Interesting question. Assuming that all settings are correct, then the cookie deletion issue could be a plausible explanation. I’ve heard cookie deletion rates ranging from 5% to 40%, so you may have to believe what you wish or what will work best with your observed data. :)

I’d also check to insure that the profile only has email traffic. It could be that there are some visitors that are sneaking in through from a different medium because the links are not tagged correctly.

Thanks for the question,

I have added one of these filters to http://www.googleanalyticsfilters.com with reference back to you and your website. I hope this is OK. If not, please let me know.

http://www.googleanalyticsfilters.com is an attempt to create a central directory of user-submitted Google Analytics Filters.

I have a brain twister that you can perhaps provide some insight on. After creating a profile for our email customers, GA is reporting that over 50% of our visits are coming from new visitors, despite all emails are only collected via visiting our website.

In Brian Clifton’s GA book, he stated up to 30% of users delete their cookies within a month’s timeframe. What is your take on this?

All settings such as cookie duration have not altered.

Any feedback is greatly appreciated. Thanks again.

Segmenting based on a sub directory is a bit trickier. You’ll need to add a second include filter that looks at the campaign term. That’s right, the referral sub-directory is stored in the campaign term parameter for referrals.

Hope that helps,

I’m not exactly sure what you’re asking, but I think you want to see the above data for a specific referring site, correct?

In this scenario you would need to create 2 filters, as I do in the above example. The first filter, an include filter, should be a filter on the medium, and it should have a filter pattern of ‘referral’.

The second filter should, also an include filter, should be a filter on the source, and have a value of ‘the-domain-that-you-want-to-track’.

Thanks for the question and hope that helps.

Maybe something similar to this?

Would this solve that problem potentially?
