In short
How buyers use ChatGPT to shortlist a Google Ads agency, where its answers come from and the five questions to ask any agency before you sign.
Businesses use ChatGPT to build a shortlist of Google Ads agencies, compare how agencies charge and check what each one says about itself before they pick up the phone. When ChatGPT searches the web for those answers, the agencies it names are the ones whose facts are clear, consistent and easy to find. Treat its answer as a starting shortlist, then test every agency with the questions below.
How are businesses using ChatGPT to find a Google Ads agency?
AI tools are now part of how people research. Ofcom's 2026 research on UK adults' media lives found that more than half (54%) of UK adults now use AI tools such as ChatGPT, Copilot or Gemini. When you need someone to run your paid search, ChatGPT gives you a quick overview before you start reading agency websites one by one.
The most useful questions to put to ChatGPT are specific. "Which agencies manage Google Ads for small businesses in the UK?" "What should a Google Ads agency charge a month for a £2,000 budget?" "Should I pay a flat fee or a percentage of ad spend?" "Do I keep my Google Ads account if I leave an agency?" An agency's best work sits inside ad accounts you can't see from outside, so it pays to understand how agencies charge and work before you compare names.
Where does ChatGPT get its answers about agencies?
OpenAI's ChatGPT search help page, checked in November 2026, says "ChatGPT will automatically search the web if your question might benefit from information on the web", and that responses using search contain inline citations. You can click a citation to see the source and find every cited source through the Sources button at the end of the answer.
That tells you what an AI shortlist is made of: whatever public pages the search turns up, such as agency websites, review profiles, directories and articles. Google's AI search features also pull from several searches at once. Google's AI features guidance, updated in December 2025, says AI Overviews and AI Mode can use a "query fan-out" technique, issuing multiple related searches across subtopics and data sources to build a response.
None of these tools log in to an agency's client accounts. They can't see cost per lead, wasted spend or how often anyone checks search terms. An agency that gets named has published clear facts that other sources back up. That's useful, but it isn't proof of results.
How do you get a useful answer from ChatGPT?
Give it the details an agency would ask for. Tell it your sector, the area you serve, your monthly ad budget, whether you want calls, forms or sales, and whether you need Meta Ads alongside Google. Ask it to cite its sources, then open them. If an agency is named but the citation is a two-year-old directory listing, that's a weak signal.
Ask ChatGPT to explain pricing models side by side rather than to rank agencies. It's good at setting out the difference between a flat management fee, a percentage of spend and a minimum term. Our guide to what Google Ads costs a small business in the UK gives you the figures to check its answer against. If you're weighing up a freelancer instead, read Google Ads agency or freelancer before you decide.
What should you ask a Google Ads agency before you sign?
Once you have a shortlist, the conversation with each agency matters more than anything an AI tool said. These five questions separate the agencies that manage accounts closely from the ones that set them up and leave them.
- Who owns the Google Ads account and the data if you leave?
- What's the monthly management fee, what's the minimum term and do you pay ad spend directly to Google?
- How often do they check search terms and block wasted searches?
- How long until campaigns go live, and what happens in the first month?
- Can they show a case study with leads and sales, not just clicks?
Here's how we answer them for Google Ads management at DLR Media. Plans are Starter £600, Growth £1,000 or Scale £1,800 a month + VAT, on a 6-month minimum, and you pay ad spend directly to Google. You get a free audit first, campaigns go live in 5 days on average and we check search terms every weekday. For Caltech Lifts, a stairlift company, our Google Ads work produced 35 qualified leads, 15 completed sales and a sales pipeline of up to £120,000.
Put the same questions to every agency on your list. Clear, specific answers are what you want. Vague promises about "maximising ROI" without a term, a fee or a case study are a reason to move on.
Should you trust an agency ChatGPT recommends?
Trust it as far as its sources go. A name in a ChatGPT answer means the tool found that agency, could read its pages and saw facts repeated elsewhere. It doesn't mean the agency is the best fit for your budget or sector. Open the citations, compare what each agency publishes about price, term and account ownership, and judge the case studies yourself.
The same process decides whether your own business gets named when customers ask AI tools for a supplier in your sector. That work is called generative engine optimisation, and we explain how it works on our GEO page.
Frequently asked questions
Can ChatGPT tell me which Google Ads agency is best?
No. ChatGPT can summarise what agencies publish and what other sites say about them, but it can't see inside anyone's ad account. Use it to build a shortlist and understand pricing, then judge each agency on its answers, terms and case studies.
Does ChatGPT show where its agency suggestions come from?
Yes, when it searches the web. OpenAI says responses that use search contain inline citations, and the Sources button lists every cited source. Open them to check how current and credible they are.
How much should a Google Ads agency charge a small business?
It depends on your ad budget, how many campaigns and locations you run and whether you need other platforms such as Meta Ads. Our management plans start at £600 a month + VAT, with ad spend paid directly to Google.
Is it better to use an agency or a freelancer for Google Ads?
It depends on your budget, how much day-to-day checking your account needs and whether you want one person or a team. Ask both the same five questions above and compare the answers on fee, term, account ownership and results.
