Google announced a new “algorithmic improvement” in how it selects titles for search result snippets for multi-language or transliterated titles. This will also help when the title element is written in a different language or script than the content.
This algorithm change is based on the general idea that the title of a document should be written in the same language or script as its core contents, according to Google.
When the title is written in a different language or script than the content, Google says it will try to determine the optimal title link for the search result snippet.
