Yapp.js: Build large client-side applications in a structured way (friendcode.github.io)

We also built Googlee (https://github.com/FriendCode/googlee), it's a service using PhantomJS, allowing you to snapshot the HTML of any Javascript based website.

Depending on how many pages you want indexed, I would pre-index your website with Googlee (periodically) and cache the results to disk, so you can quickly serve the HTML to Google and other bots.

Feel free to shoot me an email at aaron@friendco.de if you need any help.

As AaronO said, you'll want to generate snapshot of all your pages. Normally this is done with PhantomJS and some helper scripts.

Google has documented this method here: https://developers.google.com/webmasters/ajax-crawling/

I have made a service that takes care of this for javascript sites that don't want to mess with maintaining this system themself. http://www.BromBone.com

I've been working on a server which you can run easily to facilitate SEO for single page applications. https://github.com/apiengine/seoserver

Are your URLs predictable? If that's not the case, then I highly recommend you to take a look a http://seo4ajax.com (disclaimer: I'm one of the co-founder) which is the only service that handles this problem correctly.
