Everyone is familiar with 2015’s Mobilegeddon and it looks like there will be a decent shakeup in 2016 as well. On March 16th Google announced that they will be rolling out a change to mobile search results that increases the negative effect of having a website that is not mobile friendly. Mobilegeddon smashed traffic to some sites that weren’t mobile friendly, but a lot of sites that weren’t mobile friendly remained in the results. This update will cut more websites out of the mobile results that are not mobile friendly. If your site isn’t mobile friendly by now, what have you been doing?
Last year, we started using mobile-friendliness as a ranking signal on mobile searches. Today we’re announcing that beginning in May, we’ll start rolling out an update to mobile search results that increases the effect of the ranking signal to help our users find even more pages that are relevant and mobile-friendly. – Google Webmaster Central Blog, March 16th, 2015.
When Google announces something, they don’t mess around. You’ve got a month to fix your non-mobile friendly site before it’s gone. I expect this round of cuts to be fairly significant.
