Question 1

Does wikipedia.org have a Twitter card configured?

Accepted Answer

No - wikipedia.org does not set a `twitter:card` meta tag. Twitter may not render any preview at all, or may try to fall back to Open Graph tags.

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 Twitter / X preview?

Accepted Answer

Missing twitter:card tag. Without this, Twitter may not show a preview card at all.

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