title: SEO impact using hash urls?
body: <p>I want to use some back button support like some listed <a href="https://stackoverflow.com/questions/116446/what-is-the-best-back-button-jquery-plugin">here</a>. Since the page is usually loaded by javascript looking at the hash tags. Will it create a problem for search indexing ? Do Yahoo/Google/Bing execute the javascript to get the content ? I am also thinking of using the HTML5 state push for urls instead of hashtags wherever applicable. </p>
  
  <p>Example :- If i have a site www.a.com and clicking on a link it becomes www.a.com/#!/about . When there is a seperate request for www.a.com/#!/about the javascript will take care of loading the content. But how will search engine take care of this. What would I have to do to make this work.</p>
  
  <p>Since I am starting out now, and want to create a complete ajax site with PHP at backend and Javascript using Jquery in the frontend. Any helpful resources I can look at ?</p>
