# VektorAI — Full Documentation for AI Crawlers > AI visibility audit platform — 100+ checks across SEO, AEO, GEO and Performance. > Website: https://vektorai.io > For the summary version, see: https://vektorai.io/llms.txt --- ## What is VektorAI? VektorAI is an AI visibility audit platform that scans any public URL against 100+ checks across four pillars: 1. **SEO (Search Engine Optimization)** — 40+ on-page checks including title tags, meta descriptions, heading hierarchy, image alt text, canonical URLs, Open Graph tags, Twitter Cards, robots directives, and internal linking. 2. **AEO (Answer Engine Optimization)** — 20+ checks for AI answer engine readiness including JSON-LD structured data (FAQPage, HowTo, Article, Organization, BreadcrumbList), llms.txt presence, entity markup, speakable content, and E-E-A-T signals. 3. **GEO (Generative Engine Optimization)** — 25+ checks for generative AI citation readiness including content quotability, authoritative sourcing, unique statistics, fluency signals, and technical accuracy markers. 4. **Performance** — Core Web Vitals via Google PageSpeed Insights API including LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), TBT (Total Blocking Time), FCP (First Contentful Paint), and TTFB (Time to First Byte). Each check produces a severity level (Critical, Warning, or Info) and a copy-paste fix when applicable. The final score per pillar is 0-100, calculated as a weighted pass/fail ratio where Critical issues count 3x, Warnings 2x, and Info 1x. --- ## Core Features ### AI Visibility Audit URL: https://vektorai.io/features/audit Run a comprehensive audit on any public URL. The audit engine: - Fetches the page HTML and parses it server-side using linkedom - Runs 100+ individual checks organized by pillar (SEO, AEO, GEO, Performance) - Produces severity-ranked issues (Critical > Warning > Info) - Generates copy-paste HTML/JSON fixes for every actionable issue - Calculates a 0-100 score per pillar using weighted severity scoring - Extracts page context (title, meta description, headings, JSON-LD, OG tags, author, dates) for AI Fix Anonymous audits are available for free with limited results. Authenticated users get full results. Pro users get unlimited audits. ### AI Fix Suggestions URL: https://vektorai.io/features/ai-fix AI Fix runs entirely in the browser using WebLLM (WebGPU-accelerated local inference). No data leaves the user's machine. Three fix tiers: - **Tier 1 — Deterministic Fixes**: Direct HTML tag generation (e.g., missing canonical, missing viewport). No AI needed. - **Tier 2 — Content-Aware Fixes**: AI generates improved titles, meta descriptions, headings, and image alt text using extracted page context. - **Tier 3 — Structured Data Generation**: AI generates complete JSON-LD blocks (FAQPage, Article, Organization, BreadcrumbList) based on page content analysis. Performance issues are excluded from AI Fix as they require infrastructure changes. ### Competitor Compare URL: https://vektorai.io/features/compare Benchmark your site against up to 3 competitors simultaneously: - Runs a full VektorAI audit on all pages in parallel - Produces side-by-side score comparison across all four pillars - Gap analysis showing where competitors outperform you and by how much - Priority fixes ranked by competitive impact - Pro feature requiring an active subscription. ### Scheduled Monitors URL: https://vektorai.io/features/monitors Automated re-audits with configurable frequency: - Set up monitors for any URL with daily, weekly, or monthly schedules - Alert threshold: get notified when scores drop below a set value - Score trend tracking with historical charts - Email alerts on significant score changes - Up to 10 monitors per Pro account ### Reports & Score Tracking URL: https://vektorai.io/features/reports Per-site score history and tracking: - View all audits grouped by hostname - Run history with score comparisons between runs - Trend indicators showing improvement or regression - PDF report downloads for client reporting ### AI Citation Tracking URL: https://vektorai.io/features/citations Track whether AI search engines cite your domain for target keywords: - Set up a tracker with your domain and up to 10 target keywords - Weekly automated checks against AI-powered search engines - Visibility score (0–100) combining citation rate, position, and AI answer mentions - Position tracking with week-over-week changes - AI answer detection — know when your domain is mentioned in AI-generated answers - Competitor analysis — see which domains rank alongside you for each keyword - Pro feature requiring an active subscription ### Generator Tools URL: https://vektorai.io/features/generators 8 tools for SEO, AEO, and GEO optimization: 1. **llms.txt Generator** — Creates a structured llms.txt file for AI crawler discoverability 2. **JSON-LD Schema Generator** — Auto-generates FAQPage, Organization, Article, BreadcrumbList, and WebSite structured data 3. **robots.txt Generator** — Creates robots.txt with proper AI bot directives (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) 4. **Sitemap.xml Generator** — Crawls your site and generates a valid XML sitemap 5. **OG / Meta Tag Generator** — Generate and preview Open Graph and Twitter Card meta tags 6. **Favicon & Manifest Builder** — Create favicon assets and web app manifest for PWA support 7. **Heading Analyzer** — Visualize heading hierarchy (H1-H6) and flag structural issues 8. **Page Speed Checker** — Core Web Vitals lookup via Google PageSpeed Insights API --- ## Scoring System VektorAI produces four independent scores from 0 to 100.

Score Calculation: Score = (Weighted Passes / Total Weighted Checks) x 100 Severity Weights: - Critical: 3x weight - Warning: 2x weight - Info: 1x weight Score Ranges: - 90-100: Excellent — minimal issues - 70-89: Good — some improvements needed - 50-69: Needs Work — significant gaps - 0-49: Critical — major issues affecting visibility --- ## Pricing | Plan | Price | Features | |------|-------|----------| | Free | $0 | Basic audits with limited results | | Single Report | $9 one-time | Full audit report for one URL with PDF download | | Pro | $39/month | Unlimited audits, AI Fix, monitors, compare, generators, PDF reports | --- ## Technology Stack - Frontend: Next.js App Router, TypeScript, Tailwind CSS - AI Fix: WebLLM (@mlc-ai/web-llm) for in-browser inference via WebGPU - Database: Prisma ORM - Authentication: NextAuth.js - Payment: Whop SDK for subscription management - Audit Engine: Server-side HTML parsing with linkedom, PageSpeed Insights API for performance data --- ## Educational Content ### AI Citation Tracking Documentation URL: https://vektorai.io/docs/citations Complete guide to the AI Citation Tracking feature: - Setting up a tracker with domain and keywords - Understanding the Visibility Score (0-100 composite of citation rate, position quality, and AI answer mention rate) - Interpreting keyword results: citation status, position, competitors, AI answer mentions - Managing trackers: add/remove keywords, pause/resume, change domain - Limits: 1 tracker per Pro user, up to 10 keywords, weekly automated checks - Tips for choosing effective keywords and improving citation rates ### What is SEO?
