OpenAI Ads vs Google Ads: what are the differences between advertising on ChatGPT and Google?

For more than two decades, Google has been at the centre of digital advertising. Companies across all industries have learned to compete through keywords, paid ads and SEO strategies to appear at the exact moment when someone was searching for a solution.

The logic was simple: a person had a need, typed a search query into Google, and brands competed for that opportunity through the results displayed.

This model completely transformed digital marketing. Google Ads became one of the most important advertising platforms in the world because it managed to connect search intent with commercial opportunity. When someone searched for “buy laptop”, “best management software” or “digital marketing agency”, they were showing a clear intention and companies could present a solution at that exact moment.

But the way people search for information is changing.

With the growth of generative Artificial Intelligence, a new form of digital discovery has emerged based on conversations. Instead of typing only keywords, users have started explaining problems, asking for recommendations, comparing alternatives and seeking guidance before making decisions.

This is the context where OpenAI Ads and ChatGPT Ads are emerging.

The comparison between OpenAI Ads vs Google Ads is not simply a difference between two advertising platforms. It represents a change in the way brands can be discovered by consumers.

Google revolutionised keyword-based search.

ChatGPT is creating a new era based on context.

Google Ads and OpenAI Ads: two different ways of capturing intent

The main difference between Google Ads and OpenAI Ads lies in the moment when the brand appears in front of the user.

With Google Ads, advertising usually appears after a direct search. The user types specific words and the platform displays ads related to that search.

For example, someone searching for “SEO agency Portugal” is showing a clear intention. Companies targeting that keyword can appear through paid ads at the top of the search results.

This model works because there is a direct relationship between search and intent.

With ChatGPT Ads, that intent is interpreted differently.

The user may start a much more complete conversation:

“I have a B2B company and I want to increase my online visibility through digital marketing. What strategies should I implement?”

Or:

“I want to create a professional website for my company. What features should I look for when choosing an agency?”

Artificial Intelligence can understand the context of the question, identify the user’s objective and understand what that person is genuinely trying to achieve.

This is precisely what makes advertising on ChatGPT so relevant.

While Google works mainly with keywords, ChatGPT Ads work with conversational context.

OpenAI presents ChatGPT Ads as a new way to reach users while they explore options, compare alternatives and make decisions within a conversational experience. The company highlights the use of contextual signals to deliver ads that are more relevant and aligned with what users are trying to accomplish. OpenAI

How do ChatGPT Ads work?

ChatGPT Ads were developed with a different logic from traditional digital advertising formats.

Ads appear in connection with relevant conversations and are clearly identified as sponsored content. OpenAI states that ads remain separate from the answers generated by ChatGPT and that advertisers cannot influence the responses provided by Artificial Intelligence. OpenAI Help Center

This separation is one of the most important factors for the adoption of this new model.

The value of ChatGPT lies precisely in the trust users place in the answers they receive. If a brand could pay to directly influence an Artificial Intelligence recommendation, that trust would be compromised.

For this reason, OpenAI’s strategy is to create an experience where advertising appears in the right context, without interfering with the main answer.

ChatGPT Ads support buying models based on CPM, cost per thousand impressions, and CPC, cost per click, bringing the platform closer to the advertising models already used by major digital platforms. OpenAI has also expanded campaign management options through its advertising platform, allowing advertisers to create and manage campaigns more directly. OpenAI

This approach to existing advertising models shows that OpenAI intends to create a real advertising ecosystem, but adapted to a new search reality.

Google Ads remains dominant, but search is evolving

It is important to understand that OpenAI Ads do not mean the end of Google Ads.

Google remains one of the most powerful advertising platforms in the world and maintains a significant advantage in terms of scale, historical data, technological maturity and search volume.

Every day, millions of people continue using Google to find products, services and information.

However, user behaviour is becoming more diverse.

A person may continue using Google when they need a quick and objective answer.

But they may choose Artificial Intelligence when they need to analyse a more complex problem.

This difference creates two distinct moments.

Google is extremely strong when there is already a defined intention.

ChatGPT is becoming increasingly relevant when a need is still being explored.

This initial discovery phase can be extremely valuable for brands because it influences what happens before the final decision.

A company that appears in a conversation where a consumer is comparing solutions can be present during a very important stage of the buying process.

The biggest difference is keywords versus context

Digital advertising has always depended on the ability to understand intent.

But the way intent is interpreted is changing.

With Google Ads, a large part of the strategy revolves around selecting the right keywords.

Companies analyse searches, volumes, competition and cost per click to understand where they should invest.

With ChatGPT Ads, the logic moves closer to understanding an entire conversation.

Artificial Intelligence can interpret a complete question, understand relationships between different concepts and identify the user’s real objective.

This creates a new opportunity for brands that can clearly communicate what they do.

In the future, it will not be enough for a company to simply have a page optimised for a specific keyword.

The information available online will need to demonstrate authority, experience and relevance.

This is where the connection between generative advertising, SEO and GEO, Generative Engine Optimization, becomes essential.

Brands will need to prepare their content not only to appear in traditional search engines, but also to be understood by Artificial Intelligence systems.

OpenAI Ads, SEO and GEO: the new combination of digital marketing

For many years, companies thought about SEO as a strategy to achieve higher positions on Google.

This reality remains important, but a new question is emerging:

How can a brand ensure that it appears when someone asks an Artificial Intelligence system for a recommendation?

This is the foundation of GEO.

Generative Engine Optimization aims to prepare brands and content for a new reality where generative engines do not simply display results, but create answers.

A brand that wants to appear in this new environment needs to demonstrate knowledge, consistency and authority.

It needs deeper content.

It needs clear information.

It needs a coherent digital presence.

OpenAI Ads represent only one part of this transformation.

The other part happens organically, through a company’s ability to be recognised as a reference within a specific topic.

In the future, the combination of SEO, GEO and generative advertising will be one of the most important areas of digital marketing.

The future of digital advertising will be hybrid

The comparison between OpenAI Ads and Google Ads should not be seen as a competition where only one platform will win.

The future will most likely combine both realities.

Google will continue to be essential for direct searches and clearly defined intentions.

ChatGPT and other generative engines will become increasingly important in moments where consumers seek guidance, comparison and recommendations.

Brands will need to understand these different moments in the decision journey.

A person may discover a need through a conversation with Artificial Intelligence, search for additional information on Google, visit a website, compare alternatives and eventually make a purchase.

Future digital advertising will be built through multiple touchpoints.

The major difference is that Artificial Intelligence adds a new layer: the ability to understand context.

OpenAI Ads vs Google Ads: what will be the best choice for businesses?

The answer will always depend on the brand’s objective.

If a company wants to capture people who are already searching for a specific solution, Google Ads will continue to be an extremely powerful tool.

If a company wants to be present while someone is exploring options, comparing possibilities or looking for recommendations, ChatGPT Ads can create a new opportunity.

The biggest change is how brands need to think about advertising.

For years, the objective was to appear when someone searched.

Now it is becoming about appearing when someone decides.

OpenAI Ads represent the beginning of a new phase in digital advertising, where relevance, context and trust will play an increasingly important role.

Companies that start preparing for this change through content, SEO, GEO and Artificial Intelligence strategies will be better positioned to compete in a reality where people are progressively moving from simply searching for answers to asking for recommendations.
