I think there is much confusion about responsive web design in general.
It's NOT about technology, but about the ROI for a retailer’s business. You shouldn’t care if Responsive is hyped or not, but wether it’s leading to the best conversion rates and revenues. - Some sites may benefit from being responsive rather than „mobile standalone“, others may not.
We therefore made real-time A/B Tests with Responsive Design against standalone mobile websites, as we wanted to know, if we should offer this as well to our merchant and increase our own revenues.
The results with approx. 800 merchants willing to make part of this tests, were crystal clear: The conversion of a dedicated mobile website + app, beat responsive by 2-3x (100-200%)! Besides it costs a fortune if you want to do it right…
That’s why we don’t offer responsive as a technology to our merchants.
We’ve summarized these findings in some white paper on our website, which I’m not allowed to post here.
I hope that helps clarify a bit the discussion here.
