience with GA, do you think this URL you have just helped me create will be one which GA will actually see traffic through when people are opening the popup for real?
Many thanks
