I want to setup google analytics for my site. I have already signed up for a GA account today.

I'm not after zen cart admin integration, and I'm quite happy just logging into my GA account to retrieve traffic data. I would like all the usual GA data + all ecommerce data available (conversion rate, searches purchased products etc.) enabled. Do I have to install one of the zen cart addons to get GA to work or can I simply paste the GA generated code into my site?

- If so, what are the required GA profile settings - heres a list of whats available to configure in google analytics>analytics settings>profile settings:

Website URL:
Default page [?] :
Time zone [?] :
Exclude URL Query Parameters:
E-Commerce Website:
Site Search [?] :
Currency displayed as:

Finally, where is the best place to paste the GA code??

Thank you
