How Piwik PRO Works
By Anna Tomalik
Once you realize why you are collecting data, you can learn how Piwik PRO does it. This knowledge is useful because if you understand the mechanism you’ll be able to make conscious choices about data you want to have. And you’ll know what data you see in reports.
Sometimes, Piwik PRO can’t collect any data. It happens when:
- A user enabled a do-not-track setting in their browser, and you enabled a do-not-track setting in Piwik PRO (it’s up to you whether you want to respect people’s privacy or not).
- You didn’t install a tracking code on a page you want to monitor.
- You deliberately excluded an IP address, Query URL, or user agent.
In all these scenarios, the user will be invisible to Piwik PRO, and Piwik PRO will not collect any information about their visit.
Types of collected data
These are just a few pieces of information the tracking code can collect, and it can do way more if we define goals, or set up events in Piwik PRO. But these we’ll cover in an advanced course. At this point, you need to know that the tracking code works with cookies to collect useful data. Then, it passes the data to Piwik PRO, where that data is turned into reports.
