There are a number of rating sites out there, sometimes with conflicting information. What do you go to when you want to donate, especially when you want to look for a particular issue/crisis/disaster.
If I can improve my impact by taking a few minutes to research, it would be nice to have a place to go instead of googling “charity rating for ____”
Charity Navigator is a good place to start identifying options based on your interests. I don’t think their “ratings” are great, but I discovered a nonprofit I never knew about through them.
