AI Search is Here — What It Means When Buyers Ask ChatGPT Instead of Google
A growing share of Australians now ask ChatGPT, Perplexity or Google's AI Overviews for service business recommendations instead of running a regular Google search. The businesses that get named are the ones with structured authority signals — not the ones with the cheapest ads.
Something has shifted in the last twelve months that most service businesses haven't fully noticed yet.
The customer who would have searched "plumber Norwood" on Google two years ago is increasingly asking ChatGPT "who's a good plumber in Norwood" — or Perplexity, or Google's own AI Overviews, or Apple Intelligence on their phone, or one of half a dozen other AI assistants that didn't exist in 2023.
This isn't a small shift. ChatGPT alone serves more than 800 million weekly users globally. In Australia, generative AI search query volume has roughly tripled year-on-year for the last two years. AI Overviews now appear on around 18% of Google search results in Australia and rising. The audience isn't moving overnight, but the curve is steep enough that you can't ignore it.
The problem is: the rules of getting found change completely when the surface stops being a list of ten ranked links and starts being a single synthesised answer.
This post is about what's actually different, and what a service business needs to do about it.
The shift from ranking to being named
In traditional Google search, "winning" means appearing on page one — ideally in the top three results or the Map Pack. Ten businesses get a fair shake at each search. The user picks one based on the snippet, reviews, ad copy, whatever.
In AI search, "winning" means being one of the one or two businesses the model names in its answer.
Ask ChatGPT "who's a good plumber in Norwood Adelaide" and the answer doesn't return ten plumbers ranked one through ten. It returns a synthesised paragraph that says something like:
"For Norwood, Smith Plumbing is well-regarded for emergency plumbing — strong reviews on Google and a focus on same-day service. For larger jobs, Adelaide Hot Water Specialists are often recommended for their hot water system expertise."
That's it. Two plumbers named. Everyone else — including some of the highest-ranked Google results — simply isn't mentioned.
This compresses the available "real estate" from 10 results to 2. The competitive stakes per query just went up by 5x.
What determines who gets named
AI search doesn't rank by traditional SEO signals alone. It synthesises an answer by pulling structured information from multiple sources — websites, reviews, directories, Google Business Profile data, knowledge graphs, news, social. The businesses that get named are the ones with the strongest structured authority signals across that wider data set.
In practice, that means six things matter more than they used to:
1. Clear, unambiguous business identity across sources
If your business is "Smith Plumbing Pty Ltd" on your website, "Smith's Plumbing" on Google, "Smith Plumbing Adelaide" on Yellow Pages and "Plumbing By Smith" on True Local, AI models can't confidently merge those into one entity. You appear as four half-mentions instead of one clear authority.
The fix is the same as it's been for years — NAP consistency (Name, Address, Phone identical across every listing) — but it matters more now than ever.
2. FAQ schema and structured Q&A
AI models extract answers from structured Q&A markup. If your website has FAQ schema with the questions a customer might ask ("How much does drain clearing cost?", "Do you offer emergency plumbing in Norwood?", "What plumbing services do you offer in Adelaide?"), the AI can pull your answer directly into its response.
Without FAQ schema, the AI has to infer answers from your prose. Your prose probably wasn't written for AI extraction. You lose.
3. Reviews as truth signals
AI models weight reviews heavily as a credibility signal. Not just count, but quality, recency and source diversity. A business with 100 Google reviews, 30 RateMyAgent reviews and 15 industry-specific directory reviews carries more authority than a business with 200 Google reviews and nothing else.
Spread your review collection across platforms intentionally — Google, your industry's directories, your sector's review sites — not just Google alone.
4. Topical depth on your own site
Old SEO rewarded keyword density. AI search rewards topical authority — having genuinely comprehensive content on a subject. A plumber's website with 30 pages covering every plumbing topic (emergency response, hot water systems, gas fitting, drain clearing, bathroom renovation, commercial plumbing, suburb-specific pages, FAQs, troubleshooting guides) reads as an authority. A 5-page brochure site doesn't.
When AI synthesises an answer about plumbing in your suburb, it pulls from the most topically authoritative source it can find. That should be you.
5. Citation diversity
AI models cross-reference sources. A business mentioned consistently across your Google Business Profile, your website, three Australian directories, two industry sites, a Wikipedia or local-news mention, and a relevant community blog reads as multiply-verified. A business that only exists on its own website and Google reads as un-corroborated.
Build citations deliberately — directories, industry sites, local-area mentions, partnerships with other local businesses that link back.
6. Recency
AI models prefer recent content. A blog post from 2026 outranks an unmaintained one from 2022. A GBP with weekly posts outranks a dormant one. A review velocity of 2–3 reviews per month outranks 50 reviews collected in 2023 and silence since.
Stay active. The cost of staying active is small. The cost of going dormant is invisibility.
The compounding cost of being absent
Here's the part that makes AI search urgent rather than just interesting.
In traditional search, the business that wasn't on page one still got some traffic. People scrolled. People clicked "more results". People searched alternative terms. Visibility was a gradient.
In AI search, the business that doesn't get named gets zero of that query's traffic. There's no "page 2 of ChatGPT." Either the model says your name or you might as well not exist for that buyer's decision.
If 20% of relevant local searches now happen via AI surfaces (a conservative 2026 estimate, rising fast), and your business isn't being named in those AI answers, you're losing one in five of your potential customers before they ever see your website.
In 2027, that share is likely 30–40%. In 2028, possibly 50%.
The cost of waiting to optimise for AI search is being invisible to half your future customer base.
What to actually do in 2026
The good news: a lot of what makes AI search work is the same fundamentals as traditional SEO, just emphasised differently.
If you're starting from a normal SEO position, the highest-leverage moves are:
- Add FAQ schema to every service page. Most service business websites have FAQs as plain text. Marking them up with schema is a 30-minute developer task that moves them from invisible-to-AI to extractable-by-AI.
- Build out structured content depth on your top 2–3 priority topics. If you're a roofer, you don't need 50 thin pages — you need 5–10 genuinely comprehensive ones covering metal vs tile, repair vs replacement, insurance claims, suburb-specific roofing markets.
- Audit and consolidate your NAP across every directory and listing. Use a free tool like Yext or BrightLocal's free audit to find inconsistencies. Fix them.
- Collect reviews on at least 3 platforms. Don't put all your eggs in Google's basket. Industry-specific platforms and second-tier directories carry weight.
- Publish recent content — at any cadence you can sustain. One blog post a month with proper FAQ schema beats 12 posts in December and silence the rest of the year.
- Test your AI visibility. Open ChatGPT, Perplexity and Google AI Overviews. Search for the queries your customers would use. Is your business named? If not, you have a roadmap.
