In order to appear on the search engine result page, your content needs to match what people search for on Google. It's called search intent. If someone searches for "keto diet for pregnant women" and if you have an article that uses exactly the same search phrase on the title and body, it will satisfy the search intent and will appear on the search engine result page. It is very important that you identify search engines for building sustainable traffic to your website through search engines. Therefore, you need to identify search intent, use keywords that align with the search intent, and create content that answers their questions.
