Urchin Software Discontinued - What Next?

In January of 2012, Google announced development of Urchin Software would be discontinued. We at Actual Metrics were disappointed to hear the news, although we can't say we were overly surprised. Google's focus on Urchin dwindled in 2011, coinciding with the launch of a paid version of Google Analytics.

Why does my Google Analytics data differ from Urchin?

When running Google Analytics and Urchin side-by-side, it's not uncommon to see data discrepancies between the two. There are a few possible reasons for this:

Using Google Analytics and Urchin Simultaneously

If you're currently a Google Analytics or Urchin 6 customer, it is very easy to track your site's usage with both products simultaneously. Depending on the code version (ga.js or urchin.js) only one additional line of code is necessary.

For ga.js
Insert the following line above pageTracker.trackPageview();:

pageTracker.setLocalRemoteServerMode();

For urchin.js
Insert the following line above urchinTracker();: _

userv=2;

CPC Source Manager

With the release of version 6.5.00, Urchin has the ability to automatically download and process Adwords CPC data. Unfortunately, the process isn't as smooth as Google Analytics' integration with Adwords, but it's better than having to manually download Adwords data before processing.

Urchin 6.5 Unleashed to Masses

Unbelievable! After almost 3 years of silence, we've seen four versions of Urchin 6 launched in the nine months. Urchin 6.400 was followed by 2 point releases (.01 and .02) in summer 2008, and December saw the launch of 6.5.
