After six months of preparation, the Google Speed Update is now rolling out. It only impacts the mobile search rankings of the slowest of sites on the internet.
Google has updated its original blog post around the Speed Update saying this is now “rolling out for all users.” Google this morning has begun incorporating the new Speed Update algorithm in the mobile search results as a search ranking factor.
We posted detailed FAQs on new Google Speed Update a while back explaining some of the more common questions around the speed update. And as we clarified last week, this update only impacts the slowest of sites on the internet.
Google’s original announcement said this will “only affect a small percentage of queries.”
Ryan’s Take 
2018 has seen Google take mobile optimizations for its search engine to the next level. The mobile-indexing first initiative that Google implemented earlier this year prioritizes the mobile version of a web page over that of a desktop version. For websites that have a responsive design this shouldn’t make that much of a difference. The speed update, on the other hand, could impact websites that have neglected page load times in a big way.
Google has always advised webmasters to have the pages load as quickly as possible. Now they are backing up that assertion by factoring speed into their ranking algorithm. If you ask me, it’s about time! Why should a poorly optimized website have the ability to dominate keyword rankings? What good is SEO, if the content isn’t delivered in a reasonable amount of time?
If you already have a fast website, you probably won’t see much of a change in your rankings if you can squeeze an additional few points to your PageSpeed score. Conversely, websites which perform horribly could see a nice boost in the SERPs if they can manage to get their loading times down significantly. What wouldn’t surprise me is if Google starts to prefer AMP (accelerated mobile pages) over non-AMP pages in the search results. Would two equal mobile pages get the same treatment if one were AMP and the other wasn’t? Logic says that AMP would take priority. The question is how much weight would AMP have over other factors.
