Twitter Card Validator (twitter:* meta tags)

Validate Twitter Card meta tags so your URLs generate correct link previews on X (Twitter) and other platforms that reuse Twitter card metadata.

This actor extracts all twitter:* meta tags, checks for common issues, and outputs both a per-page dataset and a run-level SUMMARY + REPORT.

What it checks

• Extracts meta[name="twitter:..."] (and meta[property="twitter:..."] when present)
• Missing required tags (default: twitter:card, twitter:title, twitter:description, twitter:image)
• Empty values (treated as missing)
• Duplicate tags (same twitter:* tag repeated)
• Optional: validate twitter:card type is one of summary, summary_large_image, app, player
• Optional: lightweight HTTP checks that twitter:image is accessible and is an image

Input

• Start URLs: list of URLs to check
• Max pages: limit pages processed
• Follow links / Max depth / Same domain only: depth-limited internal crawl
