Matomo Analytics, formerly Piwik, runs as a self-hosted analytics platform with an official WordPress plugin that embeds the tracker and surfaces dashboards inside wp-admin. Data lives in tables like matomo_log_visit, matomo_log_link_visit_action, and the aggregated matomo_archive_* tables. Sites pick Matomo specifically to avoid sending visitor data to third-party analytics, which means the share-preview layer is the only remaining surface that often still leaks: most OG card services fetch from a remote endpoint each time a crawler asks.

SleekPixel renders every card locally as a cached PNG inside wp-content/uploads. The crawler fetches it from your own domain, no third-party CDN, no remote font load, no external image proxy. The card data comes from post_title, post_excerpt, the featured image, and the taxonomy assigned to the post. None of this requires Matomo at runtime: the two plugins share an audience and a privacy posture but not a single database table or hook.

For sites running Matomo's Search Console widget or the SEO Web Vitals plugin, the same top-URL list that drives Matomo's reports is the natural priority list for image coverage.

Sites pick Matomo Analytics to keep tracking data out of third-party hands. That choice is rarely casual: it reflects a privacy policy, a procurement audit, or a regulatory requirement that the visitor's path stay inside the site's own infrastructure. The og:image layer is one of the easiest places to leak that posture, because most off-the-shelf OG card services fetch the image from a remote endpoint each time a social crawler asks for it.

SleekPixel matches Matomo's posture by rendering every card locally, caching the PNG inside the WordPress uploads directory, and using only fonts and assets that ship with the plugin. There is no third-party CDN involved, no remote font fetch, no external image proxy. From the visitor's perspective and the auditor's perspective, both analytics and share previews live entirely on your own server.

That makes SleekPixel a natural pairing for any team that already chose Matomo, since the same privacy reasoning that justified Matomo also justifies the way SleekPixel renders the share card. The integration is not technical, it is positional, and it is what makes the pairing easy to defend in a DPIA or a public-sector procurement review.
