Question 1

What Twitter card type does v0.dev use?

Accepted Answer

v0.dev sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.

v0.dev's social headline is "v0 by Vercel - Build Full-Stack Web Apps with AI" (48 characters).

What's the biggest issue with v0.dev's Twitter / X preview?

Accepted Answer

Missing og:type tag. Platforms default to "website" but explicitly setting it ensures correct rendering.

Accepted Answer

Review the recommendations above - they list specific issues and provide ready-to-paste meta tag snippets. The highest-impact fixes are usually a properly sized `og:image` (1200×675), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
