The first step is already taken if you are adding a search engine to your website but you can take steps like modifying your keywords to accommodate long-tail and conversational keywords through analytics from your search engine. Also, you will need to modify the content on your website to accommodate conversation data and add a new and strong FAQ page. Improving your website structure where you can add plugins to identify sections within your webpage suitable for conversion from text to speech is also a great idea. Also, it is best to keep the data on your website simple and easy because everyone is not using high-end vocabulary to make routine searches.
