Google Ads or Meta Ads: one finds people already looking, the other interrupts
These two channels are not two ways of buying the same thing. One buys existing intent at whatever the auction charges for it; the other buys attention from people who were not looking and asks your creative to do the rest. The choice usually turns on whether anyone searches for what you sell.

The distinction
One channel asks people what they want and charges you to answer. The other decides somebody might be interested and charges you for the interruption. Almost every practical difference follows from that.
Search advertising is demand capture. The intent already exists, somebody has expressed it in words, and you are competing to be the response. The auction prices that intent, which is why the clicks cost what they cost.
Paid social is demand creation. Nobody was looking. Your advertisement has to establish that a problem exists, that a solution exists, and that yours is worth stopping for, in about two seconds, before anyone has agreed to be sold to.
The deciding question
Does search demand for what you sell actually exist?
Before comparing anything else, settle this. Some categories have obvious, high-volume, well-phrased search demand: emergency plumbing, replacement parts, accountants in a named city, a specific product model. Others have almost none, because the customer does not yet know the category exists, cannot name it, or would never think to look for it while it is not on their mind.
If demand exists, search is usually the first place to spend, because you are buying people at the moment they have decided to act. If it does not, Google will still happily sell you clicks — from broader, vaguer queries and from partner placements — and those clicks will be exactly as unqualified as the searches behind them. That is the most common way a search budget disappears in a category with no real search demand.
If demand does not exist, Meta becomes the more sensible starting point, because it is built to reach people who were not looking. The trade is that everything then depends on the offer and the creative, and neither of those is a media buying problem.
There is a middle case worth naming. Plenty of businesses have search demand for a category but not for what makes them different — the search is generic, the differentiation is not searchable. Those businesses often need both channels eventually, with search capturing the generic demand and social doing the work of explaining why you rather than the other seven results.
The two channels on the dimensions that change the decision
No scores and no averages. Each row is a genuine trade where one channel gives up something the other keeps.
| Dimension | Google Ads | Meta Ads |
|---|---|---|
| Who starts the interaction | The customer. They typed something, and you are competing to be the answer to it. | You. Nobody asked. The advertisement has to earn the pause before it can sell anything. |
| What you are actually buying | Existing intent, priced by an auction against everyone else who wants the same intent. | Attention within a feed, priced by how well your creative holds it against everything else in that feed. |
| What decides performance | Query selection and negatives, match type discipline, landing page relevance, and conversion data worth bidding on. | Creative concepts and the offer, tested in volume. Targeting is now largely automated and is not where the leverage is. |
| Ongoing production load | Low. A handful of ad variations per group, refreshed occasionally. The work is in the account, not the studio. | High and permanent. Concepts fatigue as the same people see them, so production is a standing cost, not a launch cost. |
| Measurement reliability | Comparatively good. The query is recorded, the click is attributable, and the search terms report shows what you actually bought. | Comparatively poor. Browser and app privacy changes cut the signal, and a share of reported conversions is modelled rather than observed. |
| Budget floor | Set by click prices in your category. In expensive verticals a small budget buys too few clicks to learn anything. | Set by the volume needed to test creative. A budget that only supports one concept cannot find the one that works. |
| How it fails | Expensively and quietly. A modest number of irrelevant clicks at a high price, often from broad match and partner inventory. | Cheaply and loudly. Plenty of cheap responses that look like success in the dashboard and never reach a sale. |
| Typical time to a verdict | Weeks, if the category has volume. The evidence arrives as search terms and enquiries you can read. | Longer, because you are judging a creative pipeline rather than a setting, and one concept proves nothing. |
| Where it is the wrong choice | Categories with no real search demand, and businesses whose differentiation cannot be expressed in a query. | Considered, infrequent, high-value purchases with a long cycle, and businesses that cannot sustain creative production. |
By business type
Four common situations, and which way each usually points
These are patterns rather than rules, and the exceptions are real. They are still a faster route to a shortlist than a feature comparison.
An urgent problem with a known solution
A boiler has failed, a tooth hurts, a lock is broken. The customer knows what they need and is searching for it right now. Search wins outright, and paid social spends money reaching people whose boiler is fine. The only competition here is the map pack and whoever answers the phone fastest.
A product people want once they see it
Visually driven, discretionary, often impulse-adjacent. Nobody searches for it because they do not know it exists. Meta earns its place because the feed can show the thing, and the creative can do the explaining that a text advertisement cannot.
A considered business purchase
Long cycle, several people involved, a small number of real buyers in the market at any moment. Search captures the few who are actively looking. Social and other paid channels do the slower job of being known before the search happens, and the reporting will never neatly separate the two contributions.
