Facebook ads vs Google ads: which one fits what you sell

Introduction

The two platforms are not really competitors. They solve different problems, and most arguments about which is better are actually arguments about which problem a business has.

Google captures demand that already exists. Meta creates demand among people who were not looking. Knowing which you need is the whole decision.

1. Facebook ads vs Google ads: the core difference

On Google, someone types what they want. You are paying to appear at a moment of stated intent — the person has a problem and is actively seeking a solution.

On Meta, nobody was looking for you. You are paying to interrupt attention and create interest that did not previously exist. The targeting is based on who someone is and how they behave, not what they just searched for.

That difference drives everything else: cost, creative requirements, and how quickly results appear.

2. When Google is the better starting point

Choose Google first when people already search for what you sell.

Emergency and urgent services are the clearest case — nobody is persuaded into needing a locksmith by a video. So are established categories where the customer knows the product exists and is comparing options, and businesses with strong local intent, where "near me" searches carry real volume.

The advantage is efficiency: fewer wasted impressions, and demand you did not have to manufacture. The constraint is that you cannot exceed existing search volume. If only a hundred people a month search for what you do, Google caps you at a hundred people a month.

3. When Meta is the better starting point

Choose Meta first when your customer does not know to look for you.

New products and unfamiliar categories need demonstration before anyone searches for them. Visual and impulse purchases benefit from being shown rather than described. Broad-appeal offers, where the target is defined by lifestyle rather than by a specific need, fit Meta's targeting far better than a keyword list.

The advantage is scale — audiences are enormous and not limited by search volume. The constraint is that creative carries all the weight. A mediocre advert on Google still catches someone who was already looking; a mediocre advert on Meta is simply skipped.

4. What each actually costs

Cost per click tends to be lower on Meta. Cost per customer is the number that matters, and it frequently favours Google, because clicks from a search carry intent and clicks from a feed often do not.

Neither platform is reliably cheaper. Anyone quoting a universal figure is describing their own category, not yours. The only way to know is to run both against a defined offer and compare cost per customer against what a customer is worth to you.

5. The creative burden is very different

This is the practical difference that catches people out.

Google search ads are text. They can be written once and refreshed occasionally, and performance depends more on keyword selection and landing pages than on wording.

Meta consumes creative continuously. Performance decays as an audience sees the same advert repeatedly, so you need a steady supply of variations. If you cannot produce creative regularly — or build it in modular pieces so variations are cheap — Meta will get expensive as performance decays and nothing replaces it.

Be honest about this capacity before committing. It is the most common reason Meta campaigns underperform.

6. On a limited budget, do not split it

The most common mistake is running both platforms simultaneously on a small budget. Neither accumulates enough data to optimise, and you learn nothing about either.

Pick the one that matches your situation using the tests above. Run it long enough to gather real conversion data. Get cost per customer below what a customer is worth. Then, once that channel is working and funded, consider adding the second.

Sequential beats parallel when budgets are small, because the constraint is information rather than money.

Conclusion

Google captures demand; Meta creates it. If people are already searching for what you sell, start with Google, because harvesting existing intent is cheaper than manufacturing new intent. If they are not, Meta is the only one of the two that can help.

Judge both on cost per customer against customer lifetime value rather than on cost per click, and be realistic about whether you can feed Meta the creative volume it needs. On a small budget, commit to one and make it work before adding the other.
