Your website is often the first impression customers get of your business. Choosing the right web design agency can mean the difference between a website that brings in enquiries every week and one that looks nice but does nothing.
I've spoken to many business owners who've been let down by a previous web designer: sites they couldn't edit, didn't own, or that never appeared on Google. This guide covers the 10 questions I'd ask before hiring any web design agency, plus the red flags to watch for. You can see our own approach on our web design services page.
Why Choosing the Right Web Design Agency Matters
A website is a big investment of money and time. The right agency will understand your business, design around your customers, build a site that performs on Google and support you after launch.
The wrong one can leave you with a slow, hard-to-edit website, no SEO, and a bill to rebuild it within a couple of years. Asking the right questions upfront avoids that.
10 Questions to Ask a Web Design Agency
1. Can I see websites you've built for businesses like mine?
Ask for a portfolio and case studies, ideally in your industry. Visit the live sites yourself. Check how they look on your phone, how fast they load and how easy it is to get in touch.
2. Can I read genuine reviews?
Verified Google reviews from named businesses are far more reliable than testimonials on the agency's own website.
3. Will the website be built with SEO in mind?
This is the question many business owners forget. A website that isn't built for SEO may never appear on Google. Ask how they handle page structure, speed, metadata, mobile optimisation and schema. Our guide to SEO website design explains what to expect.
4. Who will own the website and domain?
You should own your domain name, your content and ideally the website itself. Be cautious of arrangements where you effectively rent the site and lose it if you leave.
5. Which platform will you use, and why?
WordPress, Shopify, website builders and custom builds all have pros and cons. A good agency will recommend the right platform for your needs rather than forcing everyone onto the same one.
6. Will I be able to update the website myself?
If you want to change prices, add photos or publish news, you should be able to do it without paying for every small edit.
7. What's included in the price?
Check whether the quote includes design, development, content, SEO setup, images, testing, training and launch support. Hidden extras can double the real cost.
8. How long will the project take?
Most small business websites take four to eight weeks. Ask for a timeline with clear stages and find out what they need from you.
9. What happens after launch?
Ask about hosting, maintenance, security, backups and support. See our guide to website maintenance costs for what's normal.
10. How will you measure success?
A good agency focuses on results such as enquiries, bookings and sales, not just how the site looks.
Web Design Agency Red Flags
Think twice if you hear: "We don't really do SEO", "You can't access the website yourself", "The domain will be in our name", or "We'll need full payment upfront before we start."
Other warning signs include:
- A portfolio full of sites that look almost identical
- Live portfolio sites that load slowly or look broken on mobile
- No questions about your business, customers or goals
- Vague quotes without a clear breakdown
- No mention of support after launch
- Prices that seem too good to be true (see our guide to website costs)
Web Design Agency vs Freelancer vs DIY
| Option | Pros | Cons |
|---|---|---|
| Web design agency | Broad skills (design, build, SEO, content), accountability, support | Costs more than a freelancer |
| Freelancer | Often cheaper, direct contact | Limited capacity, may lack SEO or development skills |
| DIY website builder | Cheapest upfront, quick to start | Your time, limited SEO and design control |
For most small businesses, a small specialist agency offers the best balance: a direct relationship with the people building your site, plus design, development and SEO skills under one roof. If you're weighing up DIY, read our guide to website builders vs professional web design.
What a Good Web Design Project Looks Like
Discovery. The agency learns about your business, customers, competitors and goals.
Planning. A sitemap, page structure and keyword plan are agreed, so the site is built to be found on Google.
Design. You see and feedback on the design before development starts.
Build. The site is developed, content is added and SEO foundations are put in place.
Testing. Speed, mobile, forms and links are all checked.
Launch and support. The site goes live with Google Search Console set up, and you get training and ongoing support.
Should You Choose a Web Design Agency That Also Does SEO?
In most cases, yes. Design and SEO are closely linked. Site structure, speed, content and code all affect how well you rank. An agency that understands both builds a website that looks great and gets found.
It also avoids the common problem of a designer building a site, then an SEO agency having to rework it later, which you'd pay for twice. At SERPentity, we do both web design and SEO, so your site is built to rank from day one.
How SERPentity Answers These Questions
I'm happy to be held to the same questions. Our results are public, with every case study backed by a real Google review. Every site we build is fast, mobile-first and built with SEO foundations. You own your website and domain, and you'll be able to update it yourself.
You'll work directly with me and my team, from the first conversation to launch and beyond. Sarah Senbeto, who needed a website for her new counselling business, told us she valued how quickly we responded and how patient we were, especially as IT isn't her strong point. Rogue said their site turned out far better than they'd anticipated.
Comparing Web Design Proposals
Once you've shortlisted two or three agencies, you'll usually receive proposals that look quite different. Compare the scope, not just the price. How many pages are included? Is content writing covered? Is SEO setup included, and what does it involve? What's the timeline, and how many rounds of design changes do you get?
Look for specifics. A strong proposal shows the agency has looked at your current website, understood your customers and thought about what your new site needs to achieve. A generic proposal that could apply to any business suggests they haven't.
Finally, consider the relationship. You'll be working closely with this team for several weeks, and hopefully for years afterwards. Choose people who listen, explain things clearly and make you feel confident about the project.
Final Thoughts
The right web design agency will ask as many questions as you do, because they want to understand your business before they build anything. Take your time, check their work and reviews, and choose a partner who cares about results, not just looks.
