Responsive design or responsive website design, or short RWD, adjusts websites to the display formats of desktops, tablets, phablets and smartphones by moving, reducing, enlarging or re-structuring content.
This is increasingly important, as the proportion of search queries from mobile devices is on the rise.
Thanks to responsive design, the crawlers of the search engines no longer need to differentiate between URLs for stationary and mobile devices. For the Googlebots, for instance, it would theoretically be possible to index the pages of a website and to cache it.
Crispy Tip: Responsive website design benefits SEO and is a must-have for each and every company, particularly in e-commerce.
