The web is no longer dominated by English speakers: only about 1-in-4 Internet users speak English. Even native-English speaking countries have substantial populations that are more comfortable communicating in a different language. And some websites are required by law to provide information in alternate languages.
There are two types of multilingual content: web sites geolocated to a specific country and web content that has been translated for non-native speakers.
