Crafting meta descriptions for better snippets (and CTR)

CTR testing

[chal00d]

I'd like to begin doing snippet testing for a few of my pages that are ranking quite well in the search engines; e.g. creating a number of different meta descriptions in order to establish which one is (hopefully) the best snippet to influence CTR.

I know PPC ninja's test this to death, though I've been looking around and not been able to find much recorded on 'snippet' testing for the organic search results.

I was hoping for something along the lines of; 'after testing 5 meta descriptions my click through rate increased by 15%'. Though also question how CTR is measured for organic rankings.

Would be interested to see if much has been written on this, or if anyone can provide some first hand experience. I've drawn a bit of a blank so far...

I would also want to see if some else is doing this test, or wait for your result, chal00d. I just wonder how you track your CTR for organic traffic?

You should be able to at least get an idea of your CTR via organic traffic by using Google Analytics to determine which keywords people clicked through to your site on, and then using Webmaster Tools - Statistics Top Search Queries to determine:

1) top queries for which your site appeared (and the position)
2) top queries which brought traffic to your site

I believe if you download the information into excel, you can view the number of queries.
