Each one's way of doing it, and the point where it stops.
Website Audit crawls the whole site on a weekly or monthly schedule and reports security, speed, status codes, redirects, indexation, meta tags and links with a fix for each; a standalone audit checks any site without a project. Where it stops: No free plan; the trial audit stops at 10,000 pages, the default is 1,000 pages per audit, and region blocks or Cloudflare bot rules can stop its German-based crawler until whitelisted.
Site Audit runs 140+ checks once, weekly or daily, scores Site Health from 0 to 100 and gives each issue a How to fix note; eight thematic reports split the work, and every plan checks access for eight AI crawlers. Where it stops: The Free plan audits 100 pages; JavaScript rendering only on Pro+ and Advanced; unused monthly pages don't roll over; the trial blocks exports.
Site Audit crawls your verified site for 170+ technical and on-page issues on a daily, weekly or monthly schedule, with broken internal links and orphan pages checked in every crawl and issues exported with fixing instructions. Where it stops: Free only for sites you verify; sites over 5,000 pages need Starter or higher, sites you don't own need a paid plan, and password-protected staging sites need Advanced.
Site Audit crawls weekly, scores SEO health and ranks issues by priority; the WordPress plugin runs the audit inside wp-admin and applies AI one-click fixes to titles and meta descriptions. Where it stops: Weekly crawls only; the free account covers 150 pages per project, and the large page figure on the home page is spread across 15 projects, not one site.
The Page indexing report lists every URL Google left out with the reason, plus 404s found in the past month; URL Inspection tests the live page with rendered HTML, and Core Web Vitals come from real-user field data. Where it stops: Only your verified sites, and only what Google crawled; it is not a crawler. Crawl Stats and the robots.txt report need a domain-level property.
The technical audit runs daily, weekly or on demand and lists issues by priority with an explained fix, including URL-level checks for tracking parameters, double slashes and internal search pages. Where it stops: No dedicated broken-link report in our data; Free audits 10 pages, and Individual audits JavaScript sites without rendering.
