Why is Search Engine Positioning so important?
    – 70% of the clicks are on web sites from positions 1 thru 10 (on page one)
    – 25% of the clicks come from positions 11 to 30 (on page two)
    – 95% of the total clicks come from positions 1 to 30 (on page one or two)

That means, if you are not listed on pages 1 or 2, you are simply "out of luck".
If they cannot see you, there is NO OPPORTUNITY to sell.
