Google's proposal for SEO friendly AJAX

Introduction | Pretty URL | Ugly URL

Ugly URL
Google will query the Ugly URL to find the contents of a page related to the Pretty URL. This is a URL that uses the query string parameter '_escaped_fragment_' to identify the page, instead of the '#!'. The Ugly URL page should return static content (no JavaScript required) related to the information specified in the '_escaped_fragment_'.

XML SiteMap

To help the pages get indexed I also created an XML SiteMap of the Ajax Pretty URLs and submitted it to your Google Search Console.
