TubeSignal — YouTube Video Performance Score

See which YouTube videos outperform their channel size with a simple color-coded performance score.

Spot high-performing YouTube videos instantly. TubeSignal helps you quickly discover YouTube videos that perform strongly relative to the size of their channel. The extension adds the channel's subscriber count and a simple performance score directly to YouTube search results, making it easy to spot standout videos at a glance. Performance signals: 🔴 Red — low performance 🟡 Yellow — average performance 🟢 Green — high performance ⚪ Gray — small channels with fewer than 500 subscribers TubeSignal is useful for discovering high-performing videos, finding promising content ideas, researching competitors, spotting topics with strong potential, and understanding which videos outperform their channel size. Don't judge a video by views alone. A video with 100,000 views on a small channel can be a much stronger signal than the same number of views on a channel with millions of subscribers. TubeSignal makes this difference visible instantly — directly in YouTube search results. No manual calculations. Just clear signals. Find winning video ideas faster with TubeSignal.
