I have a site that uses AJAX to query the Last.fm database and then dynamically draws a graph of the results on an HTML canvas. In the search function, I have a command that sets window.location.hash to the search parameters. I also have a function that checks if a hash was provided in the url and if so, generates the page.

For example, http://www.thenlistento.com/#!/led+zeppelin will automatically navigate to a search page for Led Zeppelin.

My question is, how do optimize this set up for SEO? Can it be done at all? I've taken a look at Google Webmaster Docs and read over the hashbang protocol, but I'm not totally sure how to apply it to my situation..or even if I can at all.

Any help/suggestions would be greatly appreciated.
