How quickly your site loads can have an impact on your rankings in Google.
 
You might be familiar with the Google PageSpeed Insights tool that helps you understand the speed score Google has given each URL of your site.
 
Google is trying to make this tool easier for us to use and understand and has launched an initiative called "Core Vitals".
 
They have published an article about these Core Vitals and inside that article are links to additional information that can help you understand how to improve your site speed scores.
 
Heads up - it's not easy information to digest if you're not very technically minded.
