I think I am not the expert here,anyway,what is the paid to placement is,is this meant-advertiser should buy "some cash for certain keyword position finding sort of"is this?or it is something else? and if I can make comment I think google adword and
seo do not charge pay per placement stuff,and this what made Google so competitive and strong that No one got "privileges when they got better investment"so for me,I dont think pay per placement is great idea.I think "scoring per "relevancy"should be the number consideration whether blogger/marketer should be put higher or lower
