Hi, I just ran a 5-day ad on Facebook, promoting specific products linking correctly to respective product pages. I analyze user behaviour with FB analytics, Google analytics and Hotjar. After two days Hotjar stopped recording sessions. When looking at the Google analytics source/medium l.facebook.com / referral I got a 93% - 100% bounce rate with under 1 second per session duration. There seems to have been no trace of any human visitors for more than 150 link clicks since Hotjar did not record any sessions during that period and analytics showed no user interaction with site content.
Can anyone help me figure out what happened?
