What about  Chjoom FAQpage ?

From JED

Displaying Frequently Asked Questions on a website is always useful. You can easily draw attention to your content if it is structured in a Q&A. People tend to spend less and less time on a website so aggregating information to them with questions can build trust and serve their needs.
As a matter of fact you can increase your Joomla SEO via signaling FAQPage schema type to the search engines. In addition in some cases it might appear on the Search Engine Result Page (SERP).
With this lightweight module you can place this FAQ into any module position or with loadmodule or loadposition syntax into any article/category page or even into a Virtuemart product page.
