Paste any YouTube link and instantly see the tags the video is ranking for. Use them to inform your own video SEO.
Find 3–5 videos already ranking for the topic you want to rank for. Paste each URL, extract their tags, and look for tags that show up across multiple winners — those are the keywords YouTube already associates with that topic. Add them to your own video's tag list (don't copy blindly — keep them relevant to your content).
YouTube uses tags as one signal to understand what a video is about and which searches and suggested feeds to surface it in. Studying the tags of videos already winning your niche is the fastest way to reverse-engineer what works — without guessing.
