Yes - Google Webmaster Tools is MUCH better for looking at what's going on with your own site. And huge congrats on your rankings and traffic! Organic traffic usually converts higher than any other source and the visitors behind it seem to engage better too. And it's free! In marketing one of the big metrics we have to account for with clients is cost of customer acquisition. Gotta love when that cost is 0 dollars! Organic search traffic also tends to bring customers who become repeat customers - so the true value of that customer over time is often much higher than with other types of traffic.
