Sitemap Source

Analyze and validate sitemaps instantly

A Sitemap Analyzer helps you inspect what your sitemap actually contains before you submit it, debug it, migrate it, or use it for an SEO audit.

Instead of scanning raw XML by hand, this tool turns sitemap data into a clear, searchable table with useful validation notes.

You can use it to:

  • parse XML sitemaps
  • inspect sitemap index files
  • validate plain text URL lists
  • count total URLs
  • detect invalid or missing URLs
  • find duplicate URLs
  • check priority values
  • review last modified dates
  • sort by URL, update date, or priority
  • filter broken entries only
  • export results as CSV or JSON

Paste a sitemap, upload a .xml or .txt file, and review the structure directly in your browser.


What this sitemap tool does

This tool is designed for practical sitemap inspection and SEO troubleshooting.

It can detect and analyze three common sitemap input types:

  • Standard XML sitemaps using <urlset>
  • Sitemap index files using <sitemapindex>
  • Plain text URL lists with one URL per line

For standard sitemaps, it reads fields such as:

  • <loc>
  • <lastmod>
  • <changefreq>
  • <priority>

For sitemap index files, it reads:

  • child sitemap URL
  • last modified date when available

For plain text lists, it treats each non-empty line as a URL and validates it the same way.

That makes it useful for both technical SEO work and general URL cleanup.


Why sitemap analysis matters

A sitemap is not just a list of pages. It is a discovery and maintenance signal for search engines and other crawlers.

A clean sitemap can help crawlers understand:

  • which URLs you want discovered
  • when content was last updated
  • how large your URL inventory is
  • whether your sitemap is split correctly
  • whether your site exposes duplicate or malformed URLs

A broken or messy sitemap can create avoidable problems.

Common issues include:

  • invalid URLs
  • empty <loc> nodes
  • duplicate page URLs
  • outdated URLs left from old templates
  • missing or incorrect <lastmod> values
  • too many URLs in one sitemap file
  • sitemap indexes that point to stale child sitemaps

This tool gives you a fast way to catch those issues before you rely on the sitemap in production.


XML sitemap support

Standard XML sitemaps use a <urlset> root element.

Each URL entry usually looks something like this:

<url>
  <loc>https://example.com/page/</loc>
  <lastmod>2026-05-21</lastmod>
  <changefreq>weekly</changefreq>
  <priority>0.8</priority>
</url>

This tool parses each <url> entry and displays the values in a readable table.

The most important field is <loc>, because it identifies the actual URL.

Optional fields like <lastmod>, <changefreq>, and <priority> can still be useful during audits, especially when you want to understand update patterns or compare different sitemap generation strategies.


Sitemap index support

Large websites often use a sitemap index instead of putting every URL into one file.

A sitemap index points to multiple child sitemaps, such as:

  • page sitemap
  • post sitemap
  • image sitemap
  • product sitemap
  • category sitemap
  • localized sitemap
  • tool sitemap

This tool detects <sitemapindex> files and lists the sitemap URLs inside them.

That helps you check whether:

  • the index contains sitemap entries
  • child sitemap URLs are valid
  • child sitemap URLs are duplicated
  • last modified values are present
  • the sitemap structure is organized clearly

For large sites, this is one of the fastest ways to understand sitemap coverage at a high level.


Plain text URL list support

Not every URL audit starts with XML.

Sometimes you have a raw list copied from:

  • a crawler export
  • a CMS export
  • a spreadsheet
  • a migration file
  • a Search Console export
  • a routing table
  • a manually collected URL list

If the input does not start with XML, this tool treats it as a plain text list.

Each non-empty line becomes one URL entry.

That makes the tool useful even when you are not working with a formal sitemap file yet.


SEO health and validation checks

The validation panel highlights issues that deserve attention.

Missing URL locations

Every sitemap URL entry should include a usable location.

If an entry is missing <loc>, the tool marks it as a critical issue.

Without a URL location, the entry cannot do anything useful for discovery or auditing.

Invalid URLs

The tool checks whether each URL is valid and starts with http:// or https://.

Malformed or relative URLs are flagged because sitemap URLs should be absolute and crawlable.

Examples of problematic values include:

/about/
www.example.com/page
example.com/page
ftp://example.com/file

Use absolute URLs such as:

https://example.com/about/

Duplicate URLs

Duplicate URLs are flagged as warnings.

A few duplicates may not destroy a sitemap, but they make audits noisier and can reveal problems in routing, localization, pagination, or sitemap generation logic.

Invalid priority values

The <priority> value should be between 0.0 and 1.0.

Values outside that range are flagged as warnings.

This helps catch mistakes such as:

<priority>2</priority>
<priority>high</priority>
<priority>-1</priority>

Empty sitemap files

If a sitemap contains no <url> entries, the tool marks it as a critical issue.

If a sitemap index contains no <sitemap> entries, that is also flagged.

Sitemap size limit warnings

The tool warns when a sitemap or URL list exceeds 50,000 URLs.

