Izzi Smith presented on winning featured snippets by focusing on informational-transactional queries, providing structured content that solves user problems, and using schema markup to create rich snippets. She discussed a case study where Sixt improved brand awareness and conversions by developing rich snippets for car model pages that included additional content and car data with schema. Another example showed promoting structured answers to their own landing pages increased the featured snippet rate and click-through rate. The key takeaways are to understand user intent, create helpful content through problem and solution research, and make information easily understandable and shareable.
