Aggressive "answer" boxes. So you search for a question, and Google provides not just necessarily a featured snippet, which can earn you a click-through, but a box that truly answers the searcher's question, that comes directly from Google themselves, or a set of card-style results that provides a list of all the things that the person might be looking for.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
