[Nightwing]

Buongiorno from 16 degrees C wetherby UK famous for the Wetherby Whaler Chippy

OK... on this site http://www.philpotts.co.uk/ I've  set up sub domain tracking as so:
Parent site:
http://www.philpotts.co.uk/

Sub domain
http://shop.philpotts.co.uk/

So my question is please: should a dot be placed in the sub domain line as in : _gaq.push(['_setDomainName', '.philpotts.co.uk']);

Some advice places a dot in setDomainName other advice doesnt
Any insights welcome,

Grazie,David

I know it will work fine without the extra '.' as that's the only way I have ever done it.

Hi David,

You're lucky, you don't have to include the dot in the sub domain tracking code. It's also recommended not to do so by Google's own examples in the guide about Cross Domain tracking which could be found here.

Hope this helps!

Hi!

According to the current setup in Google Analytics, you don't need the extra ".", but I don't think you'll get an error if it is present. As far as I can tell, they've been going a bit back an forth about this. You can get the proper code for your intended setup in Google Analytics at Admin > Property > Tracking Info.

Hope this helps :)Anders
