The change though is not all good Brand advertisers trying to use search may find it is more expensive and advertisers trying to promote things on irrelevant keywords will have challenges.
Perhaps characterizing at irrelevant keywords dilutes my point. If I'm Snickers, I might want to run on the keyword "Kiss" because of my Superbowl commercial. Branding Snickers with the kiss. My initial cost will be exceptional relative to kiss brands (like the band kiss or maybe hershey's kiss) because I have no relevance to that term. Over time, sure, my link may be popular driving up my quality and lowering my costs but as an advertiser, what if that doesn't happen? I still want to brand myself with that term and shouldn't have to pay through the nose to do that. Another more realistic example. I manufacture cars, albiet poor quality cars, say the old Nova. I want to advertise keywords like cars, auto, automobile. I am highly relevant to those searches yet, because of my relative brand weakness, I'm penalized and have to pay more than what BMW, Ford, or Toyota might have to spend. This theory argues that it favors the big, established brands while penalizing the little guy (or big guy with poor brand recognition) Don't get me wrong, I'm just arguing a counterpoint to the argument that the change is all good. Perhaps making it more expensive for new brands is the right move.
