Social Media Link Preview

Social Media Link Preview: what it is for

Enter a page address and see a mockup of the card that appears when the link is shared on WhatsApp, Facebook, X (Twitter) and LinkedIn, with image, title, description and domain. The table checks the Open Graph tags (og:title, og:description, og:image, og:url and og:site_name), the Twitter Card, the page title and description, flags what is missing and when text is too long and will be cut.

Great for checking a page before promoting it.

How to use

1. Enter the page address.
2. Tap Show preview.
3. Fix the missing tags and check again.

When to use it

• Find out why a link shows without an image on WhatsApp.
• Check the preview before launching a page.
• Tune the title and description for social media.

Frequently asked questions

Where does the link preview come from?

From the Open Graph tags in the page code, such as og:title, og:description and og:image. WhatsApp, Facebook, LinkedIn and others read these tags when someone pastes the link. X uses the twitter: tags and falls back to Open Graph.

What is the ideal og:image size?

1200 × 630 pixels (1.91:1 ratio), under 5 MB for Facebook and preferably under 300 KB for WhatsApp to show the large image. Use JPG or PNG with the full address starting with https://.

I changed the image and the preview is still old. Why?

Social networks cache previews. On Facebook, use the Sharing Debugger to fetch again; on LinkedIn, the Post Inspector. On WhatsApp, add something like ?v=2 at the end of the link so it reads it again.

What is the ideal title and description length?

A title up to 60 characters and a description up to 155 usually show in full. Longer text is cut with an ellipsis, at different lengths on each network.
