Checklist and Roadmap: How to Build a Website from Scratch, Step by Step
The six steps, in order, to launch a website without forgetting anything: goal, domain, design, development, technical SEO and launch.
By Keyner Trillos· Updated
In short
- Building a website without a roadmap leads to delays, unexpected costs and slow sites. There are six steps worth following in order.
- 1) Goal and sitemap, 2) domain and DNS, 3) design, 4) development, 5) technical SEO and structured data, 6) launch and testing.
- A custom corporate site takes 2 to 4 weeks; a landing page, 7 to 12 days.
Launching a website without a clear plan is a recipe for last-minute changes, cost overruns and a site nobody finds. This roadmap puts the process into six steps so nothing slips through.
The 6 steps to build a website from scratch
Step 1: goal and content architecture
Before designing, define what your site is for: generating leads on WhatsApp? Selling products with a cart? Showing corporate authority? Then draw the sitemap: which pages there will be and how they connect.
Step 2: domain and DNS
Pick a short, memorable name. In Colombia, .com and .co are the most used extensions to rank locally and internationally. We explain it in what a domain is and how to choose one.
Step 3: interface design
Design for mobile first, with good contrast and visible calls to action. A unique design made for your brand sets you apart from template-built sites.
Step 4: development
The code determines speed, security and how easy it will be to grow. A custom site, without heavy builders, can load its main content in under a second.
Step 5: technical SEO and structured data
- Unique titles and descriptions for every page.
- H1 to H3 headings in a logical order.
- Structured data (schema.org).
- A sitemap.xml so Google discovers your pages.
Go deeper in why SEO is planned from the architecture.
Step 6: launch and testing
Publish on global servers with an SSL certificate, test on different devices, measure speed and monitor uptime.
