It is a tricky topic, as stateful AJAX applications can not be normally crawled simply by loading the page.

Anyhow, I'm writing this article mainly to test if Google manages to index the demo pages:
- Mercury: Vaadin app state with #!mercury, crawlable HTML.
- Venus: Vaadin app state with #!venus, crawlable HTML.
- Earth: Vaadin app state with #!earth, crawlable HTML.
- Mars: Vaadin app state with #!mars, crawlable HTML.
