Question: What does not describe a thumbnail that has been optimized for discovery?
- The thumbnail correctly sets viewer expectations about content.
- The thumbnail is visually compelling.
- The thumbnail is low-resolution.
- Words in the thumbnail are easy to read on any screen.
Explanation
An optimized thumbnail should be clear, accurate, and easy to understand across devices. YouTube recommends using high-resolution images so the visual remains sharp in different placements and screen sizes. A low-resolution image can make the content look less trustworthy or harder to identify. Strong discovery depends on a thumbnail that helps viewers quickly understand the video and choose to watch.
Why the other options are incorrect
Viewer expectations is incorrect because accurate thumbnails help viewers understand what the video contains.
Visually compelling is incorrect because strong visual appeal supports discovery.
Easy to read is incorrect because readable text helps thumbnails work across screen sizes.
