I'm working with a large video-based site moving from an m. strategy to a one-URL site strategy. When I asked if they were going to responsive design they said 'not exactly'.
They're serving slightly different HTML (not just css) templates for desktop / tablet / touch-mobile / dumbphone.
Reading through the Google documentation they emphasize responsive design, and the 'same HTML' being served on a one-URL site. My question is, just how similar does that HTML have to be?
In this case they would serve fewer videos per page, for example, on mobile.
I can push for making things as similar as possible between versions in terms of text and links, but is that enough for Google, or does the HTML really need to be the *same*? Right now they say about 75% identical links and content, moving towards 90% in v 2.
I can't imagine this is a unique case, but I can't seem to find definitive answers out there, just a whole lot of 'responsive-design is recommended'.
