Question 1

What is wikipedia.org's Open Graph type?

Accepted Answer

wikipedia.org declares `og:type` as `website`. This tells Slack how to categorize the content when generating a preview.

Question 2

Does wikipedia.org declare image dimensions?

Accepted Answer

wikipedia.org 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 wikipedia.org use for social previews?

Accepted Answer

wikipedia.org's social headline is "Wikipedia, the free encyclopedia" (32 characters).

Question 4

What description does wikipedia.org use for social previews?

Accepted Answer

wikipedia.org's social description reads: "Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation." (130 characters).

Question 5

What's the biggest issue with wikipedia.org's Slack preview?

Accepted Answer

Image too small for Twitter/X (250x229). Twitter/X requires at least 300x157px. Recommended: 1200x675px.

Question 6

How can I improve wikipedia.org'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`.
