Quick answer: Moz's automated Site Crawl lives inside Moz Pro (from $99/mo, with a trial that converts to a paid plan). If you just need a fast audit of one page — a Moz-style crawl test without the subscription — WebsiteLinter's free Moz alternative checks SEO, site speed, security headers, and accessibility on any public URL in about 30 seconds. No account, no credit card, no site verification.
The two tools answer different questions. Moz Pro is an ongoing SEO campaign platform. WebsiteLinter is an instant first-pass health check you can run on your own site, a client's site, or a competitor's — right now.

What Moz Site Audit (Site Crawl) Actually Does
Moz Pro's Site Crawl is a recurring, multi-page crawler for verified sites. Once you set up a campaign, it crawls on a schedule and flags technical SEO issues: redirect chains, missing titles, duplicate content, broken links, and crawl errors.
That workflow is genuinely useful when you manage SEO over months. The friction shows up when you don't:
- It requires a Moz Pro campaign. The automated crawl is not one of Moz's free tools — the free trial is the advertised on-ramp, and it converts to a paid plan.
- It is SEO-only. Site Crawl does not measure page speed (Core Web Vitals), browser security headers, or WCAG accessibility.
- It is slow to first answer. Campaign setup plus a scheduled crawl means hours or days before your first report — not 30 seconds.
Moz Crawl Test vs. a Free WebsiteLinter Audit
When people search for a "Moz crawl test," they usually want one thing: tell me what's broken on this page. Here is how the two paths compare:
| WebsiteLinter (free) | Moz Pro Site Crawl | |
|---|---|---|
| Price | Free — 3 audits/day | From $99/mo |
| Signup required | No | Yes |
| Works on any public URL | Yes — no verification | Campaign setup required |
| Scope | One URL, four pillars | Whole site, SEO only |
| Site speed (Core Web Vitals) | Yes | No |
| Security headers | Yes | No |
| Accessibility (WCAG 2.1) | Yes | No |
| Time to first report | ~30 seconds | Hours–days |
Moz Site Speed? Moz Doesn't Measure It
A common surprise: Moz's Site Crawl does not test site speed. Page experience — Lighthouse performance, Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift — is a confirmed Google ranking signal that Moz leaves to other tools.
Every free WebsiteLinter audit includes a full speed pass: Lighthouse score, Core Web Vitals lab metrics, time to first byte, render-blocking resources, and image weight. If you were looking for a "Moz site speed" test, the free website speed test is the direct equivalent — and it runs alongside the SEO findings in the same report.
Moz Content Audit: What a Page-Level Check Covers
Moz approaches content through keyword research and on-page optimization scores inside campaigns. WebsiteLinter flags the page-level content signals that decide whether a single URL can rank:
- Title tag and meta description quality (length, duplication, click-through potential)
- Heading hierarchy (H1–H3 structure and keyword usage)
- Image alt text coverage
- Internal link integrity and thin-content clues
For a money page or a new landing page, that is usually the entire content audit you need. A full site-wide editorial inventory is a separate, larger job.
The Moz Website Grader Question
Moz does not offer a single overall "website grader" score — its free tools grade individual signals (Domain Authority, link metrics, local presence) one at a time. WebsiteLinter rolls everything into one composite 0–100 health score across SEO, performance, security, and accessibility, with every failing check ranked Critical, Important, or Passed.
If you want the broadest version of that grade, the website health checker runs the same four-pillar audit with the same no-signup workflow.
When Moz Pro Is Still the Right Choice
Be honest about scope. Choose Moz Pro when you need:
- Keyword research and SERP analysis at scale
- Rank tracking over time
- Backlink index and link intersect research
- Scheduled, multi-page crawls of a verified site
Choose WebsiteLinter when you need an instant audit of any public URL — especially for prospect checks, client triage, pre-launch reviews, and competitor spot checks. Many teams run both: WebsiteLinter for the first pass, Moz for the ongoing campaign.
Frequently Asked Questions
Is there a free Moz SEO audit?
Moz publishes free individual tools and an SEO audit checklist, but its automated Site Crawl requires a Moz Pro campaign. WebsiteLinter's free audit needs nothing: paste a URL, get results in about 30 seconds.
Can I run a Moz crawl test on a competitor's site?
Moz Site Crawl requires campaign setup tied to a site you manage. WebsiteLinter audits any publicly accessible URL — competitors, prospects, clients — because it reads the same public page data a browser does.
Does the free audit replace Moz Pro?
No. It replaces the first step: finding out what's wrong right now. If the findings show you need keyword research, rank tracking, or backlink analysis, add Moz Pro (or another suite) after the audit proves the need.
How does WebsiteLinter compare to other Moz alternatives?
We've published head-to-head breakdowns for the most-searched suites: Moz Pro alternative, WooRank alternative, free Screaming Frog alternatives, and Semrush Site Audit alternatives.
