Should you put numbers in YouTube titles? What 10.2 million videos show
Numbers help a YouTube title, but only some kinds. A number at the start lifts the same channel's videos by 14%; an episode number costs 6%.
Yes, but only some kinds of numbers. I compared 10,215,364 long-form videos published between July 2025 and June 2026. When a channel puts a number at the start of a title ("7 mistakes...", "12 tools..."), that video typically does 1.14x better than the same channel's titles with no number. Years and money amounts help a little. Episode, part and day numbers ("Ep 45", "Day 12") do the opposite: they cost the same channel about 6% against its own unnumbered titles.
So the question is not whether a number belongs in a title. The question is what job the number is doing. A number that promises a payoff (how many, how much, how recent) earns its place. A number that only says where the video sits in a series does not.
How I measured it
Every video in this study comes from a creator channel that TubeAI serves in its research database. I kept long-form uploads only (over 60 seconds) published from July 1, 2025 to June 30, 2026, and dropped removed videos. That leaves 10,215,364 videos.
Raw view counts are a poor way to compare titles, because big channels and small channels title differently. So the main measure here is the outlier multiplier: a video's views divided by what that channel's videos published around the same time usually get. 1.0x means a normal video for that channel. 2.0x means it doubled the channel's norm. I report the median multiplier and the share of videos that reached 2x or more.
A title counts as having a number if it contains any digit. I then sorted numbered titles by what the number does: a list number at the start, a year, a money amount or big quantity, a percentage, an episode or part marker, or anything else.
Titles with numbers vs titles without
Across the whole set, titles with no number are the most common, and they perform slightly under their channel's norm. Titles that open with a number perform best.
| Title | Videos | Channels | Median multiplier | Reached 2x+ |
|---|---|---|---|---|
| No number | 6,123,522 | 156,287 | 0.99x | 18.9% |
| Number later in the title | 3,682,960 | 144,692 | 1.00x | 19.5% |
| Starts with a number | 408,882 | 73,150 | 1.04x | 21.7% |
The gaps look small at the median. They are less small at the top: a title that opens with a number is about 15% more likely to reach 2x its channel's norm than a title with no number at all (21.7% against 18.9%).
This comparison mixes channels, though. Some kinds of channel use numbers far more than others. The cleaner test compares a channel only with itself.
The same channel, with and without a number
I took every channel that published at least five numbered and five unnumbered long-form titles in the window: 83,900 channels. For each one, I compared the median multiplier of its numbered titles with the median of its unnumbered titles.
- 1.14xNumber at the startmedian across 15,106 channels
- 1.09xAny number (not episodes)median across 83,900 channels
- 59.5%Channels where numbers wonof 83,900 channels
- 0.94xEpisode / part numbersmedian across 17,804 channels
On the same channel, titles with a number (episode markers left out) typically do 9% better than titles without one. Numbered titles came out ahead on 59.5% of channels. Opening with the number is stronger again: 1.14x, with the numbered titles winning on 64% of the 15,106 channels that did it at least five times.
Episode and part numbers go the other way. On the 17,804 channels that used them, those videos ran at 0.94x of the same channel's unnumbered titles.
Which kind of number works
Splitting numbered titles by what the number does shows where the average comes from.
Chart data
| Number in the title | Videos at 2x+ their channel's median (%) |
|---|---|
| List number at the start | 22.66 |
| Year (e.g. 2026) | 22.18 |
| Money or big amount | 20.72 |
| Other number | 20.68 |
| Percentage | 20.56 |
| No number | 18.92 |
| Episode / part / day number | 14.86 |
- List numbers at the start (217,742 videos): 1.04x median, 22.7% at 2x+. They tell the viewer exactly how much they get.
- Years (612,925 videos): 1.04x median, 22.2% at 2x+. A year says the advice is current, which matters most for reviews, rankings and tutorials.
- Money and big amounts (223,983 videos): 1.02x median, 20.7% at 2x+. These carried the highest raw views of any group (4,600 at the median), mostly because finance and challenge channels use them.
- Percentages (52,271 videos): 1.03x median, 20.6% at 2x+.
