About Session Duration Predictor
Estimate how long visitors stay on your website based on bounce rate, scroll depth, and page load time. The tool predicts average session duration using a weighted formula and rates your engagement as Low, Moderate, or High with a score out of 100.
How Session Duration is Calculated
The prediction starts with a base time of 120 seconds and applies three adjustment factors: bounce factor reduces duration based on your bounce rate, scroll factor increases it based on how deep visitors scroll, and speed factor penalizes slow-loading pages.
The formula is: predicted_duration = 120s × ((100 - bounce_rate) ÷ 100) × (scroll_depth ÷ 100) × max(0.5, 1 - load_time × 0.05). Your engagement score (0-100) maps to three levels: Low (under 60s), Moderate (60-180s), and High (over 180s).
