Ask a Web Developer: How to Hire, Vet & Work with Dev Teams

Knowing what to ask a web developer before, during, and after a project can be the difference between a website that drives real business results and one that sits idle, drains budget, and frustrates everyone involved. Business owners across the UK and Ireland regularly commission website builds or redesigns without a clear framework for evaluating the people they hire – and that leads to missed deadlines, poor-quality code, and projects that go over budget.

This guide is designed to give you that framework. Whether you are hiring a developer for the first time, working with a new agency, or troubleshooting an underperforming site, the right questions will help you separate strong candidates from weak ones and set your project up for long-term success. ProfileTree, a Belfast-based web design and digital marketing agency, works with SMEs across Northern Ireland, Ireland, and the UK, and this guide draws on that direct experience.

Evaluating Developer Experience

Before you ask a web developer anything technical, you need to understand their background and whether their experience is relevant to what you actually need. A developer with ten years building complex SaaS platforms is not necessarily the right fit for a small business e-commerce site – and vice versa.

Review Their Portfolio Critically

Ask a web developer to walk you through their portfolio in detail, not just show you a list of links. You want to understand what role they played in each project, what problems they solved, and what platforms or technologies they used. A polished-looking website in a portfolio tells you relatively little on its own. What matters is whether the developer can explain the decisions behind it.

Look for projects that are similar to yours in scope, industry, or technical requirements. If you need a WordPress site with WooCommerce integration, ask whether they have built comparable setups before and whether those sites are still live and performing well.

Ask About CMS and Platform Experience

Content management systems like WordPress, Shopify, and Wix are used across the vast majority of SME websites. When you ask a web developer about their platform expertise, you are really asking whether they can build a site you can actually manage after the project ends. A developer who hands over a bespoke custom-coded system with no CMS may produce something technically impressive but leave you entirely dependent on them for every small change. Choosing a team with a strong track record in professional website design reduces this risk considerably.

Ask a web developer which platforms they specialise in, whether they build from themes or from scratch, and what their reasoning is for recommending one platform over another for your specific use case. A good developer will be able to justify their recommendation clearly rather than defaulting to whatever they find easiest to work with.

Check References and Live Sites

Ask a web developer for references from past clients, not just testimonials on their website. Speaking directly with a previous client gives you a much clearer picture of how the developer communicates, whether they deliver on time, and how they handle problems when they arise. Ask the reference whether they would hire the developer again – that single question tends to produce the most honest answer.

Where possible, visit live sites the developer has built and test them yourself. Check loading speed, mobile responsiveness, and whether the contact forms and other interactive elements actually work. A site that looks good on a screenshot may perform poorly in practice. ProfileTree’s user-focused web design approach means every project is tested thoroughly before handover, so clients can see real performance rather than just a polished preview.

Questions on Process and Communication

How a web development project is managed matters almost as much as the technical quality of the output. Poor communication, unclear timelines, and a lack of reporting are among the most common reasons web projects fail or drag on far beyond their original scope. When you ask a web developer about their process, you are assessing whether they have a structured approach or are making it up as they go.

Define Communication Expectations Early

Ask a web developer how frequently they will provide progress updates and through which channels. Some developers send weekly written reports; others prefer regular video calls; some use project management tools like Asana or Trello to give clients a live view of progress. There is no single right approach, but you need to know what to expect so you are not left chasing updates.

Find out who your main point of contact will be throughout the project. On larger agency teams, the person who sells you the project may not be the person who builds it. Knowing who is accountable for your work is a basic but important piece of information.

Milestones and Deadlines

Ask a web developer how they structure project timelines and what milestones they use to track progress. A well-managed project should have clear checkpoints – wireframe sign-off, design approval, development completion, testing phase, and launch – so that both sides know where the project stands at any given point.

Ask what happens if a milestone slips. Delays happen on almost every project, and a developer who has a clear plan for managing them is much easier to work with than one who simply goes quiet. You should also ask what your responsibilities are within the timeline – if you take two weeks to provide content or feedback, does that push the launch date back?

Scope Creep and Change Requests

One of the most financially significant things to ask a web developer is how they handle changes to the original brief. Scope creep – where additional requirements are added after the project has started – is one of the main reasons web projects go over budget.

