Advertising in AI Answers: What Ads in ChatGPT, Perplexity, and Google AI Mode Mean for SMBs

For decades, the logic of online advertising was simple: users type in a search query, get a list of blue links, and the ads sit right at the top. In 2026, that model is getting competition. Increasingly, an AI steps in between question and answer, formulating a ready-made response directly instead of offering ten links. And it is precisely into this AI answer that the first ads are now moving.

For advertisers, this is a tectonic shift: visibility is no longer decided by a position in a results list, but by whether a brand becomes part of the generated answer. In this article, we break down where advertising in AI answers is real today, where it is still being tested, and what this concretely means for small and medium-sized businesses.

1. Advertising Moves Into the AI Answer

Classic search advertising lives off the click: an ad leads from the results list to a landing page. In an AI answer, that results list is often gone altogether. The user reads a summarized answer and clicks through less often. Anyone who wants to be visible here must either be cited organically or become part of the answer environment as a paid placement.

2026 is the year the major providers are rolling out exactly these paid placements. All of them follow the same principle: ads should not distort the actual answer, but appear clearly labeled alongside or beneath it. Competition is thus shifting from "Who ranks at the top?" to "Who becomes part of the conversation?"

2. The 2026 Market Picture: Where Users Ask Questions Today

Before getting to advertising, it's worth taking a sober look at reach. Because as loudly as AI search is being discussed, the current balance of power is quite clear: classic Google Search still sends by far the largest share of referral traffic. At the same time, the use of AI assistants for information queries is growing rapidly.

ChatGPT dominates the AI assistant market, while Perplexity, a pure-play AI search engine, is catching up with triple-digit growth rates. Google, meanwhile, is shifting its own reach – built up over years – toward AI answers, taking advertising budgets right along with it. The chart below shows the rough distribution of the AI assistant market.

3. ChatGPT Ads: OpenAI's New Advertising Platform

The biggest turning point came on February 9, 2026: OpenAI launched advertising in ChatGPT – initially for US users on the free plans and ChatGPT Go. The ads appear as clearly labeled, subtly shaded boxes at the end of an answer. OpenAI emphasizes that the actual answer remains unaffected by this – a direct counter to concerns that AI answers could become for sale.

3.1 How the Targeting Works

Instead of classic keyword booking, OpenAI relies on contextual matching: what matters is the current conversation topic, the chat history so far, and previous ad interactions. Ads run where they fit the conversation – for example, a product recommendation when the user is already researching a given topic.

3.2 Access and Cost

Since May 2026, advertisers have been booking through the self-service OpenAI Ads Manager with CPC or CPM bids and no minimum budget – the barrier to entry is deliberately low. Paid plans such as ChatGPT Plus, Team, and Enterprise remain ad-free for now. The expansion beyond the US begins with pilot markets such as Canada, Australia, and New Zealand; German-speaking markets are not yet included.

4. Perplexity and Comet: Ads in the Answer Engine

Perplexity was early: as far back as November 2024, the AI search engine was the first major platform to test sponsored follow-up questions and sidebar ads. The model remained bumpy, however – since October 2025, Perplexity has stopped accepting new advertising customers and is restructuring its ad business.

More interesting is the strategic bet on its own AI browser, Comet: it integrates the Perplexity assistant directly into browsing and can take on tasks like filling out forms or comparing products. Whether ads will come there is disputed – according to Perplexity, ads for Comet are currently not on the roadmap, while at the same time there is speculation about highly personalized advertising based on user behavior. For marketers, this means: in 2026, Perplexity is primarily an organic visibility channel, with hardly any plannable ad placements.

5. Google AI Mode: Four New Gemini Ad Formats

Google still holds the biggest lever – simply because of its reach. AI Mode, Google's AI answer interface in Search, passed the mark of around one billion monthly users in 2026. At Google Marketing Live 2026, Google unveiled four new Gemini-powered ad formats for AI Mode – initially being tested in the US:

• Conversational Discovery Ads: answer a specific user question directly within the AI answer, with product-specific text that Gemini generates in real time.
• Highlighted Answers: suitable ads appear as a recommendation within list-style AI answers – position depends on relevance, not on the bid alone.
• AI-Powered Shopping Ads: Gemini surfaces the most relevant products and automatically writes a short explanation of why a product might be a good fit.
• Business Agent for Leads: a Gemini chat agent trained on a company's own website, letting users clarify questions directly within the ad before they leave the search.

Based on past experience with Google innovations like these, the rollout to Europe typically follows within six to twelve months. We take a deeper look at how AI is transforming the Google advertising world as a whole in our article Google AI Update: The New Generation of Advertising.

