Market brief: the shift to AI search
Buyers now start with AI, and most brands are not in the answer
How buyers find products changed overnight. AI assistants are now where many buyers start, before they visit a search engine, let alone a brand site. Traditional search traffic is falling, and the window to claim your category in AI answers is getting narrower. Most brands are still running the old playbook.

Product discovery moved from ten blue links to one synthesised answer
Buyers used to click links and choose. Now they ask AI and get a direct recommendation. The query gets longer and more personal, the result collapses to a single answer, and the brand surface shrinks from a listing to a mention inside that answer.
| Dimension | Yesterday: link-based search | Today: AI answer engines |
|---|---|---|
| Query format | "best running shoes" | "What running shoe should I buy?" |
| Result type | 10 blue links | Synthesised answer with citations |
| Brand surface | Title tag and meta description | Cited entity in AI response |
| Traffic type | Click to site visit | Zero-click or direct intent link |
| Attribution | Last-click, cookie-based | Prompt-level, first-party |
| AI involvement | Ranking algorithm only | Full synthesis and recommendation |
What this means for brands. Being in that recommendation is the new share of voice. A brand that is not named in the answer has no listing to fall back on.

AI models pull retail citations from Reddit more than from brand sites
AI models don't crawl your site in real time. They rely on content patterns they've learned from high-signal sources. Reddit supplies 30% of retail citations, ahead of official brand pages at 24%. YouTube and Amazon add another 31% between them.

What this means for brands. Your brand needs to be present where AI looks first. For most retail categories that means community threads, video and marketplace reviews, not only your own pages.

Four platforms now answer product queries, and each one cites brands differently
These are the channels where AI now answers product queries, and where your brand can be cited. They differ in scale and in how a brand gets surfaced: a citation in an answer, a featured position, or a sponsored placement inside a shopping session.
| Platform | Monthly users | Integration | Opportunity |
|---|---|---|---|
| ChatGPT | 400M+ | Answer citation and purchase intent | Product recommendation, brand authority |
| Perplexity | 100M+ | Product recommendation layer | Category-level SOV, direct citation |
| Google AI Overviews | 1B+ | Featured answer position | Zero-click brand visibility |
| Retail AI engines | Multi-billion sessions | Sponsored agentic placement | In-session product discovery |
What this means for brands. Visibility on one platform says little about the others. Measure each engine on its own before deciding where to spend.
