SEOV is the value of traffic the #1 ranking site supposedly get. The actual value is different on a niche by niche basis. There are different school of thoughts regarding what percentage of the traffic do the #1 ranking site gets. Some says 42%, some says 50%. Do you think it's even necessary in a KW tool? Would 50% be good to use? SEOV = Search Count * Avg CPC * 50% Appreciate the feedback.
