If you use Ember.js, and store the JSON data in the HTML body, how will search engines crawl your site properly? In the codinghorror blog post on Discourse, it says the author found out forums were valuable because he frequently stumbled on them using search engines. Try go to a thread now. Not the list of threads, but actual forum thread on the meta.discourse.org forum. (e.g. http://meta.discourse.org/t/welcome-to-meta-discourse-org/1/23 http://meta.discourse.org/t/welcome-to-meta-discourse-org/1/... not sure how long this link will last) Search for some text from the forum post in the HTML source. It isn't there! How can you find this information on search engines then? Can search engines be reliably expected to run javascript now? EDIT: EvilTrout has a good response: "Actually we aren't using server side handlebars rendering for the Google aspect, although that's something we considered! We're using it for more boring stuff like our Oneboxes. Our site is indexable by Google and it doesn't do much fancy. On certain URLs, we generate a small HTML view of the content in the <noscript> tag. You can see this by viewing source or disabling JS in your browser. It's just a simple ERB template in Rails, and uses the same object graph that we serialize via Active Model Serializers. Google can see it and index it, we've confirmed by searching post launch. As time goes on we'll probably work more on it to make the SEO even better. As you can imagine it was tough to do when we were in stealth mode ;)" http://news.ycombinator.com/item?id=5198934 http://news.ycombinator.com/item?id=5198934