A professional developer will have a clear process for logging change requests, assessing their impact on the timeline and budget, and getting written approval before proceeding. If a developer seems unconcerned about scope changes or happy to absorb them without discussion, that should prompt further questions about how the project is being costed. Teams that specialise in custom website builds will document scope boundaries clearly from the outset, making it much easier to manage change requests fairly.

“Business owners often underestimate the importance of the process side of web development. The quality of a website is heavily influenced by how clearly the brief was defined at the start and how well both parties communicated throughout. That groundwork is not glamorous, but it determines whether the project succeeds,” says Ciaran Connolly, founder of ProfileTree.

Technical Areas to Cover

You do not need to be a developer yourself to ask a web developer the right technical questions. What you need is a set of topics that reveal whether the developer is thinking about your site from a business perspective, not just a coding one. The questions below are designed to be asked by non-technical business owners and still generate useful, revealing answers.

SEO and Search Visibility

A website that no one can find is not doing its job. Ask a web developer what they do to make sure the site is built with search engine optimisation in mind from the outset. This includes things like clean URL structures, fast page loading times, mobile-first design, proper heading hierarchy, and the ability to add and edit meta titles and descriptions without developer involvement.

Agencies that specialise in website development services will typically build SEO considerations into the development process rather than treating them as an afterthought. If a developer tells you that SEO is a separate concern to be handled after launch, that is a sign that the site may be built in a way that actively makes search optimisation harder.

You should also ask about Core Web Vitals – the set of Google performance metrics that affect search rankings. A developer who can explain Largest Contentful Paint, Cumulative Layout Shift, and First Input Delay in plain terms is demonstrating a level of technical awareness that will benefit your site’s long-term visibility. Working with a team that provides dedicated search engine optimisation alongside development means these technical signals are tracked and improved over time, not just considered at build stage.

Connecting your web development project to a broader digital strategy support plan is also worth raising with any developer you are considering. A site built without a clear marketing purpose will struggle to generate leads regardless of how well it is coded.

Performance and Mobile Optimisation

Ask a web developer how they test for page speed and what their target loading times are. Most users will leave a page that takes more than three seconds to load, so performance is not an optional extra. Ask which tools they use – Google PageSpeed Insights, GTmetrix, and Lighthouse are all standard – and whether they can show you performance scores from comparable sites they have built. Businesses that use a professional website hosting and management service tend to see more consistent performance over time, as the hosting environment is optimised for the platform being used.

Mobile optimisation goes beyond making a site look acceptable on a phone screen. Ask whether the site is built with a mobile-first approach, meaning the design and functionality is conceived for mobile devices before scaling up to desktop. This approach tends to produce better results across all device types.

Security and Data Protection

For any business handling customer data, security is a serious concern. Ask a web developer what they do to protect the site from common vulnerabilities, how they handle software updates and security patches, and what the process is if the site is compromised.

In the UK and Ireland, GDPR compliance is a legal requirement for sites that collect personal data. Ask whether the developer has experience building sites that meet these requirements, including cookie consent management, privacy policy integration, and proper data handling procedures. The UK Information Commissioner’s Office publishes clear guidance on what organisations must do to meet their obligations under UK GDPR, and a good developer will be familiar with those requirements. A developer who dismisses these concerns or treats them as peripheral is not the right choice for a business-facing website.

Accessibility Standards

Web accessibility – building sites that can be used by people with disabilities – is both a legal and ethical requirement. Ask a web developer whether they build to WCAG 2.2 standards and how they test for accessibility. This includes things like keyboard navigation, screen reader compatibility, sufficient colour contrast, and properly labelled form fields.

Accessibility is increasingly a factor in how Google assesses page quality, so it is also an SEO consideration as well as a compliance one. A developer who integrates accessibility into the build process from the start will save you significant remediation work later. If your internal team needs to understand these requirements more deeply, ProfileTree’s digital training programmes cover web accessibility standards alongside broader digital skills development.

AI Integration and Modern Development Practices

It is worth asking a web developer how they use AI tools in their workflow. Many developers now use AI-assisted coding tools to speed up production, which can be a genuine productivity benefit – but it also raises questions about code quality, security, and whether the output has been properly reviewed.

