Our Lisbon web development follows a methodology designed for Portuguese market requirements: (1) Strategy and planning (week 1): defining what to build and for whom. Audience analysis: understanding who the website/application serves — Portuguese consumers, international visitors, B2B clients, or a combination. Each audience: different language needs, different design expectations, and different conversion paths. Content strategy: defining the content the website needs — in which languages, targeting which keywords, and serving which user journeys. Portuguese SEO: keyword research in pt-PT (European Portuguese), analysing Portuguese SERP features, and identifying content gaps in the Portuguese market. Technology selection: choosing the right technology stack. Our recommendation for most Lisbon projects: Next.js (React-based framework providing server-side rendering, static generation, and excellent SEO capability), TypeScript (type safety for reliable development), Tailwind CSS (utility-first CSS for consistent, responsive design), and headless CMS (Sanity, Contentful, or Strapi — for content management by non-technical team members, with support for multilingual content). For eCommerce: Shopify (for standard retail — strong Portuguese market support), Medusa (open-source headless eCommerce — for custom requirements), or custom (for unique business models). For web applications: Next.js with appropriate backend — Node.js for JavaScript-native teams, Python (FastAPI/Django) for data-heavy applications. (2) Design (weeks 1-3): creating the visual and interactive experience. UX design: user research-informed design — understanding how Portuguese users interact with websites. Portuguese web behaviour: mobile-first (58% of Portuguese web traffic on mobile — designs must be mobile-native, not responsive adaptations of desktop designs), scroll culture (Portuguese users: comfortable with longer, scrollable pages — more so than Northern European users who tend to prefer concise, above-the-fold content), and visual quality (Portuguese design culture: appreciating warmth, colour, and visual richness — clean and minimalist works, but sterile and cold does not). UI design: high-fidelity mockups for all key pages — desktop and mobile. Design system: reusable components ensuring visual consistency across the site. Portuguese design considerations: typography (Portuguese text tends to be longer than English — layouts must accommodate longer words and sentences without breaking), imagery (authentic Portuguese context — not generic stock photography. Lisbon's distinctive architecture, light, and colours should inform the visual design where appropriate), and colour (Portuguese culture: warm colours resonate — the azulejo blue, the terracotta of Lisbon's rooftops, the warm yellows of the Tram 28 route. These aren't mandated but the cultural colour palette influences what feels natural to Portuguese audiences). Accessibility: WCAG 2.1 AA compliance designed in from the start — colour contrast, keyboard navigation, screen reader compatibility, focus management, and semantic HTML. Not an afterthought or a separate "accessible version" — the primary design is accessible. (3) Development (weeks 2-6): building the website or application. Frontend development: React components built with TypeScript — type-safe, testable, and maintainable. Performance: a primary development concern. Core Web Vitals targets: LCP < 2.5s, CLS < 0.1, INP < 200ms. Portuguese users on mobile: often on 4G connections with higher latency than fibre — performance optimisation particularly important for mobile experience. Image optimisation (Next.js Image component — automatic WebP/AVIF, responsive sizing, lazy loading), code splitting (loading only the JavaScript needed for each page), and font optimisation (preloading, subsetting — particularly important for Portuguese characters: ã, ç, õ, é, ê, ú, etc.). Multilingual implementation: for bilingual/multilingual sites — Next.js internationalisation with route-based language switching (/pt for Portuguese, /en for English). Content: managed in the CMS with language-specific fields — not duplicated pages but structured multilingual content. SEO: separate meta tags, hreflang tags, and sitemaps per language — ensuring Google serves the correct language version to each user. Portuguese payment integration: for eCommerce and payment-enabled sites — Multibanco (via SIBS/eupago/ifthenpay), MB Way (mobile payment API), credit cards (Stripe or local acquirer), and SEPA Direct Debit (for recurring payments). Each payment method: tested with Portuguese banks and payment providers. RGPD implementation: cookie consent management (Cookiebot, CookieYes, or custom — genuinely blocking cookies before consent), privacy policy page (in Portuguese — legally required), contact form data handling (data minimisation, purpose limitation, storage limitation), and user data rights (access, deletion, and portability capability built into the system). Backend development (for web applications): API development, database design, authentication, and business logic. Hosting: Vercel (for Next.js — excellent performance with European edge locations) or AWS eu-west-1 (Ireland) for applications requiring more infrastructure control. Portuguese data considerations: for applications processing sensitive Portuguese data, hosting within the EU ensures RGPD compliance without cross-border data transfer complications. (4) Content and SEO (weeks 3-5): creating and optimising content. Portuguese content creation: written by native European Portuguese speakers — content that sounds natural to Portuguese readers. SEO content: targeting Portuguese keywords identified during strategy, with proper heading structure, internal linking, and semantic HTML. Technical SEO: XML sitemap, robots.txt, structured data (Schema.org — LocalBusiness, Organization, Product, Article as appropriate), canonical tags, and proper crawlability. Portuguese local SEO: Google Business Profile setup and optimisation (for businesses serving local customers), local citations in Portuguese business directories, and NAP (Name, Address, Phone) consistency across the web. (5) Testing and launch (weeks 5-6): ensuring quality before going live. Cross-browser testing: Chrome, Safari, Firefox, and Edge — on desktop and mobile. Portuguese users: 45%+ on mobile Safari (iPhone) — Safari compatibility critical. Performance testing: Lighthouse audits, Core Web Vitals measurement, and real-user monitoring setup. Target: Lighthouse performance score 90+. Accessibility testing: automated (axe DevTools) and manual (keyboard navigation, screen reader testing). RGPD compliance testing: verifying that cookies are blocked before consent, that privacy policy is accurate and accessible, and that data handling meets RGPD requirements. Launch: DNS transition, CDN configuration, and search engine notification (sitemap submission to Google Search Console). Post-launch monitoring: uptime monitoring, error tracking (Sentry), and analytics (GA4 with consent-mode — RGPD compliant).
