What to Look for in a Web Developer Before You Hire

What to look for in a web developer comes down to five things: a portfolio of real, working sites, clear communication before you've even signed anything, a defined process with milestones, transparent pricing with no hidden line items, and a stated period of support after launch. Get those five right and the rest of the project tends to take care of itself. This guide breaks down how to check each one before you commit to hiring a freelance web developer, an agency and everything in between.

What Should You Look for in a Web Developer?

Before you look at prices or portfolios in detail, run every candidate through this checklist.

Portfolio relevance. Not just "do they have a portfolio" but does it include live sites similar in scope to yours. A developer whose entire portfolio is e-commerce stores may not be the right fit for a simple business website, and vice versa. If nothing in the portfolio resembles what you're planning to build, ask directly how they'd approach something new to them.

Communication style. How they respond to your first message tells you how they'll communicate during the project. Slow, vague, or overly salesy replies before you've paid anything rarely improve once you're a paying client. Pay attention to whether they answer the specific question you asked or just send a generic pitch.

Process and milestones. Ask what happens after you say yes. A developer with a real process will describe distinct stages: discovery, design, development, review, launch. Someone who just says "I'll get started" doesn't have a repeatable process, which usually means you'll be the one keeping the project on track instead of them.

Pricing transparency. A quote should break down what you're paying for, not just hand you a single number. I cover exactly what a complete quote should include in my guide to freelance web developer pricing, but the short version is: if you can't tell what's included, ask before you sign.

Post-launch support. Websites need small fixes after launch, even good ones. Confirm whether a support period is included, what it covers, and what happens once that window ends. Is ongoing maintenance a separate monthly service, or are you on your own?

What Does a Web Developer Actually Do?

A web developer turns a design or a concept into a working website: they build the layout and structure, write the code that makes pages responsive across phones, tablets, and desktops, connect a content management system if you need to edit content yourself, set up technical SEO (meta tags, sitemaps, structured data, page speed), and test everything across browsers and devices before launch.

Depending on the developer, they may also handle the design itself, write or edit copy, source images, and configure your domain and hosting. This varies a lot between developers, so it's worth confirming upfront exactly which of these tasks are included in your project versus handled separately.

Should You Look at Freelancers, Agencies, or Both?

Part of knowing what to look for is knowing where to look. Freelancers and agencies solve different problems, and matching the wrong one to your project is a common reason hires don't work out.

A freelancer is usually the better fit if your project is a standard website (anywhere from a single landing page to a 10-page business site) and you want direct access to the person actually building it. You get one point of contact, faster turnaround since there's no internal handoff between departments, and typically a lower price because there's no agency overhead to cover.

An agency makes more sense once your needs go beyond a single website: ongoing work across branding, marketing, and development, enterprise-scale complexity, compliance requirements, or a need for a team available during standard business hours with formal documentation and SLAs.

For most small businesses and startups evaluating candidates today, the checklist in this guide applies equally to both. The difference is mainly in scale and who you're actually talking to day-to-day. A freelancer with a strong portfolio and a clear process can deliver agency-quality results for a fraction of the overhead; the important part is verifying that process actually exists rather than assuming it based on price alone.

How Do You Review a Web Developer's Portfolio?

A portfolio link is not proof of quality on its own. Here's how to actually evaluate one.

Visit the live sites, not just screenshots. Screenshots hide slow load times, broken mobile layouts, and outdated content. Click through to the actual URLs and use the site the way a real visitor would. My Advisia case study is a good example of what a portfolio-quality project should demonstrate: a clear before-and-after, a specific problem solved, and a live, working result you can visit today.

Check mobile responsiveness. Resize your browser window or open the site on your phone. A site that looks great on desktop but breaks on mobile is a portfolio red flag, since most traffic on small business sites is mobile.

Look for variety with a consistent quality bar. You want to see different layouts and industries handled well, not the same template reused with different logos. Google's own responsive design guidelines are a useful reference if you want to check whether a portfolio site actually follows modern layout and accessibility fundamentals rather than just looking good in a screenshot.

Match industry or scale, not exact niche. You don't need a developer who has built ten sites in your exact industry. You need one who has handled projects of similar complexity and size to what you're planning.

Ask for a client contact or testimonial, not just quotes on the page. Testimonials on a portfolio site are easy to write yourself. If a project claims a specific result, like more bookings, faster load times, or more leads, ask whether that's something the client could confirm directly.

