SEO audit
SEO audit for clarity on the potential and the flaws of your website.
Before any sensible SEO measures start, it has to be clear where your website actually stands in search. That is exactly what an SEO audit delivers: a structured analysis of technology, content, rankings, authority and competition that uncovers what is blocking visibility and which measures work first. Semtrix does not produce SEO audits as data graveyards but as a prioritized basis for decisions: every recommendation is rated by impact and effort and placed in a running order. Because more and more people put their questions straight to answer systems such as ChatGPT or Perplexity, Semtrix will on request also check how your brand appears there.
First review and prioritize the website in an SEO audit, then implement.
Findings are put in context, not merely counted.
You get an SEO roadmap with a running order, not a list of errors.
Definition
What is an SEO audit?
An SEO audit answers a single question in full: why does your website not have the visibility it could have? An SEO audit is a systematic review of a website from the perspective of search engine optimization, in other words the work on organic visibility. The SEO audit examines how well search engines can crawl and evaluate the website, where the technical faults sit, how strong content and rankings are, and how the website stands against the competition. It covers accessibility and indexing, the structure of the page hierarchy, loading times and Core Web Vitals, coverage of the most important search queries, the link profile and the position relative to direct competitors. The goal of every SEO audit is a clear picture of the starting point and a prioritized list of SEO measures ordered by impact and effort. An SEO audit is therefore not a report on the status quo but the basis for the next decision in the competition for visibility. A good SEO audit separates what matters from what does not, and measures both against the competition. Not every point found carries equal weight. What counts is which problems actually cost visibility and which measures pay off fastest. An automated crawl finds hundreds of flags on any larger website, and very few of them cost rankings. Only the professional assessment by Semtrix turns those flags into a running order that you and your team can start working on next Monday. An SEO audit is the first step in the Semtrix approach: diagnose the website before implementing. You get named contacts who put the results in context personally and explain them in plain language. As part of the Eskimoz group, Semtrix brings experience from more than 1,500 projects delivered since 2015. Start with a free analysis and find out what potential your website holds. An SEO audit does not replace SEO implementation, but it prevents the most expensive version of it: measures that miss the actual cause. Optimizing without a diagnosis often means writing new content for a website that search engines cannot even crawl properly. Semtrix therefore reverses the order. The SEO audit comes at the start of all SEO work on a website, not somewhere in the middle.

An SEO audit is the structured review of a website covering technology, content, rankings, authority and competition. It uncovers what is blocking visibility and rates every finding by impact and effort. The result is not a list of errors but a prioritized roadmap for the website, one you can use to decide what happens first. On request, AI visibility is added as a separate GEO section.
Experience you can verify.
Scope
What does an SEO audit at Semtrix cover?
An SEO audit at Semtrix examines the website on every level of SEO that decides visibility. The building blocks interlock: technology decides whether content is evaluated at all, content decides relevance, and authority and competition decide the position. Without a view of the competition, everything else lacks a benchmark. That is why in every SEO audit the competition stands on equal footing with your own website.

Why an SEO audit from Semtrix?
Semtrix has been in the market since 2015 and has delivered more than 1,500 projects in eleven years. As part of the Eskimoz group, with 250 consultants across Europe and named "Best Large Integrated Search Agency" at the European Search Awards 2026 in Porto, Semtrix combines solid analysis with practical implementation experience. The SEO audit is assessed and put in context by SEO specialists, not merely generated automatically. How that lands with clients is a matter of public record: 5.0 on ProvenExpert from 132 reviews and 4.8 on Google. The difference shows in the assessment. For any website, a crawler reports every missing alt text and every slow-loading page as equally important. An SEO audit from Semtrix tells you which of those findings actually cost you rankings today and which you can schedule later with a clear conscience. For data collection, Semtrix uses the Eskimoz App modules: CrawlR for technical analysis, Monitoring for the organic position per keyword and mentions in the AI Overviews, Notorious for the backlink comparison with the competition, and LLM Ranking for AI visibility. That a good SEO audit turns into long-term visibility is shown by evidenz.de: since the project started in 2022 we have increased visibility by 147 percent and traffic by 1,400 percent. Here too the starting point was an SEO audit, not the first measure. You can find out more about the team behind the SEO audit on our about us page; examples are in the case studies.

