What I do
From strategy to report
With over a decade of hands-on advertising experience, your accounts are in good hands. I combine the industry's best practices with the latest AI automations and optimisations.
Media strategy
A tactical media plan based on a campaign briefing or an audit. We define the best channel mix for your media budget and goals, grounded in real research rather than channel habit.
Campaign setup
Lean, high-converting campaigns, built from a media strategy or a plain conversation. Best-practice structures, AI-assisted where it speeds things up — never as a shortcut around the thinking.
Optimisation
Weekly account monitoring and adjustments, with AI doing the heavy lifting on analysis so decisions are made on signal, not on gut feeling. A roadmap keeps the work compounding.
Reporting
Account performance at a glance: one-pager live dashboards or automated report decks, ready to present to your clients or stakeholders without an evening of copy-pasting.

How I work
From first call to live campaigns
We explore your current situation, define the issues and make a plan. You know where we stand at every step — and you can stop at any of them.

- 03 Scope & terms
Agreement
A clear agreement covering the scope of work, commercial terms, and the standard clauses: confidentiality, liability, data.

FAQ
Questions people ask before we start
Not in the list? Send a WhatsApp — you'll usually have an answer within the hour.
Who is this for?
Marketing teams and agencies that run paid media and want senior hands on their accounts without hiring one. Teams use Sluys to add capacity and expertise; agencies use it as white-label media buying behind their own brand.
Which channels do you manage?
Google Ads and Meta Ads are the core. Other paid channels — LinkedIn Ads, Microsoft Advertising — are in scope where they genuinely fit the media plan, not as a default line item.
What do the AI workflows actually do?
They take over the repetitive work: daily performance monitoring, anomaly alerts, report generation and optimisation planning. That frees the paid hours for the work that needs judgement — strategy, structure, testing. You'll see the difference in the pace of updates, not in buzzwords.
How does the collaboration work week to week?
You get a fixed number of focus days per week, fully dedicated to your accounts, with live communication during office hours and async communication around it. No ticket queue, no account manager in between.
Do I keep ownership of my accounts and data?
Always. I work in your accounts, under your ownership — ad accounts, analytics, audiences and history all stay with you, also if we ever stop working together.
Can I stop whenever I want?
Yes. The proposal defines the scope; ongoing work runs per calendar month and is cancellable with one month's notice. The results decide whether we continue — not a contract lock-in.
About
I'm Jeffrey van Sluijs
I'm a digital advertising consultant with over ten years of experience managing multi-million-euro campaigns for national and international A-brands in tech, automotive and electronics — from e-commerce to B2B, tech to real estate. First from media agencies such as Publicis Groupe and Candid, now independently.
With Sluys I help marketing teams and agencies in their daily advertising work, while deploying AI workflows that take over the routine. That frees up time for the work that actually moves the numbers.
For you that means one thing above all: you talk to the same person who builds and steers the campaigns. No account manager relaying messages, no junior doing it on the side.
