Google’s mobile-friendly algorithm update, dubbed ‘mobilegeddon’ by the media, has been in effect for almost six months. And there is little doubt that in the run-up to its initial launch back in April, there was a lot of concern regarding the degree to which it would have a negative impact on the search engine optimisation efforts of millions of businesses. This algorithm has just received its most recent update, with Google rolling out an updated version on November 2nd. And there is still much debate around its positive and negative aspects, as well as over the extent to which its impact has lived up to the hype. So what is mobilegeddon, how has its impact been felt and did it really deserve to be seen as such a cause for concern?
