Black SEO Analyzer is a command-line interface (CLI) tool developed for technical Search Engine Optimization (SEO) analysis. It is designed to audit websites for factors influencing visibility in traditional search engines and AI-driven answer engines. The tool performs website crawls, supporting both standard HTML sites and JavaScript-rendered Single-Page Applications (SPAs) through headless browser integration. Its analysis capabilities cover several areas: Metadata and Structured Data Validation: It checks page titles, meta descriptions, OpenGraph tags, Twitter Cards, and Schema.org implementations for correctness and potential issues. Content Analysis: The software evaluates content using metrics like readability scores, heading structure validation (H1-H6), keyword usage, and identifies potentially thin or duplicate content across a site. Technical SEO Audit: It identifies technical issues such as broken links (404s), redirect chains, server errors, and validates configurations in robots.txt files, XML sitemaps, and canonical tag implementations. Web Performance Measurement: Black SEO Analyzer assesses performance metrics related to Core Web Vitals (LCP, CLS, FID) and other page speed indicators, providing data on resource loading and execution. AI Integration: The tool can connect to Large Language Models (LLMs) including OpenAI (GPT), Anthropic (Claude), DeepSeek, and Google Gemini. Users provide their own API keys (BYOK model) to enable AI-powered analysis of page content, generation of SEO recommendations, and insights based on customizable prompts. Reporting: Analysis results can be exported in various formats including JSON, JSONL, CSV, XML, and HTML. It offers customizable HTML templates for generating branded reports. Black SEO Analyzer operates locally and is intended for users comfortable with command-line environments, such as developers, system administrators, and technical SEO specialists. It facilitates integration into automated workflows, including CI/CD pipelines. The software is offered under a one-time purchase license model, which includes lifetime access and a source code availability guarantee under specific conditions (e.g., product discontinuation). A free version with limited page analysis is available for evaluation.
