:**Using "America" to refer to the US isn't incorrect, but it is ambiguous out of context. When people search for "America" we have no way of knowing what the context is, or indeed if there is any, therefore we need to determine whether one particular use of the word "America" out of context is used more often than all the other uses combined. Every single bit of evidence given here shows that most people are looking for something other than the United States when searching for "America" out of context. It is therefor clear to those who understand what primary topic means that there is no primary topic or the term "America" used out of context. What the usage is when context is known is entirely irrelevant.
