Scroll Depth is a Google Analytics plugin that tracks how far users are scrolling. The plugin provides native support for Universal Analytics, Classic Google Analytics, and Google Tag Manager. It can also be used with any analytics service that supports events.
- There's a WordPress plugin maintained by Lon Koenig.
- There's a non-jQuery fork maintained by @leighmcculloch.
Bug reports and code contributions are welcome. Please see contributing.md.
There's a test HTML file that mocks the Google Analytics functions and writes the GA Event data to the console.
