When you run an audit, SEO AI Audits crawls up to 600 pages and scores your site across 28 modules, grouped into the categories below. Each one earns its own grade, and every issue comes with a plain-language explanation and a fix. This page explains what each metric measures — so a grade in your report is never a mystery.

Core SEO

The fundamentals every search engine reads first — how your pages are built, how they are written, and whether the content is substantial enough to rank.

Technical

Crawlability & indexing

Checks the machinery search engines rely on: robots.txt and sitemap coverage, canonical tags, indexability, redirects, HTTPS, hreflang and pagination, and clean URL structure across every crawled page.

On-Page

Titles, meta & headings

Evaluates the elements you control on each page — title tags and meta descriptions (length and uniqueness), a single well-formed H1, heading hierarchy, and image alt text.

Content

Depth & readability

Looks at whether pages carry enough substantive text to rank, the ratio of real content to markup, and how readable that writing is for a general audience.

Performance & Security

How fast the page feels to a real visitor, whether everyone can use it, and whether it is served safely.

Performance

Core Web Vitals

Measures real-world speed using Core Web Vitals — largest contentful paint, layout shift, and interactivity — alongside page weight and load time, so you see what actually slows visitors down.

Security

Passive, read-only checks

A passive, no-touch review of HTTPS enforcement, HSTS, the Content-Security-Policy and other security headers, mixed content, and email records like SPF and DMARC. We never probe or attack a site.

Accessibility

a11y basics

Flags common barriers that also hurt SEO — missing image alt text, unlabeled form fields, poor heading order, and language attributes — so your pages work for more people and more crawlers.

Mobile

Mobile-friendliness

Confirms the essentials of a mobile-ready page, starting with a correct viewport meta tag and touch-friendly layout signals, since Google indexes the mobile version first.

AI-era readiness — AEO, GEO, AIO

Search is no longer only ten blue links. These three checks read the on-page signals that let an answer engine or AI assistant reach your content, parse it, and lift a clean answer from it. They are a structural read of your pages, not a live query of what any AI engine says about you today.

AEO

Answer Engine Optimization

Answer-engine optimization asks whether a machine could lift a clean, self-contained answer from your page for featured snippets, People Also Ask, and AI Overviews. We look at the text that actually follows each question-style heading — not just whether the question exists.

GEO

Generative Engine Optimization

Generative-engine optimization reads the markup that identifies the organization behind your site — Organization schema, the sameAs links to your official profiles, author signals and modified dates — plus how concrete the writing is (named figures, dates, outbound sources). No AI engine documents sameAs or a Wikipedia entry as a citation factor; what unambiguous entity markup reliably does is let anything parsing the page tell which organization it is reading about.

AIO

AI Optimization

AI optimization is about machine-readability for LLM crawlers: whether your content is well-structured and served without heavy JavaScript rendering, and whether AI crawlers are blocked in your robots.txt. Two things we report but never score — whether an /llms.txt file exists, an optional index of your own key pages that no major AI search engine has committed to reading, and any Content-Signal line in robots.txt, which is where you state how you want your content used.

Trust & quality

Signals that separate a credible, well-maintained site from a thin one — bylines and dates, clean markup, and pages that are not near-duplicates of each other. We score them as site-quality hygiene: Google says E-E-A-T itself is not a specific ranking factor, and no AI engine documents these as citation factors.

E-E-A-T

Experience, Expertise, Authoritativeness, Trust

Scores the trust signals Google associates with quality content — author bylines and credentials, about and contact pages, outbound links to authoritative sources, and Person or Organization schema.

Freshness

Content age

Detects published and modified dates across your pages to gauge how current your content is, since stale pages lose ground in fast-moving topics.

Duplicate content

Near-duplicate detection

Compares pages across the crawl to find exact and near-duplicate content that can split ranking signals or waste crawl budget.

Semantic HTML

Markup quality

Checks whether pages use meaningful HTML5 elements — header, nav, main, article, section, footer — rather than a wall of generic divs, which helps both assistive tech and machine parsing.

Schema

Structured data

Validates the structured data (JSON-LD) on your pages — the types present, the fields Google requires for each, and the values that make a block invalid — so a machine can tell what each page represents. Types Google still shows a rich result for (Article, Product, Local business, Breadcrumb, Event, Recipe) are checked against its requirements; FAQPage and HowTo are flagged instead, since Google removed those rich results from Search in May 2026.

Social

Open Graph & sharing

Reviews the Open Graph and social meta tags that control how your pages look when shared, plus linked social profiles that reinforce your brand entity.

Local

NAP & LocalBusiness schema

For sites that look like a local business, audits name-address-phone consistency, LocalBusiness schema, maps, and opening hours. Sites with no physical presence are scored neutrally, never penalized.
