Ideas, insights and inspirations.

As Responsive Design has matured to a position of dominance in the web design and development world, so have our heads been filled with anecdotal evidence (i.e., non-evidence) about the ROI of Responsive Web Design. (Just for fun, I propose call this ROIRWD and, furthermore, that we agree henceforth to pronounce it “roy-ward”.)

Now, of course the lack of empirical evidence for a thing’s existence doesn’t mean the thing doesn’t exist, and anecdotal data isn’t without its value. But it sure is helpful, when articulating the business case for a new and often more expensive approach, to have some proof that said approach is worth the cost. So I was delighted when, on Monday, developer luminary, respected author, and Polar co-founder Luke Wroblewski posted the tiny grenade below to his blog. It’s a tiny data set, but it contains some astonishing numbers. (Skinny Ties: 377.6% revenue growth on iPhone? Like a boss, as my kids say.) So I’m reposting the data from that post here, along with his plea, verbatim.

Wait… that’s only four sources of data? Sadly, I don’t have other public numbers right now as most organizations don’t share their data. If you’ve had success with a responsive design, my plea to you is to please share what you’ve learned. The more we can learn from each other, the better we can all get.


Luke’s blog is surely more widely read than ours, and strictly speaking, he probably doesn’t need this particular signal-boost. But his plea should be echoed by as many of us as possible, for other data such as his are surely out there and one of the best things we can do for our clients and our craft is to share as liberally as we can.

Do you have data you can share that illuminates the ROIRWD question? If so, please let us, and the world, know.
