Big channels make thumbnail mistakes too. A large subscriber base brings in views no matter what the thumbnail looks like, so thumbnail mistakes last much longer than they would on a smaller channel. Here are seven to avoid, with a fix for each.
1. Coasting on brand recognition
A channel with millions of subscribers gets a base of views from notifications and loyal fans. That takes away the pressure to keep thumbnails sharp. If your name doesn't earn the click on its own yet, each thumbnail has to do it.
Fix: judge every thumbnail as if the viewer has never heard of you.
2. Recycling the same facial expression
The shocked face works the first time, and maybe the tenth. After that, repeat viewers read it as "more of the same" and scroll past without noticing the topic.
Fix: match the expression to the specific video, and vary it.
3. Burying the subject in a busy background
A dramatic location is a good backdrop until it competes with the subject. If the background has more detail and contrast than the person or object you want noticed, the eye has nowhere to land.
Fix: blur, darken, or simplify the background, and give the subject a clean outline.
4. Text that repeats the title
The thumbnail and the title are separate spaces. Using the thumbnail text to repeat the title wastes half your hook.
Fix: let the title explain and the thumbnail tease. See how a thumbnail and title work together.
5. Ignoring how it looks next to the rest of the catalog
One thumbnail can look great alone. On a channel page next to twenty others with the same layout, color, and pose, none of them stand out, and viewers choosing between your videos can't tell them apart.
Fix: keep a shared brand kit, but change the focal image and the main word each time.
6. Over-promising compared to the video
A thumbnail that hints at a bigger twist than the video delivers can earn a click, but viewers who feel misled tend to leave early. Low watch time can then make YouTube less likely to recommend the video.
Fix: use the most exciting true moment from the video.
7. Never revisiting old thumbnails
Trends and viewer expectations change. An older video that still gets impressions but has a dated thumbnail is often one of the easiest places to improve click-through rate, because you already know people are interested.
Fix: once a quarter, sort your videos by impressions and review the thumbnails of the ones with weak CTR. Read how to change a YouTube thumbnail and measure the result.
A quick check for these thumbnail mistakes
- Would this thumbnail work for a channel with no subscribers?
- Is the expression specific to this video?
- Is there one clear focal point?
- Does the text add something the title doesn't?
- Does it look different from my last five thumbnails?
- Does the video deliver what it promises?
Frequently asked questions
Why do big YouTubers use exaggerated thumbnails?
Many have tested what works for their audience, and a large subscriber base cushions the downside. What works for them may not work for a smaller channel, so test your own.
Should I copy a big creator's thumbnail style?
Learn from the structure, such as layout, contrast, and text size, but use your own images and words. Copying exactly can make you look like everyone else, and repeat their thumbnail mistakes.
