Validating the presence and correctness of links in generated content is crucial for ensuring quality, accessibility, and compliance with content requirements. Links should be correctly formatted, functional, and aligned with the intended content policies.

Failure to validate links can result in:

  • Broken links – Directing users to non-existent pages.
  • Security risks – Linking to malicious or unverified sources.
  • Non-compliance – Violating content guidelines or accessibility standards.

To maintain content integrity, key evaluations are used to ensure that the output text contain any valid hyperlinks.

These evaluations help enforce link validation policies, improve content quality, and maintain proper hyperlink standards.

Ensures that the output text does not contain any valid hyperlinks. It checks whether the text is free from URLs that match standard URL formatting rules.
