Question 1

Does go.dev declare an og:type?

Accepted Answer

No - go.dev does not set an `og:type` meta tag. Most platforms default to `website`, but explicitly declaring it ensures consistent rendering.

Question 2

Does go.dev declare image dimensions?

Accepted Answer

go.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.

Question 3

What headline does go.dev use for social previews?

Accepted Answer

go.dev's social headline is "The Go Programming Language" (27 characters).

Question 4

What description does go.dev use for social previews?

Accepted Answer

go.dev's social description reads: "Go is an open source programming language that makes it simple to build secure, scalable systems." (97 characters).

Question 5

What's the biggest issue with go.dev's Slack preview?

Accepted Answer

Image won't fit social cards (300×313, 0.96:1). Your portrait 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.

Question 6

How can I improve go.dev'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`.
