Metrics & Audits
A plain-English glossary of everything our audit actually checks and scores. Every check below is a real part of the report — no vanity metrics, no filler.
When you run an audit, SEO AI Audits crawls up to 500 pages and scores your site across 26 factors, 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
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
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
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
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
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
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
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 measure whether answer engines and AI assistants can find, trust, and quote your content.
AEO
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 measures how citable and identifiable your brand is to tools like ChatGPT, Perplexity, and Google AI Overviews. It reads your Organization schema and sameAs profiles to judge whether an assistant can resolve you to a known entity before it decides what to say.
AIO
AI optimization is about machine-readability for LLM crawlers: whether your content is well-structured and served without heavy JavaScript rendering, whether AI bots are blocked, and whether an emerging /llms.txt file declares how your content should be used.
Trust & quality
Signals that separate a credible, well-maintained site from a thin one — the things both Google and AI assistants weigh before trusting a source.
E-E-A-T
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
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
Compares pages across the crawl to find exact and near-duplicate content that can split ranking signals or waste crawl budget.
Semantic HTML
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
Validates the structured data (JSON-LD) on your pages so search engines and AI can understand what each page represents and are eligible for rich results.
Social
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
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.
