Duplicate Keyword Question

Does Yahoo treat "ringtone", "ring tone" and "ringtones" as the same thing? Also what about phrases like "cingular ringtones" and "ringtones cingular" do they treat that as the same thing?

I'm really getting pissed off because I don't understand why a lot of my keyword phrases are coming up as duplicates!

 

keywords with trademark names in them, like cingular, will not pass editorial review.

 

oh? thats interesting then....
