Complete Website Development Process From Planning to Launch
The website development process has six stages: discovery and strategy, information architecture and UX, visual design, front-end and back-end development, testing, and launch with ongoing maintenance. A simple site can move through them in a few weeks. A complex online store or custom web app can take six months or more.
This guide explains each stage, what you should receive, and how to keep the project on track.
What are the six stages of the website development process?
| Stage | Main goal | Key deliverables |
|---|---|---|
| 1. Discovery | Agree goals, audience and scope | Brief, sitemap, project plan |
| 2. UX and structure | Plan pages and user journeys | Wireframes, content plan |
| 3. Visual design | Create the look and feel | Page designs, style guide, prototype |
| 4. Development | Build the working site | Front end, back end, CMS, integrations |
| 5. Testing | Find and fix problems | Test report, fixed issues |
| 6. Launch and care | Go live and stay healthy | Live site, training, support plan |
Stage 1: Discovery and strategy
The website development process always starts with questions. What should the site achieve? Who will use it? What do competitors do well? The team then turns the answers into a brief and a sitemap.
This stage also sets the budget and timeline. So spend time here. A clear brief prevents costly changes later.
Stage 2: Information architecture and UX
Next, the team plans how pages connect and how people move through the site. Wireframes show the layout of each page type without colour or images. As a result, you can agree on structure before any design work begins.
This is also the right time to plan content. Decide who writes each page and when it is due.
Stage 3: Visual design
After that, designers add brand colours, type, images and spacing. Usually they design the home page first, then the other templates. You review and approve each one.
Good designs also account for accessibility. For example, text must contrast well with its background. The W3C explains these rules in its WCAG guidelines.
Stage 4: Front-end and back-end development
Then developers turn the designs into a working site. The front end covers what runs in the browser. Meanwhile, the back end covers the server, database, CMS, payments and integrations.
Most teams build on a test server first. That way, you can click through the site while it is being built. Read more in our frontend and backend development guides.
Stage 5: Testing and quality checks
Before launch, the team tests everything, because small faults cost more once the site is live. That includes forms, links, speed, mobile layouts, browsers, security and SEO basics. In addition, someone should test the site with a keyboard only, to check accessibility.
Speed matters for search and for sales. Google explains its speed signals in its Core Web Vitals documentation.
Stage 6: Launch and maintenance
Launch day moves the site to the live server. The team then sets up redirects from old URLs, submits the sitemap and checks analytics. After that, regular maintenance keeps the site secure and fast.
Website launch checklist
- redirects from old URLs are in place;
- HTTPS works on every page;
- titles, descriptions and schema are set;
- the sitemap is submitted to Google Search Console;
- analytics and conversion tracking record visits;
- backups and uptime checks run.
For ongoing care, see our website maintenance guide.
How long does a website development timeline take?
The length of the website development process depends on scope and on how fast feedback comes back. A small brochure site may take two to six weeks. A larger business site may take two to three months. Meanwhile, complex ecommerce or custom apps often take six months or more.
The biggest cause of delay is usually content, not code. Therefore, start writing pages during the design stage.
How do you manage a website project well?
- Name one decision maker on your side.
- Agree sign-off points for each stage.
- Keep feedback in one place, such as a shared board.
- Control changes by writing down extra requests and their cost.
Common mistakes in the process
- Skipping discovery to "save time".
- Leaving content until the end.
- Testing only on one browser or device.
- Launching without redirects from old URLs.
