Do we need a separate mobile site?
No. A properly responsive site serves every device from one codebase and one set of URLs, which is also better for search.
Responsive Web Design
Most people will judge your business on a phone screen, standing somewhere, using one hand.

Responsive design used to mean the layout doesn't break. That bar is far too low now. The mobile experience is the primary experience, and it has to be designed first rather than squeezed down from a desktop mockup.
We design for the phone, then expand. It produces simpler, faster, more decisive pages on every screen size.
A beautiful page that takes six seconds to appear is a bad page. We keep builds lean, serve appropriately sized images, and avoid the heavy scripts that make so many modern sites sluggish.
Faster pages rank better and convert better. It's one of the few things in this field that's genuinely both.
