Google Ads and Meta Ads are the two giants of paid marketing, but they solve different problems. Google captures people already searching for what you sell; Meta creates demand by putting you in front of people who weren't looking yet. Pouring your whole budget into the wrong one is one of the most common — and expensive — mistakes we see. Here's how to choose.
Intent vs discovery
Google Ads is intent-based: someone types "emergency plumber near me" and you appear at the moment of need. The demand already exists — you're competing to capture it. Conversion rates are high because intent is high.
Meta Ads (Facebook and Instagram) is discovery-based: people aren't searching, they're scrolling. You interrupt with something compelling to create demand that wasn't there a second ago. It's unmatched for building awareness and selling visual, impulse-friendly products.
How each finds your customer
Google targets keywords — the words people search — plus location and device. You reach people by what they want right now.
Meta targets people — interests, behaviours, demographics, lookalikes of your existing customers. You reach people by who they are. That makes Meta powerful for reaching a defined audience before they're actively shopping.
Cost and conversion
Meta typically has a lower cost per click, because you're buying attention rather than intent — but those clicks convert at a lower rate, since many viewers weren't looking to buy. Google's clicks cost more but usually convert better, because the person is already in-market.
Neither is "cheaper" in isolation — what matters is cost per acquisition and return on ad spend. A pricier Google click that converts can easily beat a cheap Meta click that doesn't, and vice-versa for the right product.
Which fits your business
As a rule of thumb:
- Lean Google if you sell a service people actively search for (legal, medical, repairs, B2B software, "near me" trades) or need demand you can capture today.
- Lean Meta if you sell visually-driven or impulse products (fashion, food, D2C, lifestyle), are launching something new, or need to build brand awareness and demand.
- Run both if budget allows — Meta to create demand and warm an audience, Google to capture that demand when they later search for you by name or category.
How to split the budget
Start where the intent is. For most lead-gen and service businesses, begin with Google to capture existing demand, then add Meta to expand reach once you know your economics. For D2C and visual brands, flip it: build demand on Meta, then capture branded searches on Google.
Whatever the split, test with a real budget for long enough to gather data, judge on cost per acquisition rather than clicks, and shift spend toward whichever channel returns more. The cost-per-lead calculator below helps you compare the two on equal terms.
Frequently asked questions
Should I use Google Ads or Facebook Ads?
Use Google Ads when people actively search for what you sell — it captures existing, high-intent demand. Use Meta (Facebook/Instagram) Ads to create demand for visual or impulse products and to build awareness. Many businesses do best running both: Meta to warm an audience, Google to capture them when they search.
Which is cheaper, Google or Meta ads?
Meta usually has a lower cost per click, while Google clicks cost more but tend to convert better because the intent is higher. The channel that's actually cheaper is the one with the lower cost per acquisition for your business — which you only learn by testing both with proper tracking.
How much budget do I need to test both?
Give each platform enough budget and time to exit the learning phase and produce statistically meaningful results — typically a few weeks of consistent spend per channel. Testing too little for too short a time is the most common reason paid campaigns are wrongly judged a failure.
