### YouTube Algorithm Mechanics - **CTR (Click-Through Rate)** gets YouTube to test your video with initial audience pools. - **APV (Average Percentage Viewed)** determines whether YouTube expands distribution to broader home page feeds. ### Optimization Strategy Never promise an outcome in the thumbnail/title that isn't addressed directly in the first 30 seconds of the video.
