Ads appear below answers for logged in users on the Free and Go plans, clearly labelled. Paid plans do not see them. There is no minimum spend for self-serve campaigns.

Is a test right for you?

A test makes sense when buyers research before they contact you and the deal is worth enough to justify a learning budget. That covers most B2B services, industrial suppliers, private clinics and professional firms.

Two cautions. Local targeting is still young, so a business that serves one town may waste spend. And policy for healthcare and finance is still developing, so clinics should check the current ad policy for their treatments before launch and keep claims factual.

Week 1: foundations

• Write your fact sheet and make your site, Google Business Profile and LinkedIn match it.
• Pick two or three buyer questions with clear commercial intent.
• Build or adapt one landing page per question. Answer first, proof second, action third.
• Install the pixel or Conversions API and send the same lead event you use for Google Ads.
• Allow the OAI-AdsBot crawler on landing pages.

Week 2: launch small

Create one campaign with an ad group per question. Write three creative variants each: a title of about 16 characters, a line of about 32, a real image. Start on click bidding so you only pay for visits; reported starting bids are around $3 to $5 per click, and very low bids often fail to deliver.

Set a daily budget you are comfortable losing while you learn. The aim of week two is data, not profit.

Week 3: optimise

• Pause variants with low click-through after a few hundred impressions.
• Read the search terms in your CRM notes and sales calls: what were people actually asking?
• Tighten the landing page where people drop off.
• If you have enough conversions, test conversion optimised bidding.

Week 4: judge on leads

Look at

• Booked calls or qualified enquiries
• Cost per qualified lead
• Lead quality from sales
• Assisted conversions in GA4

Do not judge on

• Click-through rate alone
• Impressions
• Cost per click
• One good or bad week

Put ChatGPT and Google Ads side by side on cost per qualified lead. If ChatGPT is within reach after one month, it usually improves as context and creative mature. If it is far off, fix the fact base and landing pages before spending more.

Frequently asked questions

Are ChatGPT ads available to UK businesses?

Yes. Ads went live in the UK on 6 June 2026, and self-serve buying opened to UK advertisers in June and July 2026.

Is there a minimum spend?

No minimum applies to self-serve campaigns. Plan a learning budget that lets each ad group collect meaningful data over a month.

Should I pay per click or per thousand impressions?

For lead generation start with cost per click, so you pay for visits. Impression buying suits awareness goals.

Can clinics advertise on ChatGPT?

Check the current policy for your treatment category before launch. Policy for healthcare is still developing, so keep claims factual and avoid outcome promises.

How long should a test run?

At least 30 days. Judge it on booked calls and cost per qualified lead against your other channels.
