Google Conversion Tracking code
Google Conversion Tracking code

 10:28 pm on Jan 8, 2006 (gmt 0)

I told my Atlas rep that I was thinking of putting the Google Conversion Tracking code & the Yahoo Conversion Tracking code on our website. This way, we could eliminate Atlas.

Atlas told me that if I went that route, I would have duplication of data. Here’s why: If someone initially came to us thru Yahoo, and left the site, then they came back to us thru Google…and converted…Yahoo would “remember” the visitor, and count it as a conversion. Also, the example works the same way if they came to us from Google initially, and left. Then, returned to us using Yahoo and converted. Google would count it as a conversion. Thus, my data would show 2 conversions. One for Yahoo, and One for Google. Not, the 1 conversion that it truly is.

Here's my question.....
Is the conversion tracked back to specific referrer code within the parameters of the query string? Thereby, negating what the Atlas rep said?

Is the URL query string parameter the only thing to trigger a conversion by the Google tracking code?

If I understand you correctly:

Is the URL query string parameter the only thing to trigger a conversion by the Google tracking code?

No, it's the cookie that gets planted in the user's browser, at least in non-cross-conversion tracking.

FWIW, I insert *both* G and AdBrite tracking code in my conversion pages, which works fine, *and* do a limited amount of cross-channel tracking by G of AB ads, triggered by the "gad" URL parameter. So far, so good, IMHO.

I'm still not sure that I've answered your question though... Bv<

We don't set a cookie though.

G sets a cookie when the user clicks though a Google ad in the SERPs or in content, etc... (As I understand it: don't ask me I'm only a CTO!)

Whenever you use two separate systems, there will be crossover as those two systems aren't talking to each other. However, the number of people that fall into the above scenario seems pretty small.

If you use a single conversion tracking system, either Google Analytics, Google Conversion tracking (and cross channel tracking for engines) or any other 3rd party (Overture does not support cross channel) tracking system, the numbers will be combined.

Of course, you're still faced with asking other questions of other potential tracking systems.
1. Is the sale attributed to the first or last click?
2. How long is the cookie duration?
3. What happens if they buy from me 3 different times?
4. etc...

Hi Shimsand,

Just use to different landingpages for the 2 different engines, ones cookie or tracking will never overlap the other.
