Développement de Plateforme d'Annuaire Entreprise

Elasticsearch stores each listing with geo-point fields, which means radius-based queries, geo-distance sorting, and bounding-box filtering all happen in one index rather than across joined tables. Combine that with faceted search on categories, ratings, and verification status, and you're hitting p95 search latency under 120ms across 190K+ documents. We've stress-tested this architecture to 500K listings without needing to change anything structural.

We use Incremental Static Regeneration on Next.js. The top 2,000 pages by traffic get pre-built at deploy time — everything else generates on first request and caches at edge. Each page revalidates on a configurable interval, so new listings show up within minutes rather than after a full rebuild. It's a practical approach that scales to 50,000+ programmatic pages without making your CI pipeline miserable.

We model claims as a finite state machine: `unclaimed → claim_requested → verification_pending → verified → disputed → transferred`. Each state transition triggers automated actions — verification challenges, role grants, admin notifications, audit logs. Supabase Row Level Security enforces that verified owners can only edit their own listings. The whole flow is fully auditable and handles multi-location businesses without special-casing.

Yes. We build custom ETL pipelines for bulk imports that handle geocoding validation, duplicate detection, and category normalization. We've imported 40,000+ listings in a single batch with zero search downtime by running Elasticsearch reindexing in parallel. Your existing data gets cleaned, geocoded, and deduplicated as part of the migration — you're not just dumping raw records into a new system.

Each city-category page gets unique content signals: dynamic listing counts, top-rated business highlights, CMS-managed category descriptions, breadcrumb navigation, and JSON-LD LocalBusiness structured data. Internal linking between related cities and categories builds topical authority across the whole site. Across our directory deployments, we've hit 91,000+ indexed pages with Lighthouse scores above 95.

Enterprise directory platforms run 14-20 weeks across four overlapping phases: data architecture and search, programmatic pages and frontend, claim workflow and admin tools, and data pipeline with launch. Budget ranges from $80,000 to $250,000 depending on listing volume, custom workflow complexity, and integration requirements. All engagements include 90 days of post-launch support.

Off-the-shelf solutions work fine for directories under 20,000 listings. Push past that — especially toward 190K+ — and things start breaking. Search slows to a crawl, page generation chokes on volume, and claim workflows fall apart under concurrent verification requests. Custom architecture gives you full data ownership, sub-200ms search at any scale, and programmatic page generation that actually ranks. At enterprise scale, that difference shows up directly in organic traffic numbers.
