    description
    SeoBrowser — быстрый, приватный, локальный технический SEO-чекер.
    
    Один клик по иконке в панели инструментов (или открытие боковой панели) — и страница, которую вы сейчас просматриваете, прошла аудит по трём современным дисциплинам:
    
      • SEO  — классическая оптимизация под поисковые системы
      • GEO  — Generative Engine Optimisation (Perplexity, ChatGPT, Gemini, Claude)
      • AEO  — Answer Engine Optimisation (расширенные сниппеты, голосовые ответы)
    
    Аудит выполняется за 1–3 секунды и формирует структурированный отчёт из двенадцати специализированных вкладок и сводной оценки соответствия по 33 взвешенным критериям AIO/GEO/AEO.
    
    🔍 ЧТО ПРОВЕРЯЕТ
    
    • Overview      — title, meta-description, canonical, meta-robots, Open Graph, Twitter Card, security headers, charset, lang, viewport
    • Content       — количество и текст H1, иерархия заголовков, количество слов, отношение текст/HTML, плотность сущностей
    • Links         — счётчики внутренних/внешних, пустые анкоры, неинформативные анкоры, цитирования авторитетных источников, тематические кластеры, энтропия анкоров
    • Hreflang      — количество, валидность ISO-кодов, x-default, self-reference
    • Images        — наличие alt, width/height, lazy-loading, обнаружение битых картинок, классификация декоративных vs смысловых
    • Schema        — парсинг JSON-LD/Microdata/RDFa; полнота Article / Organization / FAQPage / Person / Product / BreadcrumbList; глубокая валидация полей; свежесть Article
    • Performance   — LCP, CLS, FCP, TTFB, размер DOM, количество ресурсов (через PerformanceObserver, по реальным данным)
    • AI Crawlers   — парсинг robots.txt + решение по доступу для каждого бота (GPTBot, ClaudeBot, PerplexityBot, GoogleOther и др.)
    • llms.txt      — наличие, структура, целостность ссылок (стандарт llmstxt.org)
    • Agent Readiness — 10 проверок well-known: sitemap, Link header (RFC 8288), content negotiation Markdown, agent-skills, api-catalog, MCP server card, OAuth & OpenID configuration, ai.txt, ai-preferences
    • Crawler View  — что видят AI-краулеры БЕЗ JavaScript: покрытие raw-HTML, доля основного контента, token bloat, anti-bot сигналы, симуляции пяти ботов
    • AEO           — answer-first параграфы, вопросительные заголовки, информационная плотность, наличие таблиц, семантическое разбиение, voice-friendly первый абзац, выравнивание под position-zero
    
    📊 AIO / GEO / AEO ОЦЕНКА
    
    Отдельная вкладка суммирует 33 взвешенных критерия по пяти уровням (S — критичные, A — высокого влияния, B — средние, C — специализированные, D — перспективные). У каждого критерия — вес уровня, дисциплина (AIO/GEO/AEO), статус (PASS/WARN/FAIL/INFO) и сниппет «Скопировать фикс» в один клик для семи ключевых пунктов. Можно фильтровать по дисциплине, фокусироваться на одной (вес ×1,5), или смотреть итоговый процент соответствия по 100-балльной шкале.
    
    🔒 ГАРАНТИИ ПРИВАТНОСТИ
    
      • Весь анализ — только на вашем устройстве. Содержимое страницы НЕ покидает браузер.
      • Никакой аналитики, телеметрии, отчётов об ошибках, рекламных SDK.
      • Никаких сторонних сетевых запросов.
      • Аудит делает небольшое количество запросов к тому же домену (robots.txt, sitemap.xml, /.well-known/* и т. д.) — это публично доступные ресурсы, которые сама страница могла бы запросить. Запросы идут с `credentials: 'omit'` и `referrerPolicy: 'no-referrer'`.
      • История аудитов (последние 100) хранится только в IndexedDB вашего браузера. В любой момент можно очистить через вкладку «История».
      • Manifest v3, никаких `host_permissions`, только шесть минимальных разрешений: activeTab, storage, scripting, contextMenus, sidePanel, alarms.
      • Полная политика конфиденциальности: https://seobrowser.ru/privacy
    
    ⚙️ ЭКСПОРТ ОТЧЁТА
    
    Каждый аудит можно экспортировать в JSON, CSV (UTF-8 BOM — Excel корректно отображает кириллицу), Markdown, AI-prompt (вставьте в ChatGPT/Claude, чтобы получить план фикса под ваш контент), или специальный AIO/GEO/AEO Markdown-дайджест.
    
    🌐 ЯЗЫКИ
    
    Интерфейс: английский, русский (автоматически выбирается по языку Chrome).
    Тексты находок анализаторов: английский (работает на страницах на любых языках, включая русский).
    
