So guys, while playing with KeywordToolExternal I discovered a three tailed keyword. It's the first one on the list on the image attached below. Will it be a successful keyword if we consider the global monthly search volume ? If I register the com domain (which is unregistered) and build a blog for example , will I have success? I'm asking cos I'm a bit confused on how someone can understand if a short-tailed or long-tailed keyword is considered a "gold keyword"
