X-Robots-Tag
X-Robots-Tag is an HTTP header that gives robots directives (like noindex, nofollow) similar to meta robots tags—useful for non-HTML resources.
Programmatic sites can accidentally expose duplicates or "thin variants." X-Robots-Tag is a precise way to prevent index bloat.
Explanation
It allows you to control indexing behavior for PDFs, API responses, staging content, and generated variants at the HTTP layer.
Marketing Relevance
