Question 1

What Twitter card type does freecodecamp.org use?

Accepted Answer

freecodecamp.org uses the `summary_large_image` card type. This renders a large hero image above the title and description - the most engaging format.

Question 2

Does freecodecamp.org declare image dimensions?

Accepted Answer

freecodecamp.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's the biggest issue with freecodecamp.org's Twitter / X preview?

Accepted Answer

No og:title - falling back to <title> tag. Set og:title to control social sharing independently from your page title.

Question 4

How can I improve freecodecamp.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`.
