Can you grow on paid ads alone? How SEO, GEO and advertising work together

Growing on paid ads alone works in the short term, but it is not healthy in the long run. Ads bring visitors for as long as the budget flows; the day it stops, the visitors stop too, and it is the auction, not you, that sets the price. SEO and GEO, on the other hand, make your website lastingly visible in Google and in AI answers. The two are not rivals: according to Google's own measurement, a business that is strong organically needs less advertising for the same result. The real question is not "SEO or PPC?" but "how much of each, and when?".

What is the risk of relying on paid ads alone?

A business that relies on paid ads alone has its entire flow of customers attached to a single tap. While it is running, nothing seems wrong. The risks show up when the budget shrinks, a platform changes its rules or new competitors arrive. Four of them matter most.

Traffic depends on budget. You pay for every visit that comes through an ad. In the month you cut the budget, those visitors disappear. After a year of advertising, what you are left with is the history in your ad account; nothing of lasting value has built up on your website.

Someone else sets the price. Google Ads, Meta, TikTok and ChatGPT ads all run on auctions. When a new competitor enters your market or demand rises in peak season, your cost per click rises with it. Even on the same budget, you then get fewer visitors.

Dependence on one platform. A restricted ad account, a policy change or a new measurement method can hit your entire flow of customers overnight. Apple's tracking prompt on iPhones, introduced in 2021, made targeting and measurement of Instagram and Facebook ads noticeably harder for many businesses. Advertisers were not consulted.

Measurement depends on consent. In the UK and the EU, measuring and personalising advertising relies on visitors agreeing to cookies and tracking. A business that steers all of its demand through ads is making budget decisions on data that grows patchier with every declined consent banner.

What do Google Ads, Meta, TikTok and ChatGPT ads do well, and what not?

Each advertising platform reaches buyers at a different moment. Rather than declaring one of them the best, it pays to know which job each does well.

Google Ads: reaching customers who are searching

Running Google Ads means being visible at the exact moment someone searches. A person typing "emergency roofer" or "accountant for freelancers" has a clear intention. Google Ads captures that existing demand and delivers results quickly. That is also its limit: it only sells what people are already searching for. A new product that nobody knows about yet is hard to launch with search ads. And the price depends on your competitors' bids and on the quality of your page.

Meta ads: discovery on Instagram and Facebook

Instagram ads and Facebook ads reach people who are not searching but might be interested. They are strong for products that sell on visuals, for new brands, and for campaigns aimed at a clearly defined audience. The limit is that the person is rarely ready to buy at that moment. The ad creates demand; the decision is usually made later and through another channel. Creative also wears out quickly: show the same ad to the same audience for long enough and it stops working.

TikTok ads: video, and now search

TikTok ads suit younger audiences and products that can be explained in short videos. TikTok now sells ads not only in the feed but also in its search results: there are keyword-based search campaigns, and feed ads are shown in search results by default. TikTok is becoming a search channel in its own right. The limits are the effort of producing new videos constantly, and the fact that not every offer fits the format.

ChatGPT ads: a new channel

ChatGPT ads have been rolling out country by country during 2026, starting in the UK in June and reaching much of Europe by late summer, with self-serve buying through OpenAI's Ads Manager. The ads appear in the chat, separate from the answer and labelled as sponsored. The rules OpenAI has published matter: users on the Plus, Pro and Business plans see no ads, and neither do users under 18; ads do not appear in conversations about health, mental health or politics; advertisers cannot see chats and receive only aggregated performance data. The channel is new and reliable benchmarks are scarce. Because paying subscribers see no ads, in some sectors part of your decision-makers may never see them at all.

Platform	The buyer's moment	Strength	Limit
Google Ads	Searching, close to a decision	Capturing existing demand	Only sells what is searched for; auction pricing
Meta (Instagram, Facebook)	Not searching, scrolling	Creating demand, building awareness	Decision usually later, elsewhere
TikTok	Watching videos, increasingly searching	Younger audiences, explainable products	Constant video production
ChatGPT	Asking questions, researching	Visible at the moment of research	New; subscribers see no ads

Can ChatGPT ads get your business into the answer?

No. The first of OpenAI's advertising principles is answer independence: ads do not influence what ChatGPT answers, always sit separately from it and are clearly labelled. Advertising buys you the space next to the answer, not the answer.

That raises a new question for businesses. If someone asks ChatGPT "Which agency builds multilingual websites for manufacturers?", you can appear in two places. The first is the ad space: if you pay, you appear there when relevant. The second is the answer itself: ChatGPT cites you as a source or recommends you. The second cannot be bought. The way in is a website and content that AI can find, understand and quote. That is what GEO means; what it takes in practice is set out in our guide to showing up in AI search.

