AI vs. Google Search: When Do Users Choose Which (And What It Means for Your Brand)

Your potential customers are searching for products and services right now — but not necessarily on Google. A growing number of them are opening ChatGPT, Gemini, or another AI chatbot instead. So does that mean SEO is dead and Google no longer matters? Not quite. New research from the Nielsen Norman Group (NN/g) reveals something far more nuanced: users are deliberately switching between AI and traditional search depending on the task at hand. Understanding when and why they make that switch could be one of the most important things your brand does this year.

The Core Finding: AI and Search Are Complementary, Not Competitors

In a recent observational study, NN/g watched real users tackle real tasks — trip planning, product research, health questions, hobby deep-dives — and tracked which tools they reached for at each stage. The headline? Most participants (6 out of 9) moved back and forth between AI chatbots and traditional search within a single research session. They weren’t loyal to one tool. They were strategic.

The pattern that emerged was clear:

AI for exploration, synthesis, and handling complexity
Traditional search for verification, trust, and specific facts

4 Reasons Users Are Choosing AI Over Google

01. AI Is the Perfect Starting Point When You Don’t Know Where to Begin

Traditional search requires you to know what you’re looking for – or at least how to phrase it. AI doesn’t. Users in the study frequently opened chatbots with vague, exploratory prompts when they were still figuring out the shape of their question. One participant who had just bought a Kindle didn’t even know what options existed for free books, so he asked ChatGPT in plain English. The AI gave him a structured list of possibilities, helping him narrow down what he actually wanted.

02. AI Handles Multiple Constraints Better Than Search

Try typing “4-night golf trip for 4 people under $1,000 per person not east of the Mississippi” into a search bar. You’ll get a mess. Type it into ChatGPT and you’ll get a structured list of destinations tailored to exactly those requirements.

One study participant planning a bachelor golf trip did exactly this. His reasoning was straightforward: AI handles multiple constraints far more naturally than Google can. For brands offering products or services with multiple variables – pricing tiers, locations, package options, eligibility criteria – this is a significant signal about how your audience is now researching.

03. AI Saves Clicks and Reduces Research Fatigue

Users repeatedly mentioned that AI saved them from opening 10 browser tabs to gather the same information. AI chatbots aggregate information from multiple sources and surface only what’s relevant to the specific query, dramatically cutting the interaction cost of doing research.

This was especially true for product reviews. Multiple participants preferred asking Gemini or Rufus (Amazon’s AI) to summarise customer sentiment across hundreds of reviews, rather than reading through lengthy, technical individual reviews themselves. As one participant put it, sometimes there’s just too much detail – they wanted the verdict, not the full breakdown.

04. AI Reduces the Mental Load of Comparing Options

When users compare options across different websites, they traditionally have to hold everything in working memory – or scribble notes. AI solves this elegantly. In the study, a participant spent 20 minutes manually noting hiking trails from two different websites before being asked to try Gemini for the same task. Gemini delivered a sorted, summarised list in a fraction of the time.

More AI-savvy users took this even further, explicitly asking for comparison tables with pros and cons – a format that traditional search simply cannot replicate.

4 Reasons Users Still Trust Google Over AI

01. Search Is a Validation Tool

The golf trip planner from the study is a perfect example: he used ChatGPT to discover and shortlist resorts, then immediately Googled each one to find its official website and confirm the details. This ping-pong behaviour was common. Users treat AI as a helpful but fallible assistant. Search is where they go to check its homework.

In one session, ChatGPT listed a New York resort as a Midwest option. The participant caught it immediately, and it visibly dented his trust in the tool. AI mistakes are memorable – which is why verification through search remains a default behaviour.

02. Pricing and Specific Facts Go Through Search

Users were consistently reluctant to trust AI for exact numbers. Whether it was course fees, product prices, or subscription costs, participants said they wouldn’t rely on AI figures without first confirming via search or going directly to the brand’s website. The concern was that AI might be drawing from outdated sources or misrepresenting price ranges.

For brands, this has a direct implication: your pricing page, product pages, and key fact sheets need to be clearly structured, easily discoverable, and regularly updated.

03. High-Stakes Decisions Demand Trusted Sources

The higher the stakes, the more users want authoritative, verifiable sources. A participant researching a car purchase was far more rigorous than someone buying a $20 gadget. A participant looking into omega-3 health information went straight to government health websites and university research, bypassing AI entirely.

This matters enormously for industries like healthcare, finance, legal services, or any significant B2B purchase. Being a credible, citable source is more important than ever.

04. Citations in AI Don’t Fully Resolve Trust Issues

Even when AI tools provided source links, users struggled to understand which specific claims were backed by which source – and which parts were uncited synthesis by the AI. This ambiguity pushed users toward traditional search where they could go directly to the original source and read it themselves.

What This Means for Your Digital Marketing Strategy

This research isn’t just academically interesting – it has direct implications for how you structure your digital presence. Here’s what brands should take away:

So what does this mean for your digital presence?

Your website is still the destination: Users may discover you through AI, but they come to your website to verify. Make sure your site is fast, credible, and clearly structured.
Structured, factual content wins in both worlds: AI tools surface well-organised, accurate content. So does Google. Invest in clear, thorough, regularly updated pages.
Pricing and key specs must be accurate and up to date: Users won’t trust AI on this – they’ll come to you directly. Make it easy to find.
Build authority for high-stakes queries: If your audience makes significant decisions in your category, being a citable, trusted source matters more than ever. Invest in thought leadership, case studies, and expert content.
Optimise for AI discoverability, not just SEO: As users increasingly start their research journey in AI chatbots, your brand needs to be part of those conversations – which means creating content that AI tools can accurately reference and cite.

The Bottom Line

The question isn’t whether your customers are using AI or Google. They’re using both, often within the same research session. The smarter question is: does your brand show up confidently in either channel? And when users arrive at your website to verify what AI told them, does your content earn their trust?

At Nimax Digital, we help brands build a digital presence that works across both worlds, from SEO-optimised content that ranks on search, to authoritative, structured content that AI tools are more likely to surface and cite. If you’re not sure how your brand is performing in either, let’s talk.
