What does this preview?

Title, description, og:image, and overall card layout the way Facebook, Twitter, LinkedIn, Slack, iMessage display when you share a URL.

Why preview before sharing?

Catch broken og:image, missing description, wrong title before clients or executives see them.

Are previews accurate?

Very close. Social platforms cache previews for hours-days; once cached, hard to refresh. Better to preview before sharing.

How do I refresh a cached preview?

LinkedIn: Post Inspector. Facebook: Sharing Debugger. Twitter: Card Validator. These tools force re-scrape.

Why is my preview blank?

Page is missing og:title or og:image. Add them in your CMS.

Does this work for paywall pages?

No, paywall pages return only the public version (usually blank).

How is this different from Open Graph Checker?

Preview Generator visualizes the social card; OG Checker validates the underlying tags.

Can I preview Slack/iMessage?

Same OG protocol as Facebook; preview matches.

What size should og:image be?

1200x630 (1.91:1 ratio). Smaller images get cropped or upscaled.

What if my CMS does not support OG tags?

Switch CMS or add custom code. OG tags are critical for social.
