01How the site audit works
Your homepage, a landing page or a competitor's site. No code access, DNS records or tracking script needed.
The engine fetches the page, robots.txt, sitemap and llms.txt, then runs every check at once instead of one tool at a time.
Issues are ranked by severity and module weight, each with a plain-English fix and, where it helps, the exact code to paste.
02What's in the report
18 modules and 150+ checks run in parallel against your live page. The free report and the full dashboard use the same engine — here is exactly what it looks at.
Can search engines reach, render and index the page?
Finds anything that keeps a page out of the index: noindex tags, robots.txt blocks, canonical conflicts, error status codes and content that only appears after JavaScript runs.
Checks include
Checks the plumbing: HTTPS, redirect chains, server response time, compression, URL hygiene and the head tags every crawler expects.
Checks include
Validates the XML sitemap and maps your internal link graph to surface orphan pages, deep click paths and duplicate or near-duplicate pages.
Checks include
Reviews the response headers that protect visitors and signal a well-run site, plus mixed content and version leaks.
Checks include
Validates hreflang for multi-language and multi-region sites so the right version ranks in the right country.
Checks include
Compares each scan with the previous one and flags regressions — the changes that quietly break rankings after a deploy.
Checks include
Does the page say clearly what it is about, and prove it?
Grades the elements that tell Google what a page is about: title, meta description, headings, social tags and topic alignment.
Checks include
Looks for depth, readability and trust signals — authorship, dates and structure — that separate helpful pages from thin ones.
Checks include
Tests internal and external links for breakage and quality so link equity flows where it should.
Checks include
Audits how the page passes and earns authority: anchor text mix, outbound citations and malformed or redundant links.
Checks include
Checks every image for alt text, modern formats, dimensions and loading strategy — including the LCP hero image.
Checks include
Is it fast, stable and usable on every device?
Inspects what slows a page down before it ever reaches a user: render-blocking resources, DOM and HTML weight, fonts, resource hints and third-party scripts.
Checks include
Runs Google PageSpeed Insights for mobile and desktop and brings Core Web Vitals, the Lighthouse score and its opportunities into your report.
Checks include
Simulates mobile viewports to catch zoom blocking, tiny text, small tap targets and horizontal scrolling.
Checks include
Checks the fundamentals of WCAG: labels, alt text, landmarks, keyboard order and document language.
Checks include
Search experience optimization: does the landing experience match search intent and give visitors a reason to act and trust you?
Checks include
Can ChatGPT, Gemini and Perplexity crawl, understand and cite it?
Checks whether AI search engines can crawl, understand and quote your page: AI crawler access, llms.txt, fact density, Q&A structure and entity signals.
Checks include
Validates JSON-LD structured data, flags types Google no longer shows as rich results, and suggests schema the page is missing.
Checks include
Weighted, not averaged. Each module scores 0–100 from the severity of its issues, then rolls up by importance.
×3 – ×2
Ranking-critical
Indexability, technical SEO, on-page, content and performance. One failure here can keep a page out of results.
×1.5 – ×1.25
Strong signals
Schema, mobile UX, links, AI visibility, sitemap and security — rich results, experience and trust.
×1 – ×0.75
Quality & polish
Images, accessibility, international, SXO, link equity and drift monitoring.
03Beyond the score
Most audit tools stop at a number. Every issue here comes with why it matters, where it is, and how to fix it — then tracks whether the fix held.
Each issue explains the impact in plain English and, for technical fixes, gives you the exact markup, header or robots.txt rule to ship. Re-check a single module for 0.5 credits once it's live.

A website audit report is a scored checklist of everything that affects how a site ranks and converts: crawlability and indexing, on-page SEO, content quality, Core Web Vitals, structured data, security headers, accessibility and, increasingly, how AI search engines read the page. Site Audit Score runs 18 modules and turns the results into one report with every issue ranked by impact and a recommended fix.
Yes. The quick report on this page needs no signup: enter a URL and you get an overall score, category scores and the top fixes. Creating a free account adds 100 credits, the full issue list with code-level fixes, PageSpeed Insights results and multi-page crawling. No credit card is required.
The AI & GEO module checks whether AI search engines can reach and quote your page: robots.txt rules for 12 AI crawlers (including OAI-SearchBot, GPTBot, ClaudeBot, PerplexityBot and Google-Extended), an llms.txt file, fact and statistic density, question-style headings, E-E-A-T signals, and Organization and FAQPage schema.
Each module scores 0–100 based on the severity of the issues it finds. The overall score is a weighted average: ranking-critical modules such as Indexability and Technical SEO count three times as much as polish checks, so one noindex tag moves the score far more than a missing alt attribute.
Yes. Every report exports to PDF and CSV. Agency plans add white-label PDFs with your own watermark, agency name and author details, plus single-page audits for client landing pages.
Lighthouse focuses on one page's performance and a subset of accessibility. Site Audit Score includes PageSpeed Insights results, then adds what Lighthouse doesn't cover: indexability conflicts, canonical and hreflang validation, schema validation, broken links, sitemap architecture, security headers, content E-E-A-T signals and AI crawler access — across multiple pages.
Yes. Audits only need a public URL — no code access, DNS verification or tracking script. Agencies often run a report before a pitch call to show a prospect exactly what to fix.
Yes. The REST API starts a 17-module audit with one request and returns scores, every issue with its fix, and AI crawler status as JSON. AI agents like Claude Code, Cursor and Codex can run the same audits through our MCP server. It's included with Agency+, costs 2 credits per page, and every API audit is also saved to your dashboard. See the SEO audit API page for the reference.
Paid plans include monthly credits that reset each billing cycle. Adding a website costs 2 credits, scanning a new page costs 2 credits, a full 18-module single-page audit costs 5, and re-checking a single module after you fix something costs just 0.5 credits per page.
