OpenAI has officially launched the ChatGPT Ads Expansion UK, bringing their advertising platform to the United Kingdom and five other major markets. Alongside this expansion, they are testing a new ad unit that groups multiple advertisers together in a single placement. For UK businesses, this represents a significant new channel opening up, and the time to test it is now, before the competition increases.
This guide breaks down what is changing, why it matters, and whether these ads are worth your marketing budget.
What is happening with ChatGPT ads right now
OpenAI is making three significant moves simultaneously.
Geographic Targeting Expansion
First, they are expanding geographic targeting beyond the US, Canada, Australia, and New Zealand. The UK is now included, along with Japan, South Korea, Brazil, and Mexico. This is the biggest news for UK businesses because it means you can finally advertise directly to ChatGPT users in your own market.
Multi Advertiser Placements
Second, they are testing multi advertiser placements. Instead of showing a single sponsored result, ChatGPT will now group multiple relevant ads together in one placement. This is sold through a second price auction model, the same pricing mechanism used across Google and Facebook.
New Campaign Management Features
Third, they are rolling out new campaign management features that make the platform easier to use and more competitive with mature advertising ecosystems like Google Ads.
For UK businesses, the expansion alone is worth paying attention to. The multi advertiser test could reshape how advertising appears within AI conversations if it succeeds.
The Multi Advertiser Placement Test Explained
This is the biggest change and worth understanding clearly.
Currently, when you see an ad in ChatGPT, it is a single sponsored result. Under the new test, multiple relevant ads will appear grouped together in the same placement, similar to how Google shows ads side by side.
Each ad is sold through a second price auction, which means you bid on a placement and pay the second highest bid price if you win. This is familiar to anyone running Google or Meta ads, so the mechanics are not new.
Why OpenAI Is Testing This Format
Why is OpenAI doing this? Two reasons.
First, it creates more ad inventory without cluttering the user experience.
Second, it gives advertisers more opportunities to reach users during high intent moments, like when someone is asking ChatGPT for solutions to a real business problem.
For advertisers, the multi advertiser format means more competition for placements but also more visibility if your ad is relevant enough to be selected alongside others.
New Features Coming to ChatGPT Ads Manager
OpenAI announced several updates designed to reduce campaign management friction.
Budget Management Improvements
You can now convert existing campaigns from lifetime budgets to daily budgets with a single click. Daily budgets will move to an average daily budget model with weekly pacing flexibility, giving you more control over spend consistency throughout the week.
Campaign cloning is faster too. You can clone a CPM campaign and convert it to CPC bidding in one action, which saves time when testing different bidding strategies.
Bidding and Targeting Updates
Impression based campaigns now support custom CPM maximum bids, giving you more granular control over what you are willing to pay per thousand impressions.
Geographic targeting has expanded significantly. The platform now supports the UK, Japan, South Korea, Brazil, and Mexico alongside existing markets. This is crucial for UK businesses because you can now target users in your own country instead of relying on broader regional targeting.
Bulk Editing and Management
Bulk editing is now available directly within Ads Manager. You no longer need to edit campaigns one at a time. This reduces friction and makes managing multiple campaigns far more practical.
Why ChatGPT Ads Matter for UK Businesses
ChatGPT has tens of millions of active users globally, and that number is growing. Users access it for research, problem solving, learning, and decision making. These are high intent moments.
When someone is asking ChatGPT “what is the best accounting software for small business” or “how do I improve my website conversion rate”, they are actively looking for a solution. That is fundamentally different from scrolling Instagram where ads interrupt the feed.
ChatGPT ads appear within real conversations. They are contextual. They show up when intent is present. That makes them powerful for the right businesses.
The UK expansion means you can now reach these users without geographic compromises. You are targeting people in your own market, in your own language, at the moment they are actively seeking solutions.
ChatGPT Ads vs Google Ads: What Is the Difference
Both are intent based. Both reach people actively looking for something. But they work differently.
Google Ads
Google Ads are keyword triggered. Someone types a search and your ad appears because it matches that keyword. The user is in search mode. They are comparing options openly.
ChatGPT Ads
ChatGPT Ads appear within a conversation. Someone is asking ChatGPT for advice or solutions. Your ad shows up as a relevant option within that answer. The user is in discovery mode, not comparison mode.
The Buyer Journey Difference
Google is where people go when they know they need something. ChatGPT is where people go when they are figuring out what they need.
Both are valuable. They reach different moments in the buyer journey. Many businesses will benefit from testing both.
Should Your Business Advertise on ChatGPT
Good Fit for ChatGPT Ads
B2B services, consultancies, SaaS products, educational services, and business tools tend to perform well on ChatGPT because users are actively seeking solutions and willing to research options. If you sell a service or solution to businesses, this channel is worth testing now.
Worth Testing but Consider Carefully
Ecommerce can work depending on the product. Local services depend on industry and how people search for them. Consumer brands are still in early days on the platform, so results are unpredictable.
How to Get Started with ChatGPT Ads
The process is straightforward.
- Create or log into an OpenAI account.
- Access Ads Manager Beta.
- Set up a campaign with a test budget, ideally between £500 and £2,000 to gather meaningful data.
- Use the new UK geographic targeting to reach your actual market.
- Monitor performance closely because this is still an emerging channel and user behaviour is still shaping up.
Start with a single campaign, a single offer, and a clear conversion goal. Do not try to test everything at once.
What to Watch as ChatGPT Ads Grow
Multi Advertiser Placements
The multi advertiser placement test will be the biggest indicator of how aggressively OpenAI plans to monetise ChatGPT. If the test succeeds, grouped placements could become standard, which means more competition and potentially higher costs per placement.
Pricing and Competition
Pricing and competition will likely increase as more businesses discover the channel. Early movers have an advantage before everyone catches on.
Platform Development
More features will roll out over time. Expect better audience segmentation, retargeting options, and creative formats as the platform matures.
The Opportunity for UK Businesses Right Now
ChatGPT ads are still in early days in the UK. Competition is low. User behaviour is still being shaped. Cost per action is likely still reasonable compared to mature platforms.
If your business serves other businesses, solves a clear problem, and can demonstrate results, this channel is worth a test budget right now.

Frequently Asked Questions
The ChatGPT Ads Expansion UK is the official rollout of OpenAI’s advertising platform to the United Kingdom market. It allows local businesses to use the Ads Manager Beta to target UK based users during high intent, conversational moments within the ChatGPT interface.
OpenAI is testing a format where multiple relevant ads are grouped together in a single response rather than showing one sponsored result. This allows users to discover different solutions at once, while giving advertisers more opportunities to reach people during their research and purchase journeys.
This expansion is particularly useful for B2B services, consultancies, SaaS companies, and educational brands. Since people use ChatGPT for problem solving and deep research, the ChatGPT Ads Expansion UK provides a way to appear as the specific answer to a user’s question.
OpenAI uses a second price auction model, which is common in digital advertising. You can bid based on impressions or clicks and choose between daily or lifetime budgets. The ChatGPT Ads Expansion UK also introduces average daily budgets for better weekly pacing.
The platform is currently in a Beta phase. While geographic targeting has expanded to include the UK, businesses need to have an active OpenAI Ads Manager account to access these features and start running campaigns in the newly added markets.
While Google provides a list of links based on keywords, ChatGPT provides a single, conversational response based on context. The ChatGPT Ads Expansion UK allows brands to be part of that cohesive answer rather than just another link on a results page.
We help you determine if this new channel fits your business goals and budget. From technical setup and targeting to creative and tracking, we manage the full process to ensure the ChatGPT Ads Expansion UK delivers actual enquiries rather than just clicks.
