Why Are Duplicate URLs Appearing in My Sitemap?
Understanding the root cause of duplicates saves you from constantly fighting the same issues. Here are the most common reasons your sitemap may have duplicate URLs:
- Trailing slash inconsistencies: URLs like
example.com/page/andexample.com/pageappear as two separate entries. - WWW vs. non-WWW: Both
www.example.comandexample.comversions included in the sitemap. - HTTP vs. HTTPS: Mixed protocol versions listed separately.
- Pagination mishaps: Paginated pages incorrectly listed multiple times or duplicated with parameters.
- Session IDs and tracking parameters: URLs containing dynamic session IDs or UTM codes get counted as different pages.
- CMS quirks: Some content management systems generate multiple URL variants unintentionally.
- Sitemap generation misconfiguration: Tools may not filter for canonical URLs, resulting in duplicates.
Knowing these helps you address the real issue behind the symptom.

Forget tedious manual scanning. Harness the power of spreadsheet functions to instantly identify duplicates in minutes.
Step 1: Get Your Sitemap URLs
- Download your sitemap XML file from
https://yourwebsite.com/sitemap.xmlor your CMS. - Extract the URLs listed inside
<loc>tags. - Paste these URLs into a single column in Google Sheets or Microsoft Excel.
Step 2: Use UNIQUE and COUNTIF Functions
- In a new column, use
=UNIQUE(A:A)(replace A with your URL column) to get a list of all unique URLs. - Next to each URL, use
=COUNTIF(A:A, A2)to count how many times it appears. - Filter to show only URLs with a count greater than 1 — those are your duplicates.
Step 3: Review and Prioritize
- Sort your duplicates by frequency to identify the biggest offenders.
- Export the list or highlight duplicates for easy review and fixing.
This approach scales for large sitemaps and ensures accuracy without extra software.
How to Prevent Duplicate Pages from Getting into Your Sitemap
Stop wasting time fixing the same duplicates. Build a proactive strategy:
- Check your CMS settings: Ensure it doesn’t generate multiple URL versions by default.
- Implement canonical tags correctly: Signal your preferred URL version on every page.
- Configure sitemap tools: Make sure they include only canonical URLs, avoiding duplicates.
- Schedule regular crawls: Use tools like Screaming Frog to catch duplicates early.
- Standardize URL formats: Force HTTPS, decide on www vs. non-www, and consistent trailing slash usage.
- Exclude session and tracking parameters: Filter these out when generating sitemaps.
Regular maintenance protects your crawl budget and keeps your site healthy.
What Is a Canonical URL?
A canonical URL is the definitive version of a webpage when multiple URLs have similar or duplicate content. Adding a canonical tag tells search engines which URL to index and rank, consolidating link equity and preventing ranking dilution.
What Is Crawl Budget?
Crawl budget is the number of pages search engines will crawl on your site within a given timeframe. Duplicate URLs waste this budget, meaning important pages may get overlooked, reducing your site’s SEO effectiveness.
