Question 1

What are Open Graph tags?

Accepted Answer

Open Graph tags tell social platforms what title, description, and image to show when someone shares your link. Most networks — including Facebook, X, LinkedIn, WhatsApp, Slack, and Discord — read these meta tags to build link previews.

Question 2

What size should an OG image be?

Accepted Answer

Use 1200 × 630 pixels (roughly 1.91:1) as a safe default. Keep the file under 5 MB and use JPG or PNG for the widest compatibility.

Question 3

How do I fix missing previews?

Accepted Answer

Add og:title, og:description, and og:image to your page head. Make sure tags are server-rendered — many crawlers do not run JavaScript. After fixing, use platform debuggers to refresh cached previews.

Question 4

Why is my Discord preview wrong?

Accepted Answer

Discord reads the same Open Graph tags as other platforms but surfaces og:site_name above the title. Missing or outdated tags, or a cached embed, are the usual causes. Set og:site_name explicitly and re-share after updating.

Question 5

How long should og:title be?

Accepted Answer

Keep titles under about 60 characters. Shorter titles truncate less often on mobile and leave room for the message you want people to read.

Question 6

What is the difference between Open Graph and Twitter Cards?

Accepted Answer

Open Graph is the shared standard most platforms use. Twitter Cards are X-specific tags. Platforms often fall back to OG tags, but setting twitter:card to summary_large_image gives you a full-width image on X instead of a tiny thumbnail.
