how does google know how busy a place is

You may have wondered “How Google knows how busy a location is?” you’re not alone. This is the first time that I have heard about this phenomenon. However, it’s something I find very interesting and wish I could stop blame Google. It’s true that Google is not entirely responsible for a place’s popularity, and it can sometimes be overestimated. However, there are some ways to make your life easier by knowing how busy it is – and when you should avoid it.
