Paid search intelligence
OpenAI can automatically rewrite your ChatGPT ad headlines, images and landing URLs without an approval step — and advertisers may have only days to opt out. Here is what UK businesses need to check right now.
What has been reported
OpenAI says ChatGPT Ads has expanded to 26 new countries, with over 100,000 advertisers having used the platform. The pitch is simple: reach people while they explore, compare and decide what to buy inside ChatGPT.
A separate report from PPC Land says OpenAI will rewrite self-serve ChatGPT ads by default. According to PPC Land, headlines, images, landing URLs and language may all change, and there is no approval step for each new version. Advertisers reportedly have only days to opt out.
That rewrite detail comes from PPC Land's reporting. It does not appear in OpenAI's expansion announcement, so check the current terms in your own account before acting on it. Which markets offer self-serve ChatGPT ads also changes over time. If the UK is not yet one of them, this still matters for UK firms advertising in countries where the ads are live.
The open question PPC Land raises is the useful one: will advertisers see which version of an ad actually ran? Without that, it is hard to judge results, and harder to answer a customer who quotes something you never wrote.
The unpaid answers matter too
The paid slot is only half of what people see in ChatGPT. The ordinary answers cite websites of their own, and those sources can differ from the ones you are used to seeing at the top of Google. Sayu's study found that most sites AI assistants cite for UK searches sit outside Google's top 10.
Some sites also shut OpenAI's crawlers out. In October 2026, 9.1% of the 4,377 most-visited UK (.uk) websites checked blocked GPTBot, OpenAI's crawler for training AI models. That was the most-blocked of the 11 AI crawlers checked. Separately, 5.4% blocked ChatGPT's user-triggered fetcher, which collects a page when someone asks ChatGPT about it. These figures come from a single snapshot of robots.txt files. They count only blocks covering the whole site, so they miss partial blocks and other ways of restricting access.
The practical point: if your site blocks ChatGPT's fetcher, the unpaid answers may struggle to read your pages, however much you spend on the paid slot.
What this means for UK businesses
Decide on automatic rewriting yourself instead of leaving it on by accident. Lock down the things a rewrite could put at risk: prices, offers, regulated claims and landing pages. Ask for reporting on which ad versions served, and match it against your results. Then check that your own site lets ChatGPT read the pages you want it to cite.
