How to Compare Sitemap URLs Online for Free
Quick Answer: Use the Word Spinner Sitemap URLs Comparison Tool to compare two XML sitemaps side by side for free. It shows you which URLs were added, removed, or unchanged between any two sitemaps, supports sitemap index recursion up to 3 levels, and lets you export results as CSV or PDF. No sign-up needed.
What Is a Sitemap URLs Comparison Tool?
A sitemap URLs comparison tool lets you take two XML sitemap files and see exactly what changed between them. Instead of manually scanning hundreds or thousands of URLs, the tool fetches both sitemaps, compares every entry, and groups results into three categories: Added, Removed, and Unchanged.
This matters because sitemaps change constantly. You add new pages, remove old ones, or update priority flags. A comparison tool tells you in seconds what a manual audit would take hours to uncover.
For SEO professionals and site owners managing sites with hundreds of pages, this is the difference between catching a crawl issue and missing it for weeks.
The Word Spinner version is free, runs entirely in your browser, and never sends your sitemap data to any server. Your URLs stay private.

Why Compare Sitemap URLs?
Sitemap files are your direct line to Google. They tell search engines which pages exist on your site, how often they change, and which ones matter most. When your sitemap changes and you don't notice, you can end up telling Google to crawl pages that no longer exist or leaving new pages out of the index entirely.
Three scenarios where sitemap comparison saves you:
Site migrations and redesigns. Moving from staging to production? A sitemap comparison confirms every migrated URL matches what you expect. Missing pages show up as Removed. New pages show up as Added.
One export and your migration log is done.
Content launches and pruning. When you publish 50 new guides or remove an outdated section, the sitemap changes. A quick diff confirms Google will discover exactly the right set of new pages and stop being told about retired ones.
Team audits and client handoffs. Need to show a client what changed on their site this quarter? Export the PDF report. It includes both sitemap URLs, the comparison date, a summary of counts, and the full URL list with status labels. Clean, professional, and instant.
How to Use the Word Spinner Sitemap URLs Comparison Tool
The tool works in four steps. You don't need to sign up, install anything, or share your email.
Step 1: Open the Tool
Go to the Sitemap URLs Comparison Tool on tools.word-spinner.com. The interface shows two input fields side by side, one for each sitemap you want to compare.
Compare Your Sitemaps FreeStep 2: Enter Your Sitemap URLs
You have two options. Enter the full URL to an XML sitemap file for example, https://yoursite.com/sitemap.xml or enter just a domain name like yoursite.com. If you enter a domain, the tool automatically checks the site robots.txt for a Sitemap directive and locates the file for you.
This robots.txt auto-discovery is unique to Word Spinner. Most comparison tools require you to know and type the exact sitemap path. Word Spinner finds it for you.
Enter your first sitemap in the left field and the second sitemap in the right field. Click the Compare button.
Step 3: Review the Categorized Results
The tool fetches both sitemaps and displays the results in three tabs:
- Added URLs that exist in the second sitemap but not in the first. These are your new pages.
- Removed URLs that existed in the first sitemap but are gone from the second.
- Unchanged URLs present in both sitemaps.
Each tab shows the full URL list with a live search bar so you can filter results instantly. The summary bar at the top shows the count for each category.
Step 4: Export or Copy the Results
Once you have your comparison, you have three options:
- Copy to Clipboard Copies all categorized URLs for pasting into a spreadsheet or document.
- Export CSV Downloads a CSV file with all URLs and their status column (Added, Removed, Unchanged).
- Export PDF Downloads a formatted PDF report with both sitemap URLs, the comparison date, a summary of counts, and the full categorized list.

Real-World Use Cases
Staging vs production verification. You maintain a staging version of your site with content changes queued up. Before pushing live, export the staging sitemap and compare it with the current production sitemap.
The Added tab shows exactly which new pages will appear. The Removed tab flags any pages that accidentally dropped off. One comparison, zero surprises.
Monthly SEO reporting. Run a sitemap comparison at the start and end of each month. Export the PDF and include it in your client report. The summary counts and date stamp give you an instant changelog of your site crawlable content, no manual tracking required.
Sitemap index troubleshooting. Large sites often use sitemap indexes with multiple child sitemaps. If a child sitemap goes missing or a new one appears without documentation, the comparison catches it. The three-level recursion means you don't need to inspect each child sitemap manually.
According to Google Search Central, submitting accurate sitemaps is one of the most effective ways to help Google discover your content. A comparison tool ensures your submitted sitemap always reflects your live site accurately.

FAQ
What types of sitemap files does this tool support?
The tool supports standard XML sitemaps and sitemap index files. If a sitemap index is detected, it automatically fetches and parses all child sitemaps recursively up to three levels deep, analyzing up to 500 URLs per sitemap.
Can I enter just a domain name instead of a full sitemap URL?
Yes. Enter a domain like yoursite.com and the tool automatically checks the site robots.txt file for a Sitemap directive. It resolves the sitemap URL and runs the comparison from there.
Why might a sitemap fail to load?
The most common reasons are an incorrect sitemap URL, the file being behind authentication or a firewall, or the server blocking external requests. Make sure the sitemap is publicly accessible and double-check the URL you entered.
What does the CSV and PDF export include?
The CSV export includes all URLs across all three categories with a status column indicating Added, Removed, or Unchanged. The PDF report includes a header with both resolved sitemap URLs, the comparison date, a summary of counts, and the full URL list with status labels.
Is my data private when using this tool?
Yes. Everything runs in your browser. Your sitemap files are fetched client-side, the comparison happens locally, and none of your URL data is sent to any server.
