Technical SEO — Audit and Implementation

We improve the health and performance of your website through systematic technical audit and precise implementation. Our focus is on LD+JSON structured data, ARIA tagging and accessibility, as well as server and speed optimization — everything necessary to ensure trouble-free indexing, high visibility and better conversions.

Benefits

Higher visibility

Clean technical foundation → better crawling, better indexing and stable positions.

Faster website

TTFB, Core Web Vitals and caching for instant page loading.

Better accessibility

ARIA roles, semantics and a11y improvements improve UX and indirectly contribute to SEO.

Scope of Work

LD+JSON & structured data

  • Defining suitable schemas (Organization, WebSite, WebPage, BreadcrumbList, Product, FAQPage and others).
  • Combined LD+JSON feed on page and validation against search engine guidelines.
  • Automation of data (dynamic filling, alignment with CMS/database).
  • Control of duplication and consistency for multilingual websites (hreflang + in-JSON references).

ARIA tagging & accessibility

  • Semantic HTML elements, roles and relations (landmarks, navigation, main, complementary).
  • Alternative texts, tags and focus for keyboard navigation.
  • Contrast check, heading hierarchy, skip links and manage modal states.
  • Minimization of hidden/repeated content for screen readers.

Speed: server & environment

  • TTFB & DNS optimization, HTTP/2–HTTP/3, TLS, compression(Gzip/Brotli).
  • Caching (edge/CDN, object/page cache), stale-while-revalidate and correct cache headers.
  • Optimization of images (auto WebP/AVIF, responsive srcset, lazyload) and critical CSS.
  • Optimization of database, PHP/Node runtime, workers/queue and monitoring (APM, logging, SLO/SLI).

Methodologies and best practices

  • Crawling and indexing: robots.txt, XML sitemaps, canonicalization, parameters and noindex rules.
  • Mobile optimization and rendering: mobile-first, hydration/SSR, deferred/async scripts.
  • Core Web Vitals: LCP, CLS, INP — measurement, diagnosis and iterative improvements.
  • URL architecture and internal linking: navigation, breadcrumbs, pagination and faceted navigation.
  • Internationalization: hreflang, regional targeting, consistent metadata and prevention of duplication.
  • Redirects and status codes: 301/302 policy, 4xx/5xx monitoring and soft-404 prevention.
  • Static resources: bundling/treeshaking, HTTP caching, preconnect/prefetch/priorities.
  • Security, affecting SEO: HSTS, CSP, secure cookies and correct canonical/alternate headers.
  • Log analysis: crawl budget, bots, crawling frequency and detection of blocking errors.
  • QA and regression: automated tests, validators, Lighthouse/devtools profiling and release checklist.
