It's one of the most common questions in digital marketing: should I run Google Ads or Facebook Ads? The short answer is that they serve fundamentally different purposes — and the best answer for most South African businesses is both, but starting with the one that matches where your customers are in the buying journey.
The Core Difference
Google Ads captures existing demand. People search because they already want something. When someone types "plumber Sandton" or "debt counselling Johannesburg" into Google, they have a specific need right now. Your ad appears in the moment of intent. This is why Google Ads tends to drive high-quality, high-intent leads — particularly for service businesses where the customer initiates the search.
Meta (Facebook/Instagram) Ads create demand. You're reaching people who weren't actively searching for you, but who match the profile of your ideal customer. You interrupt their scroll with something compelling. This is more like traditional advertising — you need creative that stops people and a message that makes them realise they have a problem you can solve.
When Google Ads Wins
- High-intent service businesses: legal, medical, financial, home services
- Products or services people actively search for by name
- Emergency services (plumbing, locksmith, roadside assistance)
- B2B services where decision-makers research before buying
- Local service areas where geography is a key filter ("near me" searches)
When Meta Ads Win
- E-commerce and physical product brands
- Lifestyle brands, fashion, food, and wellness
- Businesses targeting specific demographics (new parents, recent graduates, homeowners)
- Building brand awareness and consideration before the search happens
- Retargeting website visitors who didn't convert
- Low-cost products where impulse purchase is realistic

The Smart Approach: Use Both
The most effective strategy for most South African businesses is a combination. Use Google Ads to capture the people actively searching for what you do. Use Meta Ads to build awareness with your ideal audience so that when they eventually search on Google, they already recognise your brand — and they're more likely to click your ad and convert.
If budget is tight and you have to choose one: start with Google Ads if your service is something people actively search for. Start with Meta if your product needs to be seen before anyone thinks to search for it.
The question isn't Google or Meta. It's which one reaches your customer at the right moment in their journey — and the answer is usually both.
