Fixed! My test function was looking for the script inside the <head> element, it'll now pickup the script anywhere in the <html> element so doesn't matter if it's placed in the footer. I double checked it for you and looks like it's picked up some traffic already from ChatGPT.
No bug here, my database is still quite small, we're covering 300K keywords at the moment and that keyword isn't inside our database. We're releasing a much larger database in the coming weeks so stay tuned. I'll add that keyword and a bit more Q&A searches around referral software for you.
Really appreciate you signing up for the beta, hope you find it useful.
