Identify anonymous traffic in reporting

We are using the “Collect data without using cookies” option to collect basic traffic data when a visitor does not consent to analytics cookies. I can see traffic from these users in the “Tracker debugger” and “Session log” reports alongside more detailed events from users that consent.

Is there are way to identify and exclude this anonymous traffic when building custom reports? For example, is there a anonymous session flag set that can be used to report on this traffic separately, if desired?


Hi @AnthonyA,

Welcome to our community!

Here is a guide on this exact topic How can I separate anonymous traffic from known traffic? | Piwik PRO help center

In short: the best way to tell if a session was anonymous is by checking if the IP address is (that’s the IP we assign to sessions where user did not gave a consent)

Thanks for sharing @Oliwer_Kaczmarek – very helpful.