Ask whether any AI-generated code is tested and audited before it goes into your project. A developer who uses these tools responsibly will be open about it and able to explain their quality control process. ProfileTree’s AI marketing services help businesses understand how AI tools can work alongside existing systems rather than replacing careful human oversight.

You should also ask about the tech stack being recommended and why. The rise of headless CMS architectures, where the content management layer is separated from the front-end delivery, has created genuine performance and scalability benefits for the right type of project. Ask whether this approach is appropriate for your needs, what the maintenance implications are, and whether your team will be able to manage content without developer involvement on a day-to-day basis. If customer interaction is a priority, it is also worth asking whether the developer has experience integrating AI chatbot development into web platforms, as this is an increasingly common requirement for business websites across the UK and Ireland.

Cost, Budget and Post-Launch Support

Understanding what you are paying for – and what happens after the site goes live – is the part of the conversation that business owners most often skip past. The launch is not the end of the project; it is the start of the relationship with the site itself. When you ask a web developer about costs and ongoing support, you are making sure you have a clear picture of the total investment required.

Understanding Pricing Structures

Ask a web developer for a detailed breakdown of what is included in their quote, not just a total figure. You want to know what is covered, what will be charged extra, and where the boundaries of the project scope sit. A fixed-price quote for a clearly defined scope gives you cost certainty; a time-and-materials arrangement gives you flexibility but requires closer budget monitoring.

Ask specifically about hosting, domain management, SSL certificates, and any third-party plugin or software licences that the site will depend on. These ongoing costs are frequently overlooked when comparing quotes and can add up considerably over a twelve-month period. It is also worth asking whether the developer has any experience building sites that are set up to support wider digital marketing activity, including social media marketing integrations and lead capture functionality.

Total Cost of Ownership

Ask a web developer what the realistic total cost of running the site will be over the first two years, not just the build cost. This should include hosting, ongoing maintenance, security updates, content changes, and any platform or plugin subscription fees.

A developer who can give you a clear answer to this question is demonstrating that they understand websites as business assets rather than one-off deliverables. A realistic understanding of the total cost of ownership will also help you avoid the common situation where a low build quote is followed by unexpectedly high ongoing costs. Some agencies bundle additional digital services – such as video marketing services or content production – within a broader retainer, which can represent better value than commissioning each element separately.

Post-Launch Support and Maintenance

Ask a web developer what post-launch support they provide and on what terms. Some developers include a period of free support after launch to cover any bugs or issues that arise during the initial live period; others charge from day one. Find out what a typical support request costs, how quickly they respond, and whether they have a formal service level agreement.

Ask what happens if you want to change developers in the future. You should have full ownership of your website files, domain, and hosting account. Ask for this to be confirmed in writing. Find out whether the code is documented, whether there is a Git repository you can access, and whether another developer could pick up the project without starting from scratch.

Ongoing maintenance should include regular software updates, security monitoring, and periodic performance reviews. A site that is not maintained will degrade over time – plugins become outdated, security vulnerabilities emerge, and performance metrics slip. Ask a web developer to outline a maintenance schedule and what that involves in practical terms. ProfileTree provides managed WordPress hosting as part of its ongoing support offering, which covers security patching, uptime monitoring, and regular backups as standard. Pairing this with professional SEO support means your site’s technical health and search visibility are maintained together rather than managed in isolation.

Asking the Right Questions at the Right Stage

Knowing when to ask a web developer specific questions is as important as knowing what to ask. Some questions are most useful at the initial consultation stage, before you have committed to anyone. Others become relevant once a project is underway. And some – particularly around ownership, support, and exit arrangements – are best asked before you sign any contract.

The most important principle is to get answers in writing. A verbal agreement about what is included in a project scope carries no weight if a dispute arises. Ask a web developer to confirm all key decisions, scope boundaries, and cost estimates in writing before work begins. This protects both parties and reduces the risk of misunderstandings that are expensive to resolve. If you are unsure how your website fits into your wider marketing goals, ProfileTree’s strategic digital planning service can help you define those objectives before a single line of code is written.
