SEO analysis and SEO audit

The scope depends on your goals. These areas are usually included:

• Visibility, rankings and competitors: we evaluate visibility and ranking data, look for anomalies over time and compare your website with the competitors that rank ahead of you for your important search terms.
• Crawling and indexing: we crawl the website like a search engine bot and check whether all pages are reachable, correctly linked and canonicalised. This includes redirects and 404 pages, indexing and, for international websites, the mapping of language and country versions.
• Loading time and page structure: Core Web Vitals, loading speed, HTML structure and semantics, and the basics of accessibility. A full accessibility review is a separate service: accessibility audit.
• Content: we check whether the pages match the search terms, along with page titles and descriptions, image descriptions, text length and duplicate content.
• Links: internal linking and backlinks, including links that point to pages which no longer exist.
• Data: Google Search Console and web analytics show which pages and search queries bring visits and where they are falling.

An SEO audit does not replace a full keyword analysis or a content strategy. The audit reviews the existing pages. Which topics are missing is clarified by the keyword analysis with content strategy. How often AI systems such as ChatGPT mention your brand is covered by the GEO audit.

You receive a written report and a spreadsheet with the affected pages. The report is structured so that management, marketing and developers can all work with it:

• Summary: the most important findings and what needs doing first.
• Findings: each finding describes the current state, the impact and the action, and carries a traffic-light rating.
• Affected pages: each finding comes with the list of affected URLs, not just one example.
• Action list: all actions in one list, each with its traffic-light rating and effort. We state the effort as low, medium or high.

We explain our recommendations so that you can follow every step. On request we turn them into tasks for your developers, with URL lists, sample code and an acceptance criterion.

Five examples. In three of them the audit came at the start of the collaboration, in two it was added later. An audit alone achieves nothing. It determines what is done first. The figures come from SISTRIX for Germany, as of 28 September 2026. The SISTRIX Visibility Index expresses in a single figure how well a website is found on Google across a large number of search terms. The case studies are available in German only.

• Regional service provider: the kick-off in September 2021 was followed by a crawl, a workshop and an SEO audit with an action list. Today five times as many keywords rank in the top 10 as two years earlier. Case study (in German)
• Company with several specialist departments: the engagement in 2021 comprised an SEO audit, keyword analysis and content strategy. Since the relaunch of the website in December 2025, visibility has risen by 160 per cent. Case study (in German)
• Nationwide organisation: started in August 2020 with an SEO audit, keyword analysis and content strategy. From 2021 to 2023 we reviewed the technical set-up in regular follow-up reviews (health checks). 2.5 times as many keywords rank in the top 10 as at the start. Case study (in German)
• Manufacturer with several online shops: the first engagement came in May 2022. In spring 2024 a technical audit with a record of findings and a priority list followed, and after it the restructuring of navigation and categories. Since May 2022 the visibility of the main domain has increased 4.5-fold. Case study (in German)
• ROMA, manufacturer of roller shutters and sun protection: we have managed SEO and content since April 2025. In 2026 we also reviewed the international website roma.eu in an SEO audit. ROMA case study (in German)
