of advertisements are thus not constant. Externally, the position an ad is displayed is termed “Ad
Rank.”

After the auction is completed, Google calculates the price an advertiser will pay
for the display of its ad if actually clicked on by the user. Advertisers are charged on a per-click
basis: if the ad is not clicked on, then Google does not receive any money. (“Ad System
Overview,” G-IPE-0009737.)
This price
is termed “actual cost per click,” “Actual CPC,” or simply “CPC.” As would be expected, the
CPC for any ad in any given auction will not exceed its Max CPC. (See, generally, “Life of a
Dollar,” G-IPE-0008851 to G-IPE-0008854; “Ad System Overview,” G-IPE-0009737.)

Google uses a sophisticated machine learning algorithm termed the “Smart Ad
Selection System” or Smart Ads to compute predicted clickthrough rates. (See, e.g., “Smart Ad
Selection System (SmartASS™),” G-IPE-0002076 to G-IPE-0002080.)

Load Balancing
A user’s incoming search query is first received by Google’s load balancing
system, which determines which Google web servers should receive and process the query. This
ensures that each search request is routed to a web server with available resources, reducing the
chance that the user request will “hang” or take overly long. One can think of load balancing as
similar to an employee at a grocery store that directs shoppers to the cashier with shortest
checkout line… in a store with thousands of cashiers and millions of customers. (“The Life of a
Query,” G-IPE-0004739-40).
