FREE XML SITEMAP VALIDATOR

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

Enter a known sitemap URL or start from a website root, then choose listed-URL, canonical, and sampled coverage checks.
Public Sitemap URL
Supports XML sitemap files, gzip-compressed XML, and sitemap index files.
Additional Checks
Listed URL Checks
Check Listed URL Status
Report response classes and fetch failures for the sitemap entries Wranker checks.
Flag Redirected Sitemap Entries
Compare Canonical Targets
Compare each checked URL with its declared rel="canonical" target and flag differences for review.
Sampled Coverage
Run a Spot Crawl
Crawl a limited sample of internal URLs and compare discovered pages with sitemap entries.
Adds sampled coverage KPIs and a “Discovered but not in sitemap” report. This is not a complete site crawl.
Adjust severity for canonical differences and choose how redirect chains are reported.

WHAT THE SITEMAP VALIDATOR CHECKS

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.

Use this sitemap checker tool to review the XML file and selected URLs. Coverage is sampled, and sitemap inclusion does not guarantee crawling or indexing.
FILE VALIDATION

Validate XML Sitemap Structure

Check well-formed XML, the sitemap namespace, required <loc> values, absolute URLs, duplicate entries, date formats, and protocol limits.

SITEMAP INDEX

Review Index & Child Sitemap Files

Check whether child sitemap files are reachable, parseable, and within supported file and entry limits.

LISTED URL HEALTH

Check Status, Redirects & Canonicals

Review checked entries for non-200 responses, redirects, and declared canonical targets that differ from the listed URL.

SAMPLED COVERAGE

Compare Discovered & Sitemap URLs

Use a limited spot crawl to find sampled internal URLs missing from the sitemap and review the resulting coverage indicators.

Why XML Sitemap Validation Matters

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.

How the Sitemap Validator Tool Works

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.

01

Choose the Sitemap Target

Use a known sitemap file or start from the site root when Wranker needs to find a sitemap.

02

Select Additional Checks

Add listed-URL, redirect, canonical, or sampled coverage checks after the sitemap file has been processed.

03

Run the Sitemap Check

The XML sitemap checker fetches the target, parses XML or sitemap indexes, and processes supported child and compressed files.

04

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.

When to Use a Sitemap Validator Tool

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.

TECHNICAL AUDITS

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.

SEARCH CONSOLE

Validate Before Sitemap Submission

Validate XML sitemap files before submitting or resubmitting them, then use Search Console to review access and processing feedback.

MIGRATION QA

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.

LARGE-SITE QA

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.

Frequently asked questions

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.

READY TO VALIDATE YOUR SITEMAP?

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.
