Typical use cases

What problems Seitenreport makes visible in practice

The examples show why the structured crawl brings more than a manual individual check: technical errors, OnPage patterns and handovers are visible as prioritized tasks.

Relaunch QA

404 errors and redirect chains detected before live

Internal links on 404 pages, forwarding chains and duplicate titles were prioritized before the new website was fully rolled out.

Company website

Technical Quick Wins made visible

The check showed missing meta data, canonical anomalies, and indexable pages that weren’t relevant to search engines.

Agency workflow

Better transfer to development

Instead of confusing raw data, a prioritized task list with affected URLs, severity and concrete next steps was created.

Modern visibility

Is the content of Google, ChatGPT & AI systems properly understood?

AI readiness isn’t a separate marketing gimmick, it’s part of website analytics: indexable content, clear structure, Schema.org, trust and entity signals show whether machines can rank your website correctly.

Watch AI Readiness
Indexing

Robots, canonicals, status codes and accessible content.

Structure

Title, H1, content clarity and internal connections.

Schema.org

Organization, LocalBusiness, Breadcrumb, Product and FAQ.

Trustee

Contact, company, security and visible signs of trust.

Classify visibility

Ranking data shows where technology and content can have an impact

The crawl explains what stands out on the website. Ranking, landing page and competition data help to sort these finds by visibility potential and better prioritize page 2 opportunities.

Typical issues
  • • Which keywords are already ranking?
  • • Where are Page 2 opportunities?
  • • Which landing pages have weak top 10 coverage?
  • • Which competitors win joint SERPs?
Keywords

Organic ranking keywords

Loaded rankings show position, ranking URL, search volume, CPC and potential for next optimizations.

Chances

High volume outside top 10

Keywords on position 11 to 20 become visible as leverage: snippet, search intention, content depth, and check internal links first.

Landing pages

Prioritize Important Pages

Pages with traffic signals, but weak top 10 coverage, are merged with technical audit finds.

SERP competition

Identifying gaps in visibility

Organic competitors with common keywords help to better rank content gaps, page types and snippet approaches.

Analytical depth

The level of detail behind the audit

If the check is unlocked, it does not stay with a score. URL level, website pattern, market potential and workflow are combined to form a traceable test matrix.

Questions before the start

FAQ for SEO-Check

Responses to audit scope, free SEO check and ongoing website monitoring.

Expiration and Result

What happens after the start, how long does it take, and what do you get in concrete terms?

What do I get from the free SEO check? +

The free SEO check checks up to 20 URLs and shows the current status of your website: SEO score, initial assessments and selected finds on technical problems. With the SEO Suite from 19 € net per month, you get complete results in the tariff range and ongoing website monitoring. PDF and other exports are included from Pro.

Can I analyze my homepage for free? +

Yes. Enter the address of your homepage and start the analysis without registration. Seitenreport checks up to 20 URLs: your homepage and other accessible subpages. The free homepage analysis helps to detect technical SEO errors. You do not need installation or access to your CMS.

How do I improve my SEO score? +

The fastest way to improve your SEO score is by first fixing critical technical errors and then fixing the most important OnPage topics. Typical leverages are, for example, 4xx/5xx errors, redirect chains, missing or duplicate titles/meta data, and anomalies in canonicals and indexability. It makes sense to prioritize processing according to impact instead of individual measures without order.

How does the check go? +

You enter a domain or URL and start the crawl directly in the browser. Seitenreport then checks several pages of your website, evaluates technical SEO signals and creates a dashboard with score, prioritized finds and sample URLs. The result is accessible via a token URL and can be shared.

How long does an analysis take? +

Small websites are often ready in a few minutes. Large crawls take longer (more URLs, slow servers, many redirects). The status is updated live.

What does Seitenreport specifically test? +

Seitenreport checks, among other things, status codes, redirects, faulty URLs, titles, meta descriptions, canonicals, indexability, internal linking, technical resources and typical OnPage anomalies. The results result in prioritized findings with concrete next steps.

