Upgrading content with quizzes for engagement and SEO

Have you tried, or are you thinking of adding interactive quizzes to your blog posts for engagement and SEO? Did it work for you, or do you think it would work for SEO? Is there anything preventing you from adding quizzes? Do you know any Wordpress plugins or 3rd-party services that integrate with Wordpress? (I would rather not create all the quizzes manually)
