Free YouTube SEO, hashtag & description generator
Most videos never get discovered — not because the content is bad, but because YouTube can't tell what the video is about. Your title, tags, hashtags and description are the signals the algorithm reads to decide who sees your video in search and suggested feeds. This free tool builds all of those signals for you in seconds, using the same live autocomplete data YouTube shows in its own search box, so your metadata matches what real viewers are actually typing.
Use Generate New Video SEO before you upload to turn a topic into a complete pack, or use Audit & Upgrade Video Link to score a video you have already published and get an improved description, hashtags and tags to paste into YouTube Studio.
How it works
Type your video idea and pick a category, or paste any public YouTube URL.
Real YouTube autocomplete suggestions are expanded across search-intent variations of your topic.
Get keywords, hashtags, a 500-char tag string and a full description — one click to copy each.
What you get
Real-time trending keywords sourced from YouTube's own suggestions; a set of relevant, deduplicated hashtags; a general tags string packed to fit YouTube's 500-character limit with your most relevant terms first and a live character counter; and a fully structured description with highlights, timestamps, a call-to-action and a keyword block. In audit mode you also get the video's title, channel and thumbnail, an SEO score, and a checklist of specific issues to fix.
Frequently asked questions
Is the YouTube SEO generator free?
Yes — completely free and no login. Enter a topic or paste a YouTube link and get keywords, hashtags, a 500-character tag string and a full description in seconds.
Where do the trending keywords come from?
From YouTube's own live autocomplete — the same suggestions you see when typing in the YouTube search box — expanded across several search-intent variations of your topic and blended with proven category tags.
How does the video link audit work?
Paste any public YouTube URL. The tool reads the video's public title, channel and thumbnail via YouTube oEmbed, checks the description for length, hashtags, timestamps and a call-to-action, scores its SEO, and generates an upgraded description, hashtags and tags for YouTube Studio.
Do the tags respect YouTube's 500-character limit?
Yes. The tag string is packed to fit within YouTube's 500-character tag box, prioritizing your most relevant keywords first, with a live counter showing exactly how many characters you are using.
Will this guarantee more views?
No tool can guarantee views. Good metadata makes your video easier for YouTube to understand and surface, but watch-time, thumbnails, titles and content quality still decide performance. Use this as a strong starting point, then refine.
