Ever wonder what keeps your website from truly shining in search results and AI answers? Black SEO Analyzer is built in Rust, offering a no-nonsense, comprehensive website audit. It's where traditional SEO meets cutting-edge AI, giving you both command-line power and a friendly GUI. This isn't just another crawler; it's your secret weapon to ensure your site isn't just seen by Google, but truly understood by the AI systems shaping tomorrow's search landscape.
In this wild digital universe, getting your site's structure and metadata dialed in isn't just crucial for rankings—it's about making sure AI can find and grasp your content when people ask about what you do. Black SEO Analyzer cuts through the corporate buzzwords and gives you the raw, actionable data you need. No more getting left behind when someone asks an AI about exactly what you sell. It's time to get your site's momentum going.
View on GitHubThink of a web spider (or crawler, or bot) like a digital explorer. Its job? To systematically browse the internet, just like you might explore a new city, but for a very specific purpose: indexing the web for search engines. These programs "crawl" the internet, following links from one page to the next, soaking up information about websites.
Black SEO Analyzer is your personal, powerful web crawler. It's built to mimic exactly how search engines and AI systems discover and process your website's content. You give it a starting URL, and it dives in, following every internal link, systematically mapping out your entire site. As it goes, it grabs all the critical data: content, metadata, technical bits, and performance metrics. This deep dive means nothing gets overlooked, giving you the full, unvarnished truth about your site's SEO health.
Want your reports to look sharp and on-brand? Black SEO Analyzer lets you generate branded, responsive, and interactive analysis reports with fully customizable HTML templates. Tailor the look and feel to match your company's vibe, complete with custom styling and logo integration. It's about making your insights shine.
Dive deep into your content with comprehensive analysis: word count, keyword density, and Flesch-Kincaid readability scores. We'll validate your heading structures (H1-H6), sniff out duplicate content (both exact and semantic), and pinpoint those crucial content gaps and opportunities you've been missing.
Get your data how you need it. Generate comprehensive reports in multiple formats: JSON, JSONL, XML, CSV, CSV Flat, and full HTML folders. Each report comes packed with executive summaries, detailed per-page breakdowns, performance metrics, and clear, actionable recommendations. No more guessing, just doing.
Page speed is momentum. We assess Core Web Vitals (LCP, FID, CLS) and other key performance metrics (FCP, TTI, TBT). We'll analyze resource loading, critical rendering paths, caching, compression, and image/script optimization, giving you solid recommendations to boost your page speed and user experience. Get that site flying!
This isn't just an SEO tool; it's your AI SEO analysis powerhouse. Black SEO Analyzer integrates with leading LLMs (Anthropic Claude, OpenAI GPT, DeepSeek, Google Gemini). Bring your own keys (BYOK) and unleash custom prompts for AI-driven content optimization, meta tag generation, strategic SEO recommendations, and sharp competitive/content gap analysis. It's like having an AI SEO expert on your team.
Technical issues can be black holes for your SEO. We'll find them: broken links, redirect chains, server errors. We validate your URL structures, HTTPS implementation, SSL certificates, robots.txt compliance, XML sitemaps, and canonical URLs. This ensures search engines and AI systems can crawl and index your site perfectly, keeping your momentum strong.
Your site's metadata is its handshake with search engines and AI. We validate all essential meta tags (title, description, keywords, viewport, robots, canonical), Open Graph Protocol, and Twitter Cards. Plus, we perform comprehensive Schema.org markup validation (JSON-LD, Microdata, RDFa) ensuring your site speaks the right language to both traditional search and AI answer engines.
Whether it's a classic site or a modern Single-Page Application (SPA), our multi-strategy crawling engine handles it. We use fast HTTP-only requests for static content and headless Chrome for JavaScript-heavy sites. Configure concurrent requests, rate limiting, and user agents, with automatic sitemap processing and content hashing for bulletproof duplicate detection. No site is too complex.

No more vague suggestions. Get concrete, direct advice from the AI on how to supercharge your page titles, meta descriptions, content structure, keyword usage, and overall SEO performance. It's like having a seasoned SEO consultant, but faster and always on point.
Use AI analysis to spot those elusive content gaps, brainstorm fresh topic ideas, and truly understand how your pages might be interpreted by the ever-evolving AI answer engines. This ensures your content isn't just visible, but truly impactful in the new search landscape.
