This is probably a stupid question and i think i know the answer but just wanna check. If i had a keyword say for example "keyboards" and i enter that into adwords keyword tool and click "Only show ideas closely related to my search terms" and export all the keywords as a text file. Each phrase would have my exact keyword in it, so is this a great example of keyword diversity???

Obviously i would add generic keywords as well, but in theory, my main keyword would never appear twice on its own as just "keyboard", it would always have different words around it. like acer keyboard, keyboard acer etc
