I am confused about Google Keyword Tool
2) I don't seem to see any difference among the Broad, Exact and Phrase Match when selecting anyone of them. Seems to me that the only thing that matters is whether the "All Keyword Ideas" or "Ideas Containing My Search Terms" is checked which will yield different results
3) What happens when I select more than one Match Type at the same time?
