Question 1

Why does go.dev's Twitter card show a small image?

Accepted Answer

go.dev sets `twitter:card` to `summary`, which renders the image as a small thumbnail. To get the large hero image format, the meta tag would need to be `<meta name="twitter:card" content="summary_large_image">`.

Question 2

What Twitter card type does go.dev use?

Accepted Answer

go.dev uses the `summary` card type. This renders a small square thumbnail next to the title and description.

Question 3

What Twitter handle does go.dev associate with shared cards?

Accepted Answer

go.dev sets `twitter:site` to `@golang`. This handle is shown as attribution next to the card on Twitter.

Question 4

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 5

What headline does go.dev use for social previews?

Accepted Answer

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

Question 6

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 7

What's the biggest issue with go.dev's Twitter / X 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 8

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` (1200×675), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
