Ringtone keyword experiment – 1000+ clicks

Well, I am testing several keywords everyday lately.  I decide to run Paris Hilton yesterday because she was on the news every hour.  Guess what, I got 1200+ Clicks from Paris Hilton Ringtone.  Conversion – Nada..$2 from adsense.  Well, I just lost $120 and YSM remove keywords because according to YSM, my site avg. ranked was 2.3 for that keyword.  Imagine 1200+ clicks with 10% coversion when you get right keywords at right time..well I got to think carefully for next keywords.
