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

Either the business entered itself onto Google Maps, or the info is found by Google’s “web crawlers” or “spiders” – bots that scour the web for new information to index on their search engine.
