How AI Search is Different From Voice Search for Local Businesses

Right. So I've had about fifteen conversations in the last month where someone's said to me "but Dan, we already did voice search optimisation back in 2019, isn't this AI search thing basically the same?"

No. God no. And I get why it feels that way, because both involve someone asking a question out loud and getting an answer back. But that's like saying a bicycle and a motorbike are the same because they both have two wheels.

Let me show you what's actually different, because if you're running a local business around Hitchin or Stevenage and you're thinking your old voice search stuff has you covered... it really doesn't.

The fundamental difference nobody's talking about

Voice search was about matching keywords in questions. You'd ask your phone "plumber near me" and Google would find pages with those words on them. Maybe add some location stuff. Done.

AI search is reading everything on your site, everything people say about you, everything in your Google Business Profile, then actually understanding what you do and deciding whether you're the right answer. It's not matching words. It's making a judgement call about whether you can solve someone's problem.

I had a client in Letchworth, drainage company. Their voice search optimisation was basically "emergency drain unblocking Letchworth" repeated on every page. Worked fine in 2020. Absolutely tanked when ChatGPT started answering plumbing questions in early 2024. Because the AI would read that page and go "yeah this is keyword spam, they haven't actually explained anything about drains."

We rewrote it. Explained how drains block, what happens if you ignore it, why some blockages need jetting and some need excavation. Suddenly they're getting cited in AI answers. Not because we optimised for keywords. Because we gave the AI enough context to understand they actually know their stuff.

Voice search wanted you to answer one question

Remember all that FAQ schema markup? "What are your opening hours?" "Do you offer emergency callouts?" Short, direct answers to specific questions.

That still matters a bit. But AI search wants to understand your whole business. Not just answer one question.

When someone asks Perplexity or ChatGPT "I need a builder for an extension in Baldock, who's good?" the AI isn't looking for a page that says "extension builder Baldock" seventeen times. It's looking at: - Do you actually do extensions or just repairs? - What size projects do you take on? - How do you price things? - What happens after someone contacts you? - Do you sound like you know what you're doing? - Can you handle planning permission stuff or just the build?

It's reading your entire site and forming an opinion. Then it might look at reviews. Check your Google Business Profile. See if you've written anything useful anywhere else.

Voice search was transactional. AI search is... evaluative? That's not quite the right word but you get what I mean.

The context problem

Voice search was mostly mobile. Someone in their car or walking around going "coffee shop near me." Location was basically the whole game.

AI search happens everywhere. Someone's at their desk at home in Royston, planning a kitchen renovation, asking ChatGPT to help them think through the whole project. The AI might recommend three local kitchen fitters, but it's basing that on way more than proximity.

I'm looking at our analytics for a kitchen company we work with. About 60% of their AI search visibility is coming from long conversations where someone's asking about costs, then timelines, then whether they need planning permission, then what questions to ask fitters. The AI's pulling them into the conversation at multiple points. Not just "kitchen fitter near me."

That never happened with voice search. You got one shot at one question.

Personality actually matters now

This is the bit that sounds soft but it's not. Voice search didn't care if your content was boring. If you had the right keywords and schema, you'd show up.

AI search... look, the AI is trying to recommend businesses it thinks will be good to work with. It's reading your tone. If your website reads like it was written by someone who hates their job and can't be bothered to explain anything properly, that comes across.

I'm not saying you need to be funny or whatever. But you need to sound like a real person who gives a toss. The AI can tell the difference between "we provide high-quality roofing solutions" and "we fix roofs, here's how we do it, here's what goes wrong with most roofs around here."

One of those sounds like a business. One sounds like corporate nothing.

We redid the website for an electrician in Stevenage last year. Took out all the "certified electrical contractor providing comprehensive solutions" stuff. Rewrote it as him just explaining what he does and how he works. His AI search visibility went up 340% in about ten weeks. Not because we did anything clever with schema. Because the AI could finally work out what kind of electrician he was.

Schema is less important, context is more important

Right, this annoys people because everyone spent ages learning schema markup for voice search. FAQPage schema, LocalBusiness schema, all that.

Still useful. Do it. But it's not the magic bullet it used to be.

The AI doesn't need you to mark up your opening hours in a special format. It can just... read your opening hours. Wherever they are on the page. It understands context.

What it can't do is understand your business if you haven't properly explained it anywhere. That's the gap I keep seeing. Local businesses have all the technical stuff sorted, schema's perfect, site speed is good. But nobody's actually written down how they work or what makes them different or why someone should use them instead of the other ten businesses that do the same thing.

The AI needs that context to make a recommendation. Voice search didn't care about any of it.

You need to answer questions that haven't been asked yet

This is the weird one. With voice search, you knew what questions people were asking. Google Search Console told you. "How much does X cost" or "emergency Y in Z location."

With AI search, people are having conversations. They're asking follow-up questions. They're going down rabbit holes. The AI needs to know enough about your business to pull you into conversations that might go in five different directions.

So you can't just optimise for the obvious questions anymore. You need to explain the whole thing. The process. The problems that come up. What you do differently. Why things cost what they cost. What happens if someone needs something slightly unusual.

I know that sounds like a lot of content. It is. But that's what AEO is actually about. Making sure the AI has enough information to understand your business well enough to recommend you in all sorts of different contexts.

Local is still crucial but it works differently

Voice search used location as a filter. "Near me" or "in Hitchin" and you'd get businesses in that area.

AI search understands location but it also understands whether you're genuinely local or just pretending. It'll pick up on the fact you mention local landmarks, or you talk about problems specific to the area, or your reviews are from people in nearby towns.

We work with a bunch of businesses in North Hertfordshire and the ones who get the most AI visibility are the ones who actually sound local. Not the ones who've just shoved town names into their page titles.

There's a drainage company who wrote a page about clay soil in Hertfordshire and why it causes specific drainage problems. Gets cited constantly by AI search. Not because it says "drainage Hertfordshire" but because it's genuinely useful local information that the AI trusts.

So what does this mean for you

If you sorted out voice search a few years back and you're thinking you're covered... you're probably not. The rules changed. It's not about keywords anymore, it's about actually explaining your business properly so an AI can understand it well enough to recommend you.

That's basically what we do all day. Taking local businesses who are good at what they do, making sure the AI actually understands that, so they show up in AI-generated answers. It's not complicated but it is different from the old voice search playbook.

If you're around North Hertfordshire and you want someone to look at where you're actually showing up in AI search versus where you could be, book a call and we'll go through it. Or if you just want to understand how this affects your specific type of business, same thing. I'm not going to try and sell you something you don't need, I just think most local businesses have no idea this shift has happened.
