Happy New Year fellow testers! We’ve just made a change to the Website Optimizer tags that will help your pages load faster, improve data accuracy, and eliminate tracking errors when tags are not fully loaded.
The next time you go to create an experiment, you’ll be given the new tags, which use asynchronous JavaScript. Asynchronous tagging, which is already
a standard for Google Analytics, allows the Website Optimizer tracking and conversion scripts to run in parallel to your site loading. For Website Optimizer veterans, these new tags appear in Step 2 of the setup wizard — be sure to read the instructions as the installation is slightly different.
Here’s to winning experiments in the new year.
