Techniques are described for improving language translation of content (e.g., web content) on computing devices (e.g., mobile computing devices). For example, automatic translation can be performed when entering reading view in association with displayed web content by determining that the displayed web content is not in a language that is understood by the user (e.g., as indicated by language settings). As another example, language-related meta-data can be passed between applications and used in language detection of content, such as web content.
