The essentials
- One objective per campaign: leads, sales, qualified traffic or awareness; a campaign chasing two of them reaches none.
- The chain to follow: business objective, then measured conversion, then a numerical target (cost per conversion or ROAS), then bidding strategy.
- 2026 benchmarks: an acceptable cost per lead between 5 and 15% of the margin on a customer; a minimum ROAS equal to 1 divided by the gross margin (400% for a 25% margin).
- What does not count as an objective: clicks, impressions or a CTR, which describe delivery, not the result.
The first question Google Ads asks when you create a campaign is “What is your objective?”. The answer determines the bidding strategies offered, the networks switched on and the way the algorithm optimises. But the objective in the platform's sense is only a setting; the real objective is set beforehand, in euros and in volume. This article describes the chain that links the two and gives the benchmarks for putting a figure on a target. The distinction between objective, KPI and metric is covered in detail in KPI, metric and objective.
The four families of objectives and what they involve
| Objective | Conversion to measure | Numerical target | Suitable bidding strategy | Campaign types |
|---|---|---|---|---|
| Generate leads | Form, call of more than 60 s, appointment booking, quote | Cost per qualified lead | Maximise conversions, then target CPA | Search, Performance Max, Demand Gen |
| Sell online | Purchase with a value passed | ROAS or margin after advertising | Maximise value, then target ROAS | Shopping, Performance Max, Search |
| Bring in qualified traffic | Engaged visit (duration, pages viewed), sign-up | Cost per engaged visit | Maximise clicks with a CPC cap | Search, Display |
| Build awareness of a brand or a product | Complete view, reach, rise in brand searches | Cost per thousand impressions or per view, share of voice | Target CPM, CPV | Video, Display, Demand Gen |
A campaign pursues a single objective. A Search “leads” campaign that also counts page views as conversions optimises towards curious visitors and dilutes the real cost per lead. Remove secondary actions from the “Conversions” column; the setup is described in Google Ads conversions.
Setting the target from the economics of the business
The target is not set against a sector benchmark but from what a customer brings in. Two calculations are enough:
- Lead generation: average margin per customer × the rate at which a lead becomes a customer = expected margin per lead. The acceptable cost per lead is a fraction of that, generally 10 to 20% for a recurring business and 5 to 10% for a one-off sale. Example: €2,000 of margin per customer, 25% conversion to customer, so €500 per lead; at 10%, a target cost per lead of €50.
- Online sales: the break-even ROAS is 1 divided by the gross margin. With a 25% margin, a ROAS of 400% covers the advertising cost exactly; the target sits above that, for example 500 to 600%, to leave a net margin. The detail is in ROAS.
These targets are then measured against the market: if the average CPC in your sector is €4 and your conversion rate is 4%, the natural cost per lead is €100. A €50 target calls for either a better conversion rate, or less competitive queries, or a revision of the target. CPCs by sector in France are given in Google Ads: definition and how it works.
Realistic target benchmarks in 2026
| Business | Cost per lead or ROAS observed | Search conversion rate | Time before stabilisation |
|---|---|---|---|
| Tradespeople, call-outs, home services | €15 to €40 per contact | 5 to 10% | 4 to 6 weeks |
| Independent professionals, private healthcare | €25 to €80 per appointment | 4 to 8% | 6 to 8 weeks |
| B2B services, software | €60 to €200 per demo request | 2 to 5% | 8 to 12 weeks |
| Property, insurance, credit | €80 to €300 per lead | 3 to 6% | 8 to 12 weeks |
| E-commerce, average basket €50 to €150 | ROAS of 400 to 800% | 1.5 to 3% | 6 to 10 weeks |
| E-commerce, average basket above €500 | ROAS of 600 to 1,200% | 0.8 to 2% | 10 to 14 weeks |
Moving the objective on as the account matures
- Months 1 to 2: a data collection objective; “maximise conversions” with no target, a stable budget, measurement checked. The cost per conversion observed serves as the baseline.
- Months 3 to 6: a cost objective; target CPA or target ROAS set at the level observed, then tightened in steps of 10 to 15%. The switch is described in Smart Bidding.
- Month 6 and beyond: a volume objective at a controlled cost; raise the budget by 20% per step as long as the cost per conversion stays below the target, then move to a value objective (qualified leads, margin) rather than a number.
An awareness objective is not run with the same campaigns or the same timeframes; for a small business it is mainly justified when launching an offer, or alongside a conversion campaign that has reached its volume ceiling.
The objectives that waste budget
- “Be in first position”: position is not a result, and a target impression share is expensive on competitive queries.
- “Get 10,000 clicks a month”: easy to reach by widening the keywords, with no effect on sales.
- “Spend the whole budget”: an unspent budget on a profitable campaign is a signal to increase volume, not an objective to fix with broader keywords.
- “Beat the competitor on their brand”: legal but expensive, with a conversion rate often below 1%.

Frequently asked questions
Can you give the same Google Ads campaign two objectives?
Technically yes, by counting several conversion actions, but the algorithm then optimises towards the most frequent and the cheapest one, generally the least useful. One campaign per objective, with a single primary conversion action, gives readable results and makes management possible. Secondary actions stay visible as observation without weighing on optimisation.
Which objective should you choose when you cannot measure sales?
Move one level up the journey: a quote request, a call, an appointment booking or a measurable sign-up on the site. Set the target from the rate at which that step becomes a customer. With no measurable conversion at all, a qualified traffic objective with a CPC cap remains possible, but profitability will stay impossible to verify.
Do you need an awareness objective before a conversion objective?
Not for a small business whose offer is already searched for on Google: the Search campaign captures existing demand and pays for itself faster. Awareness is justified for launching a new offer nobody is looking for, or for widening demand when the conversion campaign has reached its volume ceiling at an acceptable cost.
How do you know whether your cost per conversion target is realistic?
Compare it with the average CPC in your sector multiplied by the inverse of a plausible conversion rate (3 to 7% for leads). If the target is below that result, it assumes a conversion rate above the market or cheaper queries. A two-month test with no target gives the real cost, from which the target can be set.
