Here 's how this experiment was actually conducted . I took 25 pages of different sizes ( from 45 KB to 4151 KB ) and inserted unique , non - existent keywords into each page at 10 KB intervals ( that is , a unique keyword was included after each 10 KB of text ) . These keywords were auto - generated exclusively for this experiment and served as " indexation depth marks " .