An audit is only good once it is clear what happens first.
SEO and GEO
GEO: AI visibility as a discipline of its own
A modern SEO audit does not stop at classic SEO for Google. On request, Semtrix additionally checks AI visibility, in other words whether and how a brand appears in AI answer systems such as ChatGPT or Perplexity. GEO is a discipline of its own alongside classic SEO and is reported in the SEO audit as a separate GEO section. Leaving GEO out means reviewing only half of your website's visibility. More on GEO on the pages about the GEO agency and GEO optimization.
For the SEO audit that means a second pass over the same website: once on visibility in Google, once on AI visibility through GEO. Classic SEO asks whether a website ranks. AI answer systems ask whether a statement can be cited and whether the source counts as reliable. The two are connected but follow different rules. Semtrix therefore measures GEO visibility with LLM Ranking from the Eskimoz App and reports it in the SEO audit separately from the rankings. The jury of the European Search Awards 2026 explicitly highlighted how early we moved into GEO.
Search team
Who at Semtrix produces your SEO audit and discusses it with you.
An SEO audit is only as good as the SEO specialists who assess it. At Semtrix it is handled by a fixed group of search specialists for technology, content and authority.





Process
How does an SEO audit at Semtrix work?
The process follows a clear principle: first define what the SEO audit should answer, then collect, then assess, then prioritize, then hand over. At every point you know what is being worked on, and every step ends with a result you hold in your hands.
Defining the goal
- We agree which questions the SEO audit should answer and obtain access to Search Console, Analytics and the CMS. **Your result:** a written list of the questions the SEO audit answers, plus the scope of the review.
Analysis
- Technical, content and competitive review of the website, collected with CrawlR, Monitoring and Notorious from the Eskimoz App. On request, the review of AI visibility through GEO is added. **Your result:** the complete catalogue of findings for your website covering technology, on-page, content, authority and competition.
Assessment
- Professional rating of every finding by its effect on visibility and by effort, with reasoning instead of a bare list of errors. **Your result:** every finding with a rating and one sentence on what it costs you in visibility today.
Roadmap
- The rated findings become the prioritized SEO roadmap, sorted by running order and ownership. **Your result:** the roadmap as a document, with concrete SEO measures, a running order, your position relative to the competition and who takes on what.
Handover
- A joint conversation about the roadmap, open questions and the first step you take, either yourself or with Semtrix. **Your result:** one agreed first measure with a date, and the certainty that your team can start without further questions. ---
Modules
The four review areas of the SEO audit in detail.
The technology of a website decides whether search engines evaluate its content at all. The review covers crawling and indexing, status codes and redirect chains, canonicalization, site structure and click depth, loading times and Core Web Vitals, mobile rendering, structured data and the handling of JavaScript content. CrawlR from the Eskimoz App supplies the raw data; the Semtrix consultants assess the patterns.
In the SEO audit, Semtrix reviews heading structure, metadata, internal linking and topical relevance of every important page on your website. It also checks whether internal linking strengthens the pages that matter commercially, or whether link equity drains away in archives and filter pages. This part of the SEO audit deliberately overlaps with on-page optimization, but delivers only the findings, not the implementation.
Which search queries does the website cover with its content today, which does it not, and which pieces of content serve the same intent twice? On top of that comes the comparison with the competition: which content do the websites ahead of you have that you do not, and what explains the gap? Monitoring from the Eskimoz App shows the organic position per keyword, the distance to the competition and mentions in the AI Overviews.
Quality, structure and development of the link profile as the website's authority, reviewed with Notorious in direct comparison with competitors. On request, the review of AI visibility is added: for which questions does your brand appear in ChatGPT, Perplexity and the AI Overviews, which sources are cited instead, and why? Measurement runs through LLM Ranking from the Eskimoz App. GEO runs as a separate analysis alongside the classic SEO part of the audit. ---
Result
What you hold in your hands after the SEO audit.
An SEO audit is only complete once you can work on your website with it. That is why at Semtrix the result consists of a document and a conversation, not a tool export. - The findings for the website, ordered by the areas reviewed: technology, on-page, content, authority, competition and, on request, GEO. - The assessment per finding by Semtrix, in other words why a point is relevant, what it costs you in visibility today and where it lands on the roadmap. - The prioritized roadmap for your website, with concrete SEO measures sorted by impact and effort and with ownership for each measure. - The handover conversation, in which named contacts at Semtrix put the results in context and explain them in plain language. - The benchmark for the next SEO audit of your website, so that later on it can be shown what the implementation achieved, including against the competition.





