An FAQ on your website is important because it helps to provide visitors with quick answers to their questions, which can help to reduce customer service inquiries. An FAQ can also help to improve your website's search engine optimization by providing content that is relevant to your products or services.

The questions in your FAQ should be related to the products or services you are offering. Common questions may include information about pricing, product specifications, shipping, returns, customer service, and other helpful information. It's also important to include questions about topics related to your industry so that visitors can quickly find answers to their questions without having to search for them elsewhere.
