Introduction

If you work in digital marketing, you’ll know already that a major shift is well underway. Search engines like Google, Yahoo, and Bing are no longer the only place people go for answers. Instead, more users are now asking LLMs like ChatGPT, Gemini, Claude, and Perplexity for help with everyday decisions.

This includes everything from booking a holiday to choosing software for their business. Such a move from traditional search engines to AI answer engines is set to be the biggest change in online behaviour since the rise of mobile.

But here’s the thing. Where people go, advertising eventually follows. And that is why AI ads in LLMs are currently being developed.

What is Artificial Intelligence?

Artificial intelligence (AI) is a technology that enables machines and computers to think, learn, and behave like humans. These systems are programmed to:

• Analyse data
• Recognise patterns
• Perform human tasks like understanding language, problem-solving, and recognising speech

It is a broad field that encompasses machine learning, deep learning, and other technologies. It can be used in a wide range of applications, including everything from virtual assistants to self-driving cars.

When speaking of artificial intelligence, Larry Page predicted it “would be the ultimate version of Google. The ultimate search engine that would understand everything on the web. It would understand exactly what you wanted, and it would give you the right thing.”

What Is AI Advertising?

AI advertising is a new category of digital advertising. It uses artificial intelligence to automate and optimise digital marketing campaigns. The aim is to make them more relevant, personalised and efficient to the target audience.

Through machine learning and data analysis, AI advertising:

• Understands consumer behaviour and intent
• Predicts future trends
• Automates tasks like ad creation, targeting, and placement

What are LLMs?

LLMs, or Large Language Models, are highly advanced AI programs. They are trained on massive amounts of text to understand and generate human-like language.

They can perform a wide range of “core” tasks, including:

• Generating text, such as blog posts, emails, reports, and creative content.
• Summarising long-form content into shorter summaries.
• Translating text from one language to another.
• Providing answers to general knowledge enquiries.
• Assisting developers in writing code, finding errors, and identifying security issues.

On a more advanced level, LLMs can also:

• Analyse and interpret large volumes of data for market research
• Recognise acts of fraud or cybersecurity threats.
• Understand and describe the content of images.
• Perform complex math and other logical operations.
• Break down complex tasks into smaller steps and create more adaptable plans to complete them.
• Create charts and graphs from data.

Many people think LLMs are a relatively new invention. However, its roots go back to the 1960s. Back then, MIT researcher Joseph Weizenbaum created the world’s first chatbot, “Eliza”. This signalled the start of research into NLP (natural language processing).

The “large” in its name refers to the enormous datasets and the trillions of parameters used for learning patterns in language.

The Rise of AI Answer Engines

Google launched in 1998 and, for the best part of 25 years, held a monopoly on how people searched for information. However, that has all changed now, thanks to the rise of AI Answer engines like ChatGPT, Gemini, Claude, and Perplexity.

It’s not that people have stopped using Google. Far from it, in fact. Currently, an estimated 14-16 billion searches are carried out every day. The most common search term is “YouTube”.

However, it’s more that people are dividing their time across multiple platforms. So, AI answer engines are becoming the first stop for everyday questions.

For example:

• ChatGPT answers everything from travel questions to hiring advice
• Gemini simplifies complex tasks with multimedia and real-time context
• Claude focuses on accuracy and trust
• Perplexity delivers fast, citation-driven results

Instead of browsing through long lists of websites that appear on the first few pages of Google, people are increasingly relying on a single, consolidated answer. Essentially, AI answer engines are becoming the go-to assistant for many user’s decision-making.

What does the rise of AI Answer Engines Mean for Marketers?

As more people turn to LLMs for answers, digital markets can tap into a massive opportunity. For instance:

1. The reach across ChatGPT, Gemini, Claude, Perplexity, Meta AI, and other niche LLMs is comfortably over 1 billion users. That’s much larger than most social media networks.
2. Unlike social platforms such as Facebook, X, TikTok, and Instagram, AI answer engines operate with intent. Users are specifically looking for help. They are not just aimlessly scrolling to pass the time.
3. ChatGPT alone is projected to generate US$25 billion in revenue by 2029. A large chunk of that is expected tol come from AI adverts.
4. Early adopters of AI advertising are likely to benefit from low costs and flexible placements.

