What Is AI Search and How Is It Different From Google?

Written for somebody who has noticed that searching feels different and wants to know what actually changed. One answer with a few sources instead of ten links, which is better for the person asking and more complicated for the business being asked about.

What the phrase covers

What AI Search Means

AI search covers two things people frequently treat as one. Assistants somebody goes to deliberately and asks a question of. And generated answers appearing above ordinary results when somebody searches the way they always have.

Going somewhere to ask. The deliberate version.

Somebody opens an assistant, types a question in ordinary language and reads a reply. They did not intend to search. They intended to ask, which turns out to change the shape of the question considerably.

Being answered without asking for it. The version most people meet first.

Somebody searches normally and receives a written answer above the familiar links. Nothing about their behaviour changed. What changed is what the page gave back.

Why the distinction matters. The second group is much larger.

Plenty of people who would say they have never used AI search are being given generated answers several times a day. Any assessment of whether this affects your business has to count both.

What this page is for. The phenomenon rather than the response to it.

This page describes what changed from the searcher's side. What a business does about it sits in our pillar guide. We have kept the two apart deliberately rather than writing the same page twice.

This page is reviewed monthly. The landscape in block three moves faster than anything else here.

One answer, a few sources

How It Differs From A Results Page

A results page hands you a list and lets you choose. An answer hands you a conclusion and names where some of it came from. That single change produces most of the consequences in this subject.

The list is gone. Along with the chance to be second.

Ten links meant ten businesses had some visibility, unevenly distributed. A handful of sources means a handful. The rest are not shown at all. Our guide to how these systems assemble an answer covers what that does to the idea of a position.

The comparison happens before you see anything. Somebody else weighed the options.

On a results page a person compares the choices themselves. In an answer the comparison has already been performed and presented as a conclusion. The reader receives a shortlist rather than assembling one.

What that does to the value of appearing. Raises it and narrows it.

Being one of three named businesses in a written recommendation is worth considerably more than being fourth on a list of ten, since the recommendation carries an implied endorsement. Being absent is worth nothing at all, where being tenth was worth a little.

The part that is genuinely better for the person asking. Worth saying.

For a complicated question, having something read several sources and summarise them is a real improvement on opening six tabs. The alarm about this subject frequently forgets that people are using it because it works.

Where People Are Actually Doing This

Four surfaces, checked at the end of July 2026. This block dates faster than anything else on the page, so treat the examples as current at that date rather than as permanent.

Inside a search engine. The largest surface by a wide margin.

Google's AI Overviews place a generated answer above ordinary results. Google also announced a fuller conversational AI Mode inside Search at its developer conference in 2025. Most people meeting AI search are meeting it here without having chosen to.

Standalone assistants. Where somebody goes deliberately to ask.

ChatGPT, Google's Gemini, Anthropic's Claude and Perplexity are the products most people mean when they use the phrase. Perplexity is the one that shows its sources most consistently, which makes it the only place a business can readily watch this happening. Our guide to Perplexity covers why that matters.

Inside a browser. The newest surface and the one to watch.

Browsers with an assistant built into the browsing itself, rather than as a website you visit. As of this check the notable examples are OpenAI's Atlas and Perplexity's Comet. This surface is young enough that anybody describing its long term significance is speculating.

Inside tools people already use for work. The hardest to observe.

Microsoft's Copilot sits inside the software many businesses already run. Nothing about it looks like search from the outside, which is precisely why it is easy to underestimate.

What the four have in common. None of them shows you a list.

Which parts of this block are documented. Worth separating.

The existence of these products is documented by the companies themselves. So is Google's own announcement of AI Mode in 2025. Which surface any particular customer of yours actually uses is our observation of a moving landscape rather than anything published. We keep those two apart throughout this cluster, because most writing on the subject does not.

Behaviour, not adoption figures

How It Is Changing The Way Customers Find Businesses

Three changes in how people behave. We are not going to quote you adoption percentages, because the circulating ones are unsourced or measure different things. The behavioural changes are observable without them.

Questions got longer and more conversational. The clearest change of the three.

People type what they would say to a person rather than the two or three words they learned to type into a search box. Questions arrive with conditions attached: a budget, a location, a constraint, a comparison. That favours material that answers a specific situation over material covering a subject broadly.

More of the comparison happens before any contact. The change with the largest commercial effect.

Somebody choosing between options can now have the comparison performed for them without visiting anybody. By the time a business hears from them, the choosing has largely happened, which means the shortlist was formed somewhere the business could not see.

The shortlist arrives already made. And you are on it or you are not.

An enquiry that once began with somebody browsing several options now frequently begins with somebody who has been told which two or three to consider. Winning that enquiry is easier. Being in the set in the first place is harder to influence and impossible to observe.

What has not changed about the behaviour. The last step.

People still check the business themselves before committing. The recommendation gets verified, which is why block six matters as much as this one.

The commercial consequence, plainly

What It Does To Website Traffic

An answer given in full removes the reason to visit. That is the whole mechanism. It affects different pages so unevenly that a site total tells you almost nothing.

Pages that lose most. Two kinds. They are the same two kinds.

