Every other "devil" in SEO is the one punishing you — Google's algorithm, a manual penalty, a competitor outranking you. SEODevil flips the script: the only devil that's actually working for you, hunting down every issue before Google finds it and handing you the fix.
One audit, eleven angles. SEODevil doesn't just find problems — it tells you exactly what to fix, in what order, for your specific platform.
Submit any URL and get a full technical SEO report instantly. No browser extension, no Chrome DevTools juggling — just results.
Get a 30-day prioritized task list tailored to your platform — WordPress, Shopify, Next.js, and more.
Auto-generated PDF with severity charts, code examples, and issue breakdowns. Client-ready in one click.
Scans for HTTPS enforcement, mixed content, HSTS, CSP, X-Frame-Options and all critical security headers.
Each audit produces a 0–100 score. Severity-weighted deductions (critical, high, medium, low) give an honest picture.
Detects JSON-LD, Microdata, and RDFa. Flags missing schema for articles, products, reviews, and local business — the schema Google rewards.
Plus auto-fix for WordPress and GitHub, AI fix code, AI search visibility, monitoring and Search Console impact. See all features
Paste any page URL. SEODevil fetches the page, all headers, robots.txt, and sitemap simultaneously.