What Questions Should You Ask Before Hiring a Web Developer?

The right questions reveal more about a developer than their portfolio does. Ask these before you sign anything:

"What's your process from start to finish?" A clear, staged answer signals experience. A vague answer signals you'll be figuring out the process together, mid-project.

"Who owns the code and domain after launch?" You should own both outright. If a developer hosts your site on a proprietary platform you can't leave, that's a dependency you want to know about upfront.

"Is SEO setup included?" Basic SEO (meta tags, sitemap, structured data, page speed) should be standard, not an upsell. If it's not included, ask why.

"What's your revision policy?" Know how many rounds of feedback are included before extra revisions cost more.

"What happens if the project stalls or timelines slip?" This tells you how they handle problems, not just how they handle things going smoothly.

"Can I see references or talk to a past client?" A developer confident in their work will have no issue connecting you with someone they've worked with before.

"Do you offer maintenance after the support period ends?" Websites need occasional updates, like security patches, content changes, and small fixes, long after launch. Knowing whether that's a service they offer, or something you'll need to find elsewhere, affects your total cost of ownership.

How Can You Tell a Web Developer Is Reliable?

Reliability shows up in small details before the contract is even signed.

They respond promptly and specifically. Not instantly, but within a reasonable window, and with answers that address what you actually asked rather than a generic sales pitch.

Their quote is itemized. A reliable developer breaks pricing into design, development, SEO setup, and what's excluded, rather than a single flat number with no explanation. I go through what a complete, professional quote looks like in detail in my freelance web developer cost guide. It's one of the fastest ways to separate a serious developer from someone guessing at a number.

They put terms in writing. Even a short written agreement covering scope, timeline, and payment terms is a good sign. No paperwork at all, for any project size, is not.

They can point to real, current clients. Live sites you can visit and, ideally, a name you could reach out to if you wanted a second opinion.

What Should You Expect During the Project?

Once you've hired someone, a well-run project follows a predictable shape.

A design review stage before development starts. You should see mockups or wireframes and have a chance to request changes before any code is written, not after.

Regular check-ins. Even a short weekly update is enough for most small projects. You shouldn't go two weeks without hearing anything.

A realistic timeline. Simple one-page sites typically take 3 to 7 days, standard business websites take 1 to 3 weeks, and more complex sites take longer. If your content isn't ready yet, that adds time on top of the build itself.

A defined "done." Launch should come with a short list of what was delivered and a stated support window, typically around 30 days, for fixing anything that comes up after go-live.

A clear communication channel. Whether it's email, a shared doc, or a project management tool, you should know exactly where to send feedback and how quickly to expect a response, instead of guessing which message thread is the current one.

Red Flags to Watch For When Hiring a Web Developer

A few warning signs are worth walking away from, regardless of how good the portfolio looks. None of these are automatically disqualifying on their own, but two or more together is a strong signal to keep looking.

• No live sites in the portfolio. Only screenshots, mockups, or projects you can't actually visit. If a developer can't point you to a single site currently online, treat that as a serious gap, not an oversight.
• Prices that are dramatically below market. A custom site for under $250 usually means templates, no SEO setup, or corners cut somewhere you won't see until later, often after launch when it's expensive to fix.
• No written agreement offered, or reluctance to put scope and payment terms in writing. Verbal promises are not enforceable if the project goes sideways.
• Vague or evasive answers about code and domain ownership after launch. This is one of the most common ways businesses get locked into a developer they no longer want to work with.
• Pressure to decide immediately, especially paired with a "limited time" discount. A legitimate developer with a healthy pipeline doesn't need to pressure you into same-day decisions.
• No mention of responsive design, SEO, or basic web standards anywhere in the conversation or the quote. These should be assumed and included, not treated as optional upsells. Google's own guidance on web accessibility fundamentals is a good baseline for what a modern site should account for by default.

Ready to Talk to a Developer Who Checks These Boxes?

Vetting a web developer against this checklist takes maybe twenty minutes, and it's twenty minutes that can save you from a redesign six months from now. Most of the developers who fail this checklist aren't acting maliciously. They're simply inexperienced, disorganized, or stretched across too many clients to give your project the attention it needs. The checklist exists to catch that before you've paid a deposit, not after.
