Social Meta Checker

Short answer

Verify Open Graph and Twitter Card meta tags for social sharing.

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

  1. Enter a page URL or paste its HTML

  2. We fetch the raw HTML and extract OG + Twitter Card meta tags

  3. Check whether the core OG tags (title, description, image) and a Twitter Card type are present

  4. Return a pass/fail checklist and a shortened preview of the tag values found

Sample input + output
INPUT
url: https://rankproof.eu/tools
OUTPUT
Open Graph tags found: 5/5
Twitter Card tags found: 2/4

  og:title         pass
  og:description   pass
  og:image         pass
  twitter:card     pass

og:title = "Pricing — RankProof"
og:image = /og/tools.png

Who Uses This

  • Content Marketer

    Before scheduling a launch post, confirm the title, description and image tags are set.

  • Brand Manager

    Check key product and landing pages for consistent share titles and images.

  • Developer

    Spot-check social tags after every CMS template change — catch the day a regression strips og:image from new posts.

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.
