Using the HTML comment tag <!-- -->
in your YouTube video description to hide keywords is a clever SEO trick—but it comes with important risks you should know about. ⚠️
đ What YouTube Says About Hidden Tags
YouTube’s monetization policies require content to follow advertiser-friendly guidelines, including how metadata (title, description, tags) is used.
Keyword stuffing, even if hidden using HTML comments, can be flagged as spammy or deceptive behavior.
YouTube reviewers check your video metadata, and if they detect attempts to manipulate search rankings without adding viewer value, it may lead to:
Limited or no ads
Monetization suspension
Channel review delays or rejection from the YouTube Partner Program
✅ Best Practices Instead
Use keywords naturally in your description by writing helpful, viewer-friendly sentences.
Avoid hiding keywords—YouTube prefers transparent, informative content.
Focus on engagement metrics like watch time, CTR, and audience retention to boost visibility.
