The rules

Sitespeed.io score are based on the rules. Click here to see a detailed version of the summary. The rules are simple: Green color means you don't need to do anything (of course there could still be things you can do to get better performance). Yellow tells you that you should look into this, and guess what, red means that something is really bad. The blue color are things for your information, no rules but things that will be good to know.
