XML Sitemap Checker
Make sure crawlers can find your URL inventory.
What it calculates
Sitemap discovery via robots.txt Sitemap directive and conventional /sitemap.xml paths.
Why it matters
Without a discoverable sitemap, large sites depend on crawl alone — new URLs index slower.

Apex domain only — no paths, IPs, or ports.
What this checker verifies
Whether a sitemap URL is declared in robots.txt or responds at common locations on the apex host.
Scans run from Learn Domains infrastructure against the apex domain you submit. We do not crawl arbitrary URLs, probe ports, or run penetration tests. Results describe observed configuration at scan time.
Treat output as operator signal — not a security certification, ranking guarantee, or legal attestation.
How to interpret the result
Missing sitemap slows discovery — especially for deep URLs. Validate sitemap XML separately in Search Console.
Severity labels rank urgency: critical issues often block traffic or trust; high issues degrade deliverability or crawl efficiency; medium and low items are worth scheduling before they compound.
When a finding is marked inference or needs human review, confirm in your DNS host, CDN, or registrar before shipping a production change.
Common causes of this issue
Sitemap only on www, wrong path after CMS change, or robots.txt missing Sitemap directive.
Misconfigured migrations, partial CDN setups, and copied DNS templates are the usual culprits. Compare www and apex behavior when redirects look inconsistent.
If you recently changed hosts, allow TTL propagation before re-checking — a stale cache can look like a failure for up to 48 hours.
How to fix it
Publish sitemap.xml (or index), reference it in robots.txt, and submit in Google Search Console.
Document what you changed and when. Technical change detection inside Learn Domains compares future scans to this baseline so regressions surface in the Operator.
For email posture issues, coordinate with whoever owns your ESP (Google Workspace, SendGrid, etc.) so SPF and DMARC align with live senders.
When to re-check
After large content releases or URL structure changes.
Re-run after DNS TTL windows, certificate renewals, or deploys that touch edge configuration. Weekly monitoring catches drift before launch deadlines.
Connected workspaces in Learn Domains store scan history — public checks are ephemeral snapshots for visitors.

FAQ
- Is the XML Sitemap Checker free?
- Yes. Anonymous visitors can run a limited number of checks per day. Results are cached briefly to keep scans fast. Full history, change detection, and Growth Orders require a Learn Domains workspace.
- Does this scan my entire site?
- No. Public tools inspect DNS, HTTPS entry points, robots.txt, sitemap discovery, mail records, and response headers for the apex domain. They do not brute-force paths or audit every URL.
- Can I scan any domain?
- You can check publicly registered domains you have permission to evaluate. We block internal networks, localhost, and platform abuse targets. Rate limits apply per visitor and per domain.
- How is this different from Learn Domains in the app?
- The app runs the same Technical Intelligence engine with saved history, workspace context, AI Operator interpretation, and one-click Growth Orders. Public tools deliver a snapshot; the product runs the operating loop.
