During the Q&A portion of a John Mueller hangout, one webmaster asked about question-oriented titles and the best way to optimize for them.
Because of the vagueness of the question, John was not 100 percent sure regarding what the webmaster was going for.
But he explained that you should not use exact-match questions in your page titles. Questions can change very quickly, and you don’t want to lose traffic because your question changed.
Make sure you know what your users are searching for and that you address the intent behind the query.
It’s up to you if you want to match the query one-to-one, but be aware that you could end up losing traffic later when the query shifts.
