The American Customer Satisfaction Index project seeks to measure an elusive thing — how “satisfied” are we with the companies that rule our lives? Google has dominated the ratings for a long while. The ACSI asks people to measure companies across a range of factors, and then it compiles the results into a 100-points scale; in 2002, Google’s first year in the survey, the company won 80 points — and since then, until now, it’s hovered above that very fine mark. As Greg Sterling points out in Search Engine Land, though, in the latest ACSI survey Google posted only a 78, and for the first time its rival Yahoo outranked it, winning 79 points.
