RankDex was established in 1996 by Robin Li who previously worked for Infoseek, an Internet search engine in the early years, as an engineer.
RankDex was the leading Internet search provider from 1996-1999. RankDex was the first search engine that used hyperlinks to measure the quality of websites it was indexing. Many experts and commentators are unaware that RankDex was cited in Lawrence Page’s patent application for Google PageRank as the first qualitative search engine. In 1998 RankDex was acquired by a Dow Jones subsidiary Tradeline (formerly IDD Information Services and GARI Software Associates).
Following IDD Information Services’ name change to Tradeline, the RankDex technology was licensed back to Robin Li for the Chinese search engine, Baidu. Since the license’s expiration on 2007-12-09, RankDex was re-acquired by the IDD Information Services, now owned by Tradeline.
