From URL to fixes in 30s to a few minutes
No sign-up. No fluff. Lighthouse + 18 verified sources, AI-explained fixes, copy-paste code. Timing depends on site complexity.
We run our engine on ourselves. Updated weekly.
Everything your site needs. Done in minutes.
Scanora cross-checks your site against 18 verified data sources — Lighthouse, axe-core, SSL Labs, Mozilla Observatory, Safe Browsing, W3C, Carbon, Wappalyzer tech detection, DNS health, and Wayback domain age (10 third-party); plus our in-house content-SEO, schema.org, robots/sitemap, image weight/format, and internal-link graph parsers (5 in-house); plus three in-process probes that run during every audit — JS-shell detection, rendered-meta extraction, and TLS certificate-chain inspection (3 in-process). Every finding is then run through AI for a plain-language fix.
How the AI works — 3 steps
Scan
We fan out 18 parallel checks: Lighthouse (5-run PSI median + CrUX), axe-core for WCAG 2.1 AA, Mozilla Observatory for security headers, SSL Labs for TLS, Safe Browsing for malware, W3C for HTML, Website Carbon for sustainability, Wappalyzer tech-stack fingerprinting, DNS health, Wayback domain age, plus in-house content-SEO, schema.org, robots/sitemap, image weight/format, internal-link graph, JS-shell detection, rendered-meta extraction, and TLS cert chain.
Analyse
Our engine merges the raw results from all 18 evidence sources, cross-references 60+ issue patterns, dedupes, and ranks every problem by its real-world impact on SEO, speed, security, and conversions.
Fix
Every issue gets a plain-language AI explanation (Gemini 2.5 Flash, with GPT-4o Mini as fallback) plus a copy-paste code fix tailored to your detected stack. Implement yourself or hire us for a managed rebuild.
18 verified data sources — cross-checked every scan
Every audit row links back to the source provider so you can verify the result independently — see the “Verified by” panel on every report.
Performance · SEO · A11y · Best Practices — diagnostic engine; Core Web Vitals from CrUX are the actual ranking signal
WCAG 2.1 AA accessibility audit — industry-standard a11y engine. Runs on the static (server-rendered) DOM, so JavaScript-rendered ARIA states and dynamic widgets need a manual pass with browser axe DevTools.
Security headers grade (CSP, HSTS, X-Frame-Options, Referrer-Policy, more)
TLS / certificate grade — chain validity, protocol versions, cipher strength
Live malware and phishing screen — same list Chrome uses
HTML standards compliance — markup errors and warnings flagged
Sustainability score — page weight and grid carbon estimate
Wappalyzer-powered: 3,000+ technology fingerprints (CMS, frameworks, analytics, CDN, more). Detected via HTTP probe — JavaScript-rendered or dynamically loaded technologies may not be visible.
Live DoH lookup (Cloudflare/Google) for SPF, DMARC, MX, CAA, AAAA records — sending-domain verifiability and email deliverability signals
archive.org CDX — domain age (first-archive date) and change cadence as a trust signal; flags brand-new and stale-archive domains
In-house: thin content, heading hierarchy, anchor-text quality, multiple-H1 detection
In-house: JSON-LD extraction with required-property checks across 17 schema types
In-house: crawl-delay, sitemap freshness, mixed-protocol detection, sitemap-index descent, 10-URL HEAD sample
In-house HTML parser: CLS risk from missing width/height, lazy-load coverage on positions 4+, modern-format opportunity (WebP/AVIF), fetchpriority misuse
In-house: link map from audited pages — orphan detection, shallow-link pages, hub-page identification (depth scales with crawl mode)
What we analyse in every scan
Meta tags, canonicals, Open Graph, schema.org, robots.txt, sitemap, hreflang, duplicate titles
LCP, CLS, INP/FID, FCP, TTFB — CrUX p75 field data + 5-run PSI lab median
Viewport config, touch target sizing, font legibility, horizontal scroll, tap spacing
Headers (Mozilla Observatory), certificate / chain (SSL Labs), HSTS, CSP, malware screen
axe-core 2.1 AA — contrast, alt coverage, ARIA, keyboard nav, focus indicators, form labels
Render-blocking JS, unused CSS/JS, third-party blocking time, W3C HTML validation
Oversized images, missing width/height, lazy-load status, WebP/AVIF, LCP element ID
Website Carbon score, page weight, grid CO₂ estimate, full tech-stack fingerprint
Simple sites complete in ~30 seconds · Complex or JS-heavy sites may take up to 5 minutes · Live progress shown throughout
Automated Troubleshooting
Scanora cross-checks every layer of your site against 18 verified data sources — HTML, CSS, JS, server headers, certificates, accessibility, malware screens, schema, and crawl/index signals — then ranks every issue by its real-world impact on rankings and conversions.
- 18 verified data sources, run in parallel
- Detects 60+ issue categories per scan
- AI-explained fixes with copy-paste code
Performance Optimisation
Powered by Google PageSpeed Insights — Lighthouse diagnostics plus CrUX field data (real Chrome users, last 28 days) for LCP, CLS, and INP when available. Core Web Vitals and page experience can influence search performance; Lighthouse scores themselves are diagnostic, not direct ranking signals. We take the median of 5 independent PSI runs per device for stability.
- 5-run Lighthouse median — eliminates variance
- CrUX real-user field data vs lab comparison
- LCP element identified: tag, src, size, lazy status
AI-Explained Fixes
Every issue surfaced from the 18 evidence sources is run through Gemini 2.5 Flash (with GPT-4o Mini as fallback) for a plain-language explanation, an impact estimate, and a copy-paste code fix tailored to your stack — clearly labelled "AI-explained" so you always know what was measured and what is reasoning.
- Gemini 2.5 Flash (GPT-4o Mini fallback) per issue
- Plain-language "why this matters" for every fix
- Copy-paste code tailored to your detected stack

Instant AI Fixes You Can Apply Today
Many critical issues can be fixed in minutes using our AI guidance — no rebuild needed.
Add Meta Description
Add this inside your <head> tag. Keep it under 160 characters. Include your primary keyword naturally.
→ Boosts CTR by 5–15% in search results
Add Viewport Meta Tag
Add this inside your <head> tag. This single line makes your site mobile-friendly and prevents Google demotion.
→ Fixes mobile rendering for 60%+ of traffic
Add JSON-LD Schema
Add before </body>. Replace values with your real info. This enables rich results in Google Search.
→ Unlocks rich snippets — star ratings, FAQs, breadcrumbs
Lazy Load Images
Add loading="lazy" to all images except your hero. This defers off-screen images and dramatically improves LCP.
→ Reduces initial page load by 40–60%
Fix Missing Alt Text
Every content image needs descriptive alt text. Decorative images use alt="". This fixes accessibility and helps Google understand your images.
→ Improves accessibility score + image search ranking
Defer Render-Blocking JS
Add defer to all non-critical scripts. This lets the browser render your page before executing JavaScript — huge LCP improvement.
→ Reduces TBT by 200–800ms on average
Add Canonical URL
Add the canonical tag pointing to the preferred URL of each page. Prevents duplicate content penalties and consolidates ranking signals.
→ Prevents duplicate content penalties
Fix Color Contrast
Use a contrast checker (WebAIM or browser DevTools) to find failing text. Aim for 4.5:1 for body text, 3:1 for large text.
→ Fixes WCAG AA compliance + improves readability
