Avg Session Duration 0 for 2 or more pages/session??
I ran two ad on my fb page, objective: click to website and found some weird results:
fb ad set 1
bounce rate: 11.76%
average session duration: 00:00:03
fb ad set 2
bounce rate: 0%
average session duration: 00:00:00
Why the average session duration are so short or even indicated as zero when ppl are clicking more than 1 page and the bounce rate is low?
Is that some problem of my ad sets/ GA setting?