Large sites should split sitemap files and use a sitemap index to organize them cleanly.


Sitemap metrics explained

The top dashboard gives you a quick summary of the parsed input.

Format type

The tool identifies whether the input is:

  • Standard Sitemap
  • Sitemap Index
  • Plain Text List

This helps you immediately confirm whether the file was detected correctly.

Total URLs

This shows how many entries were parsed.

For standard sitemaps, it counts <url> entries.

For sitemap indexes, it counts child <sitemap> entries.

For plain text lists, it counts non-empty URL lines.

Average priority

For standard sitemaps that include <priority>, the tool calculates the average valid priority value.

This can help you spot unusual sitemap generation patterns.

For example, if every page has priority 1.0, the field may not be giving any meaningful signal.

Latest modified date

The tool finds the newest valid <lastmod> date across the parsed entries.

This is useful when checking whether a sitemap is being refreshed correctly after publishing or deployment.


Search, sort, and filter sitemap entries

Large sitemaps are difficult to inspect without controls.

The toolbar helps you narrow the data quickly.

You can:

  • filter URLs by path or keyword
  • sort URLs A to Z
  • sort URLs Z to A
  • sort by newest updated date
  • sort by highest priority
  • show only broken or invalid URL entries

This is useful when you want to answer questions like:

  • Are all /tools/ pages included?
  • Are old /blog/ URLs still present?
  • Which pages were updated most recently?
  • Are priority values being assigned correctly?
  • Are there any malformed URLs hiding in the sitemap?

Export sitemap data as CSV or JSON

Sometimes the best next step is to move the sitemap data into another tool.

This Sitemap Analyzer can export parsed results as:

  • CSV for spreadsheets and SEO audits
  • JSON for developer workflows and debugging

CSV export

CSV export is useful when you want to:

  • audit URLs in a spreadsheet
  • compare sitemap files
  • review last modified dates
  • find duplicate patterns
  • share findings with a client or teammate
  • document migration coverage

For standard sitemaps, CSV includes:

  • URL
  • Last Modified
  • Change Freq
  • Priority

For sitemap indexes, CSV includes:

  • Sitemap URL
  • Last Modified

JSON export

JSON export is useful when you want to:

  • inspect parsed fields in detail
  • compare output programmatically
  • save a debugging artifact
  • pass data into another script or workflow

How to use the Sitemap Analyzer

1. Paste sitemap XML or upload a file

Paste raw XML sitemap data into the input area.

You can also upload:

  • .xml
  • .txt

Use .xml for standard sitemaps and sitemap indexes.

Use .txt for plain URL lists.

2. Review parsing errors

If the XML cannot be parsed, the tool shows a parsing error.

This usually means the file contains malformed XML, an incomplete sitemap fragment, or a root element that is not recognized.

The tool expects XML sitemaps to use either:

  • <urlset>
  • <sitemapindex>

3. Check the dashboard

After parsing succeeds, review the summary cards:

  • format type
  • total URLs
  • average priority
  • latest modified date

These numbers give you the first high-level signal about the sitemap.

4. Review SEO health and validation

Look at the validation panel for critical issues and warnings.

Fix critical issues first, especially missing or invalid URLs.

Then review warnings such as duplicates, invalid priority values, and size-limit issues.

5. Search and sort URLs

Use the search field to filter by path, section, keyword, locale, or URL pattern.

Then sort by URL, last modified date, or priority depending on what you are auditing.

6. Use Broken Only when debugging

Enable Broken Only to show entries with missing or invalid URLs.

This is especially helpful when working with large sitemap exports where broken entries are hard to find manually.

7. Export the results

Use CSV for spreadsheet review.

Use JSON for developer-focused debugging or automation.


Common sitemap audit workflows

Check whether a new page type is included

Search for a path segment such as:

/tools/
/blog/
/products/
locations/

This helps confirm whether the sitemap generator is including the right sections.

Find outdated URLs after a migration

Paste the new sitemap and search for old path patterns.

This can reveal leftover routes that should be redirected, removed, or updated.

Review last modified freshness

Sort by newest updated date to see whether recent pages appear with fresh <lastmod> values.

If your sitemap still shows old dates after publishing changes, your sitemap generation or cache layer may need review.

Validate a sitemap index

Paste the sitemap index and confirm that all child sitemap URLs are valid.

This is especially useful for larger sites with many content types or localized page groups.

Clean a raw URL export

Paste a plain text URL list and use the validation checks to find malformed URLs before turning the list into a sitemap.

Prepare data for an SEO report

Export the parsed sitemap as CSV, then review it in a spreadsheet with filters, notes, and status columns.


Understanding sitemap fields

<loc>

The <loc> field is the URL location.

This is the most important field in a sitemap entry.

It should be a full absolute URL using http:// or https://.

<lastmod>

The <lastmod> field tells crawlers when the URL was last modified.

It should represent the actual content update date when possible, not just the time the sitemap file was regenerated.

Accurate last modified dates make sitemap data more useful during audits.

<changefreq>

The <changefreq> field describes how often a page is expected to change.

