Why Open Graph tags matter
When you share a link on LinkedIn, Facebook, Slack, WhatsApp or X, the preview card (image, title, description) comes from the page's Open Graph tags. Without them, platforms guess, and links often appear with no image or the wrong text, which costs clicks.
The essentials are og:title, og:description, og:image (1200×630 pixels) and og:url, plus twitter:card for X.
Open Graph tags you need
| Tag | What it controls | Recommended |
|---|---|---|
| og:title | The bold headline on the card | Under ~70 characters |
| og:description | The text under the headline | One or two sentences |
| og:image | The preview image | 1200×630 px, absolute URL |
| og:url | The canonical address of the page | Your canonical URL |
| og:type | The kind of content | website or article |
| twitter:card | The X card layout | summary_large_image |
Tips for using the Open Graph checker
Use a real image
A custom 1200×630 image with readable text earns far more clicks than a logo.

Don't forget X
