Editorial Policy
SitemapChecker.tools publishes technical SEO guidance alongside reproducible sitemap diagnostics. Our goal is to explain observable technical conditions accurately, cite the evidence behind important claims, and state clearly where only a search engine can provide the final answer.
We prefer primary documentation and reproducible HTTP or XML behavior, distinguish requirements from recommendations, and avoid promises about indexing or ranking outcomes that a third-party tool cannot verify.
Source hierarchy and evidence
For technical SEO claims we prefer primary sources: official search-engine documentation, the Sitemap protocol, HTTP/XML standards, and reproducible public responses. Secondary sources provide context but do not override current primary documentation.
How tool diagnostics are tested
SitemapChecker.tools reports observable behavior from its own requests, including sitemap discovery, XML parsing, HTTP status, redirects, robots directives, and declared canonical signals. Tests are bounded for reliability and abuse prevention.
Fact-checking and wording
We distinguish protocol requirements from recommendations and search-engine signals from guarantees. A canonical conflict is a signal to investigate, not proof of a particular indexing outcome.
Updates and verification
Publication, modification, and last-verified dates should change only after real editorial or verification work. We review material when official documentation or tool behavior changes.
Corrections
Technical errors, outdated instructions, broken sources, or misleading diagnostics should be corrected and the relevant verification metadata updated.
AI and automation
AI or automation may assist drafting, code generation, research organization, and testing, but published technical claims are expected to be checked against primary documentation or reproducible behavior.
Commercial independence
Future advertising or monetization should not determine a tool result, technical conclusion, or independent editorial recommendation.
Scope and limitations
SitemapChecker.tools is independent from search engines. It reports reproducible technical conditions and clearly separates them from internal search-engine decisions that a public HTTP request cannot observe.