A local service people choose deliberately
A dentist, a law firm, a gym. Demand exists in search but is dominated by maps and reviews, so paid search competes against organic local results as much as against other advertisers. Social works for a different job here: being familiar before someone starts comparing.
Decide it yourself
Eight questions that settle this without an agency in the room
Answer these honestly and the shortlist usually reduces to one before anyone has quoted you for management.
- Can you write down five things a customer would actually type that describe what you sell?
- Would somebody buy this the first time they saw it, or does it need thinking about?
- Can your business produce several genuinely different pieces of creative every month, indefinitely?
- Do you know what an acquired customer is worth to you, not just what a lead costs?
- Can you record which enquiries turned into revenue, and match them back to a source?
- Is the purchase visual, or does it have to be explained in words?
- Is there a moment of urgency in the buying process, or is the timing entirely yours to create?
- If the answer is "both", is the budget genuinely large enough to run two channels above their learning thresholds?
If the answer is both
A sequence for adding the second channel without ruining the first
Most of the disappointment we see with a two-channel budget comes from starting them together and never knowing which did what.
Fix the measurement before the media
Decide, in writing, which system is the source of truth for a conversion, and make sure it records the source. If you skip this, you will spend the next six months arbitrating between two platforms that both claim the same sale, and you will make budget decisions on whichever dashboard was open.
You get: One named source of truth, and tracking that survives the whole journey
Take the first channel to a known cost per customer
Not a cost per click or a platform-reported conversion. A cost per customer you can reconcile with revenue. Until one channel has produced that number, adding a second one only makes the arithmetic harder to unpick.
You get: A defensible cost per acquired customer for one channel
Add the second with new money, not by halving the first
Splitting a working budget usually drops both channels below the volume their bidding systems need, which produces two underperforming accounts and a conclusion that neither works. If new money is not available, wait.
You get: An incremental budget with its own success condition
Give each channel a distinct job and judge it on that
Search captures existing demand and should be judged on cost per acquired customer. Social creates demand and should be judged over a longer window, with the honest acknowledgement that some of its contribution will show up as branded search and direct visits that nothing attributes to it.
You get: A written objective per channel, agreed before spend starts
Test the interaction deliberately
Once both are stable, turn one off for a defined period and watch what happens to the other and to total revenue. It is the only practical way to see the interaction, and it is uncomfortable enough that almost nobody does it. The result frequently changes the split.
You get: A documented holdout period and what changed during it
Questions
What advertisers ask when choosing between the two
Which one should we start with?
Start with search if people already type words that describe what you sell, and you can identify those words without stretching. Start with Meta if what you sell is something people would want once shown but would never think to look for, or if the purchase is visual and impulsive.
The test is not what your customers are like. It is whether the demand already exists in a search box. Look at the search terms report of any existing account, or run a small search campaign for a month purely as research.
Facebook ads did not work for us last time. Why try again?
Because "did not work" usually describes one of three separable failures: the offer was not compelling enough to interrupt someone, there were too few creative concepts to find one that landed, or the measurement never credited the channel for what it did.
None of those is a verdict on the platform. All three are worth diagnosing before writing off a channel, particularly the third, which is the one nobody checks.
Is Google Ads more expensive?
Per click, almost always. Per acquired customer, frequently not, because you are buying a person who has already declared what they want. A cheap click from somebody with no intent is not the better deal it appears to be in a report.
The comparison that matters is cost per acquired customer, and it requires tracking that survives the journey rather than platform-reported conversions from two dashboards that both claim the same sale.
Can we run both on a small budget?
Usually not well. Both channels need enough conversion volume for their bidding systems to learn from, and splitting a small budget often leaves both below that threshold, producing two accounts that never stabilise.
The more productive pattern is to get one working to a known cost per customer, then add the second with new money rather than by halving the first. If the budget genuinely cannot support one channel properly, the answer is not two.
Why do Meta and our own analytics disagree so badly?
Because they are answering different questions. Meta credits itself for conversions it can associate with an ad view or click within its own attribution window, including modelled ones. Your analytics credits the last thing that referred the visit, which is often a search for your brand name.
Both are describing something real. Neither is the truth, and the practical answer is to pick one internal source for decisions, hold the platforms to a directional role, and reconcile against actual revenue in your own records.
How much creative does Meta actually need?
More than most businesses expect, and continuously rather than once. Automation has absorbed most of the targeting decisions, which leaves the creative carrying the performance, and creative wears out as the same people see it repeatedly.
That makes production capacity a real selection criterion. If your business cannot sustain a steady flow of new concepts, that is an argument for putting the budget somewhere the creative does less of the work.
Not sure which one your business actually fits?
Tell us what you sell and what a customer is worth, and we will tell you which channel we would start with and why — including the cases where the honest answer is that neither is the priority yet.
