Meta (Facebook Insights): deprecated metrics - June 2026

Meta has deprecated a set of reach and impressions metrics across the Facebook Page Insights API as part of Graph API v25.0 (released February 18, 2026).

⚠️ Important: The new metrics listed below are not 1:1 replacements for the deprecated ones. They use a different measurement methodology (total unique media views vs. the former reach/impressions model). Historical data for removed metrics will no longer be available via the API.
