Ask ten agencies what Google Ads costs and you will get ten non-answers, because a straight number makes it harder to sell you a package. So here is the honest version, written for South African service businesses in 2026, with real ranges and the parts most agencies leave off the quote.
The first thing to fix is the question itself. “What does Google Ads cost” bundles together three completely separate charges that behave differently, are paid to different people, and should be judged on different things. Confuse them and you will either overpay or, worse, underspend on the one part that actually decides whether the whole thing works.
Three costs, not one
Every Google Ads arrangement is really three line items:
- Ad spend — the money that goes to Google when someone clicks your ad. This is the fuel, and it should stay in your account, on your card.
- The management fee — what you pay a specialist (or an agency) to build, run and keep improving the account.
- The build — a usually one-off cost for setting the account up properly the first time: campaigns, tracking, landing pages, negative keyword lists.
Keep them separate in your head. The spend is not a fee. The fee is not spend. And a cheap fee attached to badly-run spend is the most expensive option of the lot.
Cost 1: Ad spend — the fuel
This is the money Google charges you per click, and it is the part you have most control over because you set the daily budget. Two things surprise people. First, you are not billed for showing the ad, only for a click. Second — and this is the one to insist on — that spend should run through a Google Ads account in your own name, funded by your own card. If an agency routes your spend through their account, you cannot see what Google actually charged, and some quietly mark it up. More on that later.
Cost per click varies enormously by trade and town, because it is an auction: the more businesses bidding on a keyword, the higher the price. These are the sort of ranges we typically see in South African accounts. Treat them as illustrative, not a quote — your real numbers depend on your location, your competition and how well your account is built.
| Trade | Typical cost per click | Notes |
|---|---|---|
| Cleaning | R6 – R20 | Lower competition, high volume |
| Roofing / waterproofing | R10 – R30 | Spikes in storm season |
| Plumbing / electrical | R12 – R35 | Emergency intent, pricier in metros |
| HVAC / aircon | R10 – R28 | Seasonal in most of the country |
| Construction / renovation | R10 – R30 | Long sales cycle, high job value |
| Solar / security | R15 – R45 | Demand-driven, climbing |
| Attorneys / legal | R35 – R90+ | The most expensive category in SA |
But cost per click is the wrong number to obsess over. What you actually buy is a lead, and then a job. A R12 click that never converts is more expensive than a R40 click that books a R20,000 job. Judge the account on cost per lead and cost per job, not the click price.
Say you are a Durban plumber spending R10,000 a month. At an average R20 click, that is roughly 500 clicks. A solid landing page and a working call setup might convert 6–10% of those into real enquiries — call it 40 leads. Close a quarter of them and that is 10 jobs. If your average job is R2,500, that is R25,000 in work off R10,000 of spend plus the fee.
Now weaken one input — a worse landing page, a pricier keyword, a slower phone — and the whole chain moves. That sensitivity is exactly why the click price alone tells you almost nothing.
How much spend do you actually need?
There is a floor and a ceiling, and both matter.
The floor is set by Google's learning system. It needs a steady flow of clicks and conversions to work out who to show your ads to, and starve it and it never calibrates. In most South African trades that means roughly R150 to R300 a day as a practical minimum. Spend R1,500 for a whole month and you will get a trickle of poorly-optimised data and conclude, wrongly, that “Google Ads doesn't work.”
The ceiling is set by you, and most people get this backwards. Work from the number of jobs you can actually service, not from a budget you can afford to burn:
Want 15 new jobs a month? If you close one lead in four, you need about 60 leads. At an 8% click-to-lead rate, that is roughly 750 clicks. At R20 a click, about R15,000 in spend.
Then sanity-check the top of that chain: can you actually do 15 extra jobs this month? If not, spend less. Generating leads you cannot answer just burns money and your reputation.
Cost 2: The management fee
This is what you pay for the account to be built well and improved every week — the negative keywords added, the budget shifted to what is converting, the bids tuned, the wasted searches cut. There are three common models in South Africa, and they are not equal.
Percentage of ad spend (often 10–20%)
Simple and scalable, but it contains a quiet conflict: the agency earns more when you spend more. Its incentive is to grow your budget, not to make a smaller budget work harder. That is fine when interests align and dangerous when they don't.
Flat monthly retainer
A fixed fee regardless of spend. For small and mid-sized service businesses this typically runs from around R2,500 to R8,000+ a month depending on scope. The advantage is clean incentives — the specialist earns the same whether you spend R8,000 or R80,000, so the job becomes efficiency, not upselling. This is the model we use at LeadSurge, from R4,500 a month, precisely so our cut never grows just because your budget does.
Per-lead or “performance” pricing
Attractive on the surface, awkward underneath. Lead quality is hard to police, the definition of a “lead” gets fuzzy, and once volume is decent you often overpay per lead compared with a flat fee. Treat guarantees attached to these deals with real suspicion.
Cost 3: The one-off build
Doing it properly the first time is real work: keyword and competitor research, campaign structure, conversion tracking, a landing page that actually converts, and the negative keyword lists that stop you paying for the wrong searches on day one. Most specialists charge a one-off build fee to cover it, after which you are on the monthly fee alone. It is money well spent — an account launched without this groundwork wastes budget for months before anyone notices.
The costs nobody quotes you
This is where the honest and the not-so-honest part ways.
- The landing page and tracking. Pointing ads at a slow homepage with no clear next step is the single most common way to waste a budget. Conversion tracking is non-negotiable — without it you are flying blind.
- Call tracking. For most trades the lead is a phone call, so you need to know which calls came from ads. Otherwise you cannot tell what is working.
- The learning period. The first few weeks are calibration, not performance. Budget for two to three months before you judge results, and be wary of anyone who doesn't warn you about this.
- Spend markup. Some agencies buy your clicks through their own account and add a margin you never see. Insist your spend runs through your account on your card.
- Account ownership. If the agency owns the Google Ads account, you lose every bit of history, data and audience the day you leave. That is a switching cost dressed up as a convenience. The account must be in your name.
- Lock-in contracts or long notice periods
- The agency owns your Google Ads account
- Your spend is routed through the agency's account
- Guaranteed results or a guaranteed “number one on Google”
- No direct access to your own account or reporting
- A percentage fee that rises with spend and no efficiency incentive
What to realistically expect in the first three months
Month one is the build and the learning phase: data comes in, the system calibrates, and the numbers are noisy. Month two is refinement — negatives added, bids adjusted, the landing page tightened — and your cost per lead should start trending down. Month three is the first fair read on whether the channel works for your business at your budget. Anyone selling you a return in week one has told you everything you need to know about them.
So, what does it actually cost?
For a typical small South African service business, a realistic all-in starting point is somewhere around R10,000–R15,000 a month of ad spend, a flat management fee from about R4,500, and a one-off build in month one. Trade, town and competition move those numbers, and the only way to know your real figures — your actual cost per click, per lead and per job — is to look at real data for your market.
