Google Ads is the fastest way to buy demand and the fastest way to waste money, and the difference between those outcomes is mostly structural. Accounts that perform are rarely run by cleverer people than accounts that do not. They are set up so that the right signals reach the bidding system and the wrong searches never get a chance to spend.
This guide explains how Google Ads works, what it costs in South Africa, which campaign types suit which goals, how to measure properly, and where budgets most often leak.
How does Google Ads work?
Google Ads runs an auction every time someone searches. Your position is decided by Ad Rank, which combines your bid with the quality of your ad: expected click-through rate, how relevant the ad is to the search, and the experience on the page it leads to. That is why the highest bidder does not automatically win, and why a competitor bidding less can appear above you.
You also rarely pay your full bid. The actual cost per click is generally what is needed to hold your position against the next advertiser, so better ads and landing pages lower the price of every click as well as improving its position.
How much does Google Ads cost in South Africa?
There are two costs: the media you pay Google for clicks, and the management of the account. Google has no minimum spend, and cost per click varies widely by industry, location and competition. Legal, finance, insurance and some B2B services usually cost far more per click than retail or local consumer services, and Johannesburg is typically more expensive than smaller markets for the same keyword.
Management in South Africa is usually charged as a monthly retainer or a percentage of ad spend. Lulonke’s published rates are:
| Management plan | Fee | For accounts spending | What it includes |
|---|---|---|---|
| Growth Acquisition Engine | R9,500 – R18,000 a month | R25,000 – R100,000 a month on ads | Campaign structure and negative keyword management, server-side conversion tracking, ad testing and weekly copy iteration, landing page audit, a live results dashboard |
| Scale Portfolio Management | 10% – 15% of ad spend | R100,000+ a month on ads | Multi-channel management across Search, Performance Max, Meta and LinkedIn, weekly creative refreshes, attribution synced with your CRM, daily bid and budget management, a senior strategist |
Both plans run month to month after a three-month initial period, which is roughly how long a properly measured account needs to show what it can do. See paid media for the full scope.
How much should you spend on Google Ads?
Spend enough to generate a steady flow of conversions, then scale what works. Automated bidding strategies learn from conversion data, and they make poor decisions on a trickle of it: Google has historically recommended around 30 conversions a month for target cost-per-acquisition bidding, and more data always helps. If your budget cannot buy that many, narrow the campaign to your most valuable service and area rather than spreading thin.
Budgets are set per day. On any single day Google may spend up to twice your daily budget when there is demand, but over a month it will not charge more than your daily budget multiplied by the average number of days in a month.
Which Google Ads campaign types should you use?
| Campaign type | Use it for | Watch for |
|---|---|---|
| Search | Capturing people already searching for what you sell | Broad match spending on loosely related searches |
| Performance Max | Automated reach across Search, YouTube, Display, Gmail and Maps | Limited visibility into where spend goes; needs strong conversion data |
| Shopping | Showing products with price and image in results | Product feed quality decides everything |
| Display | Reach and remarketing to past visitors | Placement quality; exclusions matter |
| YouTube and Demand Gen | Creating demand before people search | Harder to measure; judge on assisted results, not last click |
For most businesses starting out, Search is where the money should go first. It captures people who have already told Google what they want, which is the cheapest demand there is. Add other types once Search is measured and profitable.
How should you measure Google Ads results?
Measure what the business values, not what is easy to count. Optimising against inaccurate conversion data is not neutral: it makes results worse, because automated bidding will confidently move budget toward the wrong signal.
- Confirm each conversion fires once, on the right action, and is not double-counted.
- Separate real leads from low-value actions such as newsletter sign-ups and supplier enquiries.
- Give conversions values so bidding can tell a quote request from a brochure download.
- Feed offline outcomes back into Google Ads where possible, so it learns which clicks became customers.
- Track calls and WhatsApp enquiries, which are a large share of leads for many South African businesses.
Where do Google Ads budgets leak?
- Broad match keywords without a negative keyword list that is actively maintained.
- Bidding on your own brand name when you already rank first and no competitor bids on it.
- Sending every ad to the homepage instead of the page that matches the search.
- Showing ads to people outside the areas you serve, often because location targeting includes people merely interested in an area.
- Running ads when nobody can answer the phone or reply on WhatsApp.
- Ignoring the search terms report, where the real searches that triggered your ads are listed.
Why does the landing page matter so much?
A large share of poor Google Ads performance is not a Google Ads problem. If the page loads slowly on mobile, does not match the promise in the ad, or hides the action, no bid strategy fixes it. Landing page experience is also part of Ad Rank, so a better page lowers what you pay per click. Our guides to website speed and conversion optimisation cover the fixes.
Should you manage Google Ads yourself or hire someone?
A small account with a handful of keywords in one area can be run in-house by someone who has time to review search terms weekly. As spend grows, or once you add Performance Max, Shopping or several regions, the cost of mistakes usually exceeds the cost of management. Whoever runs it, insist that the account is owned by your business, so the data stays with you if you change providers.
Frequently asked questions
How much does Google Ads cost per month in South Africa?
There is no minimum spend; you set a daily budget. Many South African businesses spend from a few thousand rand a month for a single local campaign to R100,000 or more for national campaigns. Management usually costs extra: Lulonke charges R9,500–R18,000 a month for accounts spending R25,000–R100,000, or 10–15% of spend above that.
How much does a click cost on Google Ads?
It varies by industry, location and competition. Highly competitive sectors such as legal, finance and insurance cost far more per click than local retail. Better ads and landing pages lower the cost, because Ad Rank rewards quality as well as bid.
How long before Google Ads gets results?
Ads can bring traffic on the first day, but a properly measured account usually needs a few weeks of data for automated bidding to settle and around three months to show its real performance.
What is a good conversion rate for Google Ads?
It depends on the industry and what counts as a conversion. Compare your cost per qualified lead and cost per customer over time rather than a generic benchmark, and make sure only real leads are counted.
Should I use Performance Max?
Performance Max can work well once you have reliable conversion tracking and a healthy volume of conversions. For most businesses starting out, a well-structured Search campaign is the better first step, because you can see exactly which searches you pay for.
Who should own my Google Ads account?
Your business should. The agency or freelancer should be given access to your account, not run your ads inside theirs. Otherwise you lose years of performance data if you change providers. See our guide to choosing a digital marketing partner.
