Relativity really is key here. Nick Flame inspired me to do domain parking. And for the past 2-3 weeks I have been following his words to the T. Except I forgot to set a master keyword for my sites. Let me tell you....WOW. I went from 12%CTR up to 47% and am making three times the money than before, just because I changed one little setting on sedo.com. Please, don't make this mistake, you will pay dearly for it.
