How to Choose a Web Design Agency: A Checklist for Your First Call

What is a web agency, and what should it deliver?

A web agency is a company that plans, designs, builds and launches websites for clients and often looks after them afterwards. The titles vary: web design agency, web development agency, digital agency. What matters is which of the tasks below are in your contract and which are not.

• Planning, covering goals, audience and page structure.
• Design, covering layout, colours, fonts and imagery for desktop and phone.
• Content, covering texts, photos and video, written by the agency or supplied by you.
• Development, covering the build on a content management system or in custom code.
• Search set-up, covering page titles, structure and basic technical points for search engines.
• Launch, covering hosting, the domain connection, testing and going live.
• Care, covering updates, backups, security and changes after launch.

Some agencies do all of this. Others cover design and hand the development to partners. Ask who does what, because the person you meet in the first call may not be the one who builds your site.

How do you choose a web design agency?

Judge an agency by what it will deliver and hand over, and use its portfolio to check that it can do the work. Compare two or three agencies against the same checklist and get the answers in writing.

1. Know the goal of the site and who it is for.
2. Agree who writes the content and who decides the structure.
3. Test earlier work on a phone.
4. Clarify who handles the legal pages and consent tools.
5. Settle who owns the domain, the source code and the logins.
6. Choose a content management system you can live with.
7. Ask which running costs follow the launch.
8. Compare quotes by scope.
9. Agree the process, with approvals at each stage.

Each point has its own section below.

Does the agency understand what your site must achieve?

A good agency asks about your goal before it talks about design. A website that exists to produce enquiries needs different priorities from one that gives information or sells products.

• What should a visitor do on the site, and what counts as success?
• Who is the visitor, and how do they find you?
• Which pages answer the questions that come before a purchase or an enquiry?
• How will enquiries be measured after launch?

Ask the agency to restate your goal in its own words in the proposal. If the proposal talks only about look and feel, the goal has not been discussed.

Who decides the structure, and who writes the content?

Agree this before the design starts, because late or missing content often delays a launch. A site needs a structure that mirrors how customers look for you, and texts and images that answer their questions.

• Who writes the texts, and is German copy written or reviewed by a native speaker?
• Who supplies the photos, and are professional photos in the scope or do you provide them?
• Is there one page per main service, so that each can be found and understood by itself?
• Is the structure planned from your customers’ questions, or taken from a template?

A page for each audience or region works well when visitors arrive with a specific need. Helikum Security, a security service with operating regions in Berlin, Brandenburg, Leipzig and Mallorca, has one page for each region and a separate careers page, so customers and job applicants each find their own path. Our references (German) show the live site.

How fast and mobile-friendly will the site be?

Ask for evidence that earlier sites work well on a phone, and ask how speed is checked before launch. Google bases indexing and ranking on the mobile version of a site, so a weak phone version affects visibility as well as visitors (Google Search Central, mobile-first indexing).

• Is the design responsive, meaning one page that adapts to the screen? Google recommends this set-up.
• Does the phone version carry the same main content and headings as the desktop version? Content that only appears after a click or a swipe may not be seen by Google. Accordions and tabs keep a layout compact as long as the content stays in the page.
• Which measurements will be reported at handover? Core Web Vitals are Google-backed metrics for loading speed (Largest Contentful Paint), responsiveness (Interaction to Next Paint) and visual stability (Cumulative Layout Shift), and they are measured with real visitors (web.dev).
• How large are the images and videos, and how are they compressed?
• Can you open three earlier projects on a phone, on mobile data, and judge how quickly they respond?

One example from our own work is Hygiene Meister, a cleaning company in Berlin-Reinickendorf. In the new site, a hero video was reduced from 123 MB to about 4 MB, and the mobile Lighthouse score rose from 57 to above 90. That is a lab measurement from October 2026 and no promise for another site. It shows what to ask an agency to measure and to show you.

Who handles the legal pages on a German website?

