“People want to do different things on
mobile, so one adaptive experience is a bad
idea.”

“Responsive Web Design produces bad
performance.”
http://bit.ly/Uh5czr

“Responsive sites/apps require more code
and more testing.”

By 2015, there will be one mobile phone for
every person on Earth.
Google Internal Data

More than half your customers won‟t
recommend your business to a friend if you
have a bad mobile site.

When someone searches and finds your
mobile site:
• 61% of them will call you
• 59% will visit you
• 70% of mobile users compare prices
• 65% read product reviews
• 50% of mobile searches have lead to
purchases

this is just the tip of the iceberg

Responsive Web Design is not mobile design

Responsive Web Design does not have to
take more time, or cost more money

Responsive Web Design is worth it

“Responsive Web Design rocks. It‟s like
Motörhead playing „Ace of Spades‟ at
Stonehenge…on an asteroid.”
