With AdWords you might assume that the highest/first position is the most desirable place for your ads to be, but actually, what’s really important is taking control of your ad position. In AdWords, controlling your position and your bids is more important than your ad being listed first. The reason for this is that you need to find the position (and the bidding price) that is most advantageous for you, otherwise always aiming for the highest position could mean unnecessarily wasting a big chunk of your budget.
