Prerender.io allows your Ember Java Script website to be crawled perfectly by Search Engines.
Now the Question is that How prerender.io Works?
How to Install
Why You Should Be Using Prerender.io
Google wrote the AJAX crawling specification that Prerender.io follows, so your site is guaranteed to be crawled correctly by Google & other search engines.
Want to run your own server? No problem! All of the code for our Prerender server is on GitHub, right here.
If a crawler ever tries to access a page that isn’t cached, we’ll render it on the fly and cache it afterwards. That way our cache is always 100% complete!
Your cached pages are returned super-fast. We even built our middleware so you could use Redis/Memcached for sub 5ms response times. Built for speed & scale.
