A bar chart showing the click-through rate for search results from the Google search engine. The horizontal axis is the ranking of pages with the first result on the left. Ranks 1 to 5 are listed individually, followed by a single column for results 6 to 10, then one column apiece for the second and third pages of results. The percentage click through rate is shown on the vertical axis and ranges from 0 to 40 per cent. The graph shows a sharp decrease in the number of people clicking on each link with increasing rank. The first link has a click-through rate of 31%, the second receives 14% of clicks, the third about 10%, the fourth link receives 7% and the fifth 5.5%. Results six to ten receive 3.7% of clicks. The second page of results gets 4% of clicks and the third page only 1.6%.
