Google Ads and Facebook Ads (now Meta Ads, covering Facebook and Instagram) are the two biggest paid channels for small businesses — and they do completely different jobs. This guide gives you the one difference that matters, the two questions that decide which platform fits your business, and the mistake that wastes most Facebook budgets.
Key takeaways
- Google helps customers find businesses. Facebook helps businesses find customers.
- Use Google Ads when people already search for what you sell — it captures existing demand.
- Use Facebook Ads to create demand — putting an offer in front of a precisely targeted audience that wasn't looking for you yet.
- The biggest Facebook mistake: running hard-sell ads at people who are there to see their friends, not to buy.
- For most established businesses the real answer is both, doing different jobs in the same funnel.
What they have in common
Both are pay-per-click platforms: you create an ad and pay when someone clicks (or per thousand views on Meta). Both let you control spend to the rand, and both are fully measurable — you can see exactly how many people saw the ad, clicked it, and enquired. That's why they dominate small business marketing budgets. But that's where the similarities stop.
The only difference that makes a difference
Google helps customers find businesses. Facebook helps businesses find customers.
Google: capture existing demand
Millions of searches happen on Google every minute, and a chunk of them are people actively looking for what you sell. Google Ads puts your business in front of someone at the exact moment they type "plumber Pretoria" or "emergency dentist near me". The intent is already there — you're just making sure they find you instead of a competitor.
Facebook: create new demand
Meta knows its users' age, location, interests and behaviour — and lets you target ads accordingly. A mobile dog groomer can put an offer in front of pet owners in specific suburbs who never searched for grooming at all. Nobody was looking for you; you found them. That's the power, and also the catch: the intent isn't there yet, so the ad has to create it.
Two questions that decide the platform
1. Do people already search for what you sell?
If there's real search volume for your service — plumbing, dentistry, accounting, repairs — Google Ads should come first. If you sell something people don't know to search for (a new product, an impulse purchase, a niche offer), Meta is usually the better starting point.
2. Do you want leads now, or a pipeline?
Google Ads generates near-instant enquiries from people ready to buy — assuming your ads and landing pages are good. Meta is better at filling the top of your funnel: lead magnets, offers and awareness campaigns that turn into customers over weeks, not minutes. A roofing company offering a free leak inspection before the rainy season will fill a pipeline on Meta; the person whose roof is leaking right now is on Google.
The mistake that burns Facebook budgets
Hard selling to people who aren't shopping. Facebook and Instagram users are there for friends, family and entertainment — not to spend money. Pinpoint targeting tempts businesses into running "buy now" ads at cold audiences, and those budgets evaporate. If you want sales from Meta, go about it differently:
- Retargeting. Show ads to people who already visited your website but didn't enquire. They know you — a reminder, an offer or a bit more information is often all it takes.
- Lead offers and content. Promote something genuinely useful — a guide, an inspection, a quote — to build an audience you can convert later. Awareness first, sale second.
The honest answer: it's not either/or
For most established businesses, the two platforms work together: Google Ads captures the demand that already exists, Meta creates demand and recovers the visitors who didn't convert. If budget forces a choice, start where the intent is — usually Google — and add Meta once the funnel works. We run both: see how we approach Google Ads and Meta Ads.
