Is grammar important when selecting keywords?
When searching for keywords I see a lot of them that appear on Google dropdown menus that are not grammatically correct but which seem to have some good stats associated with them. I'm guessing that this is due to searches by people who do not necessarily have English as a first language or those of us (me included) who sometimes just type in the really important words in the search box so often miss out pronouns or definitive pronouns such as 'a' or 'the'. Are these ok to use as keywords if they are not perfect English? What do people think?
