Technical SEO: the foundation on which everything else is built
Technical SEO: loading time, mobile use, indexing, clean structure, redirects and structured data, so that search engines can read your site properly.
SEO & GEO
Technical SEO: what is it exactly?
Technical SEO concerns the foundation of a website. A search engine must be able to reach your pages (crawling), understand them (rendering, content) and include them (indexing). Visitors also expect fast loading times and a display that works on every device.
Google assesses user experience, among other things, through metrics such as Largest Contentful Paint (loading time of the main content), Interaction to Next Paint (response time) and Cumulative Layout Shift (stability of the layout). We check these values and improve whatever can be influenced.
Background
Technical SEO: why it matters.
The best content does not help if a page loads slowly, does not work on a phone or is not picked up by search engines at all.
Technical soundness is also a precondition for AI assistants and search systems to read your content reliably.
Overview
Technical SEO: building blocks and variants.
Indexing
Are the right pages included and the wrong ones not? Controlled through noindex and canonical.
Speed
Images, fonts, scripts and servers set up so that pages appear quickly.
Mobile
Responsive design, easy-to-use elements, readable type.
URL structure
Readable, stable addresses, sitemap and clean redirects.
Structured data
Additional information according to schema.org, checked for errors.
Security and privacy
HTTPS and, where possible, no unnecessary third-party services.
Our work
Technical SEO: what we do for you.
Speed
Shorten loading times: images, scripts, caching, delivery.
Mobile use
Check and improve display and operation on smartphones.
Crawling and indexing
Make sure that important pages are found and included.
Structure and addresses
Clean URLs, sitemap, redirects, avoiding duplicates.
Security
HTTPS and a clean configuration.
Structured data
Machine-readable information about your business, services and questions.
Quality
Technical SEO: how to recognise good work.
- All important pages are reachable and indexed
- There is an up-to-date sitemap and a correct robots.txt
- The site loads quickly on mobile too
- There are no broken links and no redirect chains
- Every page has a unique address (canonical)
- Structured data is free of errors
- The site runs exclusively over HTTPS
Costs
Technical SEO: what it costs.
The effort depends on the state of the website and the system used. A cleanly built site needs little, a site that has grown over the years with many legacy issues considerably more.
The calculation behind it: how we price our work.
What determines the price
- Size and age of the website
- System used and plug-ins
- Number of technical problems
- Rebuilds required
- ongoing monitoring
What you can prepare
- Access to the website, server or hosting
- Access to Google Search Console
- A list of known problems
- Contacts for technology and hosting
Pitfalls
Technical SEO: common mistakes.
- Huge, uncompressed images
- Unintentionally blocking pages through robots.txt or noindex
- Many broken links and redirect chains
- Duplicate content under several addresses
Frequently asked questions
Questions about technical SEO.
What are Core Web Vitals?
Google metrics for the loading speed, response time and visual stability of a page. They describe how pleasant a page is to use.
What does indexing mean?
That a page has been taken in by the search engine and can appear in the results.
Do I have to use a different system for this?
Usually not. Many problems can be fixed in the existing system. We only recommend a switch if there are fundamental limitations.
How much does a faster site help?
Speed is one factor among many, but it improves the user experience and can reduce bounces. We cannot promise a specific gain.
How often should you run technical checks?
After major changes and regularly, for example every six months, so that errors do not creep in.
