YouTube SEO Score
Checker
Score any public video out of 100 across the five metadata fields a creator controls, and see exactly which points are missing and what earns them back.
Paste a link to score it
Anything with an 11-character video ID works. You get one number and five factor rows, each with the specific change that earns the missing points.
What the number means
An upload checklist, not a ranking prediction
The score covers the concrete fields a creator sets at upload time. Those are worth getting right because they are free and controllable — but they are not what decides whether a video travels.
What it does measure
- Title length against the width search results actually display
- Description length, and whether it links anywhere at all
- Tag count against the range that stops diluting the accurate ones
- Hashtag count against the point where YouTube ignores them
- Whether a full 1280×720 thumbnail exists at all
What it cannot
- Click-through rate — private to the channel owner
- Audience retention and average view duration
- Whether the thumbnail is any good, only that it exists
- Whether the title is compelling, only that it fits
Honest weighting
Where this score sits among the real levers
Metadata is the floor, not the ceiling. A perfect 100 on a video nobody clicks changes nothing; a 60 on a video people watch to the end still travels.
Illustrative
The bars show order of magnitude, not measured coefficients. Read a high score as “the controllable work is done” and then spend your time on the top two bars.
The rubric
How each factor is scored
Full marks sit inside a range rather than at a maximum — too many tags scores worse than a sensible dozen, and a very long title scores worse than one that survives truncation.
| Factor | Weight | Full marks at | Why that range |
|---|---|---|---|
| HD thumbnail | 25 | 1280×720 present | The heaviest weight, because the thumbnail is the single biggest driver of whether anyone clicks. |
| Title length | 20 | 40–70 characters | Long enough to carry the search phrase, short enough to survive truncation in suggested feeds. |
| Description depth | 20 | 250+ characters, with a link | Enough room for real context and links rather than a single line of boilerplate. |
| Tag coverage | 20 | 5–15 tags | Enough to cover variants and misspellings; past fifteen the accurate tags get diluted. |
| Hashtags | 15 | 1–3 hashtags | Only the first three show above the title, and past fifteen YouTube ignores all of them. |
Ranges are drawn from YouTube's published creator guidance and observable display limits. They are conventions that hold across niches, not guarantees.
Reading a score
What to do at each band
The number is only useful if it changes what you do next. Here is the honest answer for each range.
0–39
Something basic is missing
Something basic is missing — usually the description or the HD thumbnail. Fifteen minutes of work moves this a long way.
40–64
One factor is dragging this down
Look at the fix queue — a single weak field is usually responsible for most of the gap. Fix it and re-check.
65–84
Good, with points left on the table
The remaining points are cheap but rarely decisive. Your time is better spent on the thumbnail itself or the first thirty seconds.
85–100
Metadata is done
Nothing left to optimise here. If the video still underperforms, the problem is the promise or the payoff, not the fields.
Common traps
Four ways people misuse a score like this
Every one of these is a real habit that costs creators time without moving views.
Chasing 100 on every upload
The last ten points come from the lightest-weight fields. Getting there on a weak video is effort spent in the wrong place.
Stuffing tags to raise coverage
Coverage is scored as a range, so thirty tags scores lower than twelve. More is penalised here for the same reason YouTube discounts it.
Comparing scores across niches
An 80 on a tutorial and an 80 on a vlog mean the same fields are filled in — not that the two videos will perform alike.
Re-editing old uploads for points
Worth doing on videos still getting impressions. On a two-year-old upload with flat traffic, the fields are not what is holding it back.
Questions
Frequently asked
What goes into the score?
Five publicly visible fields: HD thumbnail (25), title length (20), description depth (20), tag coverage (20) and hashtag count (15). Each is scored against a range and summed to 100.
Does a high score mean better rankings?
No. It means the controllable fields are filled in sensibly. Click-through rate and retention decide distribution, and neither is visible from public data.
Why did a well-optimised video score low?
Usually a range penalty: a very long title, or thirty-plus tags. Both are common on large channels and both score below a tighter set here, deliberately.
Can I score someone else's video?
Any public video. Scoring the top few results for a keyword you want is more useful than scoring your own in isolation — it shows what the range looks like in your niche.
Does it work for Shorts?
Yes, though read it loosely. Shorts often lack an HD thumbnail by design, so expect that factor to cost points on a video where it matters far less.
Do you store the links I check?
There is no account and no history to clear. The link is sent to our server only to look up that video's public metadata from YouTube, and the response is cached briefly so a repeat check doesn't query the API again.
