For most SA B2B businesses starting out, Google Ads wins. It captures people who are already looking for your service. Facebook Ads is better for building awareness and retargeting once your foundation is solid. The sequence matters more than the platform.
The Fundamental Difference
Google Ads is demand capture. When someone types "ISO consulting Johannesburg" into Google, they already have a problem and are actively looking for a solution. Your ad meets them at that moment of intent. Conversion rates on high-intent searches are significantly higher than almost any other digital channel.
Facebook Ads is demand generation. Nobody opens Facebook looking for a BEE consultant. They're there to scroll and connect. A well-targeted ad can introduce your business to someone who matches your ideal client profile — but the buying cycle is longer and the intent is lower.
Google Ads catches people who are ready to buy now. Facebook Ads finds people who might buy eventually. Both have a place in a complete system. The question is which one to invest in first.

What the Data Shows in South Africa
Google Ads campaigns for B2B service businesses in South Africa consistently deliver cost per qualified lead of R23–R150 for well-structured campaigns on high-intent keywords. The key word is qualified — people actively searching for the exact service being advertised.
Facebook campaigns for the same businesses generate higher lead volume at lower cost per click — but lead quality is more variable. The conversion rate from Facebook lead to qualified prospect is lower, so the true cost per qualified lead often ends up comparable or higher than Google despite the lower CPC.
When to Choose Google Ads First
Google is the right starting point when: people actively Google your service when they need it, you need leads quickly with a limited budget, your sales cycle is short to medium, and your service solves an urgent problem. BEE consulting, OHS, ISO certification, payroll outsourcing, IT managed services — all fit this profile perfectly.
When Facebook Ads Makes Sense
Facebook becomes powerful once you have a well-converting website, a lead nurturing process, and a retargeting audience built from your existing traffic. Running Facebook Ads before these foundations are in place is expensive and frustrating. It's a second-layer channel, not a foundation channel — for most SA B2B businesses.
The Recommended Sequence
Start with Google Ads to generate immediate, high-intent leads. Use those leads to refine your sales process and build case studies. Layer in Facebook retargeting once you have an audience to target. Add LinkedIn for outbound prospecting in parallel. Build SEO content for long-term organic growth. Each layer makes the next one more effective.

Frequently Asked Questions
Which is better for B2B leads in South Africa — Google or Facebook?
For most B2B service businesses, Google Ads delivers higher quality leads faster. Facebook is better suited as a retargeting and awareness channel once your Google Ads foundation is working.
What is a realistic cost per click on Google Ads in South Africa?
For B2B service keywords, expect R15–R80 per click depending on competition. Niche sectors like BEE consulting or ISO certification can reach R100+ per click for top positions.
Can I run both Google and Facebook Ads at the same time?
Yes, but only if your budget allows for meaningful spend on both. Splitting a small budget across two platforms produces weak results on each. Concentrate on one until it's profitable, then expand.
Why don't Facebook Ads work for my B2B business?
Common causes: targeting too broad an audience, sending traffic to a website that doesn't convert, expecting immediate sales intent when Facebook is a brand-building channel, and not running retargeting alongside prospecting.
How much should I spend on Google Ads in South Africa?
R3,000–R5,000/month in ad spend is enough to generate meaningful data and leads in most SA B2B sectors. Below R2,000/month, the data volume is too low to optimise effectively.
