Question 1

What are Open Graph tags?

Accepted Answer

Open Graph (OG) tags control how your page appears when shared on social media via og:title, og:image, og:description tags.

Question 2

Why doesn't my shared webpage show a preview image?

Accepted Answer

This is usually because the og:image tag is missing or the image size does not meet requirements. Use this tool to enter a URL to quickly detect missing OG tags and get fix suggestions.

Question 3

How does this tool work?

Accepted Answer

This tool fetches the target page's HTML via a CORS proxy, parses meta tags, simulates Facebook and Twitter card appearances, and detects missing OG tags.
