Our AI analyzes your thumbnails to help improve click-through rates.

What we analyze

• Text readability — is text large enough and high contrast?
• Face detection — thumbnails with faces typically perform better
• Color contrast — does it stand out in search results?
• Composition — is the layout clean and focused?
• Consistency — does it match your channel's brand?

Thumbnail score

Each thumbnail gets a score from 0-100 based on these factors. We also compare your thumbnail CTR to your channel average.

Best practices

• Use 3 words or fewer of text
• Make text fill 20-30% of the thumbnail
• Include a face showing emotion when relevant
• Use bright, contrasting colors
• Keep a consistent style across your channel
