Google Ads is the fastest way for a South African small business to buy demand that already exists. It is also the fastest way to waste a budget. The difference comes down to a handful of setup decisions made before the campaign ever goes live.
Start with intent, not volume
Broad, high-volume keywords are expensive and rarely convert for small businesses. The money is in specific, high-intent searches — ’emergency plumber Centurion’ beats ‘plumbing’ every time, at a fraction of the cost per click.
Build your first campaigns from the exact phrases customers use when phoning you. Those phrases are already in your inbox and your call log.
Geography and scheduling do the heavy lifting
Restrict targeting to the radius you actually serve. If you will not drive to Pretoria, do not pay for clicks from Pretoria. Then check when your enquiries convert — if nobody answers the phone after five, schedule ads to stop at five.
Negative keywords are not optional
Every account we audit is haemorrhaging budget on irrelevant searches. Add negatives before launch and review the search terms report weekly for the first month.
- ‘free’, ‘cheap’, ‘DIY’, ‘jobs’, ‘salary’, ‘course’
- Competitor brand names, unless you are deliberately bidding on them
- Products and services you do not offer
Send clicks to a matching page
The most expensive mistake is paying for a click on a specific service and dropping the visitor on a homepage. The landing page must repeat the search phrase, prove you deliver it, and offer one way to make contact.
Measure the thing that pays you
Track calls and form submissions as conversions, not clicks or impressions. Then work backwards: if a customer is worth R8 000 and one in four enquiries closes, you can comfortably pay well over R500 for an enquiry. Without that number, you are guessing.
Tight targeting, aggressive negatives, matching landing pages, and conversion tracking on the things that generate revenue. Everything else is optimisation.
