The Effects of Google’s Mobile Friendly Algorithm Change Post #Mobilegeddon

May 22, 2015 by veezy Leave a Comment

The following data comprises various types of sites and pages. Based on the data and variability I’ve seen, the effects of any site will have a lot to do with the ratio of competitors for those keywords and how many of them are mobile friendly. For more competitive keywords, I would expect there to be a lot less movement, especially on page 1. For less competitive keywords, I would expect there to be significantly more movement, particularly past page 1.

A couple things to note:

  1. As more sites and pages become mobile friendly, this factor starts to cancel itself out – unless they change the signals and the 1|0 nature of the current algo.
  2. It will also be more difficult to measure over time until the mobile growth rate starts to plateau, especially vs the desktop growth rate. Year over year comparisons of a mobile friendly algorithm will be near impossible unless you’re tracking rankings of desktop vs mobile.

All data compares the 3 weeks before after the mobile algo launch week – and therefore excluding – 4/20-4/26 to account for the week-long rollout. All data is for Organic Google traffic only.
