Can you tell who wrote it ? name of page author organization, institution, agency you recognize e-mail contact by itself not enough
Credentials for the subject matter ? Look for links to:
“About us” “Philosophy” “Background” “Biography”
Is it recent or current enough ? Look for “last updated” date - usually at bottom
If no links or other clues... truncate back the URL Modern poetry site
