Online marketing agency in Haarlem.

Agencies in the Netherlands currently charge hourly rates of between €75 and €175. That figure doesn't tell you much. A low rate for someone who is still learning the trade on your budget is more expensive than a higher rate for someone who does the right thing in half the time. And a campaign that runs on the wrong metric for three months costs more than any agency ever could.

That is why we prefer to work with fixed fee rates rather than with individual hours. That way you know in advance what the costs are and what you get in return. Our in-house Customer Journey Advertising training programme, in which your own marketer builds the advertising channel under our guidance, costs, for example, a one-off fee of €7,500. For full-service advertising and ongoing guidance, we create a bespoke package price, as that depends on your target audience, the number of channels and your media budget.

What is never included is the advertising budget itself. That goes straight to Google, Meta or LinkedIn and is separate from our fees. How much that should be depends on your target audience and your choice of channels. More on that below, because that is precisely where most campaigns fall flat.

If you want to reach a B2B audience, you have to be able to target a mix of job titles, company size and industry. That is only possible on LinkedIn. Unless that target audience is also actively searching for what you supply, because then Google Search comes into it.

If you have a story to tell that needs space, you need platforms that give you that space: Meta, YouTube, LinkedIn. In Search, you are limited to a few lines of text. Cramming a complex proposition into a search ad does not work, no matter how high you bid.

Advertising on LinkedIn is expensive, which makes this question decisive there. And some channels are demonstrably stronger in a certain phase, but precisely for that reason more expensive: every advertiser chooses them and the auction passes that cost on. The strongest channel is therefore not automatically the cleverest one.

According to Eugene Schwartz, someone who doesn't yet recognise their problem needs a different message than someone who is comparing three suppliers. The same advertisement for both works for neither.

Dual processing: the majority of your audience scans, feels and decides quickly. Only when you get past that first layer is there room for arguments.

Prospect theory and heuristics. Loss weighs heavier than gain, and people lean on rules of thumb. That changes how you formulate an offer.

Search captures existing demand. That is its strength, and immediately its limitation: if nobody is searching, there is nothing to harvest. With YouTube and Demand Gen, you can actually create demand within the same account, using completely different metrics. We let Performance Max run alongside where possible, but not without boundaries.

The channel that can handle the entire journey: prospecting with video to a cold audience, retargeting with proof, customer lists for repeat purchases. Strong if your target audience is broad and you have something to explain. Weaker with very specific B2B target audiences that you cannot slice by job title.

The channel where you can combine your job title, company size and sector most sharply. For B2B, sometimes the only route. Also the most expensive click of all: usually €10 to €20, or €4 to €6 if intentionally set up for volume. The question is always whether that precision is worth the difference in price.

Advertising in ChatGPT was rolled out in the Netherlands on 24 August 2026. Access is currently managed via OpenAI's Ads Solutions team and affiliated agencies. We have just started with this and are in the testing phase. Do not expect years of experience from us on this channel, but do expect us to figure it out thoroughly at the moment it matters.

Slow and cumulative, and the only layer that doesn't stop once you cut the budget. GEO, being discoverable in AI answers, partly follows the same logic: clear answers, quotable figures, a consistent description of who you are.

Often cheaper than a larger budget. If your ads work but your landing page doesn't, you're paying for traffic that you're turning away yourself. That's why we always look at where the traffic lands. See also our High Impact Marketingsite.

Managing solely by CPMs and CPCs is too expensive at current prices. You pay for reach and clicks without knowing what they deliver, and you miss out on the power of algorithms. They only become effective once they know what a good outcome is.

What we find with virtually every new client: conversions are indeed taking place, but they are not being measured. Either they are attributed to an undefined channel, or everything ends up as direct traffic. The result is poor attribution: you don't know which channel delivers what, and the algorithm receives incorrect signals.

Measurement has become more difficult in recent years due to privacy legislation and opt-ins. That is no reason to give up, but rather to modernise the setup. We work with server-side tracking and offline conversions, and we take into account that you cannot measure everything. A setup that pretends everything is measurable provides a false sense of security.

Setting up a campaign is just the beginning. The return on investment comes from what you do afterwards, and that is two things at once.

The first is feeding the algorithm the right data, so it finds more of the right people. Not more leads, but more leads that fit. Not more orders, but orders from customers who return more often or spend more. That difference lies in which signals you feed back.

The second is shifting budget from what doesn't work to what does work. In practice, campaigns keep running for months because they were set up at some point. That's precisely where the profit lies, and it costs nothing extra. That is the core of our Digital Budget Optimization.

We are not the right fit for everyone, and not every moment is the right moment. Three conditions largely determine that.

Through other channels, via your network, or there is demonstrable interest. If that is not yet there, then hiring an agency is too early. Advertising magnifies something that is already there; it does not create something out of nothing.

You start small and look for a proof of concept first. But as soon as that is in place, you need additional budget to stabilise and grow the results. If you don't do that, you'll nose-dive while taking off. Why that works like that.

Most purchases are not impulse buys. Depending on the channel and your decision-making cycle, you will see where you stand after two to six months. If you are looking for results within two weeks, then we are not the right partner for you.

And sometimes full service simply is not what you need. If you have a marketer on your payroll, then our in-house training programme often more logical: then that person builds the channel themselves, with us alongside them.

We look at your target audience, your offer and your current figures, and honestly tell you whether we think it will work.

Before anything goes live, we check whether your tracking is correct. Without that foundation, we cannot optimise.

Start small, focused on one clear outcome. What you can assess when.

Budget where it works, signals back to the algorithm, regular evaluation.
