Discovery is fragmenting off Google. The share of product research starting on TikTok, Instagram, YouTube, and Pinterest has grown every year since 2022, and 2026 is the year most B2C brands should treat social search as a first-class SEO channel.
Headline numbers
- ~40% of Gen Z start product research on TikTok or Instagram (multiple published sources, 2023–2025).
- ~70% of Pinterest searches are unbranded — pure category intent.
- YouTube is the second-largest search engine in the world; its shorts search inventory is under-competed relative to long-form.
- LinkedIn search volume for B2B category terms has grown quarter-over-quarter for two years.
What's changed on the platforms
TikTok surfaces suggested searches in comment threads. Instagram indexes reel audio and on-screen text. YouTube added chapters as a first-class ranking input. Pinterest rebuilt its search results around visual and text intent together.
What that means for a 2026 plan
- Budget for search-first content on at least two platforms.
- Report Share-of-Discovery per keyword panel per platform, monthly.
- Treat profiles and bios as landing pages, not decoration.
