I'm seeing an unusually large number of first-time visits in the counter statistics. What could cause this?
When someone visits your webpage with the Counter Stats on it, a cookie is saved on their computer. If they clear their browser cookies, when they come back they would be counted as a first-time visitor again.
If they don't have cookies enabled, or if their web browser doesn't support cookies, they would always be counted as a first-time visitor. The cookies may also be blocked by a security program on their computer.
