How Google Turned Search Intent Into an Advertising Empire

Most advertising has to interrupt something.

A television advert interrupts a programme. A radio advert interrupts a song. A display advert interrupts an article. A leaflet arrives through a door with no reliable knowledge of whether the person behind it is interested in the product, currently shopping for it or mainly wondering why the recycling bin is full again.

Google found a different moment.

When somebody types a query into a search box, they volunteer a small piece of intent. Sometimes it is vague: why is my dog scratching? Sometimes it is comparative: best raw dog food UK. Sometimes it is only a step away from a transaction: buy raw dog food delivery.

That difference became one of the most valuable commercial opportunities in history. In 2025, Alphabet reported $224.5 billion in revenue from Google Search and other activities. That is about $615 million a day.

The number is extraordinary. The underlying idea is almost disarmingly simple.

For marketers, however, the lesson is not merely that Google Ads works. It is that paid search is unusually good at capturing demand—and therefore unusually easy to credit with demand it did not create.

Before Search Felt Measurable

My first substantial professional experience of Google Ads came while I was working for the YMCA at Fairthorne Manor.

Google Ads represented a very small part of the budget. Much more of our marketing activity involved leaflets going into schools. Those leaflets were tangible, familiar and capable of reaching a great many families. They were also not particularly good at telling us which child had taken one home, which parent had read it or whether the leaflet had enjoyed a brief but meaningful career at the bottom of a school bag.

Paid search looked more measurable by comparison, but attribution was still limited. The account felt basic, the data felt incomplete and decisions sometimes felt closer to a stab in the dark than a controlled experiment. SEO was a different discipline then too, both technically and in the way businesses understood it.

I used Google Ads much more while working at RTWiggins. By the time I was working with larger direct-to-consumer brands—and particularly at Paleo Ridge—it had become commercially critical.

That progression mirrors a wider change in marketing. Search moved from being one interesting digital line on a plan to becoming part of the infrastructure through which demand is found, measured and converted.

The Breakthrough Was Intent, Not the Advert

Search advertising was not the first form of advertising sold against context. Newspapers had long placed classified adverts beside relevant sections. Directories organised businesses around the categories people needed. Retailers understood that a customer standing in a shop behaved differently from a person sitting at home with no immediate intention to buy.

Google made that context extraordinarily specific, immediate and scalable.

The query tells the platform what the user is trying to resolve at that moment. Advertisers can then compete for visibility around the language of the need rather than only around broad demographic assumptions.

Google launched AdWords in 2000. The early product has since evolved through conversion tracking, keyword matching, automated bidding, shopping formats, Performance Max and a great many interface changes that have occasionally made experienced practitioners wonder whether a useful setting has been moved, renamed or simply invited to spend more money.

But the commercial engine has remained recognisable: identify a query, assess its likely value, auction access to the results page and charge when the user engages.

Importantly, the highest bidder does not automatically receive the best position. Google says Ad Rank incorporates the bid alongside auction-time quality signals such as expected click-through rate, ad relevance and landing-page experience. That helps protect the usefulness of the results page. A system that showed only the advertiser willing to pay most would eventually become a rather expensive way to produce poor answers.

Why “Raw Dog Food” Worked

When I took greater control of the Google Ads account at Paleo Ridge, I was able to make substantial changes that produced clear improvements. Measurement had advanced, the account contained more usable evidence and we could see much more directly what effective changes were doing.

The central advantage was not a mysterious advertising trick. Customers were already searching for raw dog food.

That category language mattered. We understood the terms people used, the questions behind them and the relationship between paid search and our SEO work. The advert, the keyword and the landing page could therefore form a coherent route from the search to a relevant answer.

Paid and organic search worked together because both were rooted in the same understanding of the customer. The SEO work helped us learn how people described the category. The paid activity gave us faster feedback and controlled visibility. Neither discipline was improved by pretending the other did not exist.

This is also why Google Trends can be so useful to marketers. Search data does not reveal every motive, but it provides unusually direct evidence of how attention and language change.

The campaign worked because the demand, proposition and search language aligned. Google did not persuade a previously indifferent public to wake up longing for frozen dog food. It helped us reach people whose behaviour had already made that interest visible.

Google Ads Does Not Create the Queue

Black Friday makes the distinction particularly obvious.

During the period around Black Friday, many consumers become more willing to search, compare and buy. Retail coverage increases. Brands send emails, publish offers, run social campaigns and create urgency. Friends discuss deals. Customers delay purchases in anticipation of discounts. Commercial intent rises across the market.

Search advertising becomes more important because more people are standing near the top of the Intent Ladder.

A paid search campaign can capture that surge. It can improve the chance that one brand is selected instead of another. It can make a strong offer visible at exactly the right moment. It does not deserve sole credit for creating the event, the category demand, the brand familiarity or the customer’s decision to shop.

The strongest marketing systems do all three. A business that funds only the final step may become very efficient at harvesting demand while slowly reducing the amount available to harvest.

Where the Money Leaks Out

Google Ads can be precise. It can also spend a budget with admirable punctuality while everybody assumes the automation is taking care of things.

Negative keywords are one of the simplest safeguards. They stop ads appearing against searches that contain irrelevant or misleading terms. Without regular attention, a business can pay for traffic from people who are clearly looking for something else.

Search terms also change. Campaigns change. Offers change. A new-customer promotion ends, but the old advert remains active because somebody updated the landing page and forgot the copy in the account. The result is not merely wasted spend. It can create disappointment and undermine trust.

