Frequently Asked Questions

>Does it guarantee how platforms render my page??
No — the previews are CSS mockups. Google, Facebook, X, and LinkedIn each have their own crawlers, truncation rules, and caches.
>What are the recommended lengths??
Google titles ~60 characters and descriptions ~160. Open Graph titles ~88 and descriptions ~200. The tool flags when your values would be truncated.
>Why is my image not showing in the preview??
The og:image field must be an absolute URL reachable by crawlers (https, not localhost). The demo buttons insert a placeholder image so you can still preview the layout.
