Comparing Meta Ads and Google Ads on cost per click is like comparing a fishing net to a spear on weight. They are not doing the same job. Google Ads is a demand capture system that puts you in front of somebody who has already typed a description of their problem. Meta Ads is a demand creation system that interrupts somebody who was not thinking about you at all.
Once you accept that, the comparison becomes useful. Here is how they differ on the dimensions that determine which one deserves your next dollar.
Intent and the shape of the buyer
Search intent is self-declared and time-bound. Somebody typing "emergency plumber Newcastle" has a problem right now, and the transaction will happen within hours. There is no persuasion required — only availability, credibility and speed of response.
Meta intent is inferred and latent. The same person scrolling on Sunday evening does not have a burst pipe. But they might be four months from renovating a bathroom, and a well-made video about what goes wrong when it is done cheaply plants a preference that surfaces later — often as a branded search that Google will happily claim credit for.
Cost, and the trap inside it
Meta clicks are dramatically cheaper. In most Australian service categories a Meta click sits somewhere between fifty cents and three dollars, while Google search clicks in the same categories run from fifteen to eighty dollars. That gap is why so many businesses conclude Meta is more efficient after one month.
The trap is what happens after the click. Google traffic converts at high rates because the person was already shopping; conversion rates of five to fifteen per cent on well-matched search terms are normal. Meta traffic converts at low single digits because most of it is still forming an opinion. Cost per qualified lead — the only number worth comparing — often lands much closer than the click prices suggest, and in high-intent categories Google frequently wins outright despite costing forty times more per click.
Never compare these platforms on cost per click. Compare them on cost per sales-accepted opportunity, measured in your CRM.
Targeting
Google's targeting is the query itself, supplemented by location, device, audience signals and schedule. Your control is exercised through keywords, match types and negative keyword hygiene — and negatives matter more than ever now that broad match and Performance Max decide much of the delivery for you.
Meta's targeting has moved decisively towards broad delivery. Detailed interest stacks have been de-emphasised, and the practical lever is now the creative itself: the ad determines who stops scrolling, and the delivery system learns from who converts. Custom audiences from your own data — customer lists, site visitors, video viewers, CRM segments — remain genuinely powerful and are where most of the remaining manual control lives.
What each platform demands of you
- Google demands structure: tight themes, disciplined negatives, strong landing page relevance, quality score maintenance, and conversion tracking that reflects real value.
- Meta demands creative: a steady production line of genuinely different concepts, refreshed every two to four weeks, in the formats people actually consume.
- Google punishes sloppy keyword hygiene with wasted spend on irrelevant queries.
- Meta punishes creative stagnation with rising frequency and quietly decaying performance.
Measurement
Google is easier to measure because the click and the conversion usually sit close together in time and the query is a strong signal of the buyer's state of mind. Meta is harder because a meaningful share of its influence never produces a click at all: people see, remember and act later through another channel. Combined with tracking prevention and consent, that means Meta's real contribution is systematically under-reported in last-click views.
The workaround is the same on both platforms. Push server-side events — the Conversions API for Meta, enhanced conversions and offline conversion imports for Google — send qualified-lead and closed-deal events back from the CRM, and use blended cost per acquisition plus periodic geo holdouts to judge the mix rather than trusting either dashboard.
Which to choose, by situation
Lead with Google when
- People already search for what you sell, in volume.
- Purchases are urgent or problem-triggered — repairs, emergencies, professional services.
- Your margin per customer absorbs a high cost per click.
- You need a fast, readable revenue result.
Lead with Meta when
- Your product is new, visual, or needs explaining before anyone would search for it.
- Search volume in your category is thin or the auction is unaffordable.
- You have strong creative capability or something genuinely interesting to show.
- You are building a brand position, not just harvesting this month's demand.
Sales cycle changes the answer too
Length of consideration is the variable most comparisons ignore. Where the decision is made in minutes — an emergency trade, a same-day booking, a low-cost impulse product — search dominates, because there is no window in which brand-building can operate. Where the decision takes weeks or months, the buyer will encounter several channels before they act, and a platform's last-click performance stops describing its contribution.
For those longer cycles, the useful discipline is to assign each platform a job and a metric that matches the job. Meta's job is to grow the pool of people who know why your approach is better, measured by reach against your target audience, branded search volume and the volume of new contacts entering nurture. Google's job is to convert the ready buyer at an acceptable cost, measured by impression share on high-intent terms and cost per sales-accepted opportunity. Judged against their own jobs, both platforms become manageable; judged against each other on a single blended dashboard number, one of them will always look like the loser.
The answer most businesses land on
Nearly every mature advertiser we work with runs both, because a search-only account is capped by existing demand and a social-only account hands the closing moment to whoever is bidding on the category. Fund search capture until impression share on your high-intent terms stops being the constraint, then invest above that line in demand generation, and judge the whole system on blended cost per acquisition rather than on either platform's self-report.
The platforms are not competitors for your budget. They are two stages of the same funnel, and the businesses that treat them that way pay less for each customer than the ones still trying to crown a winner.
