Free SEO Audit Tool by DeepAudit AI
What the free SEO audit checks
DeepAudit AI is a free SEO audit tool that scans your website in a real Chromium browser, the same way Google renders pages, then runs 100-plus checks across 15 categories: Meta Tags, Headings, Images, Links, Performance, Keywords, Open Graph and Social, Structured Data, Technical, Content, Security Headers, Accessibility, Site-Wide Health, AI Readiness, and Local SEO. Every check returns a pass, warning, or fail with a copy-paste fix.
How the SEO audit works
Paste your URL and run the audit free, with no signup and no credit card. DeepAudit AI loads your page in a real browser, measures Core Web Vitals and Lighthouse scores, deep scans up to 50 pages from your sitemap, and checks keyword demand against Google Autocomplete. AI then rewrites your title tag and meta description and hands you a prioritized action plan ranked by revenue impact, plus a downloadable PDF report.
Why a real browser SEO audit beats HTML-only checkers
Most free SEO checkers parse raw HTML and miss everything your site renders with JavaScript. Google does not. DeepAudit AI works as a true JavaScript SEO scanner, rendering each page the way Googlebot does, so it catches the Core Web Vitals audit failures, client-rendered content, and missing tags that HTML-only tools report as passing.
Free SEO audit FAQ
How is DeepAudit AI different from other SEO tools?
Most free tools parse raw HTML. DeepAudit AI renders your page in a real Chromium browser (like Google does), runs 100+ checks across 15 categories including AI Readiness and Local SEO, deep scans up to 50 pages from your sitemap, checks keywords against Google Autocomplete for real search demand, analyzes competitor rankings with Google Trends data, identifies content gaps, and generates specific copy-paste fixes. AI rewrites your title tag and meta description, and provides a prioritized action plan ranked by revenue impact.
What does the AI actually do?
The scoring engine runs 100+ deterministic checks and computes a weighted score across 9 categories. Then AI analyzes those results alongside Google Lighthouse scores, multi-page crawl data, keyword demand signals, and competitor data to rewrite your title tag and meta description for better CTR, and generate a prioritized action plan ranked by revenue impact.

Yes, completely free. 3 full audits per day with no signup, no credit card, and no hidden fees. Each audit includes Google Lighthouse data, 100+ checks, multi-page crawl, AI-written title and meta description, and a downloadable PDF report.
What does DeepAudit AI check?
DeepAudit AI checks 15 categories: Meta Tags, Headings, Images, Links, Performance, Keywords, Open Graph and Social, Structured Data, Technical, Content, Security Headers, Accessibility (WCAG), Site-Wide Health, AI Readiness, and Local SEO. Each category contains multiple checks with pass, warning, or fail status and specific fix recommendations.
What is the Deep Scan feature?
Deep Scan crawls up to 50 pages from your sitemap or homepage links and runs SEO checks on each page individually. It identifies thin content, missing meta descriptions, duplicate H1 tags, broken canonical URLs, and other per-page issues across your entire site. Deep Scan runs in the background and takes 2-3 minutes to complete.
What are the AI Readiness checks?
AI Readiness checks whether your site is optimized for AI assistants like ChatGPT, Perplexity, and Claude. It verifies the presence and quality of llms.txt and llms-full.txt files, checks if robots.txt blocks AI crawlers, and evaluates your structured data for AI extraction. As AI-powered search grows, these checks ensure your business appears in AI-generated answers.
What are the Local SEO checks?
Local SEO checks evaluate your site for local search visibility: LocalBusiness schema markup with address, phone, and hours; NAP (Name, Address, Phone) visibility in page content; Google Maps or Google Business Profile links; and geographic meta tags. These are critical for businesses serving specific geographic areas.
