The demand shift is real, so start with the numbers instead of the slogan.

Adobe's February 2026 survey found 49 percent of US consumers have used TikTok as a search engine, up from 41 percent in 2024, with 65 percent of Gen Z doing so. The same study puts Reddit at 38 percent usefulness among Gen Z, and 14 percent of consumers now say they are more likely to use ChatGPT than Google.

Meanwhile the classic result page keeps less for everyone. Zero-click searches hit 58.5 percent in the US in Q1 2026, and the AI layer pulls from these platforms directly: one citation analysis puts YouTube at 23.3 percent of AI Overview citations, with Reddit and Wikipedia close behind.

So yes, discovery fragmented. Whether that makes SEvO "the new SEO" is a different question, and the honest answer is no. It is the new demand map, served by the same discipline.

Two corrections keep the strategy sane.

First, the platforms are not interchangeable. The 2026 data shows Gen Z's preference for TikTok over Google actually fell, from 8 to 4 percent, because people use TikTok for visual, discovery-type searches and Google for factual and transactional ones. Copying the same message everywhere optimizes for a customer journey that does not exist.

Second, the surfaces feed each other. AI assistants synthesize answers from YouTube transcripts, Reddit threads and review platforms, which is why UGC platforms dominate LLM citations. A Reddit thread praising you is simultaneously social proof, a ranking asset and AI training material. That is one investment paying three surfaces, and it is why third-party presence beats owned content in AI answers.

The unifying layer underneath all of it is the entity. Every platform and every model resolves you to the same question: who is this brand, what does it sell, what do others say about it. Consistent naming, identifiers and corroboration, the entity work SEO already knew, is what makes visibility on one surface transfer to the others.

A practical allocation for a small ecommerce team, since nobody can do six platforms well.

Keep the site and blog as the canonical source, because that is what the models read to learn who you are and where every surface eventually links. Add one video surface if your product demonstrates well, since demonstration content is what AI answers increasingly pull for how-to queries. Earn presence on the community surface where your category is discussed, through participation and reviews rather than posting ads into forums.

Then repurpose rather than recreate: one deep guide becomes the video script, the thread answer, and the passage an AI quotes. Format changes; the entity and the claims stay identical.

What to refuse: separate agencies for GEO, TikTok SEO and Reddit SEO selling the same fundamentals three times. The evidence on what earns AI visibility is the same list that earns snippets and social discovery: specific, fresh, verifiable, corroborated.

The straight verdict: search everywhere is an accurate description of where your customers are. As a discipline, it is SEO with more distribution surfaces and the same center of gravity. Master the entity and the content once, then syndicate the proof everywhere it counts.
