Research led by One Day: AI vs Search Engines Usage.

Is AI really killing Traditional Search Engines? We surveyed 1,000 UK users to find out.

The results show we aren't abandoning search engines; we’re using them to fact-check AI. We call this the Verification Loop. While AI is great for quick summaries, we still turn to Search Engines for the final proof. For brands, this means the path to a sale is now a hybrid journey: AI provides the draft, but Search Engines like Google, Bing, etc. provide the facts.

We conducted this research to provide brands with a clear, data-backed roadmap. Instead of guessing where the audience is, this data proves that the search journey has evolved into a "Verification Loop." Understanding why users start in one place and finish in another is essential for any advertiser looking to remain relevant as these two technologies learn to coexist.

Read below for our analysis of the key findings and the strategic shifts you should adopt.

70% Daily Habit: Traditional Search is Still the Front Door

Traditional search remains the primary gateway to the internet. 63% of users start their discovery on a search engine, while only 6% start with an AI tool. Frequency data confirms this: 70% of people use search engines multiple times a day, whereas 32% have never used AI for information. Search engines are a universal habit; AI is still a secondary addition.

51% Use Search Engines to verify Facts

Users pick their tool based on the task. 51% use traditional search for facts and 43% for finding specific websites or logins. In contrast, AI has carved out a niche for "cognitive" work: 29% use it to explain complex topics and 27% for detailed, multi-part questions. Essentially, search engines are for "where" to go, while AI is for "how" to understand a topic.

45% Choose Authority: The Massive Trust Gap

Trust is AI’s biggest hurdle. 45% of users trust search engines for factual accuracy, while only 4% trust AI more. This lack of confidence has created a "Verification Loop", where 65% is the combined total of users who reported that they verify information after using an AI tool, and feel they must double-check AI-generated information elsewhere. 59% of users report no change in their search habits, and 11% actually use search engines more now to verify AI claims.

24% Prioritise Speed: Convenience vs Credibility

The drivers for each tool are distinct. 24% choose AI because it is better at summarising complex topics, valuing speed over a list of links. However, 25% stick to search engines because they are more trustworthy for news, and another 25% find it easier to verify sources there. AI wins on efficiency, but search engines win on reliability.

What does this mean for brands?

The Search Split: Learn on AI, Find on Google

This research across 10 key metrics highlights a clear divide in user behaviour: AI is for exploration, but search engines are for execution. Throughout the study, we see that users treat AI as a research assistant to simplify topics and gather ideas during the initial "learning phase." However, when it’s time to take action, like visiting a specific brand, making a purchase, or confirming a fact, they return to traditional search engines to finalise the journey. This split creates a two-step process where brands must first be the helpful answer in an AI conversation and then the trusted, clickable authority in the search results.

Read below for our required approach on how to navigate AI and Search Engines usages amongst your audience.

The "Double-Check" Search

Users often take a brand name they found via AI and search for it on Google to see if it’s real. When AI suggests a restaurant, the user will probably go search “X restaurant reviews'“ on google, or even just check how many stars it has on Google Maps.

Required approach: Be ready for the follow-up. Ensure your official site, Google Business Profile, and reviews are perfect. If AI recommends you, you must own the "verification search" that follows.

Move Beyond "Top 10" Lists

With 29% of users using AI to decode complex topics, surface-level content is losing value. People are becoming lazy, they want straight to the point information, and not have to read through 50 pages of a research piece to understand a topic.

Required approach: Create "Expert Explainers." Produce deep, structured guides that solve specific problems. This makes it easier for AI models to cite your brand as the primary authority during a user's research.

Don't underestimate Search Engines (yet)

70% of people still use traditional search engines every day. Shifting your entire budget to AI optimization is a mistake. You base your strategy on how people behave, what they use and what they like.

Required approach: Use a hybrid approach. Keep using search ads and SEO to drive immediate sales and traffic, while using AI-friendly content to capture users in the early discovery stages.

Proof is Your Best Marketing

Since 32% of users don’t fully trust either tool, transparency is a competitive advantage. Be straightforward in your approach, if you did use AI, being honest about how you used it will win you your audience’s trust.

Required approach: Show your receipts. Clearly link to sources, case studies, and data on your website. In a world of AI "hallucinations," the brand that provides the most visible proof wins the customer.

AI for Research, Search Engines for Action

This research proves that AI is not replacing traditional search. Instead, it has become a tool for the initial research phase. Users value AI for summarising complex topics, but they still rely on search engines for transactions and factual accuracy. With 65% of users double-checking AI results, the search journey has become a loop where AI provides the first draft and Search Engines provide the final proof. To succeed, brands must be the expert answer in AI and the trusted authority in search results.

Frequently Asked Questions.

We partnered with independent panels to survey 1,000 UK internet users to ensure the findings reflect broad, real-world search behaviour. The study utilised a structured questionnaire designed to compare daily habits across both legacy search engines and emerging AI platforms. This scale allows us to provide statistically significant insights into how the average person navigates the internet today.
Yes. One Day Agency commissioned this study to provide an objective look at the search landscape, focusing on user behaviour over platform marketing. We have no affiliation with specific search engines or AI developers, ensuring the data remains unbiased and transparent. Our goal is to provide brands with a raw, unfiltered view of how consumers actually find and process information in 2026.
A representative sample of the UK public, spanning ages 18 to 55+, to capture how AI adoption is scaling across different life stages. The cohort includes a significant percentage of older professionals and retirees, moving the data beyond the "early adopter" tech bubble. This ensures the results reflect the habits of the general population rather than just a niche group of young enthusiasts.
Our data showed that "verification" is the most significant new behaviour in the search journey. Understanding this loop allows brands to capture users at the exact moment they decide to trust a product. Since trust in AI-generated facts remains low, users now treat Google as a "second opinion" to confirm what they have learned. Mapping this behaviour helps advertisers identify the precise touchpoints where a consumer moves from curiosity to conversion.
Continue to invest in traditional SEO for high-intent and transactional keywords, but begin adapting your content architecture to be easily summarised by AI models for top-of-funnel research. Brands should focus on becoming the "expert source" that feeds AI summaries while maintaining a strong, authoritative presence in search results. By doing so, you ensure you are present when a user is exploring an idea and dominant when they are ready to act.
