Technical SEO: Audits, Indexing & Core Web Vitals

Technical SEO

Even the best content achieves nothing if Google cannot cleanly crawl and index it.

Technical SEO That Search Engines Can Trust

We conduct a thorough technical SEO audit and fix issues that systematically undermine rankings: page speed, crawl errors, duplicate content, missing structured data and indexing problems. Because we also do web development, we implement fixes directly in code – no long ticket queues.

The essentials of Technical SEO

  • Technical SEO audit: find and fix crawl errors, load times, duplicate content and indexing issues.
  • Fixes directly in code, because we also build – no long ticket queues.
  • Better Core Web Vitals (LCP, CLS, INP) via images, server and caching – a direct ranking factor.
  • Canonicals, clean redirects and controlled indexing concentrate ranking value on the right URLs.
  • Structured data as the basis for rich snippets and AI citability.
Technical foundation for top rankings

Why technical SEO is the foundation

  1. Visibility & Rankings

    Goal: win relevant queries with indexed, fast-loading pages

  2. Backlinks & Authority

    External links consolidate ranking power – only when canonicals are clear

  3. Content & Relevance

    High-quality content can rank – once Google cleanly understands it

  4. Indexing & Crawling

    Robots.txt, sitemaps and canonical strategy control what gets indexed

  5. Technical Foundation

    Page speed, Core Web Vitals, structured data, zero crawl errors

What to know about Technical SEO

  1. Technical SEO is the foundation

    High-quality content and strong backlinks deliver no full effect if technical errors prevent Google from crawling and indexing correctly. Technical SEO is not the most exciting part, but it is the prerequisite for everything else.

  2. Core Web Vitals count

    Google uses Core Web Vitals (LCP, CLS, INP) as a direct ranking signal within the Page Experience update. Pages with poor scores lose ground to technically clean pages even when content quality is comparable.

  3. Duplicate content dilutes rankings

    When multiple URLs have nearly identical content – through filter paths, HTTP/HTTPS duplicates or missing canonicals – Google splits ranking value across all variants instead of consolidating it.

Discuss your project

  • Technical Audit

    We crawl your entire website and identify all technical errors with a direct ranking impact: broken links, redirect chains, missing or duplicate meta tags, canonical errors, slow Core Web Vitals and crawling blocks in robots.txt or HTTP headers.

  • Core Web Vitals and Page Speed

    Google uses Core Web Vitals as a direct ranking factor. We analyze LCP, CLS and INP on your most important pages and fix the underlying causes: image optimization, render-blocking resources, server response times and caching configuration.

  • Indexing Control

    Not every URL should be indexed – duplicate content, filter pages and pagination pages can dilute rankings. We review your indexing signals (canonical, noindex, XML sitemap) and ensure Google has exactly the right pages in its index.

  • Structured Data

    Schema markup helps Google understand the content of a page – and is the basis for rich snippets and AI citability. We implement structured data for relevant content types: Article, FAQ, Product, Organization, BreadcrumbList and LocalBusiness.

What matters for Technical SEO

Technical SEO is the foundation everything else rests on, and precisely for that reason it's the thing most easily overlooked. High-quality content and strong backlinks can't reach their full effect if Google can't crawl and index the page cleanly. The work therefore starts with a sober question: does the search engine even find, understand, and index your content the way you intend.

Core Web Vitals aren't a nice-to-have but a direct ranking factor in the page-experience signal. With otherwise comparable content, slow pages lose to fast ones. The lever rarely lies in a single trick but in consistent work on LCP, CLS, and INP across images, scripts, and layout stability.

Duplicate content is the silent value-destroyer. Filter paths, HTTP and HTTPS variants, or missing canonicals make Google split ranking value across many versions instead of concentrating it on one URL. A clear canonical strategy and clean redirects reconcentrate that power.

What separates technical SEO here from pure consulting is direct implementation in code. Findings that in other setups hang in ticket loops for months can be fixed as soon as they're identified. Speed of execution is itself a quality marker here.

Technical SEO: our approach

From full audit to code-level fix – we close the gap between finding and fixing, without routing through external dev teams.

  1. Technical Audit

    Crawl analysis, GSC review, duplicate content check and log-file analysis expose every blocker

  2. Core Web Vitals

    LCP, CLS and INP are measured and optimized at image, script and layout level

  3. Indexing Control

    Canonical strategy, robots.txt, sitemaps and redirects are cleaned up and consolidated

  4. Structured Data

    Schema.org markup is added so Google can surface content as rich results

  5. Direct Code Implementation

    Findings are fixed straight in the codebase – no ticket queues or handoffs

Because we handle web development in-house, each phase flows directly into the next.

Technical SEO depends on the CMS – as a TYPO3 agency we set up canonicals, hreflang, structured data and redirects directly in the site package.

Frequently asked questions

Your question isn't here?

Ask directly
What does a technical SEO audit involve?
We crawl your website with professional tools, cross-reference results with Google Search Console and Analytics, and produce a prioritized list of issues. Every problem is documented with severity, estimated impact and a concrete recommendation – so it is clear where to start.
Do you fix the errors yourselves or pass them to the developer?
Since we do web development ourselves, we can implement technical fixes directly – without you acting as an intermediary between agency and developer. For systems we do not host, we work with your developer and provide clear specifications.
How often should you run a technical SEO audit?
Once is good – continuously is better. Actively developed websites accumulate new technical errors with every release. We recommend at least one full audit per year plus automated monitoring for critical issues like broken crawling signals.
