Piwik is a complete web analytics package that displays reports regarding the geographic location of visits, the source of visits (i.e. whether they came from a website, directly, or something else), the technical capabilities of visitors (browser, screen size, operating system, etc.), what the visitors did (pages they viewed, actions they took, how they left), the time of visits, and more. Piwik data shows page views only of the top 500 pages on your site. In addition to these reports, Piwik provides some other features that can help users analyze the data Piwik accumulates, such as:
- Annotations: The ability to save notes (such as one's analysis of data) and attach them to dates in the past.
- Transitions: Allows one to see how visitors navigate a website, but different in that it only displays navigation information for one page at a time.
- Goals: The ability to set goals for desired actions for visitors to take. Piwik will track how many visits result in those actions being taken.
- E-commerce: The ability to track if and how much people spend on a website.
- Page Overlay: A feature that displays analytics data overlaid on top of a website. For this function to work, your site must have a Custom SSL.
- Row Evolution: A feature that displays how metrics change over time within a report.
- Custom Variables: The ability to attach data, like a username, to visit data.
Piwik also provides features that are not directly related to web traffic statistics, such as:
- Privacy Options: The ability to anonymize IP addresses, purge tracking data regularly (but not report data), opt-out support, and Do Not Track support.
- Scheduled Reports: Reports sent regularly by e-mail or text message.
- Log Importing: A script is also provided that imports data from web server logs.
- API: Every report is accessible through a web API as well as almost every administrative function. Programs can be created to use this API.
- Mobile App: A free mobile app is provided so users can access their analytics data on their phones.
- Segments compile information for the current year. That means that if you create or edit a segment, you should be able to view data from January 1st of the current year. So, a segment has the ability to view data from an entire calendar year (January through December) but it cannot pull information from a rolling year cycle (eg: March 2015 through March 2016).
