Could it be true that a high (750) number of keywords in an MSN adgroup might lower some kind of Quality Score and/or raise CPC if many of the KW are not showing a high CTR? I have a lot of mispelled keywords and so on - should I be removing them? I got the impression from a rep today that too many non-performing KW was a bad thing and would cause a problem.
