Question 1

Does nih.gov declare image dimensions?

Accepted Answer

nih.gov 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 2

What headline does nih.gov use for social previews?

Accepted Answer

nih.gov's social headline is "National Institutes of Health (NIH) |" (37 characters).

Question 3

What description does nih.gov use for social previews?

Accepted Answer

nih.gov's social description reads: "Official website of the National Institutes of Health (NIH). NIH is one of the world's foremost medical research centers. An agency of the U.S. Depart…" (379 characters).

Question 4

What site name does nih.gov display on social cards?

Accepted Answer

nih.gov sets `og:site_name` to "National Institutes of Health (NIH)". This appears as a small attribution label on Facebook, LinkedIn, and Slack.

Question 5

What's the biggest issue with nih.gov's Discord preview?

Accepted Answer

Image won't fit social cards (200×200, 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 nih.gov'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`.
