XML Sitemap Validator & Coverage Checker
Validate an XML sitemap or sitemap index, review listed URL status, redirects, and canonical alignment, and compare sampled crawl discovery with sitemap coverage. Sitemap inclusion supports discovery but does not guarantee crawling or indexing.
2 Input Modes
Sitemap URL or site auto-detect
XML + Sitemap Index
Supports .xml and .xml.gz files
URL Health + Coverage
Status, redirects, canonicals, and sampled gaps
Run an XML Sitemap Check
Validate Your XML Sitemap for Technical SEO Issues
Wranker’s XML sitemap validator separates file rules, sitemap-index health, listed-URL checks, and sampled coverage. This sitemap validator tool helps you validate sitemap XML before deeper crawl or indexing review.
Validate XML Sitemap Structure
Check well-formed XML, the sitemap namespace, required <loc> values, absolute URLs, duplicate entries, date formats, and protocol limits.
Review Index & Child Sitemap Files
Check whether child sitemap files are reachable, parseable, and within supported file and entry limits.
Check Status, Redirects & Canonicals
Review checked entries for non-200 responses, redirects, and declared canonical targets that differ from the listed URL.
Compare Discovered & Sitemap URLs
Use a limited spot crawl to find sampled internal URLs missing from the sitemap and review the resulting coverage indicators.
Keep Your XML Sitemap Clean for Better URL Discovery
Use Wranker’s sitemap XML checker to validate sitemap XML, confirm the file is readable, and review whether listed URLs match the preferred pages you want discovered. A sitemap validator tool cannot guarantee crawling or indexing, but it can expose conflicting, outdated, or incomplete signals.
Align Preferred URLs
List fully qualified canonical URLs so the sitemap, canonical tags, and internal links support the same preferred page versions.
Keep Listed URLs Reachable
Use the sitemap checker tool to identify unavailable or redirected entries so the file points directly to accessible final destinations.
Keep Sitemap Coverage Current
Use sampled coverage to find important internally linked pages missing from the sitemap as the website changes.
Validate Your Sitemap in Four Simple Steps
Use this sitemap checker tool to validate sitemap XML, choose optional URL and coverage checks, and review the grouped output in one workflow.
Choose the Sitemap Target
Use a known sitemap file or start from the site root when Wranker needs to find a sitemap.
Select Additional Checks
Add listed-URL, redirect, canonical, or sampled coverage checks after the sitemap file has been processed.
Run the Sitemap Check
The XML sitemap checker fetches the target, parses XML or sitemap indexes, and processes supported child and compressed files.
Review Findings and Next Actions
The sitemap validator tool groups file, child-sitemap, listed-URL, fetch-log, and sampled coverage findings for focused follow-up.
Use a Sitemap Checker for Audits Migrations, and Launches
Use this sitemap validator tool to validate sitemap XML before Search Console submission, after migrations or major URL changes, and during routine large-site technical QA.
Establish a Sitemap QA Baseline
Use the XML sitemap checker when an audit needs one focused view of sitemap file quality, listed-URL behaviour, and sampled coverage.
Validate Before Sitemap Submission
Validate XML sitemap files before submitting or resubmitting them, then use Search Console to review access and processing feedback.
Recheck After URL Changes
After a migration, confirm that new sitemap files list the intended final URLs and no longer depend on outdated paths or unnecessary redirect chains.
Maintain Sitemap Indexes at Scale
Use the sitemap XML validator to review sitemap indexes and child files when content types, locales, or large URL inventories are split across multiple sitemaps.
Continue the XML Sitemap Validator Workflow
Use a focused Wranker tool to investigate crawl rules, canonical targets, redirect paths, or directional index signals after the sitemap checker tool flags a related issue.
CRAWL ACCESS
Robots.txt Tester
Review published Allow and Disallow rules, user-agent access, blocked resources, and Sitemap directives that may affect discovery.
OpenCANONICAL TARGETS
Canonical Tag Checker
Inspect a flagged page’s declared canonical, resolved final URL, self-reference, cross-domain target, and canonical destination response.
OpenREDIRECT PATHS
URL Redirect Path Checker
Trace each redirect hop, final URL, status code, and canonical context for sitemap entries that do not resolve directly.
OpenINDEX SIGNALS
Google Index Checker
Review directional public index signals for priority URLs after sitemap issues are addressed, then verify owned pages in Search Console.
XML Sitemap Validaton FAQs
Get clear answers about how to validate sitemap XML, use the sitemap checker tool, review supported files and limits, interpret lastmod, redirects, canonical URLs, sampled coverage, Search Console, and indexing.
An XML sitemap validator checks whether a sitemap is reachable and parseable and can review protocol rules such as the root element, namespace, required <loc> entries, URL format and sitemap limits. Wranker can also check listed-URL health, canonical targets and sampled coverage.
Enter a public sitemap URL or start from the website root, select any additional URL or coverage checks, and run the analysis. Review file, child-sitemap, listed-URL and sampled-coverage findings separately before fixing confirmed issues.
The names are often used for the same type of tool, but the scope can differ. A basic checker may only fetch and parse XML, while a broader sitemap validator tool may also review protocol rules, child files, listed-page responses, redirects, canonical targets and coverage.
Wranker’s current interface supports standard .xml sitemap files, gzip-compressed .xml.gz files and sitemap index files. You can enter a known sitemap URL or begin with a website URL and use sitemap discovery.
A single sitemap can contain up to 50,000 URLs and must not exceed 50 MB uncompressed. Larger websites should split URLs across multiple sitemap files and organise them through sitemap index files.
A sitemap index groups multiple child sitemap files. It uses a <sitemapindex> root with <sitemap> entries containing a <loc> for each child file. An index can list up to 50,000 sitemaps and must remain within the 50 MB uncompressed limit.
Google may use <lastmod> when it is consistently accurate and reflects the page’s last significant update. Google ignores <changefreq> and <priority>. Avoid changing <lastmod> for minor updates or simply when regenerating the sitemap.
Usually, list the final, fully qualified canonical URLs you want represented in search results. Avoid redirecting or duplicate alternatives where possible. Redirects or canonical differences should be reviewed to confirm that the sitemap reflects the intended preferred URL.
Wranker’s Spot Crawl compares a limited sample of internally discovered pages with sitemap entries. It can identify sampled pages that appear to be missing from the sitemap, but it is not a complete site crawl or exhaustive inventory of every website URL.
No. A sitemap is a discovery hint and does not guarantee that Google will download the file, crawl every listed URL or index each page. Submit the sitemap in Search Console to review access and processing errors, and use page-indexing reports for indexing issues.
Validate Your XML Sitemap Before Submission
Use Wranker’s sitemap validator tool to check a known file or find one from the site root, then review file access, URL health, and sampled coverage.
Resolve confirmed issues before submission, resubmission, or migration sign-off.