- Episode, part and day numbers (889,643 videos): 0.97x median and only 14.9% at 2x+, the weakest group in the study.
The episode result is the one to notice. It is also why a plain "titles with numbers vs without" average looks almost flat: nearly 900,000 series titles pull the numbered group down. A new viewer browsing a feed cannot do much with "Part 7". It tells them they have missed six videos, and it says nothing about what this one delivers.
What number to start with
For titles that open with a number (years left out), the size of the number matters more than people expect.
Chart data
| Number at the start of the title | Videos at 2x+ their channel's median (%) |
|---|---|
| 1-3 | 20.04 |
| 4-6 | 22.87 |
| 7-10 | 25.19 |
| 11-20 | 24.48 |
| 21-50 | 21.69 |
| 51-100 | 21.14 |
| 100+ | 19.04 |
Numbers from 7 to 10 do best: 25.2% of those videos reached 2x, with a median multiplier of 1.07x. 11 to 20 is close behind (24.5%, 1.07x). Below that, the promise is too thin to stand out. "3 tips" sounds like a short video, and 1 to 3 does about as well as no number. Above 50, the number stops reading as a curated list and starts reading as a dump. 100+ falls back to 19.0%, level with titles that have no number.
Odd or even?
The old rule says odd numbers feel more authentic and get more clicks. In this data they do not. Among titles opening with a number from 3 to 20, even numbers reached 2x 24.4% of the time (73,925 videos) and odd numbers 22.9% (86,650 videos). Part of that gap is 10, a strong round number that falls on the even side. The fair reading is that parity does not matter. Pick the number that matches what the video actually covers.
What this does and does not show
These are correlations across channels in the TubeAI database, not a controlled test. A number does not cause a video to do well. Videos with list numbers tend to be a particular kind of video: structured, scannable, with a clear payoff. Some of the lift belongs to that format, not to the digit itself. The same-channel comparison removes channel size and niche from the picture, but it cannot remove topic choice.
That is also the practical lesson. A number works when it describes something real about the video. Adding "7" to a title that does not contain seven distinct things will not borrow the format's performance.
Length matters too: a number is a cheap way to say a lot in few characters, which helps when you are working under the limits covered in how long a YouTube title should be. For the structures numbers usually sit inside, see the best YouTube title formats, and for the words that pair with them, the best words for YouTube titles. If a numbered title is already live and underperforming, changing the title after upload covers what that tends to do.
How to use numbers in your next title
- Use a number when the video has a countable payoff: a list, a ranking, a price, a time frame.
- Put it first when the count is the hook ("9 settings..."). Put it later when it supports the hook ("I tested every budget mic under $100").
- Prefer 7 to 20 for lists. Below 4 sounds thin; above 50 sounds unedited.
- Add the year to content that goes stale: reviews, rankings, tool roundups, tutorials.
- Keep episode and part numbers out of the front of the title.
Questions about numbers in YouTube titles
Do numbers in YouTube titles get more views?
Some do. Across 10.2 million long-form videos, titles that start with a number reached 2x their channel's typical views 21.7% of the time, against 18.9% for titles with no number. On the same channel, a leading number lifted the median video by 14%. Episode and part numbers were the exception and performed worse.
What is the best number to use in a YouTube title?
For titles that open with a number, 7 to 10 did best, with 25.2% of videos reaching 2x their channel's norm. 11 to 20 was close behind at 24.5%. Numbers of 1 to 3 and of 100 or more did about as well as having no number.
Are odd numbers better than even numbers in YouTube titles?
Not in this data. Among titles opening with a number from 3 to 20, even numbers reached 2x 24.4% of the time and odd numbers 22.9%. The difference is small, and part of it comes from 10. Use the number that matches the video.
Should I put the year in my YouTube title?
For content that can go out of date, yes. Titles with a year reached 2x their channel's norm 22.2% of the time, against 18.9% for titles with no number. It signals that the advice or ranking is current.
Should I number my YouTube series episodes in the title?
Not at the front. Titles with episode, part or day numbers reached 2x only 14.9% of the time, and the same channel did about 6% worse with them than with its unnumbered titles. Lead with what the episode delivers and move the number to the end or the thumbnail.
