It looks like Google pushed out an enhancement to their queries report in their Webmaster Tools. It now gives the ability to enter a date range, and it shows the number of impressions along with the click throughs (and click through rate). And each query has a dropdown link to see the positions the term showed up in. There is also a graph that trends query volume and click through volume over time.
If you use Google Webmaster Tools, definitely check out this new feature. It’s great for SEO!
