eli5: How can Google maps know many small and recent businesses’ locations so accurately?

Question

I’ve realised that most businesses (even small kiosks) are seen on Google maps. Where and how do they get that information?

Answer 1

Companies are allowed to put their location on Google. Maybe even individuals. Some do good enough job themselves, some don’t and then people (like me) go out and usually fix their location if it’s incorrect, hours, add photos, web pages etc. And we get to see how many people have seen our changes/photos.
