Re: Keyword Effectiveness- KEI
That looks good but I wonder if it illustrates the real situation. It's like a job vacancy. Suppose there are 10 vacant positions and 100 people apply for the jobs. Is the possibility we are hired 10/100 or 0.1? Do we need to beat 9 other applicant to get hired? No. We need to be better than at least 90 other applicants.