Ask who writes, checks and updates the legal pages, because an agency may build the pages without writing their content. Pages such as the legal notice (Impressum) and the privacy notice, and consent tools for cookies and tracking, are planning points for any German site. What they must contain is a legal matter. Our article on website legal requirements in Germany lists the primary sources, and a lawyer can advise on your case. This section is not legal advice.

• Is the legal notice page part of the scope, and who supplies its content?
• Who writes the privacy notice, and who updates it when tools change?
• Which tools set cookies or load external services, and how does the site ask for consent where that is needed?
• Do forms collect only the data you need, and where does it go?
• Is an agreement on data processing with the agency or the hosting provider part of the offer, where it applies?

Lawyers and specialist providers write legal texts. An agency can place and connect them. Agree in writing who does which part.

Who owns the source code, the domain and the logins?

You should own the domain and hold administrator logins, and the contract should say in writing what you may do with the design, texts, images and code. Without this, switching agencies later can be slow or impossible.

Rights and licences are contract terms. Ask a lawyer to check anything you are unsure about.

Which content management system should the site use?

The right content management system (CMS) depends on who will edit the site, how often and which features you need. A CMS lets people without coding skills change texts and images. The table lists the usual families.

Ask the agency why it recommends a system, who else can maintain it and what a move to another system would involve. An answer that only names the tools the agency likes to use is incomplete.

What do running costs and maintenance include?

A website has costs after launch, and the quote should list them. They usually include the domain, hosting, updates, backups and security checks, and changes to content or features. Our guide on website costs in Germany shows how to add them up.

• Who installs updates, how often, and what happens if an update breaks a page?
• Where are backups stored, and how quickly can the site be restored?
• What does a small change cost, and which response time applies?
• Which licences renew each year, and who pays?
• What is the notice period for the maintenance agreement?

How do you compare quotes from web design agencies?

Compare the scope first and the price second. Two quotes with different totals often cover different things, such as the number of pages, who writes the texts, how many revision rounds are included and whether maintenance is part of the deal.

Send every agency the same one-page brief with a page list and a feature list, and ask each to price that list. Then check each quote for these items.

• A page list and a feature list, named one by one.
• Who provides texts, photos and logo, and by when.
• The number of design drafts and revision rounds.
• Usage rights and the handover of code and logins.
• System, hosting and domain, and who pays for each.
• Maintenance after launch and what it costs.
• Payment plan and acceptance criteria.
• Net or gross prices, and what is excluded.

What does a good process with approvals look like?

A good process has clear stages, and each stage ends with your approval. That way you see problems early and the agency can plan its work.

1. Briefing, covering goals, audience, content and deadlines.
2. Structure, with a sitemap and page outlines for your approval.
3. Design, with layouts for desktop and phone for your approval and a stated number of revision rounds.
4. Content, with texts and images delivered, reviewed and placed.
5. Build and tests, with pages checked on real devices and in several browsers.
6. Legal and consent set-up, with pages and tools connected and checked.
7. Acceptance, where you test the site against the agreed list and sign off.
8. Launch and handover, with go-live, logins, documentation and a short training session.
9. Review after launch, with results and fixes after a stated period.

Ask who signs off on your side, how long each approval can take and what happens to the schedule if feedback arrives late.

Which warning signs should you watch for?

• A proposal with one total price and no scope.
• No live examples that you can open, only mock-ups.
• Unwillingness to say who owns the domain, the code and the logins.
• A system that only the agency can operate, with no export.
• A promise of first place in search results. Search engines decide rankings, so no agency can promise one.
• No stated plan for maintenance or security after launch.
• Pressure to sign quickly, or a deposit requested with no written scope.
• Designs that look good on a desktop screen and are never shown on a phone.

Use the same checklist on us. Digital030 is a digital agency in Hohen Neuendorf, just north of Berlin. Our page on web design in Berlin describes the service, and the first call of 30 minutes is free, in English or German. We do not publish fixed prices. A quote follows the first conversation, once we know the scope.
