Asynchronous Tracking - Google Analytics

Asynchronous tracking is an improved way to track website visitors with Google Analytics. Unlike a traditional installation, asynchronous tracking optimizes how browsers load ga.js so its impact on user experience is minimized. It also allows you to put your Analytics snippet higher in the page without delaying subsequent content from rendering.

Although asynchronous tracking uses a different Analytics snippet and a different syntax for tracking calls, it supports the exact same tracking customizations as the traditional snippet. In fact, the asynchronous tracking syntax is also more flexible than the traditional snippet.
