How AI Search Actually Works — and What B2B Buyers Are Really Doing Online
Understanding the new buyer journey before your competitors do

Your Buyer Has Already Made Up Their Mind. They Just Haven't Called You Yet.
There is a statistic that has been circulating in marketing circles for years, but it has never been more true than it is today: the first 80% of the B2B buying journey happens before a prospect ever speaks to a salesperson.
Buyers research independently. They read, compare, validate, and form preferences — often across weeks or months — before they take any action that makes them visible to your business. By the time they fill in a contact form or book a call, they frequently know which provider they prefer. The conversation with your sales team is often a confirmation exercise, not a discovery process.
This was already the reality of B2B buying behaviour in the era of Google search. Generative AI has intensified it considerably.
KEY INSIGHT
Today's B2B buyer does not just Google options and click through to websites. They ask AI assistants for recommendations, request comparative analyses, and use AI tools to synthesise research that previously took days of independent reading. The buying journey has become faster, more opaque to vendors, and more dependent on AI-generated curation.
What B2B Buyers Are Actually Doing in AI Search
To understand GEO and AEO, it helps to see AI search not as a technology category but as a buyer behaviour. What are buyers actually doing when they turn to an AI assistant in a professional context?
Asking for Recommendations
A procurement manager evaluating marketing technology does not necessarily want to browse twenty options. They ask ChatGPT: 'What are the most effective tools for B2B demand generation in 2025?' The AI synthesises an answer, names specific platforms, and explains why each is relevant. Brands that appear in that answer have effectively bypassed the entire top-of-funnel awareness stage.
Validating Shortlisted Providers
Once a buyer has a shortlist, they use AI to investigate each option. They ask questions like: 'What do people say about [Agency Name]?' or 'What are the strengths and weaknesses of [Service]?' The AI draws on publicly available content — articles, reviews, case studies, thought leadership — to construct an assessment. If your content is thin, vague, or structured poorly, the AI's assessment of your brand will reflect that.
Synthesising Market Trends
Senior decision-makers use AI to stay ahead of developments in their industries. When an AI summarises 'the most important shifts in B2B marketing for 2025,' it is drawing on the content landscape to determine which voices, brands, and perspectives are authoritative. If your brand is contributing original thinking to the market — and doing so in a format AI can extract and cite — it gets included. If your brand is quiet or generic, it does not.
Preparing for Internal Conversations
B2B purchases typically require internal consensus. A champion within an organisation often uses AI to help build the business case for a decision. They ask the AI to help them explain a concept, justify a budget, or articulate the risk of inaction. If your content has shaped how the AI understands the problem space, your framing becomes their framing — before they have ever visited your website.
How AI Search Engines Actually Select Their Sources
Understanding why AI engines prefer certain content over others is the foundation of effective GEO. The selection process is not random, and it is not purely based on traditional SEO signals such as keyword density or backlink count. AI engines weigh several distinct factors.
Authority and Trust Signals
AI systems are trained to recognise authority. They favour content from sources that are well-cited, well-linked, and consistently associated with a particular area of expertise. This is not unlike how a human researcher develops trust in a publication: over time, through repeated exposure to reliable, accurate, and well-referenced material.
For B2B brands, this means that authority is built cumulatively. A single well-written article does not establish an AI-cited brand. A body of work that consistently addresses the same domain with specificity, accuracy, and evidence does.
Structural Clarity
AI engines extract meaning from content by parsing its structure. Pages with clear heading hierarchies, concise paragraphs, and explicit question-and-answer formatting are significantly easier for AI to process accurately. Research analysing 1,000 frequently AI-cited pages found that short paragraphs (averaging three sentences), heavy use of lists, and explicit question-answer formats were near-universal characteristics.
Think of it this way. If you gave a research assistant a book with no headings, no chapter titles, and no index, they could still extract information — but it would take longer and the risk of misrepresentation would be higher. An AI faces the same challenge. Structured content is not just user-friendly; it is machine-friendly.
Entity Recognition
AI models categorise content by entities — specific, identifiable concepts, brands, people, or organisations. When an AI consistently encounters your brand name in association with a particular domain of expertise, it begins to recognise your brand as an entity in that space. This recognition influences citation.
In October 2025, ChatGPT introduced a significant entity update that changed how its model recognises and recommends brands. Businesses that had established consistent entity signals — through structured content, directory listings, social profiles, and third-party mentions — benefited disproportionately from this change. Those without established entity recognition saw no improvement.
KEY INSIGHT
Your brand is either becoming an entity that AI systems recognise and recommend, or it is becoming background noise. There is no neutral ground. Every week of inaction is a week your competitors' entity signals compound while yours remain static.
Specificity and Citable Data
AI engines strongly prefer content that contains specific, attributable claims. A paragraph stating that 'AI search is growing rapidly' carries little weight. A paragraph stating that 'Perplexity AI processed 780 million queries in May 2025, an increase of 239% from August 2024' is both credible and citable.
This has a direct implication for B2B content strategy. The habit of keeping your insights vague to avoid committing to specifics — common in regulated industries and risk-averse marketing cultures — actively undermines your AI visibility. Specific claims, backed by data, are exactly what AI engines are designed to find and cite.
The B2B Buyer Journey Has Three New Stages
The traditional funnel model (Awareness → Consideration → Decision) still holds, but each stage now has an AI layer that sits above it.
Pre-Awareness: AI Defines the Category
Before a buyer even knows they have a problem worth solving, they may encounter AI-generated content that frames the challenge in a particular way. If your brand's language and frameworks have been absorbed into how AI describes your category, you have effectively shaped the buyer's mental model before they began their journey. This is the most powerful and least understood stage of AI-influenced purchasing.
Consideration: AI Curates the Shortlist
When a buyer actively begins researching solutions, they increasingly use AI to generate a shortlist rather than conducting their own broad web research. Being included on that AI-generated shortlist is equivalent to being included in an analyst report a decade ago — it provides a level of implicit credibility that is extremely difficult to achieve through direct marketing.
Decision: AI Validates the Choice
At the point of decision, buyers use AI to pressure-test their preference. They ask the AI to identify potential risks, to surface counterarguments, and to confirm that their chosen provider is indeed well-regarded in the market. Brands with rich, specific, third-party-validated content perform well at this stage. Brands with thin or generic content often fail the final test.
What This Means for Your Marketing Strategy
The implication of all this is not that traditional marketing is dead. SEO, paid media, thought leadership, and relationship-based selling all remain valuable. But they now operate within a broader context in which AI platforms are increasingly acting as gatekeepers, curators, and recommenders.
A B2B brand that ignores this context is essentially choosing to be invisible at the stage of the buying journey where preferences are formed. That is not a sustainable competitive position.
QUICK WINS: WHAT YOU CAN DO THIS WEEK
- Ask three different AI platforms (ChatGPT, Gemini, Perplexity) the top five questions your buyers ask during the sales process. Note which brands appear and whether yours is among them.
- Review your five highest-traffic pages. Check whether each one answers a specific buyer question directly within the first 100 words.
- Identify the three most common objections your sales team hears. Ensure your website has dedicated, AI-extractable content addressing each one.
- Add specific, sourced statistics to your three most important thought leadership pieces. Replace vague claims with precise, attributable data points.
- Ensure your brand is listed consistently across Google Business Profile, LinkedIn, Clutch, and relevant industry directories to strengthen entity recognition.
