Sitemap Health Checker

Validate XML sitemap access, structure, child sitemaps, URL quality, lastmod values, duplicates, and an indexability sample.

Public URLs are fetched securely with strict crawl and rate limits. Reports are not saved to your WordPress database.
Audit up to 2,000 sitemap URLs and optionally test a 10- or 25-URL sample for HTTP and indexability clues.

FREE SITEMAP HEALTH CHECKER

Find XML Sitemap Problems Before They Spread

WebTrendSEO’s Sitemap Health Checker accepts a website or direct sitemap URL and reviews the XML files it discovers.

Choose a maximum of 500, 1,000, or 2,000 sitemap URLs. You can also sample 10 or 25 submitted URLs for HTTP and indexability signals, or skip sampling for a structure-only review.

The report checks sitemap indexes and URL sets, child sitemap access, duplicate or invalid URLs, hostname consistency, lastmod problems, and sampled page signals. It does not submit your sitemap to search engines or guarantee crawling or indexing.

WHY USE OUR SITEMAP HEALTH CHECKER?

Turn Sitemap Files Into a Practical Quality Review

Large sitemap indexes can hide inaccessible child files, mixed hostnames, duplicates, malformed URLs, and unreliable lastmod values. These issues make sitemap maintenance harder and can reduce the usefulness of the signals you provide to crawlers. This checker combines structural validation with an optional, limited page sample. Use the report to confirm patterns and prioritize corrections without treating a sitemap as proof that every URL will be crawled or indexed.

A Limited Review of Public Sitemap Data

FAQS

Sitemap Health Checker FAQs

Learn what the checker validates, how sampling works, and why a valid sitemap does not guarantee indexing.
It reviews a public XML sitemap or sitemap index for access, structure, child files, submitted URL quality, hostname consistency, lastmod values, duplicates, and optional sampled page signals.

Enter a website or sitemap URL, choose a 500, 1,000, or 2,000 URL limit, and select whether to sample 10 or 25 submitted URLs. The checker fetches accessible XML files and organizes the detected issues.

It can flag inaccessible child sitemps, invalid or duplicate URLs, unexpected hostnames, problematic lastmod values, and XML structure issues. The optional sample can add HTTP and indexability clues for selected submitted pages.

The sample requests a limited number of sitemap URLs and reviews available HTP and page-level indexability signals. It is a sample, not a complete crawl, and should not be treated as proof that all remaining URLs share the same status.

No. A sitemap helps search engines dscover and understand submitted URLs, but crawling and indexing depend on many additional signals. A valid sitemap does not guarantee rankings, traffic, or inclusion in a search index.

No. It does not edit XML, remove URL, update lastmod values, submit files to search engines, or change your site. Fix confirmed issues in your CMS or sitemap generator and use your own search-console workflow.
