🧩 Analysis chain
🌐 Web query:
Twitter Card meta tag image URL requirements absolute vs relative path
💡 Result:
For Twitter/X Cards, the twitter:image value should be a fully-qualified (absolute) URL—i.e., include scheme + host + full path, like:
<meta name="twitter:image" content="https://example.com/images/card.jpg">Relative paths (e.g., /images/card.jpg) commonly fail because Twitterbot can’t reliably resolve them when scraping. [2], [6]
Also avoid protocol-relative URLs (e.g., //example.com/image.jpg); use an explicit https:// URL instead. [8]
X’s card markup docs define twitter:image as a “URL of image to use in the card” and specify key constraints (e.g., supported formats, < 5MB, etc.). [3], [1]
Sources: X Developer Platform docs on Cards markup / Summary Card image constraints [3], [1]; reported behavior in practice that Twitter Cards require absolute (not relative / not protocol-relative) image URLs [2], [8].

Use absolute URLs for twitter:image and og:image.
Twitter/X Cards require fully-qualified absolute URLs for the twitter:image meta tag; relative paths like /logo.png will fail with Twitterbot and prevent card images from displaying. The same applies to og:image for consistency and OpenGraph compliance.
