The PlayerSells YouTube title optimizer scores a title out of 100 across 6 checks: length and truncation 25, subject position 20, numbers and qualifiers 15, promise words 15, clickbait risk 15, caps, emoji and punctuation 10. The whole of that arithmetic runs in the reader's browser with no request and no API key, which is deliberate: a title checker that stops working because an AI vendor's balance ran out is a wrapper, not a tool. The AI rewrites are an optional layer bolted on top and every number above them is computed without it.
Length carries the most weight because it is the only check where the title is simply not read. YouTube truncates on rendered width rather than character count, so the tool works to two measured bands: roughly 50 characters before the mobile app cuts, and roughly 70 before most desktop placements do. YouTube's own hard limit is 100 characters and a title over it is rejected at upload, so anything longer is capped at 40 out of 100 no matter how well it scores elsewhere. Under 20 characters is penalised too: a one-word title fits every surface and promises nothing, and grading it on fit alone would reward saying less. The preview on the page shows exactly which words survive on a phone.
Clickbait is scored as a trade rather than a fault. Stock phrases lift click-through and also lift early drop-off, and YouTube weighs watch time alongside clicks, so the checker names the specific phrase and the specific cost instead of banning the words. Grades run strong at 85, good at 70, fair at 55, weak at 35, poor at 0.
With a channel supplied, the tool reads its last 100 public uploads and compares the title features of the top-performing quarter against the bottom quarter, using an age-adjusted index rather than raw views. It needs at least 8 videos and refuses rather than guessing below that. When no feature separates the two quartiles by a margin worth acting on, it says so: on many channels the thumbnail and the topic are doing the work and the title format is not the lever.
Titles, view counts and publication dates come from the YouTube Data API v3. Truncation lengths are working bands measured against YouTube's current layouts, not published limits. The weights, the promise-word list and the clickbait phrase list are this model's own and are not published by YouTube. PlayerSells is not affiliated with YouTube or Google.
Read straight off the scorer, so this table cannot fall out of step with the score.
| Check | Points |
|---|---|
| Length and truncation | 25 |
| Subject position | 20 |
| Numbers and qualifiers | 15 |
| Promise words | 15 |
| Clickbait risk | 15 |
| Caps, emoji and punctuation | 10 |
| Total | 100 |
Front-load the subject. Whatever the video is actually about should be a real word inside the first two or three words. It is the part that survives every truncation, it is the strongest text signal YouTube has, and it is the part a reader uses to decide whether the video is for them.
Make the promise countable.A number, a year, a price, a duration. "Budget microphones tested" is a category; "7 budget microphones under $100" is a promise a viewer can check, and a checkable promise is a clicked one.
Write for the cut, not the field. The input box holds 100 characters and a phone shows about 50. Anything after that is for the watch page, where the viewer has already clicked.
Take the clickbait trade knowingly. A tease buys the click and spends the first thirty seconds. If the video genuinely delivers the tease in the first thirty seconds, take the trade. If it does not, you have bought a click and sold your retention.
Test against yourself, not against advice. Title conventions travel badly between niches. The comparison this tool runs against your own best and worst performing uploads is worth more than any general rule on this page, including the four above it.
YouTube's hard limit is 100 characters, but the limit that matters is where the title gets cut off. The mobile app truncates near 50 characters and most desktop placements near 70. YouTube truncates on rendered width rather than on a character count, so those are working bands and not exact rules. A title under 50 characters survives everywhere; a longer one is fine as long as the promise is in the first 50.
Length is only one of six checks and it is scored in both directions. A title over YouTube's 100-character limit is capped at 40 out of 100 because the upload form will reject it outright. A title under 20 characters, or shorter than three words, is marked down for the opposite reason: it fits everywhere and promises nothing. The other five checks look at where the subject sits, whether the promise is countable, whether a payoff word is present, clickbait risk and how loud the title is.
No, and that is the point of how it is built. The score, the checklist, the truncation preview and the fix list are pure rules that run in your browser with no request at all. The AI layer adds three rewrites on top and it can be missing, switched off or out of budget without changing anything above it.
It is a trade rather than a sin, and the tool scores it as one. Stock clickbait phrasing does lift click-through rate. It also lifts the share of viewers who leave in the first thirty seconds, and YouTube weighs watch time alongside clicks, so a title that wins the click and loses the viewer is a title that lost. The checker flags the phrases and names the trade rather than pretending the words are simply forbidden.
Given a channel, the deep check reads its last 100 public uploads, ranks them on an age-adjusted performance index, and compares the title features of its best-performing quarter with its worst. It needs at least 8 videos and it says so when there are fewer. This is the only honest way to make a claim like "numbers work on this channel", because the same claim across all of YouTube is really a statement about what kind of channel uses numbers.
Because a YouTube video keeps accumulating views for years and a growing channel published its earliest work to its smallest audience. Comparing raw view counts would rank the oldest videos highest. Each video is instead divided by the median views of the videos published either side of it, so it is only ever measured against videos with a similar age and a similar subscriber base behind them.
Yes, and position matters more than repetition. YouTube reads the title as the strongest text signal it has about a video, so the subject should be a real word in the first two or three words rather than buried after a hook. Repeating a keyword three times does nothing for ranking and costs you the characters that survive truncation.

Given a channel, the deep check reads its last 100 uploads and compares the title patterns of its best-performing quarter against its worst. Without one it still scores the title in full.