It seems clear that we are standing at the start of the next major advertising cycle. That is why digital marketers should focus on developing strategies that improve their chances of being included in AI-generated answer results.

How Will AI Ads Work Inside LLMs?

AI ads will work very differently from the search and social ads you might be used to on Google and Facebook. Rather than showing ads alongside search results, AI answer engines will recommend businesses, products, or services within their generated responses.

Advertisers will essentially “teach” a language model their brand’s voice. Bids will determine the extent of this model’s influence on the final, contextually relevant output. This model enables ads to be seamlessly woven into user-LLM interactions. Subsequently, it will deliver more integrated, contextual, and personalised experiences at the moment of intent.

What’s the Difference Between AI Ads and Traditional Search or Social Ads?

Traditional search or social ads are often perceived as interruptions. That is because they typically sit beside, above, or are squeezed between content. AI ads, on the other hand, sit inside the experience.

Essentially, they’re woven into the conversation or the answer a user is already asking for. So, instead of bidding on keywords or chasing attention in a feed, advertisers are looking to step into a moment of intent when someone is actively looking for guidance.

You might see a generated paragraph with a gentle brand mention. Or an AI might surface recommended tools or service providers based on what it already knows about your query. This new format blends content and promotion in a more natural, conversational way.

AI Ads vs Traditional Search Ads vs Social Media Ads (Quick Comparison)

If you are still unsure about the differences between AI ads, traditional search ads, and social media ads, here is a quick comparison guide.

What Will AI Ads Be Like on Specific LLM Platforms?

AI adverts do not currently feature on most LLMs. However, many experts expect them to be rolled out in 2026.

Here is an overview of what they might look like on ChatGPT, Google Gemini, Claude, and Perplexity.

ChatGPT Advertising

ChatGPT is in line to become the biggest new advertising channel since Google Ads. OpenAI hasn’t launched its full ad platform yet. But all signs point to a major rollout in 2026.

Here are five reasons why:

1. They’re hiring an impressive team of tech specialists from Google, Meta, X, Amazon, and Snap. They also recently added Andrej Karpathy, the former head of Autopilot at Tesla, to their ranks.
2. They’re testing sponsored recommendations in limited environments.
3. They’ve already said publicly that monetisation through advertising is part of their long-term strategy.
4. ChatGPT averages around 800 million users every week. 54–57% of whom are aged 18-34. This is a goldmine for brands looking to reach tech-savvy consumers with decent spending power.
5. ChatGPT is projected to generate US$25 billion in revenue by 2029 if it rolls out AI adverts.

What will ChatGPT Ads look like?

You can expect ChatGPT ads to include a mix of:

• Sponsored answers
• Sponsored suggestions
• Conversational ad units

They will appear when users ask about specific products or industries.

A big advantage ChatGPT has is that it already knows how people phrase questions and what they care about. That makes it a powerful medium for AI-powered ad targeting.

For example, imagine someone asking, “What’s the best CRM for a small business?”

ChatGPT could respond with a helpful explanation and a sponsored CRM recommendation.

What will ChatGPT Ads cost?

It is likely that beta access will be introduced to their enterprise partners first. When it is, the cost may follow a cost-per-answer model. This will involve advertisers paying per generated response that includes their brand.

Predictive advertising will most probably be used to decide which brands are shown. However, as ChatGPT relies on entity-based optimisation, those with strong digital signals should have a natural advantage.

Google Gemini Ads

Google has been open about its plans to bring advertising into the Gemini ecosystem. Sundar Pichai, CEO of Google, has already confirmed that the multinational tech giant is exploring “native ad concepts” inside Gemini’s conversational interface. This is the strongest signal yet that a full AI ad platform is on the way.

Given Google’s long history of monetising attention at scale, it’s no surprise they’re preparing Gemini to become a major revenue engine. What’s interesting is how seamlessly they’ll be able to fold it into the products advertisers already use every day.

