5. A Google AdWords auction is a tool that Google uses to determine the cost per
click(CPC) amount that is required of an advertiser to pay when users click their
ads.
When bidding for a keyword, your cost per click and ad position is relative to the
quality score and maximum bid of competing bidders. The actual position of your
ad is determined by your ad rank (Maximum bid times quality score) as the
highest ad rank gets the 1st ad position. Your actual CPC will be determined by the
ad rank of the next highest ad below you divided by your quality score. The only
exception of this rule is when you are the only bidder or the lowest bid in the
AdWords auction - you pay your maximum bid per click! AdWords bidding
heavily penalizes advertisers who bid with low quality scores.
The auction gets run billions of times each month. The results are such that users
find ads that are relevant to what they're looking for, advertisers connect with
potential customers at lowest possible prices and Google rakes in billions of
dollars in revenue.
