The ethics of people using search engines, what they want is the answer, and it becomes the job search engine to provide answers. Like people reading a blog post, viewing an infographic, or watching a video, they want answers to gain knowledge. One important tip for you, people not only want answers, but they want answers quickly. So make your content easy to read so that people can. Try reading titles or subtitles from non fiction books or articles. Readers will be made to wonder or feel curious. It is the author's job to provide answers and present supporting information. thank you