Definitional content. Anything explaining what a thing is, what a term means or how something works in general. These questions are exactly what an assistant answers best. A complete answer leaves nothing to click for.

Quick answer content. What something typically costs, how long something usually takes, whether two things are compatible. Short factual answers, delivered without a visit.

Pages largely unaffected. Also two kinds.

Transactional pages. An answer cannot sell somebody a product, take a booking or complete a purchase. Where the next step requires your website, the visit still has to happen.

Local intent. Somebody who needs a business nearby to attend is not served by prose. Neither is somebody wanting to ring today. Our guide for local businesses deals with which local searches are and are not affected.

Why the distinction matters more than the total. It tells you whether to worry.

A business whose traffic was mostly definitional has a real problem. A business whose traffic was mostly people wanting to book something has a much smaller one. The same overall decline means different things in those two cases, which is why our guide to affected industries sorts by the shape of the decision rather than by sector.

The alarm is frequently overstated

What It Does Not Change

A great deal of what actually drives a business is untouched by any of this. Published material on the subject tends to skip that, since alarm holds attention better.

People still buy from businesses. Not from answers.

An assistant can tell somebody which type of firm they need. It cannot install anything, attend anywhere, dispense advice under a professional obligation or take responsibility for the outcome. The transaction still happens between two parties.

People still check. Recommendations get verified.

Somebody given two names looks them up, reads reviews, glances at the website and forms an impression. That step is unchanged and it is where a great deal of the deciding still occurs. A business named in an answer with a neglected profile and no reviews loses at that point rather than at the earlier one.

People still want to speak to somebody. Especially where it matters.

For anything expensive, difficult or worrying, the reassurance of a conversation is not substitutable. Answering the phone quickly remains one of the strongest competitive advantages a small business has.

Reputation still travels. Locally and by word of mouth.

Being recommended by a neighbour has not stopped mattering. What changed is that the recommendation now gets checked online, which makes being findable more important rather than less.

Why this block exists. Proportion.

A business reading only the alarming version of this subject concludes it has to rebuild everything. The accurate version is narrower. Knowing which parts are untouched is what makes the rest affordable.

Measured, with no prediction

Whether This Replaces Search

Nobody knows. Anybody telling you how this settles is guessing. What can be said is what is observable now, which is less dramatic than either the enthusiasts or the doom merchants suggest.

What is observable. Three things.

Conventional search results still exist and still carry enormous volume. Generated answers now appear above them on a substantial share of informational questions. And assistants have become an ordinary way for many people to ask things, alongside rather than instead of searching.

What that pattern looks like. Addition rather than replacement, so far.

People appear to be using both, choosing by the kind of question. That may continue. It may not. The accurate position is that the shape of this in three years is unknown to us, as it is to everybody selling you a view of it.

Why we refuse to predict. The record is poor.

Confident predictions about search have a long history of being wrong in both directions. We would rather tell you what we can see and revise it than commit to a forecast that would make this page look foolish.

What follows practically. Do not bet the business either way.

Abandoning conventional search visibility on the assumption it is finished would be reckless. Ignoring generated answers entirely would be complacent. Work that helps in both cases is the sensible response to not knowing, which is the argument our strategy guide is built on.

Questions people ask

AI Search

What is AI search?
Two things people treat as one. Assistants somebody goes to deliberately and asks a question of. Generated answers appearing above ordinary results when somebody searches the way they always have. The second group is much larger, since plenty of people who would say they have never used AI search are given generated answers several times a day.
Where is this actually happening?
Four surfaces, checked at the end of July 2026. Inside a search engine, where Google's AI Overviews sit above ordinary results and Google announced a fuller AI Mode at its developer conference in 2025. Standalone assistants, meaning ChatGPT, Gemini, Claude and Perplexity. Inside browsers with an assistant built in, where Atlas and Comet are the notable examples. And inside work software such as Microsoft's Copilot.
Will this reduce our website traffic?
It depends entirely which pages your traffic came from. Definitional content explaining what something is loses most, as does quick answer content covering what something costs or how long it takes, because a complete answer leaves nothing to click for. Transactional pages and local intent are largely unaffected, since an answer cannot take a booking or attend your house. The same overall decline means very different things in those two cases.
How is it changing the way customers find us?
Three ways. Questions became longer and more conversational, arriving with conditions attached, which favours material answering a specific situation. More of the comparison happens before any contact. And the shortlist arrives already formed, so an enquiry now often begins with somebody who has been told which two or three to consider. Winning that enquiry is easier. Being in the set is harder to influence.
What does it not change?
More than the alarming coverage suggests. People still buy from businesses rather than from answers, since nothing generated can install, attend or take responsibility. Recommendations still get checked, so a business named in an answer with a neglected profile loses at that point instead. People still want to speak to somebody about anything expensive or worrying. And local reputation still travels, which makes being findable more important rather than less.
Is this replacing Google?
Nobody knows. Anybody telling you how it settles is guessing. What is observable is that conventional results still carry enormous volume, generated answers now appear above them on many informational questions. Assistants have become an ordinary way to ask things alongside rather than instead of searching. That looks like addition rather than replacement so far. We would rather revise that than predict.
