The longer the browser stays open to the site,
the more "advertising views" get counted.

it's not time based.

If you open to a web page, and only view it for two seconds,

yes it does.

Can you provide a correct answer for the OP's original question(s)?

there is no single answer. any site can trap on a close event for any
reason. often it's when there are unsaved changes in a web form, but it

purpose, but most of the time it's annoying. it's also in the who cares
category. one extra click to close. big deal.
