The best approach is to use ProThumbnailPreview and promote the extension based on your impressions. Write three "comments" as if you were publishing them on the Chrome Web Store. And those three "comments" are your tool for promotion and earning. Put your affiliate link and you're ready!

You sell "Confidence."

You tell your audience: "I have checked this against reality (Live Preview), I have checked if the main subject recognizable on mobile (Blur test), and I have checked it against human psychology (Increase CTR). I am ready to publish."

This is the "Pre-Flight Simulation". This is a Validation Tool.

Creators fall in love with their own thumbnails and lose objectivity. They forget the fundamental rules of psychology and composition because they have been staring at the image for hours. 

A/B testing requires to wait 7-14 days for statistically significant data.

The Pitch: "Stop waiting days for A/B test results. Use Live Preview to tweak your thumbnail in real-time. Improve visibility, adjust the text, and polish the title in seconds, not days."

It doesn't replace a A/B test, but it helps you eliminate obviously bad options before you publish or start A/B testing. You save time, avoid wasted impressions, and protect your video's early momentum.

Test if your thumbnail "pops" or gets lost in a sea of other videos before you even upload video — so you can fix it in time and get more views.

ProThumbnailPreview quickly removes subjectivity from your packaging (thumbnail + title) by showing the thumbnail in the "wild" — on the live YouTube page, among your competitors.

This gives you a real, objective picture of what your packaging looks like next to other videos that are fighting for the same viewer attention.

This allows you to improve your packaging, leading to a higher CTR and more views from the impressions that YouTube's algorithm allocates to your video.

More views → more subscribers, likes, comments, and ultimately more revenue from ads on your YouTube channel (or whatever monetization method you use).

As you've probably noticed, everyone studies and emulates viral thumbnails and headlines. It's hard to know if you've truly "hit the vibe" of a viral video until you place your thumbnail right next to theirs. ProThumbnailPreview lets you insert your thumbnail directly beside the YouTube thumbnail you're emulating — for an instant "vibe check". If yours looks like the "poor cousin" of the viral one, you'll know immediately that your packaging (thumbnail or  title) still needs work.

In a world where everyone uses AI, thumbnails are becoming similar and generic. ProThumbnailPreview helps your thumbnail stand out from the "AI crowd".

Think of ProThumbnailPreview as the 'final flight control' inside your cockpit. AI is the engine — it can generates your thumbnail, title, and script. But this tool is the instrument panel that tells you: 'You're cleared for takeoff'... or warns you before you crash.

It’s a cheat code to boost your CTR.

The focus is on context and the fact that a thumbnail never stands alone, but is always surrounded by competition.

Stop guessing.

Have you ever posted a video, got a bad CTR, and then frantically changed the thumbnail? That's because you haven't seen what he actually looks like in the feed. Our Live Preview gives you a superpower: A look into the future. Submit your idea directly to the YouTube page before you record a single second of video.  If your thumbnail doesn't win this test, it won't win when you post it either. Rule: Don't post until you see your video dominating the screen next to your competition.

✅ Real competition: How do you look next to the best in your niche?

✅ Psychological "Pop": Does the eye naturally fly to your picture?

✅ Time saving: It is better to change the design now in 5 minutes, than to watch the video fail for days.

On smaller screens, text gets tiny, elements blur, and your video disappears in the feed. With the Mobile Scroll Simulator, you can check if your thumbnail actually survives the scroll, grabs attention and gets a click.

Blur Test

The 1.8-Second Test: Viewers don't analyze your image, they scan it. You have less than 2 seconds to grab attention. If your thumbnail isn't clear when it's blurry, it won't be noticed when it's sharp. Check now what is the real focus of your image.

The human eye works in such a way that it first detects large forms and contrasts, and only then reads the text. The Blur Test shows you what the viewer actually sees while scrolling on a mobile phone in motion.  Applying the blur test to a thumbnail is to check that your visual hierarchy is clear and that the most important elements "pop" even when the image is not sharp.

