What Technical SEO Actually Fixes — And What It Won't

Your page goes live. Google's crawler arrives in seconds, renders your markup, scores your structure, and decides — before any human sees you — whether your content earns an index slot. Technical SEO is the work you do before that judgment. We audit your crawl, fix your redirect chains, ship schema that tells Google what your pages mean, and tune your Core Web Vitals so your mobile scores deserve your rankings. You get sitemaps that scale to 100K+ URLs, hreflang that reciprocates across your locales, and crawl-budget rules that keep Google's bots focused on your revenue pages — not your faceted-filter dead ends. Done right, your content meets the index on its merit. Done wrong, your best pages stay invisible while sloppier competitors take your rankings.

Dónde fallan los proyectos

Lighthouse scores below 50 on mobile — Google deprioritizes slow pages Rankings drop as Core Web Vitals become a stronger signal; competitors sitting at 90+ are already taking your positions.

Thousands of pages published but only a fraction indexed Content investment wasted — pages that aren't indexed generate zero organic traffic.

No structured data — missing rich results in SERPs Competitors with FAQ, Product, and Review schema dominate the visual real estate and capture higher CTR.

Redirect chains and broken links piling up with every site update Crawl budget gets burned on error pages; link equity bleeds through 3–4 hop redirect chains.

Multilingual site without proper hreflang causing duplicate content flags Google serves the wrong language version to users; content cannibalizes itself across locales.

Faceted navigation and pagination creating millions of low-value URLs Crawl budget gets exhausted on filter combinations; your high-value pages get pushed back in Google's crawl queue.

Nuestro proceso

Crawl & Audit

We run a full Screaming Frog crawl and catalog every broken link, redirect chain, orphan page, missing schema, and Core Web Vitals failure. You get a prioritized spreadsheet with impact and effort scores for each item.

Week 1-2

Architecture Plan

We design the fix strategy: schema types per page template, sitemap structure, hreflang matrix, crawl budget rules, and CWV optimization targets. You approve everything before we write a line of code.

Week 2-3

Implementation

Schema markup in Next.js server components, sitemap generation from Supabase, hreflang with next-intl, CWV fixes through image optimization, dynamic imports, and edge caching. Every change gets validated against Google's tools before it ships.

Week 3-6

Validation & Submission

Rich Results Test on every schema type, Lighthouse audit on key pages, sitemap submission to GSC, hreflang validation, and crawl stats monitoring. Nothing ships until scores hit targets.

Week 6-7

Monitoring & Iteration

30-day post-launch monitoring of index coverage, crawl stats, CWV scores, and rich result appearances. The ongoing tier includes monthly re-audits and continuous optimization.

Preguntas frecuentes

¿Qué incluye una auditoría técnica de SEO?

Un rastreo completo con Screaming Frog que cubre enlaces rotos, cadenas de redirecciones, contenido duplicado, etiquetas meta faltantes, páginas huérfanas, análisis de profundidad de rastreo, evaluación de Core Web Vitals, usabilidad móvil y validación de datos estructurados. El entregable es una lista de correcciones priorizada con impacto de tráfico estimado y esfuerzo de implementación para cada elemento encontrado.

¿Cuánto tiempo tarda una auditoría técnica de SEO?

Una auditoría solo toma 1–2 semanas según el tamaño del sitio. Para un sitio de 10K páginas, espera el rastreo y análisis en la primera semana y la lista de correcciones priorizada en la segunda. Los sitios de más de 50K páginas frecuentemente necesitan pasadas de rastreo adicionales y pueden extenderse hasta 3 semanas.

¿Qué tipos de schema markup implementan?

Implementamos JSON-LD para Organization, LocalBusiness, Article, BlogPosting, Product, Service, FAQPage, HowTo, BreadcrumbList, WebSite, Event, Person y Review. Cada tipo de schema se construye en componentes de servidor del App Router de Next.js y se valida con Google Rich Results Test y Schema Markup Validator antes del despliegue.

¿Pueden mejorar Core Web Vitals en un sitio Next.js existente?

Sí. Hemos llevado sitios de Lighthouse 35 a 94 usando optimización de Next.js Image, importes dinámicos para componentes pesados, subsetting de fuentes con display:swap, SSR, almacenamiento en caché de bordes de Vercel, aplazamiento de scripts de terceros y extracción de rutas críticas CSS. Apuntamos a 90+ en móvil para cada proyecto.

¿Cómo manejan los sitemaps para sitios con 100K+ páginas?

Construimos un índice de sitemap con sitemaps fragmentados de 50K URLs cada uno, generados dinámicamente desde consultas Supabase usando ISR para regeneración. Lo hemos probado a escala — Deluxe Astrology tiene 91K páginas indexadas y Not Another Sunday tiene 137K listados indexados usando esta arquitectura exacta.

¿Soportan sitios multilingües con hreflang?

Sí. Implementamos next-intl con etiquetas hreflang en el head HTML y sitemaps, URLs canónicas conscientes de idioma, datos estructurados específicos del idioma, y compuertas de traducción de dos niveles. Nuestro récord de producción es Deluxe Astrology: 30 idiomas, hreflang en 118 páginas, 41 espacios de nombres y 39 rutas API conscientes de locale.
