WordPress OG Tags Not Working? How to Fix Social Preview Issues

WordPress showing wrong social preview images or missing og:image? Fix common issues with Yoast SEO, Rank Math, theme conflicts, and Facebook cache.

Why WordPress OG tags fail

WordPress does not output Open Graph tags by default. You need a plugin — typically Yoast SEO, Rank Math, or All in One SEO — to generate og:title, og:description, and og:image tags. If those tags are missing, duplicated, or outputting the wrong values, social platforms show broken previews.

Step 1: Verify OG tags are present

Right-click on your live page → View Page Source → search for og:image. If you don't see it, no OG plugin is active or it's misconfigured. If you see it twice, a theme or second plugin is adding duplicates.

Step 2: Configure your SEO plugin

Yoast SEO

  1. Go to SEO → Social in WordPress admin.
  2. Enable the Open Graph metadata toggle.
  3. Set a default OG image under SEO → Social → Facebook.
  4. For individual posts: edit the post → scroll to Yoast SEO meta box → click the Social tab → upload a custom OG image.
  5. If the image field is empty, Yoast falls back to the featured image. Set one.

Rank Math

  1. Go to Rank Math → General Settings → Links and ensure “Add Open Graph meta info” is enabled.
  2. Edit the post → open the Rank Math sidebar → click Social Preview to set a per-post OG image.
  3. Under Rank Math → Titles & Meta → Global Meta, set a fallback OG image for pages that don't have a featured image.

Step 3: Fix theme conflicts

Some WordPress themes (especially older ones) add their own og:image or og:title tags, causing duplicates that confuse crawlers. To check:

  1. Search your theme's functions.php or header template for og:. If found, remove the theme output and rely on your SEO plugin instead.
  2. Deactivate other plugins one at a time and re-check source if you see duplicate OG tags.

Step 4: Fix the OG image URL

  • Image must be absolute HTTPS: if your WordPress site recently moved to HTTPS, old images stored as HTTP URLs in the database will break OG crawlers. Use a plugin like Better Search Replace to update URLs.
  • Image must be publicly accessible: membership or login-gated images cannot be fetched by social crawlers.
  • Image dimensions: minimum 200×200 px; recommended 1200×630 px. Yoast and Rank Math warn you in the social preview section if the image is too small.

Step 5: Clear caches

  1. Clear your WordPress caching plugin (WP Rocket, W3 Total Cache, etc.).
  2. Clear your CDN cache (Cloudflare, Bunny, etc.).
  3. Clear the platform cache:
    • Facebook: use the Sharing Debugger and click “Scrape Again.”
    • LinkedIn: use the Post Inspector at linkedin.com/post-inspector.
    • Twitter: use the Card Validator at cards-dev.twitter.com/validator.

WordPress multisite and WooCommerce

  • Multisite: network-activate your SEO plugin so OG tags are output on every sub-site.
  • WooCommerce products: Yoast and Rank Math both support product-level OG images — set them in the product meta box. Use the product's main image as the OG image if no custom one is set.