Right now, Gemini’s ad system is still in development, but Google has said repeatedly that AI is central to its long-term strategy. Currently, they’ve invested more than $75 billion in AI infrastructure, models, and research. So, the next logical step is to turn Gemini into an ad-supported assistant.

While the exact launch timing isn’t confirmed, most industry observers expect Google to bring native AI ads to market sometime in 2026. As a rule, Google tends to move cautiously with advertising changes, especially when they’re tied to search behaviour. But the direction is clear.

What will Google Gemini Ads look like?

Gemini’s integration with Search, YouTube, and Google Workspace means Google can personalise ad experiences across multiple touchpoints.

AI ads seem set to appear inside AI-powered search results or conversational responses. They may also connect directly to your existing Google Ads account. This should make it easier for advertisers to expand into AI formats without having to learn an entirely new system.

Google has always been strong at paid placements. But with Gemini, you can expect the next evolution of contextual ads. Generative AI ads will not replace Google Ads. However, they will complement them.

Perplexity Advertising

Perplexity was the first major AI answer engine to jump into paid advertising. Launching its ad platform in November 2024. While other AI companies are still sketching out concepts or quietly running internal tests, Perplexity has already put real ads in front of real users.

The platform is live and running with a small group of launch partners. Brands like Indeed, Whole Foods Market, Universal McCann, and PMG were among the first to test Perplexity’s system.

What are Perplexity’s AI Ads like?

Perplexity’s ad formats are simple, clean, and clearly designed to preserve the experience users expect from the platform. They may appear as:

• Sponsored citations
• Recommended tools
• Product suggestions
• Business listings within answer summaries

The primary format is sponsored follow-up questions. They appear after Perplexity provides an answer. These follow-ups act as a natural next step in the conversation.

For example, if a user asks about job hunting, the sponsored prompt might guide them to explore roles on the employment search website Indeed.

Likewise, if they ask for dinner recipes, they may see a follow-up attached to Whole Foods or a related partner.

Claude Ads

Claude by Anthropic is the outlier among the major AI platforms because, so far, it hasn’t confirmed any ad plans. Instead, they’ve kept their roadmap tightly focused on the three pillars of model development, enterprise safety, and large-scale API partnerships.

However, with all their major LLM competitors moving toward monetised recommendation systems, it’s reasonable to expect that Claude will eventually explore some form of advertising or brand integration.

What Will Claudes AI Ads Be Like?

Claude by Anthropic has earned a reputation for accuracy, clarity, and reliable reasoning. It attracts a more technical, business-oriented audience than other LLM platforms. Its strongest adoption comes from enterprise teams, developers, and organisations running large volumes of API calls.

For this reason, if Claude does launch AI ads, it could be good news for businesses across industries such as SaaS, consulting, finance, education, and enterprise software. Any potential ad products will likely lean toward enterprise-focused advertising rather than consumer retail.

This might take the form of promoting:

• Tools
• Software
• Infrastructure providers
• Cloud platforms
• Security products
• Other B2B categories that naturally fit into the workflows of people using Claude for work

Why Should I Advertise on LLMs?

You might be wondering why you should build an advertising strategy around AI Advertising on LLMs. Here are three compelling reasons to do so.

1. Scalability

AI advertising offers incredible potential for scaling. This is because potential ad revenue scales with the growth of the user base.

Unlike with subscriptions, there is no ceiling. So there is no limit to your potential ROI.

2. Huge Target Audience

Most LLMs have free versions, which is why millions of people use them. For companies that advertise on LLM search engines, it enables them to reach a massive pool of potential customers in a way that is not intrusive.

3. Data-Driven Refinement

Often, there is some guesswork involved in developing search or social media advertising campaigns. However, with AI Ads, marketers can deliver campaigns that are based on user interactions. This makes them feel more relevant to users and should result in higher conversion rates.

What Businesses Will Benefit Most From AI Ads?

