Adding tracking pixel on multistore per domain?

Question

Im trying to add Facebook custom audience pixel on magento. Directions state to add to head file. Oiginally I added to /isolatorfitness.eu/html/app/design/frontend/base/default/template/page/html BUT it applying to all stores. Does any one know what file I need to add each code to, to apply to all stores with seperate domains. Right now we have our main Europe store that has the tracking pixel but Germany and Uk stores need there own code under there own domain.

Thank you

You can input your script in the backend in System->Configuration->Design->HTML Head->Miscellaneous Scripts.
This way you can add different scripts for different websites or store views only by changing the scope from the top left selector.

I'd suggest Marius answer as the best way of doing this, but if you want to do this on the template, I suggest you fetch the store code:

$storeCode = Mage::app()->getStore()->getCode();

Then, lets say your store codes are: uk, de and eu, you could do a switch to set your domain specific code:

switch ($storeCode) {
    case "uk":
        // your uk specific code here...
        break;
    case "de":
        // your code
        break;
    case "eu":
        //your code
        break;
}
