Updated June 2026. ChatGPT passed 900 million weekly users and Australian B2B buyers are now shortlisting vendors in AI tools before they ever open Google. This post explains how AI search works, why it differs from Google, what builds visibility inside it, and why the brands acting now are compounding an advantage that will be significantly harder to close in 12 months.

The three ways AI search differs from Google
What does “being visible in ChatGPT” actually require?
A procurement manager needs a new digital marketing agency. She doesn’t open Google. She opens ChatGPT and types: “best digital marketing agencies in Melbourne for B2B companies.”
Ten seconds later, she has three names with reasons. One of them is your competitor, and you’re not mentioned. She doesn’t run a second search; she clicks the first name.
This is already happening across every category in Australia. The question is whether you’re in those answers.
How has buyer research actually changed?
AI tools like ChatGPT, Gemini, and Perplexity now give buyers a direct recommendation instead of ten links to evaluate. Australian B2B buyers increasingly use these tools for initial vendor research before they ever open Google, which means brands are being shortlisted or eliminated at a stage most marketing strategies don’t track.
The old research journey: Google search, scroll through results, click several links, form a view over multiple sessions. The new one: open ChatGPT, ask a specific question, get a named recommendation, click through. A step that once gave every brand a fighting chance has been compressed into a single AI-generated answer.
The scale of what’s already moved makes this impossible to treat as an emerging trend. ChatGPT passed 900 million weekly users in February 2026 (source: OpenAI), and Gartner has projected a 25% decline in traditional search engine traffic by 2026 as AI search captures that research volume. This is not a fringe use case for a small subset of tech-savvy buyers. It is mainstream buyer behaviour, accelerating across every category.

“Your competitor being recommended in ChatGPT isn’t luck; it’s the result of a strategy.”
The brands that show up in AI-generated answers today built that presence deliberately. It doesn’t happen by default.
How does ChatGPT decide what to recommend?
ChatGPT synthesises recommendations from its training data and, for ChatGPT Search, live web results pulled through Bing. Brands with a clear online presence, consistent third-party mentions, and structured, answerable content are significantly more likely to appear.
Four things shape whether your brand gets named:
Coverage in authoritative sources, industry publications, and review platforms like Clutch or G2 feeds ChatGPT’s training data. Coverage on low-authority sites contributes very little.
ChatGPT needs to understand confidently what your business is, who it serves, and where it operates. Inconsistent descriptions across your website, LinkedIn, and directories create ambiguity that reduces citation confidence.
Pages with clear headings, short direct answers, and FAQ-style structure are far more citable than dense narrative copy. AI models extract answers, not paragraphs.
Wikipedia pages, Clutch reviews, press coverage, and analyst mentions are independent authority signals. ChatGPT weights them heavily because they’re corroboration it didn’t produce. A Clutch review that says “they grew our organic traffic by 340% over 14 months” is the kind of specific, verifiable claim AI systems extract as evidence of real capability.
The practical upshot: a brand with excellent website content but almost no third-party presence is less visible to AI than a brand with average site content and strong independent coverage. Most brands have the former problem without realising it.
The three ways AI search differs from Google
AI search doesn’t return ten results and let buyers choose. It names two to four brands and moves on. The tactics that built your Google visibility won’t carry over automatically, and the competitive dynamics are structurally different.
On Google, ten brands can each hold a meaningful position on page one. In a ChatGPT recommendation, there are typically two to four slots. The difference between being named and not named is categorical, not a matter of degree.
There are also no ads. Every Google result sits adjacent to paid listings that can be bought. AI-generated recommendations currently have no equivalent, which means early movers are occupying prime real estate through earned authority alone.
The third difference is the zero-click dynamic. When a buyer gets a named shortlist from ChatGPT, the brands not on that list may never get a website visit from that buyer. There’s no “page two” equivalent. Brands eliminated at the AI stage don’t get a second chance in that research session.
