When I look at GA, I drill down to - Behavior > site content > landing pages

However, I cannot find the url that the unbounce page is on (courses.academy.com.tw/intensive). I can only see /566612/variants/13512002/preview. When I click this I get a 404 page missing error.

Is something wrong, or is this normal?

I would like to implement URL tracking to determine which ads are having what effect on the landing page.

Finally, my conversion rate is almost zero, so I’m desperately trying to find out if there is some technical problem, or whether the landing page is just abysmal.
