WP Scroll Analytics is a plugin for WordPress sites which tracks how far each user scrolls down a given page and how long it takes, recording the data in Google Analytics.
You can view this data in Real Time Analytics, as well as Content > Events and Content > Site Speed > User Timings. By default, it records progress in 20% intervals (20%, 40%, 60%, 80%, and 100% page depth).
Features: - New insight into what your users actually see - Less than 2 KB (minified code) - Works in any recent version of WordPress (2.6+)
Requirements: - Google Analytics (either Universal Analytics or Classic Analytics) - jQuery 1.7 or higher