6. What Makes AI Advertising Different

Three characteristics fundamentally distinguish advertising in AI answers from classic search ads:

• Context instead of keyword: triggered by the conversation topic and intent, not by an exactly booked search phrase. This rewards good product data and clear positioning over pure keyword lists.
• Dialogue instead of click: formats such as business agents or conversational ads keep the user in the conversation. The ad becomes an advisor, not just a signpost.
• Proximity to the answer instead of a results list: the ad sits directly alongside the generated answer. Trust and labeling therefore become the decisive factor – advertising that is too intrusive endangers acceptance of the AI itself.

The same principle applies on the organic side: anyone who wants to be cited in AI answers must be structured, well-evidenced, and clearly findable. That is the core of Generative Engine Optimization (GEO) – and the foundation that paid AI formats later build on as well.

7. What This Means for SMBs Right Now

The honest assessment for small and medium-sized businesses: knee-jerk action is not necessary. Most of the new ad formats are still US tests, and the bulk of reach still lies with classic Google Search. Anyone considering shifting budget today should not do so because of headlines, but based on data.

At the same time, doing nothing is not an option, because the groundwork for AI visibility takes lead time. Three things pay off twice – organically today, and for paid AI formats tomorrow:

7.1 Becoming Findable for AI Answers

Structured data, clean product information, and clearly formulated answers to real customer questions determine whether an AI cites your brand. This is the organic groundwork – and the foundation on which AI-Powered Shopping Ads or Highlighted Answers can take hold at all. We show how to do this systematically in our article on SGE and AI Overviews.

7.2 Building First-Party Data

Contextual targeting and business agents thrive on your own data: website content, product catalogs, FAQs, and customer lists. Anyone who maintains this foundation can feed AI formats precisely later on – and is simultaneously less dependent on third-party cookies.

7.3 Test Small, As Soon As It's Available

Because the barriers to entry – for example, no minimum budget on ChatGPT – are low, a controlled test is worthwhile as soon as the formats go live in Europe. We make exactly these levers systematically usable within AI Performance Marketing.

8. Checklist: Preparing for AI Advertising

• Check visibility: test whether and how ChatGPT, Perplexity, and Google AI Mode mention your company today.
• Expand structured data: prepare schema markup, product data, and FAQs so AI systems can read them cleanly.
• Deliver answers to customer questions: content that precisely answers concrete questions gets cited more often.
• Collect first-party data: maintain newsletters, customer accounts, and product catalogs as a data foundation for future AI campaigns.
• Plan a budget reserve: keep a small test budget ready to try out AI formats in a controlled way once they launch in the EU.
• Take labeling seriously: maintain transparency in your own AI-adjacent formats – trust is the hardest currency in AI answers.

9. Conclusion: Visibility Is Being Redefined

2026 marks the point at which advertising leaves the results list and moves into the AI answer. ChatGPT leads the way with labeled ads, Google brings scale with AI Mode, and Perplexity shows both the opportunities and the limits of the answer-engine model. Much of it is still US testing – but the direction is clear.

For SMBs, the right response is neither panic nor waiting, but preparation: companies that become organically visible in AI answers now and sharpen their data foundation will have a head start once the paid formats reach their markets. Visibility is no longer a ranking – it's the question of whether an AI recommends you.

10. FAQ: The Most Important Questions About Ads in AI Answers

Can you already run ads in ChatGPT?

Yes. OpenAI launched ads in ChatGPT on February 9, 2026, initially for US users on the Free and Go plans. Ads appear as clearly labeled, subtly shaded boxes at the end of an answer and do not influence the answer itself. Advertisers book through the self-service OpenAI Ads Manager with CPC or CPM bids and no minimum budget. Paid plans such as Plus, Team, and Enterprise remain ad-free for now. The expansion starts with pilot markets such as Canada, Australia, and New Zealand.

Does Perplexity have advertising?

Perplexity was the first major AI search engine to test sponsored follow-up questions and sidebar ads, back in November 2024. Since October 2025, however, Perplexity has stopped accepting new advertising customers. According to Perplexity, ads are currently not on the roadmap for its AI browser, Comet. Perplexity therefore remains an important visibility channel, but for now it is hardly a plannable advertising channel.

What is Google AI Mode, and are there ads there?

AI Mode is Google's AI-powered answer interface in Search, reaching around one billion monthly users in 2026. At Google Marketing Live 2026, Google unveiled four new Gemini-powered ad formats for AI Mode: Conversational Discovery Ads, Highlighted Answers, AI-Powered Shopping Ads, and a Business Agent for leads. They are currently being tested in the US; based on past rollouts, the expansion to Europe typically follows within six to twelve months.

Does my company need to invest in AI advertising right now?

For most SMBs, there's no need for knee-jerk action, since the formats are still largely in US testing. What does make sense is laying the groundwork now: companies that build structured data, clean product information, first-party data, and a clear positioning for AI search will be ready the moment the formats go live in Europe – and already benefit today from better organic visibility in AI answers.
