Indexability and crawl signals
Noindex directives, canonical tags, robots.txt rules and the XML sitemap, so you can spot pages that search engines may skip or misread.
Free SEO audit tool for technical website checks
Paste a public URL and get a prioritised technical SEO audit: indexability, metadata, headings, canonical tags, hreflang, robots.txt, sitemap and structured data, with a clear fix for every issue.
What the SEO audit checks
A website SEO checker is only useful if you know what it looks at. These are the technical and on-page signals covered by the report.
On-page signals
Title and meta description length, a single clear H1, heading order, image alt text, content depth and the Open Graph and Twitter tags used when a page is shared.
International SEO
Language attribute, hreflang annotations, reciprocal links between language versions and x-default, checked against a limited number of alternates.
Structured data and technical basics
JSON-LD presence and validity, HTTPS and redirects, compression, favicon and a small sample of same-site links to catch broken URLs.
From URL to prioritised report
The audit is built for a quick technical health check, not a week-long crawl.
Enter a public URL
No account is needed. The page and a few supporting public files such as robots.txt and the sitemap are fetched with ordinary requests.
Read findings by priority
Each finding has a severity and a confidence level, an explanation of why it matters and concrete remediation steps you can hand to a developer.
Fix, then scan again
Re-scan after your changes to confirm the issue is gone, and export the report as printable HTML, JSON or CSV to share with your team.
Who uses it
One report, readable by people who do not live in search consoles.
Site owners and marketers
Get a plain-language view of what is holding back a page before you brief a developer or an agency.
Developers
Verify metadata, canonical and hreflang changes after a release without writing a custom script.
Agencies and consultants
Use a shareable report as the starting point of a client conversation. See the agency page for what is available.
What this audit is, and what it is not
RedSentinel reports what it observes on the submitted page. It does not invent benchmarks or ranking data.
Single-page technical analysis
The submitted URL plus a limited set of public supporting resources are analysed in one pass.
Available todaySite-wide crawl
The audit is not a crawler. It does not map every page of a site or follow internal links across the whole domain.
Not availableRankings, traffic and keyword data
No positions, search volume, backlinks or traffic figures are reported. Use Search Console for real search performance.
Not availableRendering and Core Web Vitals
Scripts are never executed, so client-side rendered content and performance metrics are outside the report.

SEO audit questions
Is the SEO audit really free?
Yes. The public scanner can be used without an account. Fair-use rate limits apply so that the service stays available to everyone.
Do I need to sign up to check my website for SEO issues?
No. Enter the URL of a public page and the report is generated straight away. An account is only needed for saved sites and scheduled re-scans.
Does it crawl my entire website?
No. It analyses the page you submit and a few public files such as robots.txt and the sitemap. For a full-site crawl you need a dedicated crawler.
How is this different from Google Search Console?
Search Console shows how Google actually sees and ranks your site. RedSentinel checks the technical configuration of a page on demand. The two complement each other.
Can I keep a copy of the report?
Yes. A report can be exported as printable HTML, JSON or CSV, and shared through a link you can revoke.
