What problem does it solve?

It helps you fix sitemap errors and create valid XML sitemaps that search engines can crawl reliably, reducing indexing problems and wasted crawl budget.

Core Features & Use Cases

Sitemap validation & issue detection: Checks XML validity, URL HTTP status, lastmod accuracy, robots.txt references, canonical/noindex/redirect rules, and sitemap vs crawled-page mismatches.
Sitemap generation with quality gates: Generates new sitemaps from industry templates, produces STRUCTURE.md documentation, and splits large outputs safely with a sitemap index.
Two clear workflows: Use Mode 1 to analyze an existing sitemap or Mode 2 to generate one when building SEO for a SaaS, blog, or multi-page site.

FAQPage Schema

How do I validate an XML sitemap and fix indexing errors?▼

To validate an XML sitemap, you need to check XML structure, URL HTTP status, lastmod accuracy, and robots.txt references. This process identifies canonical, noindex, and redirect rule mismatches to resolve crawl and index troubleshooting issues.

How do I generate a new XML sitemap for a multi-page website?▼

Generate a new XML sitemap by applying industry templates to build standards-compliant output for pages, posts, images, and videos. This produces a sitemap index with safe splitting and STRUCTURE.md documentation for your site.

What is sitemap vs crawled-page mismatch and how do I check it?▼

Sitemap vs crawled-page mismatch occurs when URLs listed in your XML sitemap do not align with actual crawled pages. You check this by auditing sitemap references against robots.txt rules, canonical tags, and live URL HTTP status.

Can I use a sitemap index to split large XML sitemaps safely?▼

Yes, you can use a sitemap index to split large XML sitemaps safely. Generating output with a sitemap index structures multiple standards-compliant sitemap files, ensuring search engines can crawl large sites without wasting crawl budget.

Why does my lastmod date in the XML sitemap need to be accurate?▼

The lastmod date in your XML sitemap needs to be accurate because search engines use it to determine crawl frequency and prioritize updated content. Validating lastmod accuracy during an SEO audit prevents indexing problems and wasted crawl budget.

Does my robots.txt file need to reference my XML sitemap?▼

Yes, your robots.txt file should reference your XML sitemap to help search engines discover it. During a sitemap audit, checking robots.txt compatibility ensures your canonical, noindex, and redirect rules align with your site indexing strategy.
