If you're looking for a free way to check your website's health, you've probably seen both AuditCrow and SEOptimer in search results. Both offer free audits. Here's how they differ so you can pick the right tool - and why AuditCrow's plain-language report is a strong fit if you don't want to wade through jargon.
First, the honest version
SEOptimer has been around longer and does things AuditCrow's free scan does not: multi-page crawls, backlink data, white-label reports, and ongoing monitoring on its paid plans. The free scan audits one page at a time - it is the taster for the full AuditCrow platform, which audits sites as a whole with ongoing monitoring and is in beta with no paid plans published yet. If you need to crawl a whole site or produce white-labelled client reports today, SEOptimer's paid tiers do that now and we don't.
What AuditCrow offers instead is a genuinely plain-English, prioritised single-page report - including AI-readiness checks SEOptimer doesn't run - and you can read a real, unedited example before you type a URL anywhere.
What Both Tools Do
Each tool scans a URL you provide (and in SEOptimer's case, can crawl multiple pages - meaning it visits many pages in one run). You get a report covering SEO, performance, and often accessibility: a list of issues with explanations and sometimes a score. No signup is required for the basic audit on either platform - you enter a URL and get results.
What is SEOptimer?
SEOptimer is a website audit tool that can check many pages at once (within limits that depend on your plan). It offers a dashboard - a single screen with scores, charts, and recommendations. The free tier gives you a solid snapshot; paid plans (its freemium model: free basics, pay for more) unlock more pages, backlink data (who links to your site), white-label reports, and ongoing monitoring.
AuditCrow: Plain Language, No Signup, Prioritised Fixes
AuditCrow is built for business owners and marketers who don't want to wade through technical jargon. We scan the single page you provide and return a prioritised report: critical issues first, then warnings, then notices. Every finding is explained in plain English with a difficulty rating so you know how hard it is to fix.
- No account required - run a scan and get your report immediately.
- Prioritised by impact and effort - your top fixes in order, not an undifferentiated list.
- A ready-to-send developer note on every fix, so you can act without translating anything.
- Eight categories - structure, SEO, speed, content, trust, accessibility, AI readiness, and enquiry & conversion.

SEOptimer: Deeper Crawls, More Data, Freemium Model
SEOptimer offers a free audit that can crawl multiple pages (limits depend on the plan). Reports include SEO analysis, backlink data (on paid plans - i.e. which sites link to you), and recommendations. The interface is more dashboard-style, with scores and charts. Free users get a solid snapshot; paid plans unlock more pages, white-label reports, and ongoing monitoring.
If you need to audit an entire site (dozens or hundreds of pages) and want ongoing tracking, SEOptimer's paid tiers are worth considering. For a single-page health check with zero friction and a plain-language report you can read and act on, AuditCrow is the better fit.
And the full platform? Against SEOptimer's paid tiers, the AuditCrow platform (in beta) is the closer comparison: site-wide audits on a completable 0 to 1000 Foundations Index, connected Search Console and Analytics data, weekly monitoring, and a goal-steered plain-English action plan from six specialist AI analysts. SEOptimer still wins today on white-label PDF reports and its embeddable audit widget. No AuditCrow paid plans are published yet - the waitlist gets first access.
When to Choose AuditCrow
- You want a quick, single-page audit with no signup.
- You care about plain-language explanations and prioritised action items - no technical jargon.
- You want to know how AI-ready your page is alongside the classic checks.
- You want to see the output first - read the sample report with no commitment.
When to Choose SEOptimer
- You need to crawl many pages in one go (one run that visits lots of URLs).
- You want ongoing monitoring and historical tracking (paid).
- You're comfortable with a more technical dashboard and want backlink data (paid).
Bottom Line
Both tools are legitimate free options. AuditCrow is best for a fast, no-signup, single-page audit with a clear, readable report in plain English. SEOptimer suits users who need multi-page crawls or paid features like monitoring and backlinks. Run a free scan with AuditCrow and try SEOptimer's free audit - then decide which workflow you prefer.
