Written by Dan Whalley — I run Quiet Giants, and I have spent a decade inside search. Every number in this article sits in a real client account; where clients have not agreed to be named, the figures stay anonymised. That is the standard I think you should hold any agency to — including this one.
If you are searching for a Google Ads agency for CNC machine shops, you are probably here for one of two reasons: the phone is not ringing from outside your home town, or you are paying an agency already and cannot tell what the money does. This guide covers what good actually looks like for CNC machine shops — and the questions that expose the pretenders in one phone call.
Most agencies are built for e-commerce, dentists and gyms. When CNC machine shops land in that machine, the same things happen every time: a junior who has never set foot on a site writes the pages; the keywords come from a tool instead of the trade; every prospect in the sector gets pitched at once, so the agency quietly works both sides of your local rivalry; and the reporting talks about impressions because it cannot prove enquiries. We built Quiet Giants as the opposite of that — four fronts, one system, one firm per sector, and a tracked number on everything so the report is provable.
Paid search for CNC machine shops is unforgiving of generalists. The searches worth paying for — “cnc machining near me”, “cnc turning [city]”, “precision machining [county]”, “subcontract machining service”, “cnc milling company near me”, “5 axis machining [region]” — need campaigns built around real jobs: radius targeting that mirrors where you would genuinely send a crew, ad copy in the language of the trade, and ruthless negative keywords so you never pay for students, DIY browsers or job-seekers. We wrap campaigns around dedicated landing pages per service (('CNC turning', 'Precision turned parts.'), ('CNC milling', '3, 4 and 5-axis.'), ('Prototype machining', 'One-off and proving.'), ('Production machining', 'Volume runs.'), ('Subcontract machining', 'Capacity on demand.'), ('Inspection and CMM', 'Measured and certified.')) — structured like this — because sending a £-per-click visitor to a generic homepage is how budgets die.
Across our industrial accounts, qualified leads land between £5 and £25. Set that against average order values of £750, £3,500 and £18,000 on those same accounts and the maths explains itself — several of those clients now happily run six-figure annual ad budgets, because every pound is tracked to enquiries, not clicks. That tracking is non-negotiable: a unique phone number and tagged forms on every landing page, so the report says “this call came from this ad, for this service, in this town” — never “trust us, it's working”.
Paid search captures demand this week; the location pages it lands on compound organically for years; and the same structured depth is what ChatGPT and Gemini cite when buyers ask the machines who to use — one of our clients holds roughly 80% of those AI answers in their space. Run as one system, each front makes the others cheaper. Run separately by three suppliers, they fight. That is the whole argument for a single accountable operator — and the honest reason an “AI search agency” pitch on its own should worry you.
From our results ledger: a £2,000,000 contract won from a single Google search in a city the client had never targeted; organic traffic up 250–500% across three accounts once UK-wide coverage was live, with monthly enquiries moving from 4 to roughly 14, 6 to 33, and 10 to 60; and for more than half of our clients, the retainer pays for itself inside the first four weeks. We publish the numbers and withhold the names — our clients do not love their figures broadcast — and any agency you speak to should be able to show you the same class of evidence. If they cannot, that is your answer.
Ask these, in order. One: “Show me a page you built for a trade like mine — who wrote it?” Two: “How many CNC machine shops do you act for in my region?” (The only good answer is one.) Three: “How will I know which town and service each enquiry came from?” Four: “What happens to my rankings if I leave you?” (You should own everything.) Five: “What is your plan for AI search, specifically?” — listen for structure and citations, not buzzwords. Six: “What does the first month actually produce?” Seven: “What would make you tell me to spend less?” An honest operator has an answer; a billing machine changes the subject.
Flat, published, monthly. Ours runs £895, £1,595 or £2,595 a month depending on how far you want to reach, cancellable monthly, with a free growth plan before a penny changes hands. The structure matters more than our number: percentage-of-spend deals reward an agency for spending more, long tie-ins reward it for closing, and “bespoke quotes” usually mean “whatever we think you will pay”. Whoever you choose, insist on flat pricing and a monthly exit — it keeps the agency earning the next month, every month.
We take one CNC machine shop client per region, ever — because you cannot honestly rank two rivals for the same searches. It is also the honest urgency: if a competitor claims your sector first, we cannot act for you. Check availability on the CNC Machining page or browse all 209 sectors. The free plan takes twenty seconds to request: your trade and your patch in, a proper reach map, the search terms you are missing and a 12-month projection back within one working day.
Search is no longer one battlefield, and a serious agency has to fight on four at once. Local search and the Map Pack: the town-by-town pages and the Google Business Profile work that put you on the map — literally — in your home patch and every area you would travel to. Paid search: capturing this week's buyers at a cost per lead the job values can laugh at. Organic content: pages and articles in the genuine language of CNC machine shops, written for a procurement manager as much as for Google, compounding in value every month they exist. And AI search: the structured data and citable depth that make ChatGPT, Gemini and Google's AI answers name your firm when someone asks who to use. Buy them from four suppliers and you get four invoices and no accountability. Built as one system, every front makes the others stronger — the ad landing pages become the ranking pages, the ranking pages become the cited pages, and one tracked number proves the lot.
How long before it works? Paid search and long-tail pages can pull enquiries within weeks; owning a region organically compounds over six to twelve months. For most of our clients the retainer pays for itself well before the compounding even starts. Do I need a new website? Usually not — the machine can be built alongside what you have, and everything we build is yours if you ever leave. Is this just for big firms? No: the sweet spot is £1m–£5m businesses that are brilliant at the work and invisible outside their patch. What about my current agency? Ask them the seven questions above. If the answers are good, stay — genuinely. If they are not, the free growth plan will show you precisely what you are missing, before you commit to anything.
