Copy any prompt below and paste it into your AI coding agent to run Technical SEO checks:

“Is the canonical tag present, self-referencing, and using an absolute URL?”
“Does this page have a robots meta noindex — should it be indexed?”
“Audit my URL structure — any uppercase letters, underscores, or double slashes?”
“Is there a meta refresh redirect? Should I use a 301 instead?”
“Check for duplicate content signals — same title on different URLs?”
