About this tool
The YouTube Title A/B Test Simulator helps you compare two video titles side by side with a simple 0-100 score and a winner. You fill in your title a and title b and click “Compare Titles” — the result appears on the same page within seconds. It is free to use, needs no sign-up, and there is nothing to install.
As channels grow, creators run into questions that only come up at their stage — reading the mood of comments, predicting a thumbnail's pull, planning Shorts properly. The YouTube Title A/B Test Simulator was built for one of those moments. It is a specialist tool: narrow in scope, but genuinely useful when you need it.
It works in a few quick steps. First, type your two title ideas into Title A and Title B. Next, click Compare Titles to see both scores side by side with the reasons. Then, pick the winner, or rewrite the loser using the tips in the breakdown.
What you get is a clear, direct answer based on what you typed in. If it looks wrong, the input is the first thing to check: one mistyped number, or a pasted link with extra characters, will change the result. One thing worth knowing: length of 40–60 characters, one or two power words, a curiosity word, a number, and 5–12 clear words.
- Double-check your title a before you click “Compare Titles” — a typo or an extra space is the most common cause of a strange result.
- Keep in mind that no.
- Compare its answer with your own judgement. A specialist tool is a second opinion, not a replacement for experience.

What makes a title score well?
Length of 40–60 characters, one or two power words, a curiosity word, a number, and 5–12 clear words. The full scoring table is shown with your result.
Does a higher score guarantee more clicks?
No. The score is a simple estimate from the rules on this page. Real clicks also depend on your thumbnail, topic, audience and competition.
