How to Build an Agency Website, Structure, Content, Examples

Agencies face a particular problem, because their website is a work sample and a sales conversation at the same time. This guide shows how the two fit together while the site stays focused on the client.

An agency website has to do two things at once. It has to show what the agency can do and explain what it offers. Many agency sites solve only the first. They look excellent and leave the visitor, two minutes in, wondering what is actually being sold here.

This guide walks through the structure that brings both together.

The core question first

Before a single page exists, settle one thing. Which inquiry is this website supposed to bring in?

Agencies that offer everything get inquiries for everything, mostly for the wrong things. Agencies with a clear focus get fewer inquiries and more of the right ones. The focus may be broad, but it has to fit into one sentence.

The page structure

For most agencies, eight to ten pages are enough.

Homepage. What you do, for whom, one piece of proof, a clear next step.
One page per service. Separate pages rather than one services page with sections. Someone looking for brand development should not have to scroll past performance marketing, and Google can only rank what has its own address.
Case studies, one page each. The most important format on an agency site.
About us. The people, the way you work, why you exist.
Contact. With a concrete way in, more than just a form.
Legal notice (Impressum, required in Germany) and privacy policy.

What a good case study contains

Case studies are the reason someone gets in touch. This is the structure that works.

The starting point. What the problem was, in one sentence, from the client’s point of view. Not “Relaunch of the corporate website”, but “Sales was getting inquiries from people outside the target group”.

The brief. What was supposed to change.

The approach. This is where you show how you think. It is the part that sets you apart from others, and it is the one most often left out.

The result. With a number, if possible. If no number has been cleared for publication, then a verifiable observation, for example that the kind of inquiries changed.

A client quote. With name and role.

Three cases like these make a stronger impression than twenty logos in a row.

The pricing question

Most agencies do not state prices. That costs more than it protects.

Without an order of magnitude you hold first calls with prospects who have a tenth of the budget, and both sides lose an hour. One sentence is enough. “Projects typically start at €8,000” or “Retainers from €2,500 a month”.

Write that, and you get fewer inquiries and more of the right ones. That is exactly the goal.

The most common mistake

Agency sites tend to talk about the agency. “We are a collective of strategists, designers and developers” describes you, but it solves nobody’s problem.

The test goes like this. Strike every sentence on your homepage that starts with “We”. What remains is the part written for the visitor. If nothing remains, you have found the most common mistake.

The three routes to a finished site

Build it yourself. The obvious choice, because you know how. The catch is familiar. Your own project never has priority, and many agency sites sit half-finished for years.

Commission it internally like a client project. With a brief, a deadline and someone responsible. That works, but it takes real capacity.

Use a finished template as the foundation. Structure, case study layout and service pages are in place, and you bring in content and design. That is the pragmatic route for agencies whose time is better spent on client projects.

After launch

Keep the case studies up to date. After every completed project, while the numbers are fresh. Agency websites almost always go stale at exactly this point.

Watch the service pages. Which one brings in inquiries? It often turns out that a service treated internally as a side line generates the most inquiries.

Sharpen the focus. The website is where positioning shows first. If the inquiries do not fit, the cause is almost always the first line.

Every one of the agency website templates is in the marketplace, each with service pages and a case study structure. Consultancies that sell advice rather than creative work will find their comparison in the best website templates for management consultants. If you want to compare the routes by cost, the numbers are under what it costs to have a website built.

Frequently asked questions

How many case studies does an agency website need?

Three good ones are enough. What matters is the structure of starting point, approach and a result with a verifiable number. Twenty logos without explanation make a weaker impression than three cases that show how you think.

Should prices be on the agency website?

At least an order of magnitude. A sentence like "Projects start at €8,000" filters out exactly the inquiries that would cost you time anyway. If you keep prices entirely to yourself, you end up in first calls with prospects who have a tenth of the budget.

Does an agency need a blog?

Only if someone really looks after it. For agencies, case studies almost always work better than blog posts, because they are a work sample and proof at the same time.

How important is the design of your own website?

More important than in most other industries, because it is read as a work sample. But design ambition at the expense of clarity costs inquiries. Anyone who still does not know what you offer after two screens clicks away.
