How to Fix a Broken XML Sitemap

An XML sitemap is a roadmap for search engine crawlers — it lists your pages, their last-modified dates, and their priority. When the sitemap is broken, crawlers waste budget on errors or cannot discover pages at all. A clean sitemap speeds up indexing, especially for large sites or pages with few internal links. This guide walks through diagnosing and fixing every common sitemap problem.

Step 1: Find your sitemap URL

Check these locations in order:

1. Common paths — /sitemap.xml, /sitemap_index.xml, /sitemap/
2. robots.txt — Open /robots.txt and look for a Sitemap: directive:

Sitemap: https://izajulhaque.com/sitemap.xml

3. CMS settings — WordPress with Yoast: /sitemap_index.xml. Shopify: /sitemap.xml. Webflow: /sitemap.xml.
4. Google Search Console — Check the Sitemaps report to see what sitemaps Google has on record.

If you have no sitemap at all, generate one using your CMS SEO plugin (Yoast for WordPress, or built-in for Shopify and Webflow) or a sitemap generator tool.

Check your sitemap now — Use the XML Sitemap Validator to validate any sitemap URL: it checks XML syntax, URL status codes, and common errors in one pass.

Step 2: Validate the XML structure

A sitemap must be valid XML. Open the sitemap URL in a browser — browsers show an XML parse error message if the structure is broken. Common XML errors and fixes:

Unencoded special characters in URLs:

<!-- Wrong: ampersand breaks XML -->
<loc>https://example.com/page?a=1&b=2</loc>

<!-- Correct: encode the ampersand -->
<loc>https://example.com/page?a=1&amp;b=2</loc>

Wrong or missing namespace declaration:

<!-- Required at the top of every sitemap -->
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://izajulhaque.com/</loc>
    <lastmod>2026-09-15</lastmod>
  </url>
</urlset>

Invalid lastmod date format:

<!-- Wrong: not ISO 8601 -->
<lastmod>September 15, 2026</lastmod>

<!-- Correct: ISO 8601 format -->
<lastmod>2026-09-15</lastmod>

Sitemap index file format (for large sites):

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://izajulhaque.com/sitemap-posts.xml</loc>
    <lastmod>2026-09-15</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://izajulhaque.com/sitemap-pages.xml</loc>
    <lastmod>2026-09-15</lastmod>
  </sitemap>
</sitemapindex>

Step 3: Check for non-200 URLs

Every URL in the sitemap should return an HTTP 200 status. Use the XML Sitemap Validator to check status codes. For each non-200 URL:

Do not list redirect URLs in the sitemap — list the final destination URL. Sitemaps with many 301s waste crawl budget on redirects when the crawler could be sent directly to the final URL.

Step 4: Remove noindex and blocked URLs

A sitemap should only list pages you want Google to index. Remove:

• Pages with <meta name="robots" content="noindex"> — listing a noindex page in the sitemap sends a contradictory signal
• Pages blocked by robots.txt Disallow — listing a crawl-blocked page in the sitemap is also contradictory
• Duplicate pages with a non-self canonical — if page A canonicals to page B, only page B should be in the sitemap
• Admin, login, or private pages — these should be blocked in robots.txt and absent from the sitemap

To check for noindex conflicts, view source on each page and search for noindex. Use the robots.txt checker to verify which paths are blocked. See how to configure robots.txt correctly for robots.txt guidance.

Step 5: Fix URL protocol and domain inconsistencies

All sitemap URLs must match your preferred domain exactly:

<!-- Wrong: mixing http and https, www and non-www -->
<loc>http://izajulhaque.com/services/seo</loc>
<loc>https://www.izajulhaque.com/services/aeo</loc>

<!-- Correct: consistent https, no www (or consistently with www) -->
<loc>https://izajulhaque.com/services/seo</loc>
<loc>https://izajulhaque.com/services/aeo</loc>

The URLs in the sitemap must match your canonical tags exactly. A sitemap listing https:// while canonical tags use http:// creates conflicting signals. See how to set up canonical tags correctly for canonical tag guidance.

Step 6: Submit the fixed sitemap in Search Console

After fixing all errors:

1. Go to Google Search Console → Sitemaps
2. Enter your sitemap URL and click Submit
3. Also submit to Bing Webmaster Tools → Sitemaps
4. Monitor the Sitemaps report over the following 48-72 hours
5. Check Coverage → Excluded for any pages that fail to index despite being in the sitemap

Google Search Console will report the number of URLs submitted vs discovered vs indexed. A large gap between submitted and indexed means pages are being excluded — check the Coverage report for the reason (noindex, canonical issues, crawl errors).

Common mistakes

• Including redirect URLs in the sitemap — Sitemaps should list the final destination URLs, not URLs that redirect to them. Every 301 in the sitemap wastes crawl budget on an unnecessary hop. Update each entry to the final URL.
• Including noindex pages in the sitemap — This sends contradictory signals: "include this page" (sitemap) vs "do not index this page" (noindex tag). Google will usually follow the noindex but the contradiction wastes crawl budget and confuses the signal.
• Not updating the sitemap after adding or removing pages — A sitemap that does not reflect the current state of the site is worse than no sitemap — it directs crawlers to pages that do not exist and omits pages that do. Regenerate the sitemap whenever significant pages are added or removed.
• Setting lastmod to today for all pages on every build — This causes Google to repeatedly recrawl unchanged pages. Only update lastmod when the page content genuinely changes.
• Forgetting to submit after fixing — Fixing the sitemap file is not enough. Resubmit in Google Search Console and Bing Webmaster Tools so the engines pick up the corrected version. Use the XML Sitemap Validator after every significant change.
