Readme github.com/martinorgla/pure-og-mopro ↗

A lightweight WordPress plugin that automatically generates Open Graph and X/Twitter Card meta tags for improved social media sharing - no ads, no upsells, one database read per request.

Features

  • Outputs a complete set of Open Graph meta tags on all singular posts, pages, and the front page
  • Automatically uses the post's featured image, with a configurable site-wide fallback
  • Includes image dimensions (og:image:width, og:image:height) so social crawlers never need to pre-fetch the image
  • Sets og:type correctly: article for posts, website for pages and the front page
  • Outputs article-specific tags (article:published_time, article:modified_time, article:author, article:section) on posts
  • Outputs X/Twitter Card tags alongside Open Graph tags
  • Adds OG namespace declarations to the <html> element
  • Settings page under Settings → Pure OG with a media library picker for the default image
