What are Open Graph tags?

Open Graph tags are meta tags that control how your page looks when someone shares its link on social media: the title, description, and image in that preview card. X (Twitter) uses its own twitter: tags but falls back to Open Graph, so getting both right means your links look polished everywhere they're shared.

Why share previews matter

A strong preview image and clear title can dramatically increase how many people click a shared link. Without Open Graph tags, platforms guess, often pulling the wrong image or no image at all. A few tags in your head give you control over that first impression.

Frequently asked questions

What are Open Graph tags?

Meta tags that tell social platforms the title, description, and image to show when your page's link is shared.

Which platforms use Open Graph?

Facebook, LinkedIn, WhatsApp, and most others. X (Twitter) uses its own tags but falls back to Open Graph when they're missing.

What image size works best?

Use 1200 by 630 pixels (a 1.91:1 ratio) for a large, crisp preview across platforms.

Why hasn't my new preview updated on Facebook?

Platforms cache previews. Use the platform's sharing debugger to force a fresh scrape after you change tags.

Do I need both Open Graph and Twitter tags?

Open Graph covers most platforms. Adding twitter:card gives you the best-looking preview on X specifically.

Where do Open Graph tags go?

In the <head> of your page, as meta tags with property attributes.

What are the essential tags?

og:title, og:description, og:image, og:url, and og:type cover the basics for a good share preview.
