Pasting the page source and instantly seeing all competitor tags formatted for YouTube Studio is exactly what competitive research needs. The gap analysis immediately showed I was missing 3 key tags.

The multiple extraction methods (keywords meta, ytInitialData, og:video:tag) mean it works on different YouTube HTML versions. The sample HTML loader perfectly shows the expected format.

The manual entry fallback is a great safety net — if the HTML extraction doesn't find tags, I can still paste a comma-separated list and use all the analysis features. Flexible and well-thought-out.

The gap analysis showing partial keyword matches (individual words found but not the full phrase) is more nuanced than a simple yes/no. That detail helped me understand why I was ranking for some terms but not others.

YouTube removed the public display of tags from the video UI in 2021, but tags are still used by the algorithm for discovery and related videos. They remain in the page source HTML and can be extracted from there.
How do I access a YouTube video's page source?+
On any YouTube video page: press Ctrl+U (Windows/Linux) or Cmd+Option+U (Mac) to open the source. Press Ctrl+A to select all, then Ctrl+C to copy. Paste into this tool's HTML field.
Are competitor tags worth copying?+
Analysing competitor tags gives insights into which keywords they're targeting, but copying them exactly is ineffective and potentially harmful. Use competitor tags as research to understand the topic space, then create your own targeted tag set.
How many tags should a YouTube video have?+
YouTube recommends 5–15 relevant tags. Total character count should stay under 500. Quality and relevance matter more than quantity — 8 precise tags outperform 40 loosely related ones.
Do tags still matter for YouTube SEO?+
Tags are a minor ranking signal. YouTube's algorithm now relies more on title, description, thumbnail and viewer behaviour (CTR and watch time). However, tags help YouTube understand the video's topic and improve related video discovery.
