How to check Open Graph tags
- 1
Paste the page URL
Use the exact page people will share, such as a blog post or product page, since each page has its own tags.
- 2
Check the share previews
The Facebook, LinkedIn and X previews show the title, description and image each platform will use, including the fallbacks they reach for when a tag is missing.
- 3
Fix what fails
Add any missing og:title, og:description or og:image, and replace an image that is broken, too small or not an image file.
- 4
Refresh the platform caches
Platforms cache share cards. After a fix, re-scrape the URL in Facebook's Sharing Debugger and LinkedIn's Post Inspector so the new card shows.
Check the rest of the page too
The free audit covers social tags alongside titles, schema, canonicals, links and AI-search readiness.
Frequently asked questions
What are Open Graph tags?
Open Graph tags are meta tags in a page's <head>, such as og:title, og:description and og:image, that tell Facebook, LinkedIn, Slack, WhatsApp and most other apps what to show when someone shares the link. X reads them too, plus its own twitter: tags.
What size should an og:image be?
1200 × 630 pixels, a 1.91:1 ratio, as a JPG or PNG under about 1 MB. Keep important text away from the edges, since some apps crop it to a square.
Why does my old image still show after I changed it?
Platforms cache share cards, sometimes for weeks. Re-scrape the URL in Facebook's Sharing Debugger or LinkedIn's Post Inspector, or give the new image a different file name so it is fetched fresh.
Do I need twitter: tags as well?
Mostly no. X falls back to the og: tags for title, description and image. The one worth adding is twitter:card set to summary_large_image, which gives a full-width image instead of a small thumbnail.
Do Open Graph tags help SEO?
Not directly as a ranking factor. They decide how your links look when shared, and a clear card with a strong image earns more clicks and shares, which is where the traffic comes from.
