A Swiss business that wants more customers quickly faces two options often framed as competitors: buying leads from a specialised provider, or running its own Google Ads campaigns to capture demand directly on the search engine. Both aim at the same goal — connecting your business with people looking for your services — but they rest on very different economic and operational logics. Confusing them, or picking one without understanding the other, means risking spending in the wrong place.
This dossier isn't here to dismiss Google Ads in favour of buying leads: both have their place, and many businesses end up using both. The goal is an honest comparison from the concrete standpoint of a Swiss B2B buyer: what each channel truly costs (beyond the headline price), the skills it demands, the level of control and risk it implies, and the nature of the customer intent it generates. By the end, you'll have a clear decision framework to know which suits your situation — or how to combine them intelligently.
Two opposite economic models: cost per lead vs cost per click
The fundamental difference lies in when you pay and what you get in return. With Google Ads, you pay per click: every time someone clicks your ad, your account is charged, whether or not they contact you afterwards. You're not buying a prospect, you're buying a visit to your website — and it's up to that website to turn the visitor into a concrete request. With buying leads, you pay for the outcome: you're charged only when a qualified request, with contact details and a stated need, is actually delivered to you. The risk of "paying for nothing" is structurally different.
This distinction has direct consequences. On Google Ads, part of your budget mechanically funds clicks that lead nowhere: browsers, comparison shoppers, people who clicked the wrong result, competitors monitoring the market. That's the normal cost of the model, not an anomaly. With buying leads, that filtering is done upstream: in principle you only receive requests matching your criteria. In return, you lose direct control over volume and depend on the provider's ability to generate those requests. Neither model is "cheaper" in absolute terms: they simply shift risk and effort to different points in the chain.
What each channel really demands of you
Google Ads is often presented as accessible to everyone, and it is — for opening an account. Making it profitable is another story. A high-performing campaign requires choosing the right keywords, writing ads that convert, excluding irrelevant searches, building polished landing pages, setting up conversion tracking, and continuously adjusting bids. In Swiss B2B, you also have to handle local specifics: languages (French, German, Italian), cantonal targeting, competition on keywords that can be expensive. Without these skills — in-house or delegated to an agency — a Google Ads budget quickly dilutes. It's a powerful but demanding channel that rewards expertise and punishes amateurism.
Buying leads shifts that effort. The marketing skill (attracting demand, qualifying it) is carried by the provider; what's left for you to master is the sales handling of the leads received: calling back quickly, running the conversation well, turning the request into an appointment. That's not nothing, but it's a skill most tradespeople and SMEs already have, unlike bid management. For a business with no marketing team, this difference is decisive: buying leads requires knowing how to sell, Google Ads requires knowing how to advertise on top of knowing how to sell. So the question isn't purely financial, it's also about the skills available within your company.
Predictability, control and financial risk
These two channels behave differently in the face of uncertainty. Google Ads offers very fine control but a volatile result: you decide the daily budget, the areas, the schedules, but the real cost of a contact depends on an auction that fluctuates with competition, season and the quality of your account. One month can cost noticeably more than another at equal volume, and an aggressive competitor can push up costs in your sector overnight. You control the spend, less so the return on that spend.
Buying leads reverses the relationship. You have fewer fine-tuning levers, but a clearer link between what you pay and what you get: a delivered lead is a delivered lead, with criteria known in advance. The risk shifts towards quality and exclusivity — a shared lead means direct competition, a poorly targeted lead converts poorly — rather than towards volatility in unit cost. For a small business whose cash flow tolerates surprises badly, this relative predictability is a serious argument. For a business able to absorb variation and steer finely, the flexibility of Google Ads can instead become an asset. The right choice therefore depends as much on your risk tolerance as on the channel itself.
Quality and intent: who you actually reach
A click and a lead don't represent the same level of customer commitment. On Google Ads, intent depends entirely on the query typed: someone searching "emergency repair" has strong intent, someone looking for general information much less. You capture the whole spectrum, from the curious to the ready-to-sign customer, and it's your website and responsiveness that do the sorting. Well set up, it's a channel able to catch demand at the exact moment it's expressed. Badly set up, it mainly brings lukewarm visitors you pay full price for.
A purchased lead, by contrast, has already crossed a threshold: the person filled in a form, described their need and agreed to be contacted. Intent is in principle more mature and, above all, more legible, since you know the need before the first call. The trade-off comes down to two key points. First, freshness and callback speed: a shared lead is often approached by several professionals, and the advantage goes to whoever calls back fastest. Second, the traceability of consent, governed in Switzerland by the nLPD, which must be impeccable on the provider's side. Understanding how a provider qualifies and scores its leads is decisive here — it's the subject of our dedicated dossier on quality and scoring, worth reading before comparing two offers on price alone.
How to choose — or combine both
There's no universal answer, but a few clear markers. If you have no in-house advertising skill, no budget for an agency, and no time to learn, buying leads is often the fastest and least risky starting point: you focus on what you know how to do, sell, while the provider carries the technical part. If, on the other hand, you have real command of digital marketing, or a competent partner, and you want to build a durable asset that belongs to you, Google Ads deserves the investment — provided you accept a learning curve and a share of "wasted" spend at the start.
In practice, many Swiss businesses don't choose: they combine. Buying leads fills the pipeline quickly, smooths slow periods and tests the profitability of a sector or area without a heavy commitment; Google Ads is built in parallel, more slowly, as a foundation channel once the skills are acquired. The combination has an often-underrated advantage: it gives you a real point of comparison. By measuring, over the same weeks, your conversion rate and acquisition cost on each channel, you stop reasoning by intuition and arbitrate on figures that are your own. It's this discipline of measurement, more than the initial choice, that distinguishes businesses that make their acquisition pay from those that merely endure it. Whatever the starting point, start small, measure, then reallocate towards what actually works for you.
