Using questions in your articles can be useful, as it may help you with voice search and it may help you with obtaining a featured snippet on SERP.

Using questions in your content is a highly effective strategy for several reasons. For voice search, people naturally phrase their queries as questions (e.g., "What is content marketing?"), so including these questions and their direct answers in your articles increases the likelihood of your content being matched and read aloud by voice assistants. Similarly, search engines often pull concise, direct answers to common questions to display as featured snippets at the top of search results pages (SERP). By structuring your content with clear questions and immediate, authoritative answers, you optimize your chances of securing these valuable, high-visibility positions.
