Google analytics question - best practice?

Do you use same tracking ID for your website and for OR widgets?

of different ones?
In 1st case, using different ones example: my overall website GA tracking id is xxxx-1. My OR widgets GA ID is xxxx-2. They are tracked as separate "pages" by google using different user counts etc.

in 2nd case, using same GA ID, If I use xxxx-1 on both OR widgets and on website, I think that overall website traffic will be overstated as some users will be counted twice. Such as it is counted once as person looking at webpage and 2nd time as he/she is looking at embedded calendar (widget) within same page but essentially it is the same user on the same page.

any good practice around this?

On my website, I use the same ID. The reason is I like to be able to follow users across and set up goals etc. to see what the flow is and it's hard if you use different id's.

Under the covers, Google should handle the counting -- you want to look at the unique visitors count where they drop out duplicates, and that way it doesn't matter if they were on both the site and the widget or on multiple pages on both.

Thank you!
