Running Google Analytics in iframe?
You have to append the Google Analytics tracking code to the end of
example_page.html. The content between the<iframe>-</iframe>tag only displays for browsers, which do not support that specific tag.Should you need to merge the results from the subdomains, there's an excellent article on Google's help site: How do I track all of the subdomains for my site in one profile?
In the specific case of iframes, Google doesn't say much. I've been in the same situation but I'm glad I figured it out. I posted a walkthrough here. It's in French but you won't need to speak the language to copy / paste the code. Plus there's a demo file you can download.
Sorry, but it's not going to work. The reason is because Google Analytics uses first-party cookies. This means the cookies that GA sets are specific to the domain the code is on. In your case, the iFrame is on a third-party domain. This means you're going to have two sets of GA cookies (one set for each domain), and no real way to reconcile the data.
