Languages used on the Internet

There is debate over the most-used languages on the Internet. A 2009 UNESCO report monitoring the languages of websites for 12 years, from 1996 to 2008, found a steady year-on-year decline in the percentage of webpages in English, from 75 percent in 1998 to 45 percent in 2005.[2] The authors found that English remained at 45 percent of content for 2005 to the end of the study but believe this was due to the bias of search engines indexing more English-language content rather than a true stabilization of the percentage of content in English on the World Wide Web.[2]

The number of non-English web pages is rapidly expanding. The use of English online increased by around 281 percent from 2001 to 2011, a lower rate of growth than that of Spanish (743 percent), Chinese (1,277 percent), Russian (1,826 percent) or Arabic (2,501 percent) over the same period.[4]

According to a 2000 study, the international auxiliary language Esperanto ranked 40 out of all languages in search engine queries, also ranking 27 out of all languages that rely on the Latin script.[5]

W3Techs estimated percentages of the top 10 million websites on the World Wide Web using various content languages as of January 31, 2021:[1]

All other languages are used in less than 0.1% of websites. Even including all languages, percentages may not sum to 100% because some websites contain multiple content languages.

The figures from the W3Techs study are based on the one million most visited websites (i.e., approximately 0.27 percent of all websites according to December 2011 figures) as ranked by Alexa.com, and language is identified using only the home page of the sites in most cases (e.g., all of Wikipedia is based on the language detection of http://www.wikipedia.org).[6] As a consequence, the figures show a significantly higher percentage for many languages (especially for English) as compared to the figures for all websites.[7] The figures for all websites are unknown, but some sources estimate below 50 percent for English; see for instance, Towards a multilingual cyberspace[8] and the 2009 UNESCO report.[2]
