Hi Eric
I agree with Moosa the days of simply using Google Analytics to see a good picture of keywords is gone.
Have you looked at your Google Webmaster Tool?
In Webmaster tool goto 'Traffic' > 'Search Queries'. Here you will find useful information in terms of search terms, clicks, click through rate and average positions.
Here it is recommended you review the query list for expected keywords. Also compare impressions and CTR to identify how you can improve your content.
On the left hand side of this Webmaster Tool page click 'Search Queries' for more detailed info.
Hope you find it useful
Richard
