I-mode service links to nine search engines, just not Google or Yahoo Users of NTT DoCoMo Inc.’s I-mode service should be able to find a wider variety of mobile content after the carrier said it linked its service to nine domestic search engines.Users who run keyword searches from their phone on the I-mode main page will be presented with results from NTT DoCoMo’s service, which covers only official I-mode sites, and also links to the nine search engines that produce results from unofficial sites. Official sites are those that have tied up with NTT DoCoMo and are listed on the carrier’s main menu screen.The nine search engines include Microsoft Corp.’s MSN, Rakuten Inc.’s Infoseek Mobile, Livedoor Co. Ltd.’s Livedoor Mobile, NTT Resonant Inc.’s Goo and several smaller services. Absent from the list are Yahoo Inc. and Google Inc. Yahoo has a relationship with Softbank Corp., which earlier this year bought NTT DoCoMo-competitor Vodafone Japan, and Google has already announced a tie-up with KDDI Corp., which runs the Au mobile phone service.As the number of sites and amount of information available on the mobile Internet increases, carriers are looking more closely at mobile search. Since Vodafone was acquired by Softbank, the top page of Vodafone Live in Japan has carried a prominent link to Yahoo Japan. The Google deal with KDDI calls for a Google search box to appear on the top page of KDDI’s EZWeb service. Technology IndustrySoftware DevelopmentSmall and Medium Business
