When creating your page titles, make sure the language and script of the title element correspond exactly to the primary language and script used in the page content. Avoid mixing languages or scripts within the title, such as appending an English translation to a title written in another language or using transliteration instead of the native script. Google’s algorithms detect these mismatches and may replace the title shown in search results with one that better matches the page’s main language and script. This practice helps maintain consistency and improves how your page is represented in search results. [Google]
