Bing, Microsoft Corp.’s search engine, today is launching a national campaign to highlight Bing’s commitment to honest search results and to help explain to consumers the risks of Google Shopping’s newly announced “pay-to-rank” practice, in which the shopping search results customers see are not true search results such as they see elsewhere on Google; they are actually ads that are ranked, in part, by who pays the most.
