Multiple Languages
Many sites have pages in more than one language, and we see some correlation in the number of languages and the installation of search engines. A large majority (65%) of single-language sites did not have a search engine installed. A small majority of sites with two languages did not have search, and of sites with three or more languages, 54% have search installed. This indicates that as the sites become more complex and wide-ranging, search engines become more important for locating information.
This survey does not cover the issues of language and character code recognition, which are particularly difficult in multilingual sites, nor did we ask about the complex problem of cross-language searching.
