The part of a URL starting with # is called the fragment, the fragment is not sent to the server when a request is made by your browser, it is only available clientside. If you visit example.com/page#fragment the server will only see example.com/page as the request.

this should be your only route

Route::get('series', 'SeriesController@show');

inside method show you should check it's an ajax call or not and return json or html

also check if google is trying to get it with _escaped_fragment_

Thanks guys for the insight. I was definitely thinking about it all wrong, so this really helped clarify things.
