Yesterday, Google announced their new Google Analytics tag to speed up page loads that will become the default code snippet provided for profiles. This is right in line with Google’s new obsession with page speed.
While the new Google Analytics tag is very light, if you start to add a lot of scripts to a site like I do, they start to add up. Allowing for the asynchronous loading (separate processing) of the tag your webpages will load that much faster and therefore the code snippet will not penalize your site speed nor your visitor’s experience.
I recommend you go back to all of your Google Analytics-tagged pages and change them out to this new snippet. Likewise, you really need to look into the load times of your webpages. It could be hurting your rankings.
