How long does it take to build a website

When you ask an agency how long does it take to build a website, the standard answer is that it depends. That answer is frustrating, but it is accurate. A simple five page brochure site takes a few weeks, while a complex web application with custom user portals takes several months.

Most projects stall not because of coding speed, but because of decisions, content, and feedback loops. If you want a realistic timeline, you need to look at what actually happens during each phase of design and development.

Here is a breakdown of the real timeline for a professional marketing website or web app, and why certain stages take the time they do.

Discovery and planning take the first week

Before a single pixel is moved or a line of code is written, you need a clear specification. This phase defines the site architecture, the primary user flows, and the technical stack.

If you hire a developer who starts building immediately without a plan, you will waste time later fixing structural mistakes. Discovery usually takes one week for a standard marketing site. Larger web applications might require two or three weeks of scoping to map out databases and third party integrations.

Design and content creation take the longest

The most common bottleneck in web development is content. Developers cannot build pages if they do not know what the pages need to say.

Design happens in parallel with content creation. You review wireframes first, then high fidelity visuals. Expect this phase to take two to four weeks.

If your team struggles to write copy or sign off on visual direction, this is where projects slip by months. You must treat content writing as a priority from day one.

Development and technical SEO happen together

Once the designs are approved, building begins. This is where I code the front end, connect the content management system, and set up any required n8n automations.

For a standard Webflow or custom marketing site, development takes two to three weeks. Web apps take longer depending on the feature set.

During this phase, I also handle technical SEO. That means structuring headings correctly, setting up proper metadata, optimising image sizes, and ensuring fast load times. Waiting until the end to think about search engine optimisation is a mistake. It must be built into the code from the start.

Testing and review require strict attention to detail

When the site is built on a staging server, you need to test it thoroughly. You should check it on different mobile devices, test every contact form, and ensure links point to the right places.

This review phase usually takes one week. You will find small adjustments that need fixing, and your developer will make them. I review every line of code myself before launch to catch issues that automated tools miss.

Launch day is straightforward if preparation is thorough

The final step is pointing your domain to the new server or hosting provider, updating DNS records, and submitting the sitemap to search engines.

A standard launch takes a few hours. If the migration plan is sound, the transition is invisible to your visitors. You own your accounts, your domain, and your code from this moment forward.

Total timelines you can actually plan around

For a standard marketing website of ten to twenty pages, expect the entire process to take six to eight weeks from start to finish. A simple five page site can sometimes be done in four weeks if content is ready on day one.

Web applications and complex sites with custom databases take three to six months. If an agency promises a complex custom build in two weeks, they are usually using rigid templates or cutting corners on testing and technical SEO. Plan for a realistic timeline, and you will get a site that performs well and lasts for years.
