Technical SEO: the foundation without which nothing ranks.

Core Web Vitals, Schema markup, crawling, indexing. We use real GSC data and Screaming Frog to analyze your site—not tool-generated scores.

No matter how good your content is: if Google can’t crawl and index your pages properly, no one will see them. Technical SEO is the discipline that ensures search engines can read, understand, and index your website without errors. No rankings without solid technical foundations.

We systematically check your website’s technical foundation—using real crawl data and Google Search Console, not a score from some random online tool. If something is broken, we’ll find it. And we’ll tell you what actually impacts your rankings and what’s just cosmetic.

Project Example: Saving Core Web Vitals

TYPO3 website · 180 pages
, 18-hour sprint
(anonymized)

Background

  • B2B service provider with a TYPO3 website
  • GSC: 65% of URLs with poor Core Web Vitals (May 2025)
  • LCP sometimes > 5 seconds
  • CLS at 0.35 (target < 0.1)
  • 12 main keywords dropped by an average of 6 positions in 8 weeks

What we did

  • GSC Field Data Analysis: LCP Issues from Hero Image (Unoptimized)

  • Critical CSS extracted, JavaScript set to defer
  • CLS fix: explicit width/height for all iframes/videos
  • Preload hints for fonts and hero image
  • Schema markup for Organization + Service + FAQPage implemented

FAQ

Frequently Asked Questions About Technical SEO

Ten questions we’re asked regularly — answered straight up, without any marketing jargon.

How much does a technical SEO audit cost?

Standard starting at €864 net (8 hours) for websites with 50–500 pages. Express Audit (3 business days) starting at €1,620. Enterprise Audit (500+ pages) starting at €3,240. All prices are hourly (€108/h). During the initial consultation, we’ll estimate the effort required for your specific website.

How often should you conduct a technical SEO audit?

At least once a year, or after major changes to the website (relaunch, CMS migration, new plugin). In the meantime, we recommend monthly monitoring: regular crawls that automatically detect changes.

What are good Core Web Vitals scores?

Google defines "good" as: LCP under 2.5 seconds, INP under 200 milliseconds, CLS under 0.1. These metrics must be achieved in the 75th percentile of page views—75% of your visitors must experience this level of performance, not just lab tests.

How important is schema markup, really?

Very important; varies depending on the page type. For B2B service providers, Organization, Service, FAQPage, and BreadcrumbList are mandatory. Schema markup will be particularly relevant in 2026 because AI overviews and AI-generated answers (ChatGPT, Gemini, Perplexity) use structured data to identify sources.

Can I handle technical SEO on my own?

The basics, yes: Screaming Frog and Google Search Console are freely available. The challenge isn’t in identifying the issues, but in evaluating them: Which issues actually affect your rankings? Which are cosmetic, and which are critical? That takes experience.

What is PageSpeed optimization, and how is it related to Core Web Vitals?

PageSpeed optimization is the umbrella term for measures taken to improve page load times. Core Web Vitals are the three specific metrics Google uses to measure this quality (LCP, INP, CLS). We bill for PageSpeed sprints on an hourly basis (€108/hour).

What is the difference between crawling and indexing?

Crawling = Google finds and reads your page. Indexing = Google adds the page to its search index. A page can be crawled but not indexed (e.g., if it has a noindex tag or is of poor quality).

Is technical SEO alone enough to achieve good rankings?

No. Technical SEO is the foundation, but without good content and a well-thought-out strategy, even a technically flawless website won’t rank. That’s why technical SEO is always part of our overall strategy. Learn more on our SEO consulting page.

Do you also do server optimization?

We configure the CMS layer (TYPO3, WordPress, Neos) and work closely with your hosting provider. We do not handle pure server administration (PHP tuning, Nginx configuration, CDN setup) ourselves—but we can recommend hosting partners based on our project experience.

My project is in trouble: Core Web Vitals are in the red in GSC, and rankings are plummeting. What should I do now?

This isn't a routine audit case—it's an emergency. We respond within 30 minutes, even at night and on weekends—via Code-Rescue.