For buyers, the difference is significant. A recommendation marked as sponsored does not carry the same trust as a name the AI mentions in its own answer. It was no different in classic search: appearing in the ad space and appearing in the organic results are two different things, and both have their place.

How do SEO and GEO lower the cost of your advertising?

In two ways: by reducing how much advertising you need, and by making the advertising itself cheaper. Both rest on Google's own documentation.

First: organic strength changes what ads add. In 2011, Google analysed more than 400 experiments in which advertisers paused their search ads. On average, 89 per cent of the lost ad clicks were not replaced by organic clicks; in other words, the ads genuinely brought extra visits. A follow-up analysis in 2012 showed that this share depends heavily on organic position:

Advertiser's organic position	Share of ad clicks that are genuinely extra
Position 1	50 per cent
Positions 2 to 4	82 per cent
Below position 4	96 per cent

According to the same analysis, 66 per cent of ad clicks happened on searches where the advertiser had no organic result on the first page at all. The conclusion is clear: on searches where you are strong organically, part of your ad spend pays for visits that would have come anyway. Where you are weak organically, you pay for every visit. The data is more than ten years old and results pages look different today. It is still the most comprehensive measurement Google has published, and the direction has not changed.

Second: good pages make ads cheaper. Google Ads does not decide where your ad appears and what it costs on your bid alone. According to Google's description of the auction, the quality of the ad and of the landing page also counts; a relevant, high-quality ad can win a higher position at a lower cost than a competitor with a higher bid. One of the three components of Quality Score is landing page experience itself: how relevant and useful the page is to people who click the ad. Meta's auction likewise weighs the quality of the ad and how likely people are to respond to it, alongside the bid.

The work you do for SEO, meaning a clear page for each service, a direct answer to the question, a fast page that works properly on mobile, is also the landing page for your ads. The same page welcomes organic visitors and lowers the price of your advertising.

When is paid advertising alone the right choice?

In some situations, paid advertising alone is the right choice, sometimes the only sensible one. That needs saying, because prescribing the same recipe to every business would not be honest.

• A new business or a new product. Until there is an organic base, advertising brings the first customers. SEO starts alongside it but should not be expected to produce sales in the first months.
• Short campaigns. A trade fair, a seasonal offer, an event. For something that lasts a few weeks, permanent pages are not worth building.
• Testing demand. If you do not know which service or search term actually sells, a small ad budget will show you within weeks. That data later decides which SEO pages to write.
• Products nobody searches for. If people do not know your product exists, there is no search. Demand then comes from Instagram, Facebook or TikTok ads.

It is just as clear when paid ads alone are unhealthy: a business has done the same work for years, its customers search for exactly that, and yet all of its demand comes from ads. Every month it is paying rent on a place it could own.

How should you split your budget?

There is no percentage that fits every business, and quoting one while implying it rests on measurement would not be honest. The right split depends on the stage a business is at. What stays the same is that advertising and SEO feed each other: advertising buys data quickly, and SEO turns that data into lasting pages.

1. Starting out. The weight is on advertising. At the same time, the website's foundations are built: a page for each service, measurement set up with consent, indexing in Google and Bing. Without these foundations, neither SEO nor advertising works efficiently.
2. Learning. The search terms report in Google Ads shows which queries actually bring customers. Lasting pages and content are written for exactly those queries. This is also where GEO begins: content that clearly answers the questions customers would put to an AI.
3. Balancing. On searches where you have become strong organically, advertising is reduced in controlled tests; the budget moves to searches where you remain weak organically and to channels that create demand.
4. Maturity. Advertising is used for new products, campaigns and the most competitive searches. The bulk of demand comes from organic search and AI answers.

The step most often skipped is the second. The search term data that builds up in the ad account over months never reaches the SEO plan in most businesses.

How do you measure what advertising really adds?

The number of sales in your ad dashboard is not the same as the number of sales advertising actually caused. Some of the people who click an ad would have found you without it. To see the real contribution:

• A controlled pause test. A small version of the method Google used in its research: pause ads in one region or for a few weeks and compare with other regions or periods. You will see how much of the demand organic search picks up.
• Brand searches. If you already rank first organically for searches on your own company name, ads on those searches may add little. If a competitor bids on your name, the picture changes; test that too.
• Channel comparison. In Google Analytics, compare the enquiry rate of visitors from organic search, advertising and AI sources side by side.
• Search terms report. Check regularly which queries your ads spend money on and which of them bring enquiries.
• How did you hear about us? Ask this in your contact form or first call. Whatever the dashboards say, the customer's own answer is the most honest measure.

When advertising, SEO and AI visibility are handled by different agencies in separate reports, nobody asks these questions; each report makes its own channel look good. That is why our SEO and performance marketing service brings all three together in one view: so you can see in one place where each enquiry comes from and where the next pound should go.
