Goggles are search filters using which you can prioritize, degrade, or even block domains in PriEco
They are open source, publicly hosted in a Git repository or freely online
Here you can find known Goggles you can apply to your searches
While using PriEco you can create your own Goggles or modify known ones just for you
Credit to Brave search for creating them
PriEco adopted their standard so that your Goggles are cross compatible
