Question 6

What's the biggest issue with nasa.gov's Slack preview?

Accepted Answer

Image won't fit social cards (1024×819, 1.25:1). Your square-ish image will be cropped to 1.91:1 on Facebook, LinkedIn, and Slack, and to 2:1 on Twitter. Use 1200×630 (universal) or 1200×675 (Twitter-optimized) for predictable rendering.

How can I improve nasa.gov's social previews?

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` (800×418), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
