Social Meta Checker
Short answer
Verify Open Graph and Twitter Card meta tags for social sharing.
What it does not do: It checks the tags in the raw HTML, not how each platform will draw the preview, and platforms cache previews and refresh them on their own schedule.
What It Does
Inspects your page's Open Graph tags (og:title, og:description, og:image, og:url, og:type) and Twitter Card tags (twitter:card, twitter:title, twitter:description, twitter:image). Returns a pass/fail check on the core tags and a preview of up to 8 of the tag values found, shortened.
Why It Matters
When a link is shared, platforms build the preview card from these tags. Without og:image, many platforms show a small or plain link that is easy to scroll past. Check the tags before launch and after every template change.
How It Works
-
Enter a page URL or paste its HTML
-
We fetch the raw HTML and extract OG + Twitter Card meta tags
-
Check whether the core OG tags (title, description, image) and a Twitter Card type are present
-
Return a pass/fail checklist and a shortened preview of the tag values found

Frequently Asked Questions
- What's the right og:image size?
- 1200×630 px (1.91:1 ratio). Minimum 600×315. Maximum 8MB. Use HTTPS URL. JPEG or PNG.
- Do I need both Open Graph and Twitter Cards?
- Open Graph covers most platforms (LinkedIn, Slack, Facebook). X (formerly Twitter) falls back to Open Graph for most fields, but it needs twitter:card to choose a card type such as summary_large_image.
- Why isn't my preview updating?
- Platforms cache previews. Facebook's Sharing Debugger and LinkedIn's Post Inspector let you refresh them; other platforms refresh on their own after a while.
- Should the og:title match the page title?
- Usually, but it does not have to. The page title is written for search results; og:title can be written for people scrolling a feed.
- What about LinkedIn-specific tags?
- LinkedIn uses standard Open Graph. Test via LinkedIn Post Inspector.
