Sitemap Analyzer

What it does

Goes through the XML sitemap you paste and assesses it against established practice. Flags structure, lastmod usage, prioritization and URLs that probably should not be included.

Your XML sitemap gives Google wrong instructions about which pages are important

The XML sitemap is your site's official communication channel to Google — it tells the search engine which pages exist, when they were last updated, and how important they are. But most sitemaps are full of errors: they include pages that shouldn't be indexed (noindex pages, redirects, 404s), miss important pages that should be there, have lastmod dates that make Google ignore updates, and contain thousands of low-priority pages that dilute signals. The result is that Google uses crawl budget inefficiently and important pages are indexed slower than necessary.

• Sitemap includes pages with noindex, redirects and 404 errors confusing Google
• Important pages missing from sitemap and discovered late or never by Google
• Wrong lastmod dates making Google ignore actual content updates
• Thousands of low-priority pages in sitemap diluting signals for important pages

A cleaner sitemap that points Google to your most important pages

Sitemap Analyzer goes through the sitemap content you paste and holds it up against Google's guidelines and established practice. The tool looks at how the file is structured, whether lastmod and priority are used sensibly, and which URL patterns suggest pages you probably don't want indexed. You get a review with findings, reasoning and a proposal for how the sitemap should be set up.

• Structure review: assesses the sitemap against Google's guidelines and established practice
• Coverage gaps: describe the page types your site has, and what appears to be missing is flagged
• URL patterns: flags URLs that look like pagination, filters, tags, search results and other pages that rarely belong in a sitemap
• Structure proposal: a recommended layout with sensible use of lastmod and priority, ready to build into your sitemap generation

Features

• URL pattern review: flags URLs in the sitemap that show signs of pagination, filtering, tags or other low-value pages
• Lastmod assessment: looks at the date pattern in the file — identical lastmod across all URLs is a typical sign of a misconfiguration
• Sitemap index assessment: evaluates the split for large sites with multiple sitemap files
• Structure proposal: a concrete proposal for how the sitemap should be built, ready to implement in your CMS or build process

How it works

1. Paste the contents of the XML sitemap — the whole file or a representative excerpt
2. The tool reviews structure, URL patterns and lastmod usage against Google's guidelines and established practice
3. Get a review with findings and a proposal for a cleaner sitemap structure

Use cases

• Large websites with 10,000+ pages where sitemap quality directly affects crawl efficiency
• E-commerce websites with dynamic product pages constantly being added and removed
• Multilingual websites needing separate sitemaps for each language with correct hreflang references

Why use Sitemap Analyzer?

The XML sitemap is the most direct communication channel between your website and Google. A well-configured sitemap tells Google which pages are important, when they were last updated, and how they relate to each other. But most sitemaps are full of errors that actively harm indexing — URLs that shouldn't be there, lastmod dates that mean nothing, and thousands of low-priority pages diluting signals.

Sitemap Analyzer gives you a grip on that channel. Paste the file and you get a review of what looks wrong, why it's a problem, and a structure proposal you can build into your sitemap generation. The tool runs when you start it — it's a review you do when needed, for instance after a migration or when indexing behaves unexpectedly.

For Nordic websites with content in several languages, the sitemap setup is especially fragile. Multilingual sitemaps with hreflang attributes are complex and error-prone — a single mistake can cause the wrong language version to appear in search results for an entire market. Reviewing the hreflang references in your sitemap at regular intervals catches that kind of error before it costs anything.

FAQ

How important is the XML sitemap really for SEO?

For small websites (under 500 pages) with good internal link structure, the sitemap is less critical — Google finds most pages through links. But for large websites (1000+ pages), new websites, or websites with poor internal linking, the sitemap is essential. It's the fastest way to tell Google about new pages and updates, and it can shorten the time before new content gets indexed.

Should I include all pages in the sitemap?

No — the sitemap should only contain pages you want Google to index. Exclude noindex pages, redirect pages, 404 pages, paginated pages (page 2, 3, etc.), filter URLs, and other low-value pages. A tight sitemap with only important pages sends clearer signals than a sitemap with thousands of irrelevant URLs.

How often should the sitemap be updated?

The sitemap should update automatically when content changes. Most CMSs (WordPress, Shopify and similar) handle this themselves, but many get it wrong — they stamp a new lastmod date on every page when a single page changes, and then lastmod loses its value to Google. Sitemap Analyzer looks for exactly that pattern in the file you paste.

What's the difference between sitemap and sitemap index?

A single sitemap can contain max 50,000 URLs or be max 50 MB. For larger websites you use a sitemap index that points to multiple individual sitemap files. If you paste the index file, the split is assessed — and you get a proposal for how the files should be divided given your site structure.

Does the tool support multilingual sitemaps?

Yes. If you paste a sitemap with hreflang attributes, the references in the material are reviewed: whether the language versions point back at each other, and whether the language codes are valid. For Nordic websites with nb, sv, da, fi and en versions this is worth checking, because hreflang errors in sitemaps are a common reason the wrong language version shows up in search results.
