Adworth
Your Google Ads specialist in Amsterdam
Adworth Internet Marketing is a Google Ads agency serving Amsterdam and the rest of the Netherlands and Belgium since 2010. Owner Arno Kooijman manages every account personally, with a maximum of 25 clients.
Keywords and bids are controlled manually instead of relying on Smart Bidding or Performance Max. The focus is lead generation for B2B and service businesses, not e-commerce. Alongside Google Ads, Adworth provides SEO, conversion-focused web design, tracking (GA4, server-side) and hosting.

Google Ads
Google: where new clients find you

Think about it: how often is a Google search your first step when you need a specific product or service? Your future clients do exactly the same. With Google Ads you appear at the moment they are actively looking.

Billions of searches are made on Google every day. The challenge is not reach but relevance: showing up only for the searches that lead to real enquiries, and not paying for the rest.
Hands-on since 2010
Arno Kooijman started working with search engine advertising in 2010 and has managed Google Ads accounts for businesses across the Netherlands and Belgium ever since. He still does the work himself: no account managers, no juniors, no hand-offs.
That is a deliberate choice. By limiting Adworth to a maximum of 25 clients, every account gets the attention it needs, and you always speak to the person who actually makes the changes.

Why Adworth?
A different approach
Many agencies scale by automating everything and adding more clients. Adworth does the opposite. High quality work, not the cheapest option, but highly effective.

Manual control
Keywords, bids and search terms are managed by hand, so your budget goes to searches that bring leads.

Direct contact with the owner
You work with Arno himself. No account managers in between.

Your account stays yours
The Google Ads account is in your name. If you ever leave, all data and history stay with you.

Maximum of 25 clients
A small, fixed number of clients means time for every account, every week.

How Google Ads works for lead generation
Google Ads lets you show your ads at the top of the search results for the terms your clients use. You pay per click, so every euro should lead to a visitor who is likely to enquire.
That only works when the campaign structure, keywords, ad texts, landing page and conversion tracking are aligned. Adworth sets up and maintains that whole chain, so you can see exactly which searches produce leads.

The right keywords in Google Ads
More visitors alone do not grow a business. What matters is attracting the right visitors: people searching for exactly what you offer, in the area you serve.
Adworth researches your market, excludes irrelevant searches and reviews the search terms report every week. The result is fewer wasted clicks and a lower cost per lead.
- Measurable results
- Continuous optimisation
- Flexible when your market changes
Leads, not just clicks
Clicks and impressions are easy to buy. Adworth measures success by what reaches your inbox and phone: enquiries, calls and booked appointments, tracked reliably with GA4 and server-side tracking.

Frequently asked questions
What does a Google Ads agency in Amsterdam cost?
Every account is different, so Adworth works with a custom quote. You start with a free Google Ads scan, after which you receive a fixed monthly fee. You can cancel monthly.
Who manages my Google Ads account?
Owner Arno Kooijman manages every account personally, as he has since 2010. There are no account managers or juniors in between.
Do you use Smart Bidding or Performance Max?
Manual control is the default. Keywords and bids are managed by hand, and automation is only used where the data shows it performs better.
