Time on my site

[jaycarney]

When I look up recent visitor activity, on some of my visitors it says 0 seconds. Is this an error? How can they only be there 0 seconds?

The time spent on each page is calculated from the time that page is loaded to the time the next page is loaded ... if browsers visit only one page on your site, the visit length cannot be calculated and will show in your stats as 0 seconds.

The explanaiton is right there on the Visit Length page:

What can I learn from the 'Visit Length' stat?
The time between when a visitor accesses your first webpage of their visit, and when they access the last is what we call the 'Visit Length'. Unfortunately it is not possible to detect with the Standard StatCounter Project when they left your website for a different website. Instead we take the time they accessed your last webpage of their visit as their 'exit time'. Although this isn't 100% accurate it is very close and nonetheless provides a valuable insight into your visitors.

Based on this information you can see how much 'pull' and 'interest' your website is generating for your visitors. If you have a low 'Visit Length' you may want to think up more ways to encourage your visitors to stay around for longer. Offer them something more.

Common problem with Visit Length Stats
If you only install the StatCounter code on one page of your website and your visitors never reload that one page. Then your visit length will always be less than 5 seconds! It is highly recommended to install the same code on all pages of your website you want to track.
