Why am I getting so many zero second visits? How can someone visit for zero seconds?
Statcounter can determine visit length in one of two ways :
1) By the movement of visitor from one page to another.
2) Or if you are using the Session Replay addon we can calculate visit length that way.
If you do not have session replay and a visitor loads only 1 page on the site unfortunately we can not determine the visit length time.
Thanks for your feedback!
