We are working on a project that uses parallax to provide a great experience to the end user, and we are also trying to create a best case scenario for SEO. We have multiple keywords we are trying to optimize.
We have multiple pages with the parallax function built into it. Basically each member of the primary navigation is it's own page, with all subpages built below it using the parallax function.
Our navigation currently uses the hashbang method to provide custom URL's for each subpage. And the user is appropriately directed to the right section based on that hashbang.
www.example.com/About < This is its own page
www.example.com/about/#/history < This is a subpage that you scroll to on the About page
We are trying to decide what the best method will be for trying to optimize each subpage, but my current concern is that because each subpage is really a part of the primary page, will all those URL's be seen as duplicate content?
Currently the site can also serve each subpage as it's own page as well, so without the parallax function. Should I include those as part of the sitemap. There's no way to navigate to them unless I include them in the sitemap, but I don't want Google to think I'm disingenuous in providing them links that don't exist, solely for the purpose of SEO, but truthfully all of the content exists and is available to the user.
I know that a lot of people are asking these questions, and there really are no right answers yet, but I'm curious about everyone else's experience so far.