Dynamic keyword insertion requires similar care. The feature can place a keyword from an advertiser’s ad group into the advert, helping the copy appear more closely related to the search. It can also produce misleading results when advertisers bid on competitors’ brand names or build campaigns without sufficient controls.

I have seen adverts from other businesses display the Paleo Ridge name in their copy. To a customer, that can look like a Paleo Ridge advert even when it is not. My usual response has been to contact the brand and ask it to correct the problem before reporting it to Google. That tends to be the most constructive way to work, particularly when the mistake has been created by a setting rather than a deliberate attempt to mislead.

The Attribution Trap

Search has a natural advantage in attribution because it often appears near the end of the journey.

A customer may first hear about a brand from a friend, see its packaging, read an article, encounter it at an event, notice several social posts and then search for the brand name. The paid search click is measurable and close to the sale, so it receives a large share of the credit.

That is useful evidence. It is not the complete causal story.

The same applies to non-brand searches. The customer who searches for a category has already acquired the language to describe the need. Somebody helped create or spread that category. Product experience, cultural change, word of mouth, distribution and previous marketing may all have moved the customer up the ladder before Google recorded the final few steps.

This does not make paid search less valuable. It makes its role clearer.

Google monetised the lower, more commercially valuable rungs of the Intent Ladder. Marketers still need other activity to move people onto it in the first place.

This is one example of the tension between marketing thought and marketing practice. The principle is easy to state. In a live budget meeting, the channel with a visible return often has a more persuasive spreadsheet than the activity building future demand.

How Much Control Should Marketers Hand Back to Google?

Google’s direction has increasingly favoured automation. Advertisers are encouraged to use broader matching, automated bidding, Performance Max and AI-assisted campaign tools. The platform argues that its systems can assess more signals, respond faster and find opportunities that manual management would miss.

That argument is not absurd. A human cannot manually calculate every device, location, time, audience and auction signal at the speed or scale of Google’s systems.

My own experience of Google automation has nevertheless been more negative than positive. I prefer to retain control, understand why money is being spent and see the relationship between the search, the advert and the landing page.

There is also a structural tension. Google supplies the marketplace, recommends how the advertiser should use it, automates many of the decisions and receives more revenue when more money is spent. That does not mean every recommendation is wrong. It does mean marketers should not outsource scrutiny to the party selling the clicks.

The sensible response is not to reject automation entirely. It is to give it boundaries: clear commercial goals, reliable conversion data, exclusions, brand controls, realistic budgets and regular human review.

Automation should earn authority through evidence. It should not receive authority because the interface contains a brightly coloured recommendation.

AI Search Changes the Shape of Intent

Google’s next challenge is that the search box itself is changing.

Traditional search turns a query into a page of links. AI search can interpret a longer problem, assemble an answer, compare options and increasingly take actions on the user’s behalf. Google described its 2026 changes as the biggest upgrade to the search box in more than 25 years, including agent-like capabilities and more personalised answers.

That creates a difficult commercial problem. If an AI system answers more of the question itself, fewer users may need to visit the traditional list of results. If an AI agent researches and acts for the customer, intent may be expressed in a long conversation rather than a neat keyword.

Google therefore has to adapt both discovery and advertising at the same time. It must keep search useful enough for people to trust, create formats advertisers can understand and measure, and protect the revenue engine that funds much of the company.

This is not the end of search intent. If anything, a detailed conversation can reveal more intent than a two-word query. The question is who will interpret that intent, which businesses will be allowed into the answer and how clearly commercial influence will be identified.

Google has enormous distribution, data, advertiser relationships and technical capability. It is not starting from behind in any ordinary sense. But it is playing catch-up with a change that threatens the familiar shape of its own most successful product.

The Most Valuable Moment in Marketing

My experience of Google Ads has moved from small budgets and limited attribution at Fairthorne Manor to a channel capable of playing a critical role in a direct-to-consumer business.

The tools became better. Measurement improved. The accounts became more sophisticated. The essential commercial principle did not change.

Google became an advertising empire because it learned to identify the moment when an internal need becomes an external signal. The company did not need to know everything about a person. It needed to know what that person had just asked for—and to persuade businesses that appearing beside the answer was worth bidding on.

For marketers, paid search deserves serious investment when the category, proposition and economics support it. It also deserves disciplined account management, scepticism about attribution and a clear understanding of what the channel can and cannot do.

Search can catch a customer at the top of the Intent Ladder.

Marketing still has to give them a reason to start climbing.

Frequently Asked Questions

What is search intent?

Search intent is the purpose behind a query. A person may be trying to learn, compare options, reach a particular website or complete a transaction. Commercial value tends to rise as the query becomes more specific and closer to action.

Does Google Ads create demand?

It can influence choice and make an offer visible, but paid search is usually strongest at capturing existing or developing demand. Brand building, product experience, word of mouth, content and wider culture often help create the need and language that lead to the search.

Why are negative keywords important?

Negative keywords prevent ads from appearing for irrelevant searches. They reduce wasted spend, protect the accuracy of the message and help advertisers concentrate budget on queries that fit the product and customer.

Is Google Ads fully automated?

Google offers extensive automation for matching, bidding, creative and campaign management. Human oversight remains important for strategy, data quality, exclusions, brand safety, promotion accuracy and the commercial interpretation of results.

How will AI search affect advertising?

AI search may turn short queries into longer conversations and answers assembled directly by the platform. Advertising will need to fit those journeys without weakening trust, while marketers will need new ways to understand visibility, influence and attribution.
