Get answers to common questions about Black SEO Analyzer from technical implementation to licensing
Black SEO Analyzer is built for technical professionals who live in the terminal. Command-line tools offer unmatched automation capabilities, seamless CI/CD integration, and the ability to process massive datasets without GUI overhead. You can pipe outputs, chain commands, schedule cron jobs, and integrate directly into your existing development workflow. This isn't about being difficult—it's about being powerful.
Absolutely. We've built a sophisticated multi-strategy crawling engine that includes headless Chrome integration specifically for JavaScript-heavy sites. Whether you're auditing React, Angular, Vue.js, or any other SPA framework, our browser-based crawler fully renders JavaScript content before analysis. The tool automatically detects when browser rendering is needed and switches strategies accordingly.
Our vector-based semantic analysis uses machine learning embeddings from providers like OpenAI, Google Gemini, or Ollama to convert page content into high-dimensional vectors. We then calculate cosine similarity between pages to detect semantic duplicates (default threshold: 0.95) and measure content relevance to your site's overall theme via centroid analysis (default threshold: 0.7). This goes far beyond simple text matching to understand actual content meaning and relationships.
We support seven output formats to fit any workflow: JSON for API integration, JSONL for streaming processing, XML for enterprise systems, CSV for spreadsheet analysis, CSV Flat for simplified data, HTML Folder for beautiful reports with navigation, and JSON Files for distributed processing. Each format is optimized for different use cases, from automated pipelines to stakeholder presentations.
Unlike "black box" GUI tools, Black SEO Analyzer provides complete transparency and control. You get raw, unfiltered data with exact technical details about why something is flagged as an issue. Built in Rust for blazing performance, it combines traditional SEO metrics with AI-powered insights and advanced semantic analysis. Plus, with our lifetime license model, you own the software—no subscriptions, no vendor lock-in.
We go deeper than any mainstream crawler. Beyond basic on-page checks, we analyze Core Web Vitals (LCP, FID, CLS, FCP, TTI, TBT), security headers, CSP policies, SSL certificates, render-blocking resources, JavaScript performance, structured data validation (JSON-LD, Microdata, RDFa), hreflang implementation, canonical chains, redirect paths, and much more. Every technical aspect that impacts SEO is covered.
Yes, extensively. You can configure crawling parameters (concurrency, rate limits, user agents), customize HTML report templates with your branding, define custom AI prompts for specialized analysis, adjust semantic analysis thresholds, select specific content areas for analysis via CSS selectors, and control output formats and data structures. The tool is designed to adapt to your specific requirements.
Our AI integration supports multiple providers (Anthropic Claude, OpenAI GPT, DeepSeek, Google Gemini) with a Bring Your Own Key (BYOK) model for security. AI analysis provides content optimization suggestions, generates meta tags, identifies content gaps, performs competitive analysis, and offers strategic SEO recommendations. You can use our default prompts or create custom ones for your specific use cases.
We believe in true software ownership. Technical professionals need tools they can rely on indefinitely, not services that disappear when you stop paying or the company pivots. Our one-time purchase model means you own the software forever, with all future updates included. This aligns with how professional tools should work—buy once, use forever.
Our source code guarantee is a legally-binding commitment that protects your investment. If we ever discontinue the product, cease operations, or fail to provide updates for 12+ consecutive months, you automatically gain access to the full source code. This means you can continue using, modifying, and maintaining the software indefinitely, regardless of what happens to our company. It's true software ownership.
Everything. The single license includes unlimited URL and site analysis, all current and future features, AI integration capabilities (BYOK), semantic analysis engine, all output formats, custom template support, lifetime updates, and our source code guarantee. There are no feature tiers or hidden limitations—you get the complete professional tool.
Our Source Code Guarantee is a legally binding commitment that ensures your long-term access to the software. If we ever discontinue the product, cease operations, or fail to provide updates for 12 consecutive months, you automatically gain full access to the complete source code. This empowers you to continue using, modifying, and maintaining the software indefinitely, providing true ownership and peace of mind.
The agency license ($1,999) provides volume licensing for teams and agencies. It includes everything in the single license but allows multiple team members to use the tool. It's perfect for agencies handling multiple client accounts, in-house teams standardizing on one tool, or consultants who need to deploy across client environments. Volume discounts are available for larger teams.
Black SEO Analyzer runs on Windows, macOS, and Linux. Built in Rust, it's incredibly efficient with minimal system requirements. For JavaScript rendering, you'll need Chrome or Chromium installed. The tool automatically detects your browser installation. For AI features, you'll need API keys from your chosen providers. That's it—no complex dependencies or runtime environments.
Integration is straightforward. The command-line interface accepts all parameters as arguments, making it perfect for automation. You can run it in your build pipeline to catch SEO regressions, schedule regular audits via cron, or trigger analysis on deployment. Output formats like JSON and XML make it easy to parse results and fail builds on critical SEO issues. We provide example scripts for popular CI/CD platforms.
While Black SEO Analyzer is designed for technical users, we've included an interactive mode that guides you through the process. However, to fully leverage its power—automation, scripting, pipeline integration—command-line familiarity is beneficial. If you're looking for a point-and-click solution, this might not be the right fit. But if you're ready to level up your technical SEO game, the investment in learning will pay dividends.
Updates are distributed through our GitHub releases page. The tool includes a built-in version checker that notifies you when updates are available. Simply download the new binary and replace your existing one—your license and configurations remain intact. All updates are included with your purchase, forever. We typically release updates monthly with new features, performance improvements, and bug fixes.
Yes, Black SEO Analyzer excels at competitive analysis. You can crawl competitor sites to understand their technical implementation, content structure, and optimization strategies. The AI integration can provide insights on content gaps and opportunities. The semantic analysis engine can identify topic clusters and content strategies. Export the data to compare multiple competitors side-by-side.
Built in Rust with an asynchronous architecture, Black SEO Analyzer handles massive sites efficiently. Configure concurrent requests and rate limiting to match server capacity. The streaming output formats (JSONL) allow processing results as they're generated, preventing memory issues. For sites with millions of pages, you can segment crawls by subdomain or directory, then aggregate results programmatically.
Absolutely. The structured output formats make it easy to build custom analysis scripts. Parse JSON output to create custom metrics, integrate with your data warehouse, or build automated reporting systems. Many users create wrapper scripts for specific use cases like monitoring Core Web Vitals trends, tracking structured data implementation, or validating SEO requirements in staging environments.
The tool includes intelligent rate limiting and retry logic for AI API calls. You can configure request delays and concurrent API calls. For large-scale analysis, we recommend using providers with higher rate limits or running multiple instances with different API keys. The tool gracefully handles rate limit errors and continues analysis, marking pages that couldn't be AI-analyzed for later processing.
