Yahoo and Mobile Search

Russell Buckley has an interesting post about the Barcelona Mobile Monday and the talk given by Ricardo Baeza-Yates Director of Yahoo! Research Barcelona.
“When Ricardo moved on to talk about the difference between search on a mobile and search on a PC, there were a few surprising differences. Search on mobile uses more words, despite the comparative difficulty of inputting. I’d guess that this is down to the user wanting to be as accurate as possible, first time, rather than subsequently wanting to refine things…The other idiosyncrasy of mobile search is that there’s more variety in the queries submitted. I can’t remember the exact figure (does anyone know?) but it was something like for PC search, the top 20 queries account for about 50% of searches, whereas in mobile, the top 20 are only 2%.”
