What Vexifa SEO Does
AI Audit Engine
Up to 14 Parallel AI Agents
The Full Audit runs 5 always-on specialist agents (Technical, On-Page, Content, Schema, Images) plus up to 9 conditional agents that activate on detected signals — Local SEO, E-commerce, Hreflang, CWV, JavaScript, Entities, Snippets, Links, and Architecture.
Drift Monitoring
Capture a baseline for any URL and monitor 25 on-page signals for change — noindex status, canonical, title, meta description, H1, word count, performance score, og:title, og:image, H2 count, internal links, render-blocking scripts, schema types, and more.
Visual SEO — 3-Viewport Screenshots
Captures mobile (390px), tablet (768px), and desktop (1280px) screenshots in parallel and passes all three to your AI model for layout analysis, CTA visibility, responsive design, and CLS risk assessment.
Local File Audit
Point Vexifa at a local folder or individual HTML file and audit a site before it goes live. Supports up to 5 HTML files per folder — no public URL required, no live server needed.
Integrations & Real Data
Google Search Console
Connect via OAuth 2.0. Real clicks, impressions, CTR, and ranking positions are injected directly into audits as context — ranking opportunities (high impressions, low CTR) surfaced automatically.
Google Analytics 4
Reuses your Search Console OAuth credentials. Surfaces sessions, bounce rate, and session duration per page — giving audits real engagement context alongside ranking data.
Backlink Authority Data
Connect Moz (free tier), Ahrefs, or DataForSEO — or use the free Bing link scraper. All sources are merged with weighted confidence scoring: Domain Authority, Domain Rating, referring domains, spam score.
PageSpeed & Core Web Vitals
Real LCP, CLS, INP, and FCP field data from Google's CrUX dataset and PageSpeed API. An optional API key raises the daily quota from the public limit to 25,000 requests.
23 Specialist Skills
Technical & On-Page
Crawlability, indexability, Core Web Vitals, JavaScript rendering, title and meta tags, heading structure, internal linking, content quality, and image optimization — all in a single unified report.
Content, E-E-A-T & Schema
Content quality and expertise signals, JSON-LD extraction and validation, rich result eligibility, and entity coverage. Separate skills for Local SEO, E-commerce, and International (Hreflang).
GEO / AI Visibility
Generative Engine Optimization audit for ChatGPT, Perplexity, and Google AI Overviews — assesses whether your content is structured to be cited in AI-generated answers.
Accessibility, Entity, Snippet & Architecture
WCAG-SEO overlap, Knowledge Panel eligibility, snippet targeting for paragraph/list/table formats, and site architecture analysis covering URL depth, crawl efficiency, and orphan risk.
Bulk Audits & History
Bulk URL Auditing
Paste a list of URLs, select a skill, and Vexifa audits them sequentially — saving every result to history automatically. Progress shown in real time with a per-URL counter.
Audit History
Every audit is stored locally as a JSON file with the full markdown result, skill, provider, model, and timestamp. Load, re-run, delete, or promote any audit to a drift monitoring baseline.
Export to PDF & Markdown
Export audit results to PDF via the browser print dialog, or export drift monitoring reports as Markdown files for documentation, change logs, or client deliverables.
Competitor Analysis
The Competitor Analysis skill runs your site and a competitor URL in parallel, generates individual reports, then synthesizes a gap analysis — content opportunities, vulnerabilities, and an action matrix.
Site Crawler
Full-Site Crawler
Crawl an entire domain — discovering pages via sitemap seeding and recursive link following. Captures title, meta description, H1, canonical, noindex, status codes, internal links, schema types, and more for every page.
JS Rendering Mode
Switch the crawler to headless browser mode for SPAs, Next.js, and React sites where content is loaded client-side. Configurable render timeout and wait time — use HTTP mode for static sites, JS mode when you need it.
Crawl Comparison
Compare any two saved crawls side by side. Vexifa surfaces new issues, resolved issues, and changed values per page — so you can prove the impact of a migration, CMS update, or technical fix.
Scheduled Crawls
Set a weekly or monthly recrawl schedule for any saved site. Vexifa registers a Windows Task Scheduler job — the crawl runs automatically and triggers a crawl comparison against the previous run.
Keyword Rank Tracking
Keyword Rank Tracker
Track keyword positions over time using SerpApi or Zenserp. Each tracked keyword stores a position history and sparkline — see rank trends without exporting to a spreadsheet or paying for a dedicated rank tracker SaaS.
