What is common with all the top running websites in the world is they pay extra attention to customer support and user experience. FAQs is an excellent way of not just engaging the visitor on your Joomla site but also feeding them with information that could be generic or product based. This way you not just clear the most frequently asked questions but also doubts or friction on the conversion path. Moreover, FAQs are one of the prime sources to get featured on Google snippets.