ChatGPT, Perplexity, and Gemini operate differently
The three dominant AI research tools each have a distinct citation logic, which matters for how you approach visibility:
| Platform | How it works | What it rewards |
|---|---|---|
| ChatGPT | Training data plus Bing’s live index for ChatGPT Search queries. | Bing indexing, structured content, consistent brand entity signals. Many brands underinvest in Bing because they focus entirely on Google, which creates a direct gap in their ChatGPT visibility. |
| Perplexity | Works as a live research assistant, citing every source it uses with explicit URLs. | Strong, current third-party coverage. Clutch profiles, press mentions, and review platforms all feed its live citations directly. |
| Gemini | Closely integrated with Google’s own index and AI Overviews. | Favours content that already ranks well on Google: structured data, strong E-E-A-T signals, pages Google has already validated. |
Each platform rewards a slightly different combination of signals. A strategy that only optimises for one platform will leave the others unaddressed. For a deeper breakdown of how GEO and AEO work across each platform, see our post on GEO vs AEO vs SEO for Australian businesses.
What does “being visible in ChatGPT” actually require?
Building visibility across AI platforms, a practice called Generative Engine Optimisation (GEO) or Answer Engine Optimisation (AEO), comes down to four things: clear brand entity signals, consistent third-party mentions, structured and answerable content, and citations in authoritative sources.
None of this is entirely new. What’s changed is that these things now need to work together specifically for AI visibility, not just for Google rankings. The same structural work that helps a page rank on Google also makes it more citable by ChatGPT, but the two disciplines have meaningfully different priorities, especially around third-party presence and entity consistency.
Brand entity signals mean your business is described consistently everywhere: your website, LinkedIn, Google Business Profile, Clutch or G2. Schema markup on your site (Organisation schema with your name, description, founding date, service areas, and links to third-party profiles) is the machine-readable version of that declaration.
Third-party coverage is where most brands have the largest gap. Wikipedia, verified Clutch profiles with specific client outcomes, and genuine press mentions all function as independent authority signals. AI systems weight these heavily precisely because they’re corroboration the AI didn’t produce itself.
Structured, answerable content means leading each section with a direct answer in the first 60 words, not burying the point in narrative. FAQ sections, comparison tables, and clearly labelled headings all improve AI extractability. For more on what this looks like in practice, see our guide on what Answer Engine Optimisation involves.
SHOUT DIGITAL IN AI SEARCH
Shout Digital has been named by Perplexity as the best Melbourne GEO agency for e-commerce brands needing premium, competitive-category performance. That’s what strong AI visibility looks like: a third-party platform, unprompted, naming a specific brand as the leading option for a specific category and geography. Shout Digital tracks brand mention rate and citation share across ChatGPT, Gemini, and Perplexity as a standard deliverable for clients. Most agencies in Australia don’t do this at all.
For brands wanting to understand Shout’s full approach to AI search visibility, Shout Digital’s GEO and AEO services cover the methodology in detail.
Is it too early to act?
Brands building AI visibility now are compounding an advantage that will be significantly harder to close in 12 months. AI platforms develop preferences for sources they encounter repeatedly, and the brands appearing consistently today are reinforcing their own inclusion through repetition.
Wikipedia coverage, Clutch review depth, and consistent press citation each take months to establish. There is no shortcut. A brand starting this work in mid-2027 is building against incumbents who have been accumulating those signals for over a year, and AI systems will have been trained or fine-tuned on that existing citation history.
The brands that will dominate AI-generated shortlists in 2027 are largely building those signals right now. The window to get ahead of the default isn’t closing, but it is narrowing.
WHAT TAKES MONTHS TO BUILD
- A verified Clutch profile with specific client outcome data
- Press citations in industry publications that AI systems treat as authority signals
- Wikipedia presence or consistent third-party editorial mentions
- Bing indexing depth that feeds ChatGPT Search results
Shout Digital’s GEO and AEO services are built specifically for growth-stage and established Australian brands that want to be on every buyer’s AI shortlist before their competitors establish the position. The first question to answer is why your competitors are already there.
