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:
|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.
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?
