Thumbnail Test report card

Best for A/B testing thumbnails and titles
Thumbnail Test swaps thumbnails, titles or both on a live video, daily or hourly, and compares the click-through rate each version got. There's no free plan or trial. And because it rotates versions over time rather than splitting the audience, every viewer sees each version in turn.
Who Thumbnail Test is for
- Fits if YouTube's own Test & Compare doesn't let you test enough versions
- Works for teams testing titles and thumbnails across several channels
Who Thumbnail Test is not for
- Not for you if you want to try it first, as there's no free plan or trial
- Pricey if you need the API or Zapier, which start at Pro for $37 a month yearly
- Tight if more people help, as Basic has 1 seat and each extra is $19 a month
- Watch out: tests swap the version on the live video, so viewers see each in turn rather than a split
- Skip it if you want keyword research or channel analytics, as testing is all it does
Why Thumbnail Test gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyBasic is $24 a month for one channel on yearly billing ($29 monthly), between this category's $19 middle and its dearer quarter of $24.92. The API and Zapier need Pro at $37 a month yearly, and extra seats are $19 a month.
- FFree plan and trialNothing free: no free plan and no trial. A 14-day money-back guarantee covers new subscriptions, which isn't a trial.
- CFeaturesUnlimited thumbnail, title and paired tests with any number of versions, on new or old videos, with stats per version. It does testing fully, but that's a smaller job, and tests rotate rather than split viewers.
- CEase of useNo rating on record. You connect your channel, add a Chrome extension that collects data from YouTube Studio and set up each test.
- BPlatforms and integrationsWeb and a Chrome extension, linked to YouTube Studio, with an API and Zapier from Pro. No phone or desktop app.

Keep it
Nothing Thumbnail Test does is plain enough to make in a weekend. The 4 things listed below take a company.
That makes this kind of software worth paying for, not this one in particular: 23 of the 28 other YouTube SEO tools grade higher. It costs $288 a year.
What you could not
- Search data for YouTube topics and channels.
- Splitting visitors between versions and telling you which won.
- It plugs into other products, YouTube Studio and Zapier among them, and has an API.
- Sharing with other people, which means accounts and invitations.
What this rests on. Thumbnail Test’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Thumbnail Test?
Thumbnail Test runs A/B tests on live YouTube videos by swapping in different thumbnails, titles or both, every day at midnight or every hour. At the end of a test it compares the click-through rate, views and other figures each version got. Tests can run on new or old videos, with any number of versions, and teammates can work across channels.
Worth knowing
- There is no free plan or free trial; a 14-day money-back guarantee covers new subscriptions.
- Basic covers 1 channel and 1 team member; API access, Zapier and video automation start at Pro.
- Extra team seats cost $19 a month each on every plan.
- Tests change the thumbnail or title on the live video, so all viewers see each version in turn rather than a split audience.
Key features
- Thumbnail A/B tests
- Upload as many thumbnails as you like and the tool swaps them on the live video, once a day at midnight or every hour, for A/B/C/D/E tests.
- Title and combination tests
- Test titles on their own, or title and thumbnail pairs together, to see which combination gets the most clicks.
- Test analytics
- Each version's click-through rate, views and other stats, sortable by the metric you pick; a Chrome extension collects the data from YouTube Studio.
