Hiring a web design agency is one of the bigger decisions you will make for your business this year. Get it right and you have a partner who helps you grow for years. Get it wrong and you end up with a site that misses the mark, paying for fixes that should have been included, and chasing replies that never come.
The good news is that most bad agency experiences are predictable, and most are preventable. Almost every horror story we hear has the same pattern behind it: not enough questions asked at the start, polite answers accepted at face value, and an assumption that everyone in the industry works to the same standards.
These are the 15 questions we would ask if we were on your side of the table, grouped by what each one is really trying to surface. Some look obvious. The interesting part is how the answers come out.
Questions About Fit and Experience
The first thing you are trying to work out is whether this agency understands businesses like yours, and whether the people you meet are the same people who will actually do the work.
1. Have you worked with businesses like ours before?
You are not looking for an exact industry match. A jewellery brand and a manufacturing business can share more web challenges than you might expect. What you are looking for is genuine understanding of similar problems: how the agency thinks about your kind of audience, the typical sales cycle, and the structure a site like yours usually needs.
If they cannot point to anything comparable, that is not necessarily a deal-breaker, but it does mean you should ask harder questions about how they will get up to speed.
2. Can we see examples of similar projects, including the results after launch?
A portfolio of beautiful screenshots tells you very little. What you actually need to know is whether those projects worked. Ask to see what happened after the site went live: did organic traffic grow, did enquiries increase, did the client see a return on their investment within the first few months. An agency confident in its results will have this information to hand: rankings improvements, conversion data, or client outcomes they can point to directly.
If the conversation stays at the level of how things look rather than how they performed, that tells you something.
3. Who will be working on our project, and will they stay on it from start to finish?
This is one of the most important questions on the list. In larger agencies, the senior people you meet in the pitch often hand the work to junior staff or freelancers you never meet. Worse, the team can change halfway through, taking all the context with them.
You want to know exactly who is doing the design, who is doing the development, who your main contact will be, and whether any of the work will be outsourced.
Questions About the Process
Once you know who you are working with, the next thing to understand is how they actually run a project.
4. What does your process look like, from first call to launch?
A clear answer tells you the agency has built a lot of websites and learned what works. You should hear something structured: discovery, design, development, content, testing, launch, then post-launch support. Each stage should have rough timings and clear deliverables.
A vague answer usually means the project runs on instinct rather than structure, and that is where deadlines slip, decisions get lost, and things quietly fall through the cracks.
5. How long will the project take, and what affects that timeline?
Most websites take longer than people expect, and content is almost always the bottleneck. A good agency will give you an honest range, name the most common causes of delay (usually content delivery and feedback rounds), and explain how they keep things moving when things slow down.
Be wary of timelines that sound too tight. A four-week build for a serious business website usually means corners are being cut somewhere.
6. How will we communicate during the project, and how often?
Project communication breaks down for the same reasons every time: no agreed cadence, no shared place to track decisions, and no clarity about who replies to what within what timeframe. The agency should have a clear answer about communication tools, regular check-in points, and response times.
If everything runs through ad-hoc emails between three different people, you are almost guaranteed to lose context at some point.
Questions About the Build Itself
These questions help you understand what you are actually getting under the bonnet.
7. What platform will you build it on, and why that one for our business?
The right answer should be specific to your situation. Webflow, WordPress and Shopify each have different strengths, and a good agency should be able to explain why a particular platform fits your goals, your team, and the way you want to manage the site going forward.
Watch for two warning signs: a niche platform that few other developers can support if you ever need to move on, or a platform chosen for the agency's convenience rather than the fit with your business.
8. How will you build the site for SEO, speed and mobile from day one?
SEO, performance and mobile design are not features you bolt on at the end. They are foundational decisions made during the build, and they are far cheaper to get right first time than to fix later. The agency should be able to talk you through clean page structure, fast load times, mobile-first design, and the technical basics like metadata, sitemap submission, and image optimisation.
You do not need a technical lecture. You do need to hear that these things are part of how they build, not something you would need to pay extra for once the site is live.
9. What is your approach to security, hosting and ongoing maintenance?
Websites that are launched and never updated become security risks over time. Plugins go out of date, certificates expire, software needs patching. The agency should have a clear position on how the site will be hosted, how security is maintained, and what happens if something breaks at 9pm on a Sunday.
If they cannot answer this without checking with someone, that is usually a sign that maintenance is treated as an afterthought.
Questions About Cost, Contracts and Ownership
This is where most surprises live, so the answers matter.
10. What is included in the price, and what counts as extra?
A clear quote should tell you exactly what is included: discovery, design, development, content entry, testing, training, launch support, and how many pages or templates. Just as importantly, it should tell you what is not included, so you can see where extra costs might appear later.
If the price feels suspiciously low, the gap usually gets made up through change requests during the build.
11. If we parted ways, what would we walk away with?
The answer should be: all of it. Full ownership of the site, the code, the design files, the hosting account, the domain, and every login. Any other answer means you are tied to that agency for the lifetime of the site, which gives them all of the power in the relationship.
This is one of the easiest questions to ask, and one of the most revealing.
12. What happens if we are not happy with the end result?
A vague reassurance such as "we will discuss it then" is not an answer. A real answer should specify how many rounds of revisions are included, what counts as a change and what counts as a fix, and what happens if you fundamentally do not like where the design has ended up.
Our own approach is a pre-launch satisfaction guarantee, which means we keep refining the site until you are genuinely happy with it before it goes live. Different agencies will do this differently, but the key thing is that there is a defined answer to this question, not a hopeful one.
Questions About What Happens After Launch
Launch is the start, not the end. These questions surface how the agency thinks about the long term.
13. How will you train us to manage the site ourselves?
You should not have to call your agency every time you want to update a paragraph or add a blog post. Good training, a clear handover document, and a CMS that is genuinely easy to use should leave you confident enough to manage everyday updates yourself.
Ask what the training looks like, who runs it, whether it is recorded, and whether you can come back with questions afterwards.
14. What happens when we want to add a new feature next year?
Businesses evolve, and websites need to keep up. A good agency offers genuine flexibility: ad-hoc support for small changes, a growth retainer for ongoing development, or a project-based quote for larger pieces of work. The key word is choice.
The warning sign is a one-size-fits-all retainer being the only way to keep working with them, which often means you end up paying a fixed monthly fee for fewer hours than you would actually use.
15. How will we measure whether the website is actually working?
A website without measurement is a hope, not a strategy. The agency should be able to talk about what success looks like for your project, what tools will be in place to track it (Google Analytics, Search Console, conversion tracking), and how you will know whether the investment is paying off.
If the conversation never gets beyond "it will look great", you are talking to a designer rather than a partner who understands business outcomes.
Final Thoughts
Asking the right questions before you commit gets the project off to the best possible start. You will know what the working relationship looks like, what to expect at every stage, and whether this is an agency you are genuinely aligned with - before any contracts are signed or briefs are written. The clearer the picture you build upfront, the more confident you can be in who you choose.
A good agency will welcome every question on this list. If you sense any reluctance, that itself is your answer.
