Google rolled out an update called Mobile-First index to focus on mobile search.
Does this Algorithm change require from website not only being optimized with a simple responsive design, but also using responsive design applying Mobile-First CSS approach (as opposed to using Desktop First) ?
1. Mobile first CSS is much efficient IF Google made a decision to focus on Mobile search.
2. In Desktop First CSS you always overriding a lot of CSS (lots of processes = higher latency = slower mobile version. Therefore, I assume that it would be wise to take the Mobile First CSS approach, but I am still not 100% sure.
