What does your search engine say about you? Well, if you believe a new study from a group of marketing agencies, it says a lot. A group that included Wunderman, BrandAsset Consulting, Zaaz, and Compete set out to learn about the shopping habits and brand preferences of search users. Google users tend towards Target and Amazon, while Bing users (despite apparently being "early adopters") are more likely to go to Walmart. Oddest of all, Yahoo! users showed a "strong preference" for Sprint and AT&T over Verizon or T-Mobile.
