Google Ads vs Meta ads: intent versus interruption

The comparison everyone runs is the wrong one

Search "Google Ads vs Meta ads" and you get feature tables. Audience targeting options, ad formats, reporting depth, average costs. All accurate, all beside the point, because you will not choose a platform based on whether it offers carousel ads.

There is one real difference and everything else follows from it. On Google, somebody typed something. On Meta, nobody asked for anything. Intent versus interruption. Once you know which of those matches how people come to buy what you sell, the decision is close to made.

What Google is actually selling you

Google sells you the moment someone has already decided they need a thing and is trying to find who provides it. The demand exists before you show up. You are competing for who gets called, not for whether anyone calls.

That is enormously valuable and priced accordingly. You’re paying for pre-formed intent, and so is everyone else in your category, which is why click costs in high-value industries get where they get. But the person clicking has a problem right now. They are not browsing.

The catch is that Google can only sell you demand that exists. If nobody searches for what you do, there is nothing to buy. No budget fixes that.

What Meta is actually selling you

Meta sells you attention from people who were doing something else. They didn’t search. They were scrolling and your ad appeared between a friend’s photo and a video. Your job is to make them stop.

That means Meta can create demand rather than just capture it. Someone who did not know they wanted a bus tour for their daughter’s wedding party can be shown one and want it. Google could never have sold you that person, because they were never going to type it.

It also means the bar for the creative is much higher. On Google a competent ad that matches the search wins. On Meta a bad ad simply gets scrolled past, and the budget goes with it.

The rule, plainly

Ask one question: when somebody needs what I sell, do they type it into Google?

If yes — the pipe burst, the arrest happened, the tooth broke, the car needs a tow — start with Google. The demand is there and searchable, and you are buying people at the exact moment they are ready.

If no — if what you sell is something people would enjoy but would never think to look for, or something they don’t know exists, or something bought on impulse or emotion rather than urgency — start with Meta. There is no search volume to capture, so you have to go and find people.

If the honest answer is "sometimes both", start with Google anyway. Capturing existing demand is a shorter path to a first result, and a first result buys you the patience to test the harder channel.

Where each one fits, concretely

Some examples from the kinds of businesses we actually work with.

• A family law firm — clearly Google. Nobody scrolls into a divorce. When it becomes real, they search, and they search that week.
• A luxury van and bus tour operator — mostly Meta. Some people search for a shuttle. But the wedding party, the birthday, the wine tour with friends — those are ideas somebody has to be given, and a photo of the vehicle does more selling than any keyword.
• A salon adding a new service — Meta first. Existing clients and local lookalikes need to be told the service exists before anyone can search for it.
• A trucking company — Google, narrowly. The searches are few but they are enormous, and the person searching is a buyer, not a browser.
• Emergency and after-hours anything — Google, and nothing else, until you’ve saturated it.

Retargeting is the exception to the rule

One place Meta earns its keep regardless of your category: showing ads to people who already visited your website. That’s not interruption in the usual sense. Those people demonstrated intent — they just didn’t act on it.

It is usually the cheapest ad money in the account, because the audience is small and already warm. If you are running Google Ads at any real volume and not retargeting the visitors who didn’t convert, you are paying full price for the same person twice.

The two platforms fail in completely different ways

Knowing the failure modes helps you tell which platform is wrong for you and which one you’re just running badly.

Google fails quietly and expensively. The account keeps spending, the clicks keep arriving, and the money leaks into search terms you never chose — people researching, people looking for a job, people in the wrong city, people who wanted a free version of what you sell. Nothing looks broken. You have to go and read the search terms report to find it, and almost nobody does.

Meta fails loudly and fast. The creative doesn’t stop anyone, the click-through rate collapses, the platform quietly stops showing your ad much, and the reporting makes it obvious within a week. That is unpleasant but it’s honest. You know quickly that the ad is the problem, which is more than Google usually tells you.

The practical consequence: a Google account needs regular pruning more than it needs new ideas. A Meta account needs new creative more than it needs settings work. Budgeting your own attention accordingly matters as much as budgeting the money.

What each platform needs from you

Neither one is set-and-forget, but they ask for different things, and the ask is worth knowing before you commit.

• Google needs a page that matches the search. The click is expensive and pre-qualified; the fastest way to waste it is to dump the visitor on a general homepage.
• Meta needs images or video that are worth stopping for. Stock photography reads as an ad and gets scrolled past. Real photos of your actual vehicles, room, staff or work do far better.
• Google needs someone to read the search terms report every couple of weeks and cut what shouldn’t be there.
• Meta needs new creative on a schedule, because the same ad shown to the same audience stops working — the platform calls it fatigue and it is real.
• Both need the phone answered. Neither platform can help you with that, and it undoes both of them equally.

Don’t split a small budget across both

The most common mistake we see is a business with a modest budget running both platforms at once so as not to miss anything. What actually happens is that neither campaign gets enough volume to produce a readable result, and you end up with two inconclusive experiments instead of one clear answer.

Pick the one the rule points at. Fund it properly. Get to a result. Then decide whether to add the second one with money you didn’t have to take away from the first.

Both of them rent the audience

Worth saying, since we sell an alternative and should be upfront about the bias. Everything you get from either platform stops the moment you stop paying. That is not a criticism — it’s just what advertising is. You are renting access to people you don’t have a relationship with.

The reason we push clients toward owning a list as well is that the rented audience never accumulates. Spend ten thousand dollars on ads over a year and in month thirteen you start from zero. That is a real cost, and it is invisible on the platform dashboard, which only ever shows you this month.

How to decide this week

Open Google’s Keyword Planner and look up the three phrases you think a customer would type. If there is meaningful search volume in your city, that is your answer and you should go and capture it. If the volume is negligible, you have just learned that Google cannot sell you what doesn’t exist, and Meta is where you find people instead.

That check takes fifteen minutes and costs nothing, and it settles an argument most businesses have for months.
