Question 1

Does caniuse.com declare an og:type?

Accepted Answer

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

Question 2

Does caniuse.com have a social share image?

Accepted Answer

No - caniuse.com does not currently set an `og:image` or `twitter:image`. Slack will fall back to extracting an image from the page or render no preview image at all.

Question 3

What headline does caniuse.com use for social previews?

Accepted Answer

caniuse.com's social headline is "Can I use... Support tables for HTML5, CSS3, etc" (48 characters).

Question 4

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

Accepted Answer

No social share image found. Without an image, your shared links get significantly fewer clicks. Posts with images receive 2-3x more engagement.

Question 5

How can I improve caniuse.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`.
