Your website has technical issues that neither you nor your team can see.
Google doesn't crawl the URLs that matter and crawls thousands that shouldn't exist. Pages take 4 seconds to load and you lose sales you didn't know you were losing. Schema is badly implemented or doesn't exist. The migration 8 months ago left hundreds of broken redirects. Each of these issues quietly slows down your organic growth. You won't see an error message in Search Console. You will just see that traffic isn't growing and no one knows why.
What you get from technical SEO done right
- Fast website Google rewards
- Clean and efficient indexing
- Solid foundation to grow
What we cover in the technical SEO of a project
We cover the 6 technical areas that most impact organic performance. The specific scope adjusts to the size of the site, the platform and the criticality of each detected issue.
Core Web Vitals and performance
LCP, INP and CLS measurement with real CrUX data. Diagnosis with Lighthouse and PageSpeed Insights. Prioritized optimization plan for JavaScript, images, fonts and server.
Indexing and crawl budget
Analysis of which URLs Google crawls and indexes. Crawl budget optimization on large sites. Management of canonicals, noindex, robots.txt and sitemap.xml.
Technical architecture and internal linking
URL structure, depth, internal PageRank distribution. Especially critical on ecommerces with thousands of URLs and portals with complex architectures.
Advanced schema markup
Implementation and validation of structured data by content type (Product, Article, FAQ, Organization, BreadcrumbList, Service). Optimization for rich results and for LLMs.
Technical migrations without losses
Platform, domain or URL structure changes without losing positions. Prior audit, redirect map, equivalence validation and post-migration monitoring.
Technical incident resolution
Unexpected traffic drops, Search Console errors, hreflang issues on multilingual sites, duplicate content, 4xx/5xx errors. Diagnosis and recovery plan.

Frequently asked questions about this service
-
We don't sell technical SEO as a standalone service. We deliver it inside the continuous SEO Execution work, where depending on the project we also include on-page optimization, content strategy and everything the site needs to grow. SEO Execution starts from €1,500/month and is adjusted based on project scope. If you only need an initial technical diagnosis without a continuous commitment, we recommend starting with an SEO audit (a one-time project between €3,000 and €6,000).
-
Because standalone technical SEO doesn't produce results. You can have a technically perfect site and still not rank well if the content doesn't answer search intent or if you lack authority. And the other way around: excellent content on a broken technical base does not reach its potential. The levers work together. That is why we integrate technical SEO inside the complete SEO Execution, where it moves alongside the rest.
-
Four issues repeat across most sites that reach SEOCOM: Core Web Vitals out of threshold (especially INP on JavaScript-heavy sites), broken or chained redirects from badly executed migrations, schema badly implemented or missing on important content types, and URLs Google shouldn't crawl that eat crawl budget. All four are solvable, but they require diagnosis before touching anything.
-
Yes. We have 25 years with WordPress, Magento, Shopify, Prestashop, headless setups with Astro/Next.js/Nuxt, custom platforms and many more. The technical methodology is cross-stack even if tools and solutions change. If your site runs on something uncommon, we can also work coordinated with your development team.
-
No. If you have a development team, we work coordinated with them to implement technical changes. If you don't, we execute directly on your CMS or coordinate with your development agency. The implementation part is never a bottleneck in our projects.
-
Depends on the issue. Core Web Vitals improvements show up in CrUX data at 4-6 weeks. Indexing changes can show at 2-3 weeks. Recovery after a poorly executed migration can take 2-3 months. Schema implementation with rich results is usually visible in 4-8 weeks. Continuous monitoring lets us see the impact and adjust.
-
Yes. Core Web Vitals is one of the pillars of modern technical SEO. We work LCP, INP and CLS with real CrUX data, not just simulated Lighthouse scores. We identify bottlenecks in JavaScript, images, fonts and server, and propose an optimization plan prioritized by impact. On projects with serious performance issues, this is the first thing we address.
-
Yes, with specific experience in multilingual projects with complex hreflang structures. Setting up hreflang correctly on large sites with many markets is one of the most recurring and worst-solved technical issues in generalist agencies. We know how to do it right.
