Fast, indexable, schema-perfect.
Technical SEO built to scale.

You get a full report of roughly 40-60 pages, depending on the project, in which we analyse server logs to see how Google crawls the site, index coverage in GSC, schema markup, Core Web Vitals for the top 50 URLs, redirect chains, the internal linking structure and the hreflang implementation. At the end we deliver a remediation plan prioritised by impact and effort, so it is clear what has to be fixed and in what order.

A technical SEO audit usually takes 5-7 days. Quick wins such as robots.txt, sitemap, schema markup and canonical optimisations can be implemented in 2-3 weeks, while major fixes such as Core Web Vitals, restructures or migrations take roughly 4-8 weeks. After implementation, re-crawling and validating the changes in GSC can take another 30-60 days.

Yes. We guarantee LCP under 2.5s, INP under 200ms and CLS under 0.1 for your top 20 business-critical pages within a maximum of 60 days. We measure performance using CrUX (Chrome User Experience Report) data from real users, not only synthetic Lighthouse tests. If performance drops below the agreed thresholds, we rebuild the affected section free of charge.

The cost of technical SEO services depends on the size and complexity of the site. A one-off technical SEO audit costs between EUR 1,500 and EUR 3,500, while implementing the fixes starts at EUR 3,500-12,000 for sites with up to 1,000 pages and can exceed EUR 25,000 for eCommerce stores with more than 10,000 SKUs. For ongoing technical monitoring and optimisation, the retainer is between EUR 800 and EUR 2,500 per month.

We have technical SEO expertise for WordPress (RankMath, Yoast, Slim SEO), Shopify (theme, Liquid and headless), Magento and custom builds in Next.js, Astro or Nuxt. We implement the optimisations directly in code or work with your development team through pull requests and code reviews.

We prepare a 1:1 URL mapping before launch, implement 301 redirects from the old URLs and check that content and important SEO elements are preserved. For the first 30 days we keep sitemaps for both the old and the new structure and monitor performance daily in GSC and GA4. Across our last 24 migrations, no project lost more than 5% of its traffic.

Schema markup, usually implemented through JSON-LD, helps Google understand what a page's content represents: a product, an article, an event, an organisation and so on. Structured data can make pages eligible for Rich Results in the SERP, such as ratings, prices or product availability, which can contribute to a better CTR. On top of that, schema markup gives search engines and AI systems clearer context about content and entities, which matters for both technical SEO and GEO.

For large eCommerce stores we analyse crawl budget, indexing, site architecture, faceted navigation, filters and URL parameters, pagination, canonicals, out-of-stock products and the internal linking structure. We also optimise Core Web Vitals and implement Product and Offer schema markup, so Google can crawl, understand and index catalogues with tens of thousands of SKUs efficiently.

We can work either way. Danco Vision can implement the technical changes directly when we have access to the site infrastructure and code, or we can collaborate with your development team, handing over the technical requirements and implementation priorities.
