Almost all bloggers would like to track , maintain and analyze the traffic of their blog. Most popular services to track traffic of website is Google Analytics as it is most trusted services. Now, Google analytics announced the much needed Asynchronous tracking script that optimizes the old script. Main benefit of Asynchronous tracking script is that it significantly decreases load time of the page.

Look at the below for asynchronous concept:
” When something loads asynchronously on a web page, that means it does not block other content from loading and your browser can load other things simultaneously.”

Asynchronous script allows to rendering web page while tracking JS (ga.js) loads in background So it reduce the load time of web page as previously it waits for the page to load. As a result Asynchronous calls are efficient then the normal JS calls.

Main benifits of Asynchronous Tracking is …

  • Faster tracking code load times for your web pages due to improved browser execution
  • Enhanced data collection & accuracy
  • Elimination of tracking errors from dependencies when the JavaScript hasn’t fully loaded.

If you would like to implement new Google analytics asynchronous tracking code , it is as easy as removing the old one and placing the new one. Also now you are safe to put it in the header as well.

It might catch few more visits compared to old code as if visitors quit the page before it was fully loaded than it is not possible to track this kind of visit in old code.