It’s fair to say that many companies stand to gain something from developing a strategy around AI advertising. However, some may do so more than others.

Those who operate in industries where users rely heavily on research and recommendations might enjoy good success. This includes:

• Finance
• Travel
• SaaS
• Home services
• Healthcare
• Education
• Professional services
• Insurance
• Real estate
• Legal

This is not an exclusive list. But as AI ads provide thoughtful and personalised suggestions, its fair to assume that industries which are defined by complex decisions or high-trust requirements will have the most to benefit.

6 Ways Your Business Can Prepare for AI Ads on LLMs

AI ads on LLMs are inevitable. So, instead of being afraid of change you should embrace it. Preparing for them now will gives your business a serious head start once paid placements fully land in ChatGPT, Gemini, Claude and Perplexity.

These platforms are already shaping how people search, compare and make decisions. Therefore, the groundwork you put in today will directly influence how often your brand gets recommended tomorrow.

Here are six practical steps you can take to build your visibility, strengthen your entity and position your business as an authority LLMs will want to reference.

1. Build Strong Entity Signals Across the Web

It is important to recognise that LLMs depend on entities and not keywords. They need to do this to understand who you are, what you offer and when you’re relevant.

That means your business needs to provide consistent information across all major directories, review platforms and social profiles. So the first thing you should do is make sure you check the following all read the same.

• Company name
• Business address
• Key services
• Pricing descriptions
• Product details

AI models reward clarity and penalise confusion. Therefore, you should make sure everything matches. The cleaner your entity looks, the easier it will be for an LLM to identify your brand as a suitable recommendation.

2. Create Deep, Helpful Content Hubs

Generative models prefer pages that show depth, authority and topic expertise. If your content is thin or scattered, AI engines are less likely to reference it.

Start with keyword research to build clusters around your core topics. This should involve producing:

• Practical “how-to” content
• Detailed guides
• Comparison pieces
• FAQs
• Media explainers that answer the exact questions your customers ask

The stronger you make your content hubs, the easier it will be for AI engines to surface your brand in both organic and paid contexts.

3. Optimise Your Content for Answer Engines

Answer Engine Optimisation (AEO) is becoming just as important as SEO. That is why it is important to do the following:

• Chunk your content into short and standalone sections
• Use clear headings
• Explain concepts in simple steps (with good visuals)
• Write compelling meta title’s and descriptions and provide direct answers (where possible) in the first sentence of any content

This structure will help AI systems extract meaning cleanly. It will also increase the likelihood of your content being cited or referenced.

4. Strengthen Your Trust Signals

AI models use trust cues to decide which brands to suggest in its results. This includes metrics like reviews, sentiment, consistency and quality. To strengthen your cues:

• Encourage reviews
• Reply to feedback
• Maintain transparent pricing
• Update your service pages regularly
• Add case studies and testimonials

LLMs also look for real-world proof that your business delivers what it promises. Subsequently, the more trust signals you have, the more credible you will appear through the lens of an LLM.

5. Monitor How Often AI Models Mention Your Brand Now

Type your brand name and services into ChatGPT, Gemini, Claude and Perplexity. Then watch how they describe your business. This can be an excellent form of “AI visibility tracking.”

If the responses are incomplete or inaccurate, you now know where to focus your improvements. Over time, these signals will influence how ready your brand is for paid placements and conversational advertising.

6. Prepare a Testing Budget

Most LLMs will roll out their AI ads gradually. When they do, advertisers who jump on board early will benefit from lower competition and cheaper placements.

When preparing for the financial year starting on July 2026, it is worth setting aside a small testing budget now. This will ensure you are ready to pounce the moment beta access opens.

Final Thoughts

AI advertising represents one of the biggest shifts in digital marketing in more than a decade. So, when ChatGPT, Gemini, Claude, and Perplexity roll out AI ads, businesses will need to be ready.

Those who prepare now will see the biggest gains. That is why we recommend focusing on:

• Building strong content
• Strengthening your digital footprint
• Improving your entity signals
• Positioning your brand to ready for AI advertising on LLMs
