Hiring a web design agency is one of the larger checks a small business owner writes, and it is also one of the easiest to get wrong. The market is crowded with shops that promise the world, deliver a template, and disappear after the deposit clears. This guide walks through how to evaluate a web design agency the way a careful buyer should — what to look at, what to ask, and what to walk away from.
If you are still deciding whether a new site is worth the spend, our guide to why web design matters covers the cost of a bad site in revenue terms.
Start With the Portfolio — Live Sites, Not Mockups
The first thing to look at is the agency's portfolio. But not the curated grid of pretty screenshots on their homepage — those are easy to fake and tell you nothing about performance. Ask for three live URLs the agency has shipped in the last twelve months, then open each one on your phone.
You are checking for:
- Load speed. Does the page appear in under two seconds, or do you stare at a blank screen? Mobile LCP is a real metric, not a vibes check.
- Mobile layout. Does the text reflow, or are you pinch-zooming to read a desktop layout squeezed onto a phone?
- Visual consistency. Does the site look like a coherent brand, or like a stock template with a logo dropped in?
- Function. Fill out the contact form. Click a link. Does anything break?
If the agency cannot give you three live URLs, that is a red flag. A shop that ships real work is proud to show it.
Ask Which Framework and CMS They Build On
This question filters out template shops fast. A real agency will tell you the specific stack they use and why. A shop that hedges with "we use the best tool for the job" without naming one is almost certainly reselling Wix or WordPress templates with a custom header.
The modern answer for a custom build is a component framework — Next.js, Astro, or similar — paired with a headless CMS like Sanity or Contentful. That stack gives you fast page loads, editable content, and the ability to extend without a full rebuild. A WordPress or Wix site is fine for some businesses, but you should know what you are buying and what its limits are.
For a deeper look at why the framework choice matters, our post on how to choose a web developer in Kent covers the technical questions in more detail.
Press on Core Web Vitals and Performance
Google uses Core Web Vitals — Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint — as ranking signals. A site that loads slowly, shifts as it loads, or feels sluggish when tapped will rank lower and lose visitors.
Ask the agency directly: "What LCP do you target on mobile, and how do you measure it?" A serious answer is a number — sub-2s LCP is a reasonable target for a small business site — backed by a tool like PageSpeed Insights or Lighthouse. A non-answer ("we optimize everything") tells you they do not measure.
Check Accessibility — WCAG 2.1 AA
Accessibility is not optional. The Americans with Disabilities Act applies to websites, and an inaccessible site is both a legal risk and a worse experience for every visitor. A competent agency builds to WCAG 2.1 AA from the start — proper color contrast, alt text on images, keyboard navigation, and screen reader support.
Ask: "Do you build to WCAG 2.1 AA, and can you show me an audit of a site you shipped?" If the agency does not know what WCAG 2.1 AA is, walk.
Look at Their Process
A real agency has a process. It does not have to be elaborate, but it should exist. Look for something like:
- Discovery — a call or questionnaire to understand your business, customers, and goals before any design work starts.
- Design — wireframes or mockups for your review, not a final site dropped on you at launch.
- Build — development with your input, not a black box.
- Launch — deployment with post-launch monitoring, not "here is the link, good luck."
Ask how long each phase takes, what you are expected to provide, and what happens if you are not happy with the design. Agencies that cannot describe their process usually do not have one.
Ask About Post-Launch Support
The launch is the start, not the end. Sites break, content needs updates, plugins and dependencies need patches, and you will have questions. Ask:
- How long is post-launch support included, and what does it cover?
- What happens after that window — hourly, monthly retainer, or on-call?
- Who owns the code, the domain, and the content after launch? (The answer should be you, in writing.)
A shop that hands you a site and disappears is selling you a problem. A real agency is around for the work that comes after.
Get References — and Call Them
Ask for two or three references from clients in a similar industry or size. Then call them. A five-minute call tells you more than any testimonial on the agency's site. Ask:
- Did the site ship on the agreed timeline?
- Did it match what was promised?
- How was communication during the build?
- What happened when something went wrong?
- Would you hire them again?
If the agency will not provide references, that is a red flag. If the references all sound scripted, that is also a red flag.
Watch for the Common Red Flags
A few patterns should end the conversation:
- Guaranteed rankings. No one can guarantee a specific Google rank. Anyone who does is lying or selling links that will get you penalized.
- Refusal to put pricing in writing. You should know what the project costs before you sign.
- No contract. A real engagement has a scope, a price, and a timeline in writing.
- Pressure to decide today. A good agency is fine with you taking a week to think.
- A portfolio of stock templates. If every "client site" looks identical with a different logo, you are buying a template with a markup.
Where Local Knowledge Helps
For a Kent, Renton, Auburn, or Bellevue business, a local agency has a few real advantages. They understand the South King County market, can meet in person when a screen share is not enough, and they care about local search in a way a remote shop in another state does not.
Digital Project LLC is based in Kent, WA, and works with businesses across Kent, Seattle, Renton, Auburn, and Bellevue. Our builds run on Next.js 15 with TypeScript and Tailwind CSS, target sub-2s LCP, and ship to Vercel. We build to WCAG 2.1 AA from the start, handle WordPress and Wix migrations, and stay on for post-launch support. If you want to see how that works in practice, our web design services page lays out the stack and the process, and our about page covers who we are.
What to Bring to the First Call
You will get more out of the first conversation with any agency if you bring a few things:
- A one-sentence description of what your business does and who it serves.
- Two or three competitor sites you like — and what you like about them.
- A rough budget range. "I do not know yet" is a fine answer; "I will not say" wastes everyone's time.
- A list of pages you know you need (Home, About, Services, Contact is a common start).
- Any content you already have — logos, photos, copy, existing brand colors.
An agency worth hiring will use that input to ask better questions back. An agency that ignores it and pitches a fixed package is selling you a template.
The Decision
The right agency for your business is the one that answers your technical questions clearly, shows you live work, has a defined process, builds for performance and accessibility, and stays around after launch. Price matters, but a cheap site that does not rank, does not convert, and breaks the first time you need an update is the most expensive site you can buy.
If you want a conversation rather than a sales pitch, contact Digital Project LLC — we will talk through what your site needs to do, whether we are the right fit, and what the build looks like if we are.
