Question 1

Does youtube.com declare an og:type?

Accepted Answer

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

Question 2

Does youtube.com declare image dimensions?

Accepted Answer

youtube.com 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 youtube.com use for social previews?

Accepted Answer

youtube.com's social headline is "YouTube" (7 characters).

Question 4

What description does youtube.com use for social previews?

Accepted Answer

youtube.com's social description reads: "Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube." (126 characters).

Question 5

What's the biggest issue with youtube.com's Slack preview?

Accepted Answer

Image won't fit social cards (1200×1200, 1:1). 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.

Question 6

How can I improve youtube.com'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`.
