Everything you get — explained
A complete SEO platform, 100% free
SEO AI Audits bundles a 26-point audit, an AI assistant, AI-search visibility, and 40 standalone tools into one place — with no signup and no credit card. Here’s exactly what each feature does and what you get.
The complete SEO audit
26 analysis modules across 9 dimensions — every weakness found, ranked by impact, with a plain-English fix.
Technical SEO
The crawlability and indexability foundation everything else is built on. We check whether search engines can actually reach, render, and index your pages — the issues that silently cap a whole site.
- HTTPS & SSL validation
- XML sitemap & robots.txt analysis
- Canonical tags & duplicate handling
- Redirect chains & loops
- Crawl depth & orphan-page detection
On-Page SEO
Page-by-page analysis of the elements you control directly. We flag every weak title, missing meta description, and broken heading hierarchy across up to 500 pages — with the exact fix for each.
- Title tags & length scoring
- Meta descriptions & duplicates
- Heading structure (H1–H6)
- Keyword usage & TF-IDF
- Image alt text coverage
Performance & Core Web Vitals
Real-user Core Web Vitals from the Chrome UX Report — the p75 LCP, INP and CLS Google actually ranks on — alongside the lab data and a JavaScript render-budget breakdown that shows what is slowing the page down.
- Real-user field data (CrUX p75) + pass/fail
- Lab vs field comparison
- LCP, INP, CLS, FCP, TBT, TTFB
- JS render budget & unused JavaScript
- Third-party blocking & page weight
Security & Trust
The security headers and HTTPS configuration that build trust with both users and search engines. Missing headers won’t tank you overnight, but a secure, modern setup is a genuine trust signal.
- HSTS, CSP, X-Frame-Options
- Mixed-content detection
- HTTPS enforcement per page
- Referrer & permissions policies
Accessibility
Accessibility and SEO overlap heavily — both reward clean, semantic, usable pages. We surface the WCAG signals that also help search engines understand your content.
- Color-contrast checks
- Alt text & ARIA
- Form labels & link names
- Heading order & landmarks
- Tap-target sizing (mobile)
Content Quality
Is your content thin, duplicated, or genuinely useful? We measure readability, detect duplicate and near-duplicate pages, and map how link equity flows through your site.
- Readability scoring
- Thin-content detection
- Exact & near-duplicate content
- Internal link equity (PageRank)
- Broken-link & anchor analysis
AEO — Answer Engine Optimization
Optimizing to win featured snippets and answer boxes. We check whether your pages are structured to be the concise, direct answer that answer engines lift to the top.
- FAQ & HowTo schema readiness
- Concise-answer formatting
- Question-based heading coverage
- Featured-snippet eligibility
GEO — Generative Engine Optimization
How likely AI search (ChatGPT, Perplexity, Google AI Overviews) is to cite you. We assess the E-E-A-T and citation signals generative engines rely on when choosing sources.
- E-E-A-T signal analysis
- Author & citation signals
- Entity & authority clarity
- Quotability assessment
AIO — AI Optimization
Whether your site is machine-readable for large language models. We check the structural and metadata signals that let AI crawlers parse, chunk, and reuse your content.
- llms.txt presence
- Semantic HTML structure
- Structured data (schema.org)
- Machine-readable metadata
- What AI crawlers see (JS-render diff)
Plus dedicated modules for E-E-A-T, content freshness, duplicate content, semantic HTML, anchor text, schema, mobile, hreflang, and more.
BUILT FOR THE AI ERA
AI features other audit tools don’t have
Don’t just find problems — understand them, fix them, and get visible to AI search.
AI Action Plan
Every audit ends with an AI-generated, prioritized to-do list written in plain English — grouped into critical fixes, high-impact improvements, and quick wins. It reads your actual results and tells you what to do first, and why it matters. No SEO jargon, no guessing where to start.
AI Assistant (chat)
Ask anything about your audit — “what should I fix first?”, “how do I improve my Core Web Vitals?”, “why is this page flagged?” — and get specific, data-backed answers grounded in your real results. It turns a wall of issues into a conversation.
AI Visibility Report
See how AI assistants perceive your brand: a visibility score, whether AI recognizes you, which competitors it favors in your category, the prompts you do (and don’t) show up for, and a concrete plan to improve. This is the on-trend metric most tools don’t measure at all.
NLP Content Analyzer
Reads any page the way a search engine does — extracting its primary topic, search intent, entities, and target keywords, then surfacing the content gaps you should fill to deepen topical relevance. It tells you not just what you cover, but what you’re missing.
AI Retrieval & AAIO Readiness
Scores how easily AI search can find, chunk, understand, and cite your page — with pass/fail checks on chunkable structure, direct answers, factual density, and machine-readability, plus fixes. Optimizing for the AI-search era, made concrete.
AI Bot Access Check
Confirms the crawlers behind ChatGPT, Perplexity, Claude and Google AI Overviews can actually reach your site — evaluating robots.txt per bot and sending live requests to catch the CDN/WAF 403 blocks that silently make you invisible to AI search. Also available as a standalone free tool.
