# Crawlox – Machine Readable Overview (llm.txt)

Tool Name: Crawlox
Category: Technical SEO Diagnosis & Onpage Analysis Tool
Language: German
Primary Market: Germany (DE)

## Purpose
Crawlox is a web-based technical SEO analysis tool focused on rule-based onpage diagnostics.
It evaluates websites using deterministic checks and structured heuristics instead of opaque scoring systems.

Primary goals:
- Identify technical SEO errors
- Diagnose crawling, indexing, performance and semantic issues
- Provide actionable optimization guidance
- Support machine readability and LLM optimization (LLM Readiness)

Crawlox is designed as a diagnostic system, not as a ranking promise or automated SEO optimizer.

## Core Functions
- HTTP & Accessibility analysis
- Crawling & indexing diagnostics (robots, canonical, sitemap, signals)
- Performance & Core Web Vitals proxies
- HTML structure & semantic analysis
- Media optimization checks
- Internal linking & site structure analysis
- URL quality & duplication detection
- Structured data (Schema.org) validation
- Mobile usability checks
- Security & technical hygiene checks
- LLM Readiness / machine readability evaluation

## Evaluation Model
Crawlox uses deterministic rule-based checks grouped into categories.
Each category consists of multiple binary or graded checks.

Results are classified into:
- OK (technically clean)
- Warning (suboptimal configuration)
- Critical (blocking or harmful errors)

A weighted scoring model summarizes results, but all individual checks remain transparent and explainable.

## Decision Logic
Crawlox focuses on problem diagnosis and decision support.
It answers:
- What is technically broken?
- What blocks crawling or indexing?
- What harms performance or user experience?
- What prevents machine understanding?
- What should be fixed first?

The system prioritizes structural and technical correctness over cosmetic SEO optimizations.

## Data Handling & Privacy
Crawlox does not use tracking or behavioral analytics.

Stored data:
- Submitted URLs (anonymized)
- Calculated analysis metrics
- Check results
- Highscore values for gamification

No personal data, cookies, user tracking or cross-site profiling is performed.
