First Glance Comparing New vs Old Google Analytics Tracking Codes

I installed the new ga.js tracking script on this blog a few weeks ago and decided to take a look today to see if there are any reporting differences. Here’s what I found for the same time period:

Google Traffic
  Old New
Total Visits: 1293 1047
Pages Per Visit: 1.28 1.57
Avg Time on Site: 00:00:23 00:01.01
Unique Referring Phrases: 783 765

Here’s a couple of screenshots of the top referring phrases. You can clearly see the differences.

Old:
Google Analytics Referring Phrases (Old)

New:
Google Analytics Referring Phrases (New)

So as you can see, there’s quite a discrepancy, even for my site which doesn’t get a lot of traffic at all. I think I’m going to have to dig into this further and compare these stats with log files to see which is more accurate. I also want to make sure that the tracking codes really do appear on every page, to make sure that isn’t skewing the stats somewhat.

I’ll post back again when I find more info. If anyone else is doing a similar test, what are you finding?
