Free SEO Audit Tool — Analyze Your Website Instantly with AI

What Our SEO Analyzer Covers
Our AI-powered SEO tool crawls your website in real time and evaluates every dimension of your SEO health. Whether you're a business owner, marketer, or agency, our audit gives you a prioritized list of fixes with estimated impact so you know exactly where to focus first.
Technical SEO Audit
We check your title tags, meta descriptions, canonical tags, structured data (schema.org), Open Graph tags, header hierarchy, and robots directives. Technical SEO issues can prevent search engines from properly indexing your pages — our tool identifies and prioritizes them instantly.
On-Page Content Analysis
Content is king for SEO. Our analyzer evaluates your word count, keyword usage, heading structure (H1, H2, H3), image alt text, and internal linking. We identify thin content, missing meta tags, and opportunities to improve your content for better search rankings.
Page Speed & Performance
Page speed is a confirmed Google ranking factor. Our tool assesses your website's performance, including image optimization, resource compression, browser caching, and Core Web Vitals. Get specific recommendations to improve load times and user experience.
Mobile Optimization
With mobile-first indexing, Google uses the mobile version of your site for ranking. Our audit checks viewport configuration, responsive design, tap target sizes, and mobile-friendliness to ensure your site performs well on all devices.
Backlinks & Domain Authority
Backlinks remain one of the strongest ranking signals. Our tool assesses your backlink profile, domain authority signals, and external link strategy to help you understand where you stand and how to build authority over time.
