Our Lisbon headless CMS development follows a methodology designed for content-driven businesses: (1) Content strategy and CMS selection (weeks 1-2): designing before building. Content audit: cataloguing existing content — content types, volumes, languages, and update frequency. Portuguese content audit: assessing multilingual content (how many languages? How is translation managed? What's the content overlap between languages?). The audit: revealing the actual content management challenge — often larger and more complex than initially estimated. Content model design: defining the content structure — content types, fields, relationships, and validation rules. Structured content: designing content as structured data rather than free-form HTML. Example: a "Hotel Room" content type with fields for name (multilingual), description (multilingual, rich text), amenities (relationship to amenity content type), images (media), price range, and room size. The structure: enabling content reuse across channels and consistent rendering. CMS selection: choosing the right headless CMS platform. Contentful (our default recommendation for most Lisbon businesses — excellent content modelling, strong API, good editorial experience, and robust multilingual support. Pricing: based on content entries and users — suitable for small to enterprise), Strapi (open-source headless CMS — self-hosted, customisable, and cost-effective. Best for: businesses wanting maximum control and avoiding SaaS vendor lock-in. Hosting: can be deployed on Portuguese/EU infrastructure), Sanity (developer-friendly with real-time collaboration — strong for editorial teams and custom content workflows. Pricing: generous free tier, pay-as-you-grow), or custom headless CMS (built from scratch — only when no existing platform meets the requirements. Rarely necessary — existing platforms covering 95% of use cases). Selection criteria: content model complexity, editorial workflow requirements, multilingual needs, budget, hosting preferences, and integration requirements. (2) CMS setup and content modelling (weeks 2-3): configuring the CMS. Content type creation: implementing the content model in the selected CMS — content types, fields, validations, and relationships. Multilingual configuration: setting up language support — Portuguese (primary), English, and additional languages. Translation workflow: defining how translations are created and managed — manual translation, translation service integration (Lokalise, Phrase), or AI-assisted translation with human review. Editorial workflow: configuring content approval workflows — draft → review → approve → publish. Role-based access: defining who can create, edit, approve, and publish content. For Portuguese organisations: aligning CMS roles with organisational authority. Media management: configuring image and document management — upload, transformation (automatic resizing and format optimisation), and CDN delivery. Portuguese content: handling Portuguese characters (ã, ç, é, ê, ó, ô, ú) correctly in URLs, metadata, and alt text. Preview: enabling content preview — editors seeing how content will look on the website before publishing. Preview environment: showing content changes in the actual frontend design, not a generic CMS preview. (3) Frontend development (weeks 3-6): building the content-consuming application. Technology: Next.js (our default for Lisbon headless CMS projects — React-based, excellent performance, and strong CMS integration ecosystem). Rendering strategy: Static Site Generation (SSG — pre-rendering pages at build time for maximum performance), Incremental Static Regeneration (ISR — regenerating pages in the background when content changes, combining static performance with dynamic content updates), and Server-Side Rendering (SSR — for highly dynamic content that can't be pre-rendered). Most Lisbon sites: ISR as the default — pages served statically with automatic regeneration when CMS content changes. CMS integration: connecting Next.js to the headless CMS API — fetching content at build time (SSG/ISR) or request time (SSR). Content caching: intelligent caching strategy to minimise API calls while ensuring content freshness. Webhook-based revalidation: CMS publishing event triggering Next.js page regeneration — content changes live within seconds of publishing. Portuguese SEO: meta tags, structured data (schema.org), hreflang tags for multilingual pages, sitemap generation, and canonical URLs. Portuguese-specific: hreflang implementation distinguishing pt-PT (European Portuguese) from pt-BR (Brazilian Portuguese) — critical for proper geo-targeting in Google. Performance: targeting Core Web Vitals excellence — LCP under 2.5s, FID under 100ms, CLS under 0.1. Image optimisation: Next.js Image component with CMS media transformation — serving WebP/AVIF in appropriate sizes. Font optimisation: loading Portuguese-character-supporting fonts efficiently. (4) Content migration (weeks 4-5): moving existing content. Migration planning: mapping content from the old CMS (WordPress, Drupal, custom) to the new content model. Content transformation: converting unstructured HTML content into structured content types — extracting metadata, cleaning HTML, and mapping to structured fields. Portuguese content: ensuring proper character encoding throughout migration — no broken characters (ã, ç, é becoming garbled). Media migration: moving images and documents from the old CMS to the new CMS media library — maintaining file names, alt text, and metadata. URL mapping: ensuring all existing URLs continue to work — 301 redirects from old URLs to new URLs. SEO preservation: maintaining search rankings during migration — no broken links, no missing pages, and no SEO metadata loss. (5) Launch and training (weeks 5-7): going live. Content freeze: brief period where content is frozen in the old system and final migration is executed. DNS switch: pointing the domain to the new site — with the old site available as a fallback. Post-launch monitoring: verifying all pages load correctly, all links work, and SEO metrics are maintained. Monitoring: Google Search Console for indexing status, crawl errors, and performance. Training: training content editors on the new CMS — content creation, editing, preview, and publishing. Portuguese training: conducted in Portuguese, with documentation in Portuguese. Training: practical, hands-on — editors creating and publishing real content during training, not watching presentations.
