Is Google Ads worth it? An honest answer for UK small businesses

The short answer: it depends on three things, and you can test all of them

Google Ads Search shows your ad to someone at the moment they type what they want into Google, and charges you when they click. There's no monthly fee to Google and your daily budget is a hard cap. So "is Google Ads worth it" really means "is a click in my market worth more to me than it costs", and that has a different answer for a roofer in Bedford than for a solicitor in Manchester.

We run Google Ads accounts for UK lead-generation businesses, so we've an obvious interest in the answer being yes. That's why the rest of this page is built on tests you can run yourself, using click prices we publish, and why the list of situations where it isn't worth it is as long as it is.

intent · economics · response · fail one and the other two won't save it

Test 1: do people search for what you sell with buying intent?

Google Ads only works when someone is already looking. If your customers don't type your service into Google, no budget or clever bidding will conjure them. And "searching for it" isn't enough on its own: the search has to be one a buyer makes. "Emergency plumber near me" is a buyer. "How to fix a dripping tap" is someone about to watch a YouTube video.

How to check in ten minutes

1. Write down five to ten phrases a customer would type when they need you today, with the place name if you serve a local area.
2. Search each one on your phone. Are there ads at the top from businesses like yours? Are the organic results companies selling the service, or articles explaining it? A page of guides and forum threads means Google reads that search as informational, and your ad would be answering a question nobody asked.
3. Open Keyword Planner. It's free inside any Google Ads account and you don't have to spend anything to use it. Put your phrases in and read two columns: monthly searches for your area, and the bid range. That range is your first honest look at what a click will cost.
4. Sort the list into buying phrases (quote, cost, near me, emergency, a service plus a town) and learning phrases (how, why, DIY). If the buying phrases have real volume in your area, you pass. If only the learning phrases do, you don't, and that's worth knowing now.

For the sectors we track, the live search demand and click prices sit in two calculators: one for trades and one for professional services. Pick your niche, set a budget, and it shows the clicks and enquiries that budget could reasonably buy.

Test 2: do your unit economics survive the real UK click cost?

This is the test most "is it worth it" articles skip, because it needs numbers rather than opinions. A click costs what the auction in your market says it costs, and that varies by more than ten times between niches. Here's a spread of average UK click prices from the live Google Ads dataset behind our calculators and our cost per lead guide.

Source: UK Google Ads data (DataForSEO), July 2026, average cost per click on the core commercial search terms we track in each niche. Click counts are simple division, before any optimisation either way.

The click price alone doesn't tell you whether it's worth it. Cost per enquiry is the click price divided by the rate at which your landing page turns clicks into enquiries. On a dedicated landing page taking paid search clicks, our landing page conversion rate guide treats 12% as strong and uses 10% as the illustrative figure; a homepage usually does far worse, which is why sending ads to your homepage is the fastest way to make Google Ads look like it doesn't work.

Then work out what you can afford to pay for an enquiry: your average job value, times the share of it you'd give up to win one, times the share of enquiries you actually turn into customers. If the cost per enquiry the click maths produces sits under that ceiling, Google Ads can be worth it. If it sits over, the fix is the page or the offer, not a bigger budget. The full method is in how to set a Google Ads budget for lead generation.

A worked example, with the maths shown

Take a roofer spending £1,000 a month. The click price is the live UK figure from the table above; the 10% landing-page rate and the 30% close rate are illustrative inputs to swap for your own. The model stops at enquiries, because that's where the ad account's job ends and yours starts.

Roughly £42 an enquiry against a £54 ceiling: on those inputs the roofer's account has room, and Google Ads is worth testing. Now run the same £1,000 for a solicitor at £8.93 a click. That buys about 112 clicks, which at the same 10% is around 11 enquiries at roughly £91 each. Whether that's worth it depends on what a case is worth to the firm and how many enquiries become instructions. Same channel, same budget, and the answer can go either way.

What real accounts have produced

The example above is arithmetic. Our case studies publish what actual accounts did, with the spend and the window shown. A DPF-cleaning specialist on £10,000 a month went from £86.50 a lead to £19.97 account-wide in 30 days, with the average click falling from £3.50 to £1.60. A steel fabricator with no website and one customer got B2B enquiries at about £42 each on £1,700 a month. A brand-new cosmetic surgery clinic on £4,000 a month reached around 70 enquiries a month at about £53 each inside 90 days. Each is one account, in one sector, over one window, and each page says what it doesn't prove. They show the channel can be worth it when the three tests pass; they don't tell you what your account will do.

