Colon Format
Whether the title uses a colon, usually in a 'Topic: Hook' structure. This format establishes context before delivering the specific angle.
The colon format can work when the topic label is a known search term (e.g., 'Project 2025: What You Need to Know'), but it often wastes characters on categorization when the hook alone would be stronger. It also reads as academic or journalistic rather than native YouTube.
Average Video is the effect on a typical video. Top 10% Video is the effect on the videos that broke out (top decile of views) — so you can see whether a factor helps most videos a little, or pushes the top performers much higher.
When present
The title uses a colon to separate a topic label from the specific hook.
