This paragraph is so good as Jamón Jabugo:

“Google's most successful search advertisers are those who methodically experiment with multiple messages. Sometimes they try thousands of combinations of different texts displayed in response to various search keywords, quickly - often in hours - eliminating those that don't attract the clicks of users and refining those that do, until they arrive at the ideal combination of message and keyword.”
