Why MarketingConcurrent

Three things we
genuinely do differently.

Not a collection of services, but a strongly defined way of working. This is what you won't get at every other agency, and why SMEs stay with us.
01
Proven track record

We know what works.
And what isn't.

Google Premier Partner, 8 years running, placing us in the top 3% of all Dutch agencies. We manage €60 million in ad spend per year and achieve an average ROAS of 7.4×. That scale and experience mean we don't have to guess what will deliver returns for you.

Premier Partner, 8 years · €60M /jr beheerd · Avg. ROAS 7.4×
02
AI as a foundation

AI woven into everything
what we do.

Most marketing agencies still use AI sporadically, as a separate tool, alongside their regular work. At MarketingConcurrent, AI is fundamentally woven into our internal processes and our services, partly thanks to our partnership with AIbove.

03
No contracts

Quality as the foundation
for long relationships.

Most agencies tie you down with long contracts. We don't. We believe in the quality of our work, and that is our basis for a long-term partnership, not the small print of a contract. Cancel monthly, always.

FAQ

Frequently asked questions.

Didn't find your answer? Ask your question directly to a strategist, usually a reply within 24 hours.

Ask your question
How quickly can we start?

Quickly. After a strategy call and approval of the quote, we usually begin onboarding within 1 to 2 weeks, after which campaigns go live shortly.

Do I get a dedicated point of contact?

Yes, a strategist is your fixed point of contact. Behind the scenes specialists work per discipline, but you always have one face for strategy, prioritisation and reporting.

Do I get access to my own accounts?

Always. Your advertising accounts are and remain yours. You have 24/7 access to your Google Ads, Meta Ads and your live reporting dashboard. If you ever want to stop, you hand nothing over, because everything is already in your name. We think that is simply how it should be.

Which platforms and shop systems do you work with?

We work daily with Shopify, Magento 2, WooCommerce, WordPress, Lightspeed and PrestaShop. Whether you are already on a platform or want to migrate: we know the tracking setups, data feed structures and pitfalls of every system. Not sure whether your platform fits? Ask us in your strategy call.

Which marketing budgets do you work with?

We manage marketing budgets from €500 to €500,000 per month, with some outliers above that. Whether you're just starting or already investing heavily: we tailor our approach to your scale and growth ambition.

Why choose an agency from Veenendaal?

Location says nothing about quality, but it does say something about accessibility. We are based centrally in the Netherlands on the A12, so Utrecht, Arnhem and the Randstad are an easy trip and visiting us does not cost you a day. And most of the work runs digitally anyway: your dedicated specialist is reachable by phone and WhatsApp, wherever you are.

When will I see the first results?

That depends on the channel. With SEA (Google/Microsoft Ads) you see traffic and data coming in within the first weeks. We usually make the first optimisation round on ROAS and CPA within 4 to 6 weeks. Meta and Social Ads are comparable: the first campaigns run within a week, and after 2 to 4 weeks we optimise audiences and creatives. SEO is a longer game. Expect 3 to 6 months for structural growth. We pick up technical fixes straight away, but building rankings takes time. CRO and A/B tests go live within 2 to 3 weeks, and with enough traffic you have statistically significant winners within 4 to 6 weeks. A website migration takes 4 to 8 weeks, with zero traffic loss as the goal. A new web design goes live in 6 to 10 weeks, and we measure the impact on conversion straight afterwards. We promise no miracles in week 1, but from day 1 you can see what we are working on via your live dashboard.

What if it doesn't work, can I stop?

Yes. We work without long contracts, cancellable monthly. We believe you stay with us because it works, not because you have to. In practice we work with our clients for an average of 3+ years. That says more than a contract clause.

What exactly is the "AI" layer, and what is it not?

It is a set of production-ready systems, built by our partner AIbove, that analyse your marketing data 24/7 and propose concrete optimisations. It is not a chatbot and never replaces your strategist.

What does it cost to work with you?

We work with a monthly management fee, depending on the size and complexity of your campaigns. No hidden costs, no setup fee. You pay your advertising budget directly to Google or Meta, it does not go through us. In the strategy call we discuss what a realistic investment is for your situation.

Do you also work internationally?

Yes, we run campaigns in 14 countries for our clients. NL and BE are our home market; beyond that we also work in, among others, DE, FR, UK, US and Scandinavia.

Do you work for companies based abroad?

Yes, we also work for companies based outside the Netherlands. A number of our clients are headquartered abroad. We switch effortlessly to English and have experience running campaigns in more than 20 countries, so the location of your company is no obstacle to a smooth collaboration.
