Web design process: complete method for a converting site

Web design follows a precise method. Skipping a step produces a pretty but non-converting site, or vice versa. This guide details the 6 design stages, what happens at each, who validates them, and the traps to avoid at every phase.

The 6 stages of web design

Brief and strategy: who, what, for whom, measurable goals.
Information architecture: sitemap, pages, navigation.
Wireframes: page structure in grayscale (no design).
Graphic mockup: final design applied.
Interactive prototype: clickable navigation before development.
Development, testing, launch.

Step 1: Strategic brief

This is the most neglected and most decisive step. Answers to formalize:

What's the #1 goal of the site? (generate leads, sell online, inform).
Who is the target visitor? (persona with needs, frictions, jargon).
Who are the direct competitors? How do you differentiate?
Which indicators will measure success? (forms/month, sales, traffic).
What's the total budget (creation + recurring + marketing)?

Without these answers, the designer works blind. Count 1–3 hours of brief meeting with a good provider.

Step 2: Information architecture

List of pages, hierarchy, primary and secondary navigation. Output: a visual sitemap (tree) showing all pages and their links. For a standard SMB: 7–12 pages. Beyond 20, you dilute the message.

Define main navigation (5–7 entries max).
Choose between vertical vs horizontal view (mobile-first dictates).
Think about the footer (often forgotten but visited by 30% of users).
Define breadcrumb if needed.

Step 3: Wireframes

Grayscale mockups, without final colors or definitive images. The goal: validate the structure (where the title is, where the CTA is, how info is organized) without being distracted by aesthetics.

Wireframes for 3–5 key pages minimum (home, service, contact).
Tools used: Figma, Sketch, Adobe XD.
Client validation at this stage avoids 80% of back-and-forth in the design phase.

Step 4: Graphic mockup

Final design applied: colors, fonts, photos, illustrations, animations. Output: static mockups for each page type.

Coherent style guide (palette, fonts, spacing, button style).
Tests on 3 screen sizes (mobile, tablet, desktop) minimum.
2–3 rounds of revision are healthy. Beyond that, signal of poorly scoped brief.

Step 5: Interactive prototype

Often skipped — that's a mistake. The prototype lets you click elements as in a real site, without yet having coded. Detects flow problems before development (costly to fix later).

Step 6: Development, testing, launch

HTML/CSS/JS development or WordPress/Shopify integration depending on platform.
Tests: speed, mobile, forms, accessibility, basic SEO.
Migration from old site with 301 redirects to preserve SEO.
Progressive launch (sometimes in "hidden" mode for 48h testing).

Common mistakes at each stage

Sloppy brief: "we'll see along the way" = guaranteed disaster.
Skipped wireframes: go straight to design, then redo everything.
Too many pages from the start — better to launch 7 excellent pages than 20 mediocre ones.
No validation at each stage — huge costs in late correction.
Launch without real tests on 3 browsers and 3 screen sizes.

What does web design cost?

Small site (5 pages): $1,500–$3,000 design included.
Medium site (10–15 pages): $3,000–$6,000.
Large site (e-commerce, custom): $6,000–$15,000 and up.

The design phase (brief + wireframes + mockup) typically represents 30–40% of the total project budget.

Frequently asked questions

How long does the design phase take?

2–4 weeks for a standard site, from brief to validated mockup. More if many back-and-forths or unclear brief at start.

Can you skip the wireframes phase?

Technically yes, but not recommended. Skipping wireframes = 30–50% more back-and-forth in the design phase. It's longer and more expensive overall.

How many pages should be mocked up?

5–8 key pages (home, typical service, contact, about, article page, cart if e-commerce, legal). Other pages draw from the created templates.

Does the designer also develop?

Not necessarily. Often designer ≠ developer. A good agency separates the two roles. A freelancer can do both but rarely as well on both sides.
