SEO4Ajax is a service that makes your Ajax/JavaScript/SPA site indexable from Google, other search engines and social networks.

Snapsearch is a search engine optimisation (SEO) and robot proxy for complex front-end javascript & AJAX enabled (potentially realtime) HTML5 web applications. Snapsearch's middleware detects and intercepts requests made by search engines, then sends its own javascript enabled scrapers to cache a snapshot of your web page. The snapshot is seamlessly and transparently passed back to the search engine through your web application.