If your image is a "blob" with no clear focus when blurred = Bad CTR.

If you can clearly see the subject even through the blur = Good CTR.

✅ Focal point: Does the main element (face/object) stand out immediately?

✅ Clutter: Are there too many elements that create noise?

✅ Silhouette: Is the shape of the subject recognizable without details?

✅ Speed: Simulates peripheral vision and fast scrolling.

Contrast Test

Colors can lie. The human eye first registers the difference between light and dark, and only then color. If your text or face blends into the background in black and white, your thumbnail is unreadable on many screens. Check if your design has the right "pop" effect.

Did you know that red letters on a green background may look bright, but are the same shade of gray in the black and white spectrum?

This test strips away the colors to reveal the truth about your design. This is crucial for three reasons:

Many phones have "Night Mode" (yellow filter) or low light. Contrast is what remains visible.

About 8% of the male population (your audience) has difficulty distinguishing colors. They need a good contrast.

Good contrast ensures that the subject stands out clearly from the background, rather than looking "flat".

Colors are makeup, Contrast is the foundation.

Many YouTubers make the mistake of overwhelming their thumbnails with bright colors (Neon Green, Red, Yellow), thinking that it attracts attention.

But if you convert the image to grayscale, it often happens that the "screaming" image becomes a gray blob.

If a thumbnail looks good in black and white, it will look FANTASTIC in color.

Contrast Test shows you with one click whether your text and face really stand out or blend in with the background.

✅ Readability of the text: Are the letters clearly separated from the background?

✅ Subject separation: Do you (or the main subject) "stick" to the background or pop out in front of it?

✅ Resistance to conditions: How does the image look on the screen with reduced lighting or in bright sunlight?

✅ Accessibility: Is the image clear to people with poor color vision?

Composition Test

The Rule of Thirds is commonly used for quick, efficient framing in both photography and film. Divides the image into nine equal parts, aiming for a simpler, more balanced, or sometimes "safer" composition. This rule guides the viewer's eye through the image in a more natural way, creating energy and tension instead of a static, centered frame. Effective tools for avoiding boring images.

Professional designers always look at where the focus falls (eyes of the person in the thumbnail, main object, text). Many beginner YouTubers don't know where to put a face or text. The "Rule of Thirds" shows: "Yeah, my eye should be at the intersection of the lines, not in the center." Applying the rule of thirds serves to create visual balance and direct the viewer's attention to key elements

How to apply to a thumbnail.

Focus points (Intersections): Place the most important elements (face, main object or key word) at the intersection of the lines.  The human eye naturally falls on these points first rather than on the center of the image.

Top left spot: Often called the "sweet spot" because that's where most people look first (about 41% of attention).

Subject positioning: If you have a person on a thumbnail, place their face or eyes on the top horizontal line or top slice. Place your subject in the left or right third instead of the very center. This leaves room for text in the remaining two-thirds, preventing visual chaos.

Text arrangement: Place the text along the vertical lines or in one of the corners (squares) formed by the grid.  It is best if the text occupies one side (eg the right third), while the visual focus is on the opposite side.

The "Three Elements" Rule: For maximum clarity, limit your thumbnail to three key elements (eg a face, text and one graphic symbol) and arrange them following the grid.

Landscape: The horizon should be placed in the lower or upper third of the frame, depending on whether the focus is on the sky or the ground.

Portrait: The person's eyes should be positioned on the top horizontal line, often at one of the intersecting points. 

Vertical composition is used for pictures with individual portraits, trees, waterfalls, tall buildings. Vertical lines emphasize height, size and stability.

Horizontal composition is used mainly for landscapes and panoramic images of urban areas.  Horizontal lines express serenity, calmness, i.e. "similares a la viagra". width, spaciousness and stability. 

Diagonal lines express movement, dynamics and instability.
