Until Oct 2012, Matomo (Piwik) was relying on Feedburner and the ‘Awareness API’ to provide RSS. It used to provide the following information:
- Reach: Reach is the total number of people who have taken action — viewed or clicked — on the content in your feed.
- Circulation: Circulation is an approximate measure of the number of users who requested your feed. This is the “Readership count”.
- Hits: Hits are a raw measure of request traffic for your feed. This metric includes automated bots requests, visitors viewing the feed but not subscribing, etc.
Unfortunately, Feedburner now owned by Google decided to shut down permanently their API. Feed Analytics could be done within Matomo and if you are interested in this project, you can leave a comment in this ticket.
