From search to conversation: how LLMs are changing the way we buy.

The way we buy has changed, not gradually, but radically. And the catalyst? Not another eCommerce platform or social network, but something far more fundamental: Large Language Models (LLMs).

Tools like ChatGPT, Claude, and Gemini are not just shaping how we ask questions, they’re reshaping how we make decisions. And that includes how we shop, who we trust, and where we discover products.

The decline of traditional search

For decades, buying started with a search: “Best noise-cancelling headphones under €200.

”This query would send users down a familiar path: scanning blue links, opening tabs, reading listicles, comparing reviews, checking prices, closing pop-ups, and repeating until either fatigue or decision.

But now?

That same question asked in an LLM-powered chatbot might return a single, confident, conversational answer, including product suggestions with reasons why, not just based on popularity, but on context and intent.

LLMs change the buyer journey

LLMs don’t just return results, they hold conversations. They ask follow-up questions. They clarify. They guide.

In doing so, they’re compressing the buying journey: from awareness to consideration to decisión into a single interaction.

his shift has massive implications:

  • Fewer clicks. More answers.
  • Less reliance on ads. More focus on trust.
  • Fewer brand-driven messages. More AI-curated recommendations.

What this means for brands

If you’re a brand today, being “ranked #1” on Google matters less if the AI answering your customer’s question doesn’t mention you.

Your product might be perfect for someone but if it’s not part of the LLM’s training data, knowledge base, or recognized as trusted… you’re invisible.

Visibility, in the LLM era, is no longer about SEO tricks or high ad spend.

It’s about relevance, reputation, and resonance.
