517 checkpoints 350+ automated + 153 depending on context

What checks does the SEO audit contain?

The Seitenreport SEO and website analysis currently includes 517 checkpoints. Of which: 350+ checks automated: 238 URL checks and 126 website-wide checks. Other 153 Test points cover manual, heuristic and contextual audit modules – via Crawling, indexing, technical structure, meta data, content, internal linking, performance, structured data, security, accessibility and data protection.

Instead of showing only individual signals, the audit bundles automatic URL checks with manual classification, heuristic patterns and page type-specific special checks. Findings are prioritized by severity, practical impact, and page type. The superordinate test fields are at a glance SEO audit areas summarised.

How the checks are set up
Automatic

Technical signals such as status codes, canonical, meta data, header, JSON-LD, image attributes or basic checks on crawling and rendering.

Heuristic

Patterns and risk indicators such as soft 404 suspicions, thin content indicators, render blocking, URL patterns or hero/LCP-related anomalies.

Manual / Context

Topics such as Faceted Navigation, IA, Intent Match, Relaunch Risks, Consent, E-E-A-T, Competition Logic and Page Type-specific Special Cases.

Per website type

Additional checking logics for shops, local SEO, news/publisher pages, media sites, international websites, migrations or JS frontends – including location, contact, NAP and schema signals based on the current audit status with 517 checkpoints in total.

Single tool vs. complete audit

Single tools are useful if you want to quickly check a single signal. However, the actual added value of an SEO audit arises when several signals are evaluated and prioritized together.

Standalone SEO Tool
  • • Checks a single signal
  • • Good for robots.txt, Sitemap, Canonical or hreflang
  • • Faster start with clear individual questions
  • • Little context about impact and page type
A complete SEO audit
  • • evaluates several signals related
  • • Prioritizes finding according to severity and practical impact
  • • Recognizes patterns across templates, page types and URL groups
  • • considers special cases such as relaunch, JS, filters, shops or internationalization
Individual tools check individual signals. The audit currently bundles 238 automatic URL checks, 126 website-wide checks and other manual or context-dependent modules into a prioritized work basis.

Why this page can be much more detailed

The more transparent the checks are described, the clearer the equivalent of the audit. This strengthens trust, scope understanding and conversion.

What Users Should Understand Here

Not only that: is tested, but What exactly, in which depth and why some topics can be evaluated automatically, but others only in the project context.

Bridge to the product

The page explains the scope. The PDF audit then provides the concrete evaluation, prioritization and URL-related finds for the checked website.

Audit depth by area

In addition to the categories, the audit scope can also be described by technical depth. Especially for agencies, in-house teams and more demanding websites, this perspective is often more helpful than a pure list of topics.

Basic examination

Measurable signals such as status codes, indexability, meta data, header structure, canonicals, links, images, social tags and headers.

Pattern recognition

Heuristic indications of quality issues, unusual page type patterns, link poverty, template repetitions, render risks and thin content symptoms.

Project context

Evaluation of relaunch, internationalization, e-commerce, consent, tracking, news/publisher requirements and prioritization according to business impact.

Area Automatic Heuristic / Partially Manual / Context
Crawling and indexing Status, redirects, robots, canonicals, sitemaps Soft 404 or crawl trap indicators Filter logic, facets, index strategy
Meta, Structure & SERP Titles, Descriptions, Hx, OG/Twitter Snippet and Template Pattern SERP positioning and page type matching
Content & IA Word number, headings, duplicate signals Thin Content and Boilerplate Instructions Intent, theme coverage, cannibalization
Links, Media & Technology Broken Links, ALT Texts, Headers, Security Internal link poverty, render and LCP risks Prioritization per template, page type and funnel
