ok, here's a concrete example
say I'm showing SERPs for "scuba"
I have a list of words that are *related* to it, like these:
actually, that list is 500+ words long.
When I do a similar query for any common english noun, I get the same kind of thesaurus barf. The keyword list includes misspellings, foreign spellings, and questionable phrases...
What I'd like is to show a list more like this:
It's not *crucial* that the highest bidded terms be at the top. But it would be nice to take say the top 15 keywords sorted by bid price, so all the chaff is discarded.
#2 sounds like a great candidate for this kind of weeding
#3 is appealing too
