Pagemetrics for Matomo
·
Pagemetrics for Matomo adds server-side, privacy-friendly analytics to WordPress. It tracks page views and downloads without using JavaScript.
Pagemetrics for Matomo adds privacy-friendly, server-side analytics to WordPress by
leveraging the pagemachine/matomo-tracking PHP library. When enabled, the
plugin sends page view and optional download events from your WordPress site
directly to a Matomo instance without loading Matomo’s JavaScript tracker.
Key benefits:
- Track page views on the server with full control over attributes such as title, URL and referrer.
- Optional download tracking rewrites file links and records the click before redirecting visitors.
- Multisite aware – network admins can define defaults, individual sites can override them.
- Respects Do Not Track and Global Privacy Control headers through the underlying library.
- Logs issues to the WordPress debug log when
WP_DEBUGis enabled.
