How to build a marketing website in 30 days — field guide for 2026

The 30-day marketing website: a field guide

Most marketing websites take 60 to 120 days. We ship in 30. This guide explains how and why.

We work in two-week sprints. We demo weekly. We deploy to a preview site on day 14. We ship on day 30. We stay on for 30 days of support.

The 30-day promise

We promise a fixed quote in 48 hours. We promise a fixed scope in 30 days. We promise a fixed fee.

Week 1: Find and design

We start with a 60-minute find call. We align on goals, audience and success metrics.

We deliver wireframes by day 3. We deliver a full Figma design by day 7. One round of changes is included.

Week 2: Build and CMS

We build on a staging URL. We wire the headless CMS. We set up content models. We set up the design system. For how to choose the right headless CMS for your team, see our headless CMS decision guide — the same content model thinking that goes into a 30-day build goes into our CMS shortlist.

We deploy to a preview URL on day 14. The first 5 pages are working.

Week 3: Build and add-ons

We build the rest of the pages. We add the AI chatbot. We set up stats. We run a speed audit. The AI chatbot in a 30-day build follows the same edge AI-first principles we use for all WebGrow24 products — small models for routine tasks, larger models for complex queries, regional endpoints with caching.

The audit checks Core Web Vitals. It checks JS bundle size. It checks image setup. See the performance budget playbook for our targets.

Week 4: Launch and hand off

We run a final QA pass. We deploy to production. We train your team. We hand off the keys.

We stay on for 30 days of support.

What we skip

We skip templates. We skip junior teams. We skip feature creep. We build on Next.js 16 with proper server rendering — the same technical decisions covered in our Next.js 16 edge runtime lessons that ensure every page ships with clean HTML for search engines.

We use senior engineers. We use a senior designer. We use a senior SEO specialist.

We do not use stock photos. We do not use AI-generated copy without review.

What you get

You get a premium marketing website. It runs on Next.js. It has a headless CMS. It has an AI chatbot. It has analytics and SEO wired in.

You get a 30-day support window. You get a fixed fee. You get a fixed scope.

When 30 days is wrong

When you have 50+ pages, multi-locale needs or complex add-ons, 30 days is wrong.

We tell you on the find call. We do not promise what we cannot deliver.
