Hey Tony -
It'll track links as whatever you specify, but if you don't specify they're tracked as referrals from your branded domains, go.yoursite.com (LPs) & em.yoursite.com (Emails), for example.
If you want a link to track to google you use parameters on the end of the URL. After the end of your complete url you can use as many parameters as you want, but google will pay attention to source, medium, campaign & content. I typically never use content.
You accomplish this by starting with a question mark ? . Then utm_source=MARKETO ... & ... utm_medium=EMAIL ... & ... utm_campaign= THE-BIG-CAMPAIGN
So if you write that all out without any spaces.
http://www.yoursite.com?utm_source=Marketo&utm_medium=Email&utm_campaign=The-big-campaign

That'll give you something that looks like this with Source / Medium in the first column & campaign in the second. You'll have to update Channel groupings in Analytics' preferences to see Marketo at a top-level.
To make this easier on me I add the parameter string to templates as the URL in every URL, including logos & footers, etc.
?utm_source=Marketo&utm_medium=Email&utm_campaign={{my.Campaign}}
I went to all of the top - level folders in my instance of Marketo & added the text token, Campaign. Now on every Program I make I set the campaign name once, then every where in all of my emails & landing pages with tagged links are properly tracked to the correct campaign.
For more explaination.
