I created a custom report to analyse visitors to a single page, with options to sort data by “Visitors” and IP Address. Piwik’s definition of “Visitors” is:
“The number of unique visitors. Every visitor is counted once, even if they visit the site or app many times in a given date.”
However, I’m noticing that the same IP address appears repeatedly yet in each instance it’s marked as a new visitor. Why is this? (It is happening much too frequently for it to be explained by different people in the same household visiting the page.)
By default Piwik PRO displays Consent Form, Consent Manager overlay, with a decision to make about data tracking. If user revokes it, you will have such an effect. Unless you disabled it for your website, you can check it like described here: Turn on or off the consent form on your site | Piwik PRO help center
