Stop guessing your best (YouTube) thumbnail

Your thumbnail is your first impression and it decides whether your video gets watched or ignored. YouTube’s Test & Compare feature helps creators optimize after publishing, but by then, most impressions are already gone. BrandPulse lets you pre-test your thumbnails before upload, giving you fast, clear data on what attracts attention right away.

Real audience feedback + AI analyzed

We test your designs with real people and use AI to analyze their attention patterns. You see what captures interest, what gets ignored, and why.

Target your desired audience

Choose exactly who you want to test with. Our global human panel lets you reach real viewers who match your target audience.

Every test gets statistical validation

Each test meets strict statistical reliability standards so you can act on the data with confidence.

How Thumbnail Testing Works

BrandPulse makes creative testing simple, fast, and scientifically reliable. Unlike platforms that rely on post-launch data or opinions, we base our results on real human behavior. We give real people Opportunities To View (OTV) your thumbnails. Not through forced exposure, but as part of a natural, observed environment.

This approach shows how your thumbnails or text truly compete for attention in a crowded world.
We don’t ask what people think. We observe what they actually do. Each test combines authentic human feedback with AI analysis to deliver validated insights in just a few days.

FAQs about message testing

What is a message test?

A message test measures how well a piece of copy captures attention and communicates meaning to your target audience. With Brandpulse you see behavioral data, not just opinions.

What is the purpose of message testing?

The purpose is to know if your words will resonate before you invest in campaigns. It helps you refine clarity, relevance, and impact so you can launch with confidence.

What is an example of message testing?

Testing can range from evaluating different product taglines to comparing alternative email subject lines. Brandpulse shows which one actually gets noticed.

What is the message testing methodology?

Traditional tools rely on general surveys and panels. Brandpulse is different. We use real human attention tracking with a global panel, giving you data on what people really look at and remember.

Stopping power is the ability of a message to capture attention within the first few seconds. If your copy doesn’t stop people, it won’t persuade them. Brandpulse provides a stopping power rating so you know which message wins attention.

Concept testing looks at broad ideas and creative territories. Message testing focuses specifically on the words and copy that communicate your brand or product promise.