Automated Rank Alerts
Vexifa checks all tracked keywords on launch and fires a native Windows notification when any keyword moves more than your configured threshold — so ranking drops are caught immediately, not on your next manual check.
GSC Position Cross-Validation
Google Search Console position data is pulled alongside SERP API rank data. Compare GSC average position against real SERP rank for the same keyword — ground-truth validation without spending additional API credits.
Content Gap Analysis
Run a post-crawl NLP pass against a competitor crawl to surface topics they rank for that your site doesn't cover. Results are fed into the Competitor Analysis skill as structured context for AI-generated content recommendations.
Agency & Multi-Site Tools
Multi-Site Dashboard
One view across all your client sites — issue count trend, last crawl date, drift status, and top keyword position per site. Click any card to deep-link into the Crawler or Keywords tab filtered to that domain.
White-Label HTML Reports
Generate a self-contained branded HTML report from any audit or crawl — cover page with client logo and agency name, structured sections (Executive Summary, Technical, On-Page, Backlinks, Recommendations), page-numbered footer. Opens in any browser for print-to-PDF.
Bring Your Own API Key — No Markup
Every integration connects directly to the provider at cost: Anthropic, OpenRouter, Moz, Ahrefs, DataForSEO, SerpApi, Google PSI, GSC, and GA4. No Vexifa servers in the data path — you pay provider rates, not a SaaS premium.
MSIX Installer — Windows 10 & 11
Distributed as a signed MSIX package for clean Windows 10 and 11 installation. No runtime dependencies, no Java, no Electron overhead — a native Rust/Tauri binary that starts in under a second.
What Your Current Platform Won't Give You
SaaS SEO platforms either don't offer these capabilities or lock them behind expensive plans and credits. Vexifa SEO ships every one of them — included.
Up to 14 AI Agents in Parallel
IncludedSaaS tools run sequential analyses. Vexifa fires up to 14 specialist agents simultaneously — Technical, On-Page, Content, Schema, Images, and up to 9 conditional agents all running at the same time via true parallel execution.
GEO / AI Visibility Audit
IncludedMost SaaS SEO platforms have no generative engine optimization audit. Vexifa's GEO skill assesses whether your content is structured to be cited by AI answer engines like ChatGPT, Perplexity, and Google AI Overviews.
Drift Monitoring — 25 Signals
IncludedCapture a snapshot of any URL and Vexifa alerts you when any of 25 on-page signals change — noindex status, canonical, title, meta description, H1, Core Web Vitals, schema types, og:image, and more.
Audit Local Files Before Launch
IncludedNo cloud tool can audit HTML files sitting on your hard drive. Vexifa audits a local folder or HTML file before it goes live — fix SEO issues before they ever hit a server or Google's index.
True Data Privacy — 100% Local
IncludedEvery audit result, API key, and history item is stored on your machine. Nothing is sent to Vexifa's servers. Your client data never touches a shared cloud database.
3-Viewport Visual SEO Screenshots
IncludedCaptures mobile, tablet, and desktop screenshots in parallel and passes all three to your AI model for visual analysis. SaaS tools analyze HTML — Vexifa analyzes what users actually see.
Bring Your Own API Key — No Markup
IncludedSaaS SEO platforms resell AI and data APIs at a significant markup inside their subscription. Vexifa connects directly to your configured AI provider (Anthropic, OpenRouter, or others) and to backlink data sources (Moz, Ahrefs, DataForSEO) at cost — you pay the provider rate, not a SaaS premium.
Free AI via Local Ollama
IncludedSaaS platforms' built-in AI tools are credit-gated and metered. Vexifa runs local models via Ollama for unlimited, offline AI audits at zero API cost.
Google Search Console + GA4
IncludedNative OAuth connections to GSC and GA4. Real impressions, clicks, CTR, positions, sessions, and engagement data are injected directly into audits as context — no third-party plugin or CSV export required.
Full-Site Crawler with JS Rendering
IncludedThe market-leading desktop crawler is Java-based and charges per seat. Vexifa's Rust crawler runs natively with zero overhead — and its headless browser mode captures JS-rendered content from SPAs and React apps that HTTP-only crawlers miss entirely.
Automated Rank Drop Alerts
IncludedSaaS SEO platforms send weekly digest emails. Vexifa fires a native Windows OS notification the moment any tracked keyword drops more than your configured threshold — rank changes caught the day they happen, not seven days later.
White-Label Client Reports
IncludedAgencyAnalytics charges $12–$18 per client per month for white-label reporting. Vexifa generates branded, self-contained HTML reports — your logo, your agency name, structured sections, and page numbers — at no additional cost per client or report.
