Why does the preview still show the old OG image?

Most platforms cache previews. Trigger a re-scrape (Facebook Sharing Debugger, LinkedIn Post Inspector), or change the og:image URL (e.g. add ?v=2) to bust cache.

What OG image size should I use?

A safe default is 1200×630 (1.91:1). Smaller or wrong ratio images may look blurry or get cropped.

Do I need Twitter cards if I already have Open Graph?

Not strictly, but adding twitter:card and twitter:image improves consistency on X/Twitter.

Open Graph Preview & Debugging

Social previews don’t directly rank, but they impact click-through and sharing. This guide covers the OG checklist and the debugging workflow.

1) Minimum OG checklist

html

<meta property="og:type" content="website" />
<meta property="og:title" content="OG Preview Tool" />
<meta property="og:description" content="Check how your link looks on social platforms." />
<meta property="og:url" content="https://example.com/tools/og-preview" />
<meta property="og:image" content="https://example.com/og-image.png" />

<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="https://example.com/og-image.png" />

2) OG image best practices

Size: 1200×630 (1.91:1) is the most compatible
Format: PNG/WebP/JPEG—compress and keep it reasonably small
Text: keep critical text away from edges (safe area)
Caching: rename the file or add a version query parameter

3) Validate with our OG Preview tool
