SAGE - AI SEO, AEO & GEO Engine

SEO checker, AEO & GEO analyzer — audit meta tags, schema markup, headings, AI search optimization & SERP rankings in one click.

SAGE is a free AI-powered SEO checker, AEO analyzer, and GEO optimization tool — built as a Chrome extension for the new search landscape. Audit any webpage for search engine optimization, answer engine readiness, and generative AI visibility in one click. 100% local analysis — your data never leaves your browser. SAGE runs 200+ checks across 15 categories, scores your page 0–100 on three pillars — SEO, AEO, and GEO — and tells you exactly what to fix and why. Whether you're optimizing for Google, AI Overviews, ChatGPT, Claude, Gemini, or voice search, SAGE gives you a clear, actionable report in seconds. What SAGE Analyzes SEO (Search Engine Optimization) • Meta tags, title, and description quality • Open Graph and Twitter Card validation • URL structure and slug optimization • Keyword density with stuffing detection • Image optimization (WebP/AVIF detection, alt text) • Heading hierarchy and semantic HTML • Canonical URLs, sitemaps, and crawlability • DOM size, render-blocking resources, and performance • HTTPS enforcement and redirect analysis • Internal linking structure GEO (Generative Engine Optimization) • robots.txt analysis for AI bot blocking (GPTBot, CCBot, ChatGPT-User, etc.) • llms.txt and llms-full.txt detection • Machine readability scoring • Structured data completeness for LLM citation • Entity and authority signals (authorship, organization, sameAs) • Citability and answer-readiness of content • Accessibility for AI agents (ARIA, labels, roles) • WebMCP endpoint detection AEO (Answer Engine Optimization) • Featured snippet targeting (position zero readiness) • Question-answer structure detection • Voice search readiness and conversational tone • Flesch-Kincaid readability grading • Sentence and paragraph length optimization • Speakable schema detection • People Also Ask (PAA) style content analysis Features Three-Tab Dashboard Switch between SEO, GEO, and AEO views. Each tab shows its own pillar score, category breakdowns, and prioritized recommendations — so you focus on what matters for your goal. Weighted Scoring System Not all checks are equal. SAGE weights categories by impact — Structured Data (1.5x), Machine Readability (1.5x), Technical SEO (1.2x) — giving you a score that reflects real-world ranking factors. Letter grades (A through F) make results instantly understandable. Actionable Fix Recommendations Every failing check comes with a specific fix: what to change, why it matters, and which pillars it affects. Fixes are tagged by impact (high, medium, low) so you can prioritize effectively. Schema Generator SAGE detects your page type — Article, FAQ, Product, Local Business, SaaS, Homepage — and generates ready-to-use JSON-LD structured data. Copy it directly into your page's . Supports FAQPage, HowTo, Article, Product, LocalBusiness, SoftwareApplication, WebSite, and more. Readability Analysis Built-in Flesch-Kincaid scoring tells you the reading grade level of your content. Optimized for voice search, which favors content written at a 6th–8th grade level. Keyword Density Analysis Extracts the top keywords from your page, calculates density percentages, and checks whether they appear in your title, H1, and meta description. Warns you if density exceeds natural thresholds. Social Preview Validation Checks your Open Graph and Twitter Card metadata to ensure your pages look right when shared on social platforms. SERP Overlay See SEO scores directly on Google search results. SAGE overlays optimization data on every result so you can compare your page against competitors without leaving the SERP. Export Reports Export your full analysis in multiple formats: • Interactive HTML report (with its own dark/light theme toggle) • PDF (print-optimized) • Markdown (full report or recommendations only) • CSV (full data or recommendations only) • Plain text Score Tracking SAGE remembers your previous scan and shows score deltas — so you can see whether your changes improved or hurt your optimization after each edit.