    📍 КОМУ ЭТО НУЖНО
    
      • SEO-специалистам, проводящим on-page аудиты для клиентов
      • Контент- и growth-командам, оптимизирующим контент под цитирования в ChatGPT/Perplexity/Gemini
      • Продуктовым инженерам, проверяющим schema, hreflang, Open Graph и Core Web Vitals перед деплоем
      • Разработчикам, выпускающим MCP / agent-skills / llms.txt для интеграции с AI-агентами
      • Всем, кто хочет мгновенно увидеть, как AI-краулер видит конкретную страницу
    
    🚀 БЫСТРО. ПРИВАТНО. ТЩАТЕЛЬНО.

    One click on the toolbar icon (or a tap on the side panel) audits the page you are currently viewing across three modern disciplines:
    
    • SEO - classical search-engine optimisation
    • GEO - Generative Engine Optimisation (visibility in AI answer engines)
    • AEO - Answer Engine Optimisation (featured snippets, voice answers)
    
    The audit completes in 1–3 seconds and produces a structured report with twelve specialist views and an AIO/GEO/AEO compliance score across 33 weighted criteria.
    
    🔍 WHAT IT INSPECTS
    
    • Overview - title, meta-description, canonical, robots, OG, Twitter Card, security headers, charset, lang, viewport
    • Content - H1 count + text, heading hierarchy, word count, text-to-HTML ratio, entity coverage
    • Links - internal vs external counts, empty anchors, generic anchors, authoritative outbound citations, topical clusters, anchor entropy
    • Hreflang - count, ISO validity, x-default, self-reference
    • Images - alt coverage, width/height, lazy-loading, broken-image detection, mixed-content (insecure http on https) detection, decorative-vs-meaningful classification
    • Schema - JSON-LD, Microdata, RDFa parsing; completeness checks for the GEO-critical schema.org types (Article, Organization, FAQPage, Product and more) plus opportunistic bonus types; deep field validation; Article freshness
    • Performance - LCP, CLS, FCP, TTFB, DOM size, resource counts (live PerformanceObserver)
    • AI Crawlers - robots.txt parse (incl. Sitemap directive) + per-bot access decision across 44 tracked AI crawlers, grouped by purpose: model training, live retrieval, and indexing
    • llms.txt - presence, structure, link integrity (the emerging llmstxt.org standard)
    • Agent Readiness - 10 well-known probes: sitemap, RFC 8288 Link header, Markdown content negotiation, agent-skills, api-catalog, MCP server card, OAuth & OpenID configuration, ai.txt, ai-preferences
    • Crawler View - what AI crawlers see WITHOUT JavaScript: raw-HTML coverage, main-content ratio, token bloat, anti-bot signals, five simulated bot perspectives
    • AEO - answer-first paragraphs, question headings, info density, table presence, semantic chunking, voice-friendly first paragraph, position-zero alignment
    
    📊 AIO / GEO / AEO SCORE
    
    A separate tab summarises 33 weighted criteria across five tiers (S - Critical, A - High Impact, B - Medium, C - Specialised, D - Forward-Looking). Each criterion has a tier weight, a discipline (AIO / GEO / AEO), a status (PASS / WARN / FAIL / INFO), and a one-click "Copy fix" snippet for the ten highest-impact items. Filter by discipline, focus on a discipline (1.5× weight), or read the un-focused 100-point compliance percent.
    
    🖥️ INTERFACE & WORKFLOW
    
    • Redesigned, dense, technical UI with light / dark / system theme
    • Run it as a toolbar popup or as a full-height side panel - your choice
    • Filter and search findings; expand any finding to the raw underlying elements (the actual empty anchors, alt-less images, schema blocks)
    • Compare any two saved audits side-by-side in History to track regressions
    • First-run onboarding, and a keyboard shortcut (Alt+Shift+S) to open the audit instantly
    • Every WARN/FAIL states the exact threshold it missed - no guessing why
    • The footer shows the installed version and flags when a newer version is available
    
    🔒 PRIVACY GUARANTEES
    
    • All processing happens on your device. Page content NEVER leaves the browser.
    • No analytics, no telemetry, no error reporting, no advertising SDKs.
    • No third-party network requests.
    • The audit makes a small set of same-origin probes (robots.txt, sitemap.xml, /.well-known/*, etc.) - these are publicly addressable resources the page itself could request. They are sent with `credentials: 'omit'` and `referrerPolicy: 'no-referrer'`.
    • Audit history (last 100 audits) is stored in your browser's IndexedDB only. Clear any time via the History tab.
    • Manifest v3, no `host_permissions`, only six minimum permissions: activeTab, storage, scripting, contextMenus, sidePanel, alarms.
    • Open privacy policy: https://seobrowser.ru/privacy
    
    ⚙️ EXPORT
    
    Every audit can be exported as a self-contained, shareable HTML report (single file, no external resources), JSON, CSV (UTF-8 BOM, Excel-friendly), Markdown, AI-prompt (paste into your AI assistant for tailored remediation), or a dedicated AIO/GEO/AEO Markdown digest.
