SEO impact using hash urls? [closed]

Question

I want to use some back button support like some listed here. 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.

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.

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 ?

See here how to use hashbangs for SEO friendly AJAX-Links.

Official Google help page about AJAX and crawlability.

Basically you serve a HTML fragment equivalent to the loaded content through a special query for each page.

Take a look at the HTML5 history API
