What problem does it solve? Website owners and SEO practitioners struggle to verify that their XML sitemaps follow protocol rules, contain only valid indexable URLs, and scale correctly, or they need to generate a well-structured sitemap from scratch without creating thin programmatic pages that risk search penalties. ## Core Features & Use Cases - Sitemap Validation: Checks XML format, the 50,000 URL per-file limit, HTTP 200 status of listed URLs, accurate lastmod dates, robots.txt references, and flags non-canonical, noindexed, or redirected URLs. - Sitemap Generation: Builds new sitemaps from industry templates with interactive structure planning, quality gates on programmatic location pages, and automatic splitting with a sitemap index at scale. - Issue Reporting: Produces a VALIDATION-REPORT.md with severity-ranked issues and fixes, plus STRUCTURE.md documentation for generated sites. - Use Case: An SEO specialist auditing a client's site can validate the existing sitemap, find broken or noindexed URLs included by mistake, and receive a prioritized fix list. ## Quick Start Analyze the sitemap at https://example.com/sitemap.xml and report any validation issues with recommended fixes.