Common values include:

  • always
  • hourly
  • daily
  • weekly
  • monthly
  • yearly
  • never

Not every crawler relies heavily on this value, but it can still be useful as internal documentation of expected update patterns.

<priority>

The <priority> field is a value from 0.0 to 1.0.

It is meant to express the relative priority of URLs within the same site.

It should not be treated as a magic ranking boost.

The more practical use is to check whether your sitemap generator is assigning values consistently and intentionally.


Common mistakes and how to fix them

Using relative URLs

A sitemap should not contain relative paths such as:

/contact/

Use the full URL instead:

https://example.com/contact/

Leaving old URLs in the sitemap

Old URLs from previous site structures can create noise and confuse audits.

Remove outdated URLs or make sure they are handled correctly with redirects and canonical URLs.

Including duplicate URLs

Duplicate entries usually point to a generation bug.

Check whether pagination, localization, trailing slashes, canonical variants, or query parameters are producing repeated URLs.

Setting every priority to 1.0

If every page has the same maximum priority, the priority field is not adding useful information.

It is often better to use priority intentionally or omit it entirely if it does not serve a clear purpose.

Using invalid priority values

Priority must stay between 0.0 and 1.0.

Values like 2, 100, high, or empty strings should be cleaned up.

Forgetting to split large sitemaps

A single sitemap should not grow endlessly.

For large sites, split URLs into multiple sitemaps and connect them with a sitemap index.

Trusting the sitemap without checking it

Generated sitemaps can break after routing changes, CMS updates, plugin changes, deployment bugs, or caching issues.

A quick inspection can catch problems before crawlers discover them the hard way.


Sitemap analyzer vs sitemap generator

A sitemap generator creates sitemap files.

A sitemap analyzer checks what those files contain.

Sitemap generator

Use a generator when you need to create:

  • XML sitemap files
  • sitemap indexes
  • automated sitemap output
  • sitemap routes in your app or CMS

Sitemap analyzer

Use an analyzer when you need to inspect:

  • whether URLs are valid
  • whether the sitemap is empty
  • whether duplicate URLs exist
  • whether last modified dates look correct
  • whether the sitemap exceeds common limits
  • whether exported URLs match your expectations

Most serious SEO workflows need both.

Generating a sitemap is only half the job. Verifying it is what keeps the sitemap trustworthy.


Practical SEO tips for cleaner sitemaps

Include only canonical URLs

Your sitemap should point to the URLs you actually want indexed.

Avoid filling it with filtered URLs, duplicate parameter URLs, or non-canonical versions unless there is a clear reason.

Keep sitemap sections organized

For larger sites, separate sitemaps by content type.

For example:

  • pages
  • posts
  • products
  • categories
  • tools
  • images
  • localized pages

This makes audits much easier.

Keep lastmod meaningful

Use <lastmod> when you can provide an accurate content update date.

Do not update every URL’s lastmod value on every deploy unless the content truly changed.

Remove broken or redirected URLs

A sitemap should represent clean destination URLs.

If a URL redirects, errors, or no longer exists, it usually should not remain in the sitemap.

Recheck after major changes

Always inspect your sitemap after:

  • CMS migrations
  • route changes
  • slug updates
  • localization changes
  • template refactors
  • deployment pipeline changes
  • sitemap plugin updates

Sitemap bugs are easy to miss visually, but they can affect large parts of a site.


Why this tool is useful

You can open a sitemap in a browser, but raw XML is not a comfortable audit interface.

This tool makes sitemap review faster by giving you:

  • format detection
  • URL count metrics
  • validation warnings
  • duplicate detection
  • priority checks
  • latest modification tracking
  • searchable URL tables
  • broken-entry filtering
  • CSV and JSON export

It is especially useful when you want to quickly answer:

  • Is this sitemap valid enough to use?
  • How many URLs does it contain?
  • Are there malformed entries?
  • Are there duplicate URLs?
  • Does the sitemap index point to valid child sitemaps?
  • Are recent pages represented correctly?
  • Can I export this sitemap for a deeper audit?

That saves time for developers, SEOs, content teams, and site owners.


Privacy-friendly sitemap inspection

This tool works from pasted sitemap data or a local file upload in your browser.

You do not need to create an account, install a crawler, or send your sitemap file through a server just to inspect its structure.

For public sitemaps, that is convenient.

For staging exports, migration files, private URL inventories, and internal audits, local browser-side analysis is especially useful.


Perfect for

  • technical SEOs auditing sitemap files
  • developers debugging sitemap generation
  • site owners checking whether URLs are included
  • content teams reviewing migration exports
  • agencies preparing SEO reports
  • QA testers checking route changes
  • publishers validating large URL inventories
  • ecommerce teams reviewing product sitemap coverage
  • anyone who needs a fast XML sitemap checker or URL list validator

Paste a sitemap, upload an XML file, inspect the URLs, validate common issues, search and sort entries, filter broken URLs, and export the results as CSV or JSON — all directly in your browser.
