There’s almost no limit to what you can do with the tools that are now available, many for free (or low cost).  

I pulled the raw data from MSN Ad Center on the main keyword level.

From a Web Analtyics point of view you can do two things with this kind of data.

1. Find out what Audiences are interested in a product or service

2. Find out if your website actually matches the audiences looking for what the website provides.

For example, if your website sells Tattoos online - you’ll need to envision the people who make up "Metropolian Strugglers" and write the copy as if you were speaking to them - that will up your conversion rate. 

We shoud be able to measure that with Web Analytics using a before / after test (or A/B landing page testing - using PPC).
