YouTube video SEO checker for title, description, and tags
A useful YouTube SEO checker does not spit out a fake 100/100 score. It tells you whether the title is searchable, whether the first two description lines hook, and whether tags start with the primary keyword. Youtube Optimizer is the Chrome extension that fixes those three fields inside YouTube Studio.

Score widgets do not publish better metadata
Queries like youtube seo checker and youtube video seo checker are high intent: you already have a video and you want it to rank. Most checkers grade length, keyword density, and whether you mentioned “subscribe.” They rarely rewrite the copy you will actually ship.
Youtube Optimizer is the rewrite step after the audit. Enhance the title (40–60 characters, keyword front-loaded), the description (hook in the first two lines, keyword in the first 25 words), and tags (primary keyword first, 500-character cap).
Run a metadata SEO pass in Studio
- 1
Open the video Details page
In YouTube Studio, pick the upload that is underperforming or about to go live.
- 2
Check the title first
If the title is vague, all caps, or buries the keyword after a joke, click Enhance. Keep a version you would click in suggested videos.
- 3
Check the description
The first two lines show above Show more and affect CTR. Keyword early, timestamps, CTA, then hashtags.
- 4
Check tags last
Empty or recycled tag lists waste the field. Generate a fresh set that matches this video, not last month’s upload.
What this checker treats as a fail
- ●Title longer than ~70 characters on mobile with the keyword at the end.
- ●ALL CAPS titles that look spammy in the feed.
- ●Description that starts with links or a channel trailer instead of a hook.
- ●Keyword missing from the first 25 words of the description.
- ●Tags that start with “viral” instead of the actual topic.
- ●Copy-pasted metadata reused on every video in the series.

Checker vs optimizer
Numeric SEO score sites
Easy to game. A 90 score with a click-bait title still dies in browse.
Channel audit PDFs
Useful for strategy, slow for the video you are uploading tonight.
Youtube Optimizer
Fixes the three metadata fields on the video you have open. Free daily or $25 lifetime.
Channel SEO is still video SEO, repeated
youtube channel seo checker searches usually mean “why is my whole channel stuck.” Channel art and playlists matter, but discovery still starts at each video’s title, thumbnail, and packaging. Running Enhance on your last 10 uploads is a faster channel audit than another dashboard login.
Optimize the next video in YouTube Studio
Youtube Optimizer adds Enhance buttons next to title, description and tags. Review the rewrite, apply it, publish. Free every day — or $25 once for unlimited.
Frequently asked questions
Is there a free YouTube SEO checker here?
Youtube Optimizer does not show a vanity score. It rewrites title, description, and tags in Studio. One optimization per day is free.
Can I check a competitor’s video SEO?
Open your own Studio drafts. Study competitor titles in a separate tab, then enhance your version so it is specific to your footage.
Does this replace TubeBuddy or vidIQ?
Those products bundle research, thumbnails, and more. Youtube Optimizer is narrower: AI rewrites of title, description, and tags inside Studio for $25 lifetime or free daily.
What is a good YouTube SEO score?
Ignore the score. Judge search match (would someone type this?), click-through (would you stop scrolling?), and watch time after the click.
Do you analyze the video file itself?
No. This tool optimizes the metadata fields in YouTube Studio, which is what search and suggested packaging use first.
