Although Google has stated that there is currently no direct relationship between loading and positioning times, if your site is very, very slow, it risks being penalized in the search results compared to the quicker.
Slow Google websites dedicate a smaller crawl budget or less resources, so optimizing in this sense can lead in some cases to an increase in indexed pages and more frequent updates. You can use a simple tool that checks the site and shows us how to improve performance as part of Integrated Marketing Communications.
Page Speed Insights is a tool that automatically checks a series of characteristics that affect speed. It has been developed and is frequently updated on the basis of best practices known and published by developers in the various communities of the web, and also on the basis of studies by a Google team.