Does Seitenreport also test Local SEO? +

Yes. The audit checks local SEO signals on the website: address or NAP, telephone link, contact page, imprint, opening hours, arrival or maps link as well as local business and postal address scheme. This is particularly relevant for local service providers, practices, law firms, craftsmen, hotels, restaurants and other SMEs.

Is there a complete example report of Seitenreport? +

Yes. Seitenreport publishes a complete example audit of its own website. The current report, dated November 14, 2026, includes 1,471 analyzed URLs and 1,536 pages including the full technical detail appendix.

View the full example PDF · Structure and content of the report

What exactly does the report analyze? +

Technical SEO data from the crawl: status codes, redirects, titles/meta, indexability/canonicals (depending on export) and typical OnPage problems – including sample URLs.

What does the SEO benchmark show in the audit? +

The SEO benchmark compares your website to 68,000+ segmented domains and 92 SEO signals. Seitenreport ranks technical SEO, content, structure, security and indexing values in the appropriate segment, for example by country, CMS, website type or industry. So you not only see absolute errors, but also where your website is conspicuously weak or strong in the market comparison.

What is the difference between SEO Check, SEO Analysis and Website Check? +

The terms are often used similarly. One SEO check Often means a quick overview of important SEO factors, a SEO analysis rather a deeper evaluation, and an Website Check is often used more generally for technical and substantive examinations. Seitenreport combines these approaches in a crawl with prioritized measures and example URLs.

Is Seitenreport also suitable for your own company website? +

Yes. Many users start with a check of their own website to identify technical SEO problems, priorities and quick wins – as a basis for internal implementation or briefing of agency/development.

Limits & Packages

How big can the website be, which limits apply?

Is there a free entry? +

Yes. You can check up to 20 URLs for free and without login. If you want to continue monitoring your website automatically afterwards, the SEO Suite with Starter for 19 € net starts in the month. A separate audit activation is not necessary for this.

When is the SEO Suite worthwhile? +

If you want to identify new website problems early and understand the impact of your improvements. 19 € net starter per month contains full results for a website with up to 500 URLs, weekly audits, sitemap and HTTPS monitoring, and email notifications. Pro for 39 € net in the month adds more analysis depth, further monitoring, backlinks, rankings and exports.

What exactly is crawled – domain, subfolder or subpage? +

Starting point is the entered URL. We then follow internal links within the same host/domain environment (depending on crawl config). Subdomains can be included or excluded depending on the setup or analysis configuration.

How large should websites be for analysis? +

The free SEO check checks up to 20 URLs. In the SEO suite, Starter includes a website with up to 500 URLs. Pro offers 5,000, Business 20,000 and Agency 50,000 URLs together per account and crawl round; you distribute them to your projects. For a one-time analysis without a subscription, there is alternatively the website audit with up to 2,500 URLs. Larger quotas are possible on request.

Data protection, tokens & agency

Security, indexing, sharing, export/PDF and white label.

Do I need an account? +

The free SEO check starts without login. For ongoing monitoring in the SEO Suite, your account will be set up after confirmed payment; you will receive an activation link by email. No prior registration is necessary. The optional individual audit works without a suite account.

Are my analysis results public? +

The results pages are located under hard-to-guess token URLs and are not intended as public pages for search engines. In addition, report areas can be excluded from indexing by robots rule. Share the token URL only with people who should see the report.

What exports and reports are there? +

The SEO Suite contains PDF reports, Excel data folders, CSV exports as well as audit data and templates for AI from Pro. These exports are also included in the one-time unlocked website audit. Starter shows the findings in the portal. The AI package bundles a short version, structured test data and working templates and is created locally as a ZIP file.

White-Label PDF – what’s in it? +

White label outputs with branding elements such as logo, colors and customer-friendly display are possible depending on the setup or as an add-on. Details depend on the selected setup.

Still uncertain? Just start with the free first check.

You will see the first anomalies of your website in a few minutes and then decide whether you want to use full results and have your website monitored automatically.