Semtrix by Eskimoz
What the Eskimoz group means for your SEO audit.
Semtrix is a global search agency: we make sure you are found wherever people search. Semtrix has been part of the European Eskimoz group since 2024. For you, the collaboration stays personal: your SEO audit is produced and discussed by a fixed team in Düsseldorf and Essen.
From the network come the Eskimoz App modules that Semtrix collects data with, instead of piecing numbers together from different tools: CrawlR for technology, Monitoring for rankings and AI Overviews, Notorious for backlinks and LLM Ranking for GEO. The combination is deliberately additive: Semtrix brings local proximity and eleven years of search experience, Eskimoz adds technology and European reach. At the European Search Awards 2026 in Porto the group was named Best Large Integrated Search Agency.

Want to know what is holding your website back?
If you are facing a relaunch, looking for the cause of a drop in rankings or simply need a solid basis, an SEO audit is the right first step. In the SEO audit, Semtrix reviews the technology, content, authority and competition of your website and shows you the order in which work on visibility pays off. It costs nothing and commits you to nothing. We do not pass your data on.
Effort & cost
What influences the effort, scope and cost of an SEO audit.
What an SEO audit costs depends on the starting situation of your website. That is why Semtrix does not work with flat-rate standard packages. First we define with you which questions the SEO audit should answer and how deep the review has to go. Only then can the effort be quoted properly. An SEO audit that answers three questions about your website thoroughly is worth more than one that ticks off thirty points superficially.
A local service provider's website with 40 URLs needs a different depth of review in an SEO audit than a shop with several thousand product pages.
Legacy issues from relaunches, redirect chains that have grown over time or a self-built CMS noticeably increase the effort for the technical SEO review in the SEO audit.
The stronger the competition for a topic, the less a look at your own website alone achieves in the SEO audit. A detailed comparison with the competition then belongs in the SEO audit.
A large body of content that has grown over time means more review effort around search intent and cannibalization, often extended by a content audit.
A large or compromised backlink profile needs its own authority analysis in the SEO audit, including an assessment of individual referring domains.
Several countries and language versions of a website bring hreflang, duplication and country-specific competition into the SEO audit. The competition is then different in every market.
Your benefits
Your benefits with an SEO audit from Semtrix.
The data collection in the SEO audit runs through the Eskimoz App modules. That keeps the data about your website comparable, even when the SEO audit is repeated later. - **Prioritization instead of a list of errors:** every finding in the SEO audit is rated by impact and effort and lands in that order on your website's roadmap. - **Reasoning for every point:** Semtrix tells you why a finding in the SEO audit costs visibility, not just that it looks unusual. - **Named contacts** who put the results in context personally and explain them in plain language. - **Usable without Semtrix:** the roadmap from the SEO audit is written so that your team can work from it without further questions. - **SEO and GEO measured separately**, so the SEO audit also shows AI visibility against the competition and names where GEO starts. - **Repeatable:** a second SEO audit measures against the same baseline and shows what the roadmap achieved for your website, including compared with the competition.
