• Faster tracking code load times via improved code execution
• Improvements in data collection accuracy
• Elimination of tracking errors caused by the ga.js snippet not being fully loaded

A recent Google Analytics script test preformed by Position 2 reveal quantifiable speed increases when using the asynchronous.

Analytics Tracking Code Test Key Findings

Position 2 observed the following results from their test:

1. A 17% speed increase in page load using the asynchronous ga.js over the traditional ga.js code
2. Page placement has little effect on the asynchronous ga.js load time conpared to the traditional ga.js
3. Top of the page placement no longer slows the page load. This is important when tracking clicks is and possible while page is loading content.

Of all the new Google Analytics features we feel the there are 3 the really stand out.

1. Custom Variables
Finally! Custom variables in Google Analytics will now allow you to set up to five variables per page. This is a vast improvement over the old _setVar. You can set three types: visitor, session or page. The flexibility this will allow is amazing. This feature is even more compelling when you consider that you can now also use custom variables in advanced segments.

2. Annotations
This is very helpful. Add notes to data that will allow you to keep better track of external marketing’s effect on traffic.

3. Expanded Goals Functionality
Let’s me honest, four goals was never enough. Not a problem anymore! You now have 20 goal that are segmented into Goal groups for 5 each. This is great for grouping conversion actions. In addition to an expanded number of goals you can also track site engagement through goals.