Test 3: can you answer enquiries fast enough?

This one gets left out because it isn't a Google Ads problem, but it decides whether the money was worth spending. A search enquiry is someone who needs the thing now and has probably opened three tabs. If your phone rings out at 2pm on a Tuesday, or a form sits unanswered until Thursday, that enquiry has already booked someone else and your £42 is gone.

Before you spend, answer these honestly. Who picks up when you're on a roof, in court or with a patient? What happens to a form submitted at 7pm? Can you quote within a day? Do you know how many of last month's enquiries you actually called back? None of these needs a marketing budget to fix, and fixing them raises the value of every enquiry you buy. If the honest answer is "nobody, nothing, no and no", Google Ads isn't worth it yet, and the fix is a phone rota, not a campaign.

the account's job ends at the enquiry · yours starts there

When Google Ads isn't worth it

We'd rather say this here than after an audit, because an audit that finds one of these says the same thing in writing. Google Ads is a poor fit when:

• The job value can't cover the click price. If you sell £40 jobs and clicks in your market cost £5, you'd need an unrealistic enquiry rate and close rate just to break even. Fix the offer or the average order first.
• Nobody searches for it with intent to buy. New categories, products people don't know exist, and services bought on recommendation don't show up in a search box, and no budget fixes that.
• There's no page worth sending a click to. A slow homepage with no phone number above the fold wastes most of what you spend. Build the landing page first.
• The budget is too small to learn anything. Around £500 a month is where we tell most service businesses to think hard; in a market with £5 clicks it buys one or two a day and never leaves guesswork. Waiting and saving is a legitimate plan.
• You need the work this week. Ads are approved within about a business day, but leads arrive over weeks as data builds, and a fair verdict needs about three months. See how long Google Ads takes to work.
• Your work is won by tender or framework, not enquiry. Google Ads won't win the multi-million contract, and we say so. It can bring in the smaller jobs around it, which is a different brief.
• You can't take on more work. Enquiries you can't fulfil are money spent to annoy people. If the diary is full for four months, spend on capacity.
• You can't answer the phone. Test 3 again, because it quietly ruins accounts that pass the other two.

None of these is permanent. Most are things to fix, and once fixed the answer flips. But they're the honest reasons a campaign that "didn't work" was usually never going to.

How to test it for 30 days without an agency

If the three tests pass on paper, the cheapest way to find out for real is a small, tight campaign you run yourself. You'll learn your actual click price and enquiry rate, the two numbers everything else depends on.

1. 1

   Fix tracking before spending

   Set up conversion tracking for calls and forms and test it fires. Most "Google Ads doesn't work" verdicts come from accounts that never measured anything.

   before day 1

2. 2

   One service, one page

   Pick your most profitable service and send clicks to a page about that service only, phone number and short form at the top. Not the homepage.

   before day 1

3. 3

   Tight keywords, tight area

   Ten to twenty buying phrases on exact and phrase match, a radius you'd actually drive to, and negatives for DIY, jobs, free and course.

   day 1

4. 4

   Set a budget that buys data

   Around £20 a day works where clicks cost £1 to £3; in a £5-plus market you'll need more or you'll learn nothing. Use the calculator to size it.

   day 1

5. 5

   Check search terms weekly

   Open the search terms report weekly and add negatives for anything you'd never pay for. Leave bids and structure alone; big changes reset the learning.

   weeks 1–4

6. 6

   Judge on cost per enquiry

   At day 30, divide spend by enquiries and compare it to your allowable figure. Ignore clicks and impressions; they aren't what you're buying.

   day 30

Be fair to the test. Thirty days is enough to learn your click price and get a first read on your enquiry rate; it isn't enough for a final verdict, which needs about three months. If at day 30 the cost per enquiry is in the right region and the enquiries are the kind of work you want, keep going and tighten. If clicks are piling up with no enquiries at all, run the clicks but no conversions diagnostic before you blame the channel, because it's usually tracking or the page.

If you'd rather have someone check the setup, our free PPC audit reviews the account against a published 10-point checklist and puts the findings in writing, with no obligation. If the economics can't work, it says so, and that's a cheaper answer than 30 days of spend. Ongoing management is priced on the pricing page, from £750 a month, so you can weigh the fee against the test result rather than guess.
