So much lulz on this thread.
Responsive design doesn't mean anything to Google when ranking your site. You could even argue that the added bloat of all extra css and media calls / work arounds (Responsive design is a complete coding clusterf^%k IMHO!!!) does more harm than good. (Not tested this theory just IMHO)
Some of my easiest ranks have been solid, well formed static html sites. No Disneyland, SASS or that stupid Laravel Artisan nonsense just plain old html / css.
Keep it simple, use analytics and only give em responsive if you get alot of mobile hits, otherwise keep it basic! In some industries like one I work in mobile traffic doesn't even convert so test the bottom line too, no point in giving people a nice user experience if they aren't even going to buy from you!
No one ever made extra cash in IM by giving themselves more complicated work to do! Keep it simple, get it working and on to the next thing! Don't fall into the "web designer trap" of making everything pretty. Pretty doesn't pay the bills!
