Missing from Site (404s)

Overview

“Missing from Site” identifies URLs listed in your sitemap.xml that weren’t found during the crawl. These are typically pages that return 404 errors, have been deleted, or are inaccessible—yet they’re still declared in your sitemap as valid pages.

Sitemap vs Reality
═══════════════════════════════════════════════════════════

sitemap.xml declares:          Actual site returns:
─────────────────────          ────────────────────
/about           ────────────→  200 OK ✓
/products        ────────────→  200 OK ✓
/old-product     ────────────→  404 Not Found ✗
/deleted-page    ────────────→  404 Not Found ✗
/typo-url        ────────────→  404 Not Found ✗
                                    │
                                    └─ These are "Missing from Site"

Why This Matters

Listing non-existent pages in your sitemap causes several problems:

Issue	Impact
Wasted crawl budget	Search engines spend resources on dead pages
Poor indexing signals	Indicates poor site maintenance
Sitemap trust erosion	Search engines may deprioritize your sitemap
User experience	Users following sitemap-based links hit 404s
SEO authority loss	Broken pages can’t pass link equity

Google explicitly recommends only including canonical, 200-status URLs in your sitemap. Including 404s violates their sitemap guidelines and can reduce crawl efficiency.

How We Detect Missing Pages

Our analysis cross-references your sitemap with crawl results:

Fetch Sitemap

We download and parse your sitemap.xml (and any sitemap index files).

Track Crawl Results

During the crawl, we record the HTTP status of every URL encountered.

Match Sitemap URLs

We check each sitemap URL against our crawl results.

Flag Missing Pages

URLs in the sitemap that returned 404, 410, or weren’t reachable are flagged.

Common Causes

1. Deleted Content

Content removed without updating the sitemap:

Timeline:
─────────────────────────────────────────
Jan 1:   /winter-sale created, added to sitemap
Jan 31:  /winter-sale deleted
Feb 15:  Sitemap still contains /winter-sale ← Problem

2. URL Structure Changes

Restructuring URLs without proper cleanup:

Old URL	New URL	Sitemap Status
`/blog/my-post`	`/articles/my-post`	Still lists old URL
`/products/widget`	`/shop/widget`	Still lists old URL
`/about-us`	`/about`	Still lists old URL

3. CMS Migration Issues

Moving between content management systems:

Import errors creating bad URLs
Different URL slug generation rules
Missing content from partial migrations
Draft content included by mistake

4. Auto-Generated Sitemaps

CMS plugins that don’t clean up properly:

WordPress Example:
─────────────────────────────────────────
Plugin auto-adds all posts to sitemap ✓
Post is trashed ✓  
Post is deleted ✓
Sitemap still references post ✗ ← Plugin didn't update

5. Manual Sitemap Errors

Hand-maintained sitemaps with mistakes:

Typos in URLs
Copy-paste errors
Forgotten test URLs
Outdated entries never reviewed

6. Staging/Dev URLs

Test URLs accidentally included:

<!-- These shouldn't be in production sitemap -->
<url>
  <loc>https://example.com/test-page-123</loc>
</url>
<url>
  <loc>https://example.com/staging-preview</loc>
</url>

How to Fix

Step 1: Verify the Issue

First, confirm the pages are truly missing:

Browser Check
curl Check
Bulk Check

Visit each URL directly:

https://example.com/missing-page

Expected: 404 Not Found page

Use command line to verify:

curl -I https://example.com/missing-page

# Look for:
# HTTP/2 404

Step 2: Decide on Action

For each missing URL, choose an approach:

Scenario	Action
Content moved to new URL	Set up 301 redirect, update sitemap
Content intentionally deleted	Remove from sitemap
Content should exist	Restore or recreate the page
URL has typo in sitemap	Fix the URL in sitemap
Duplicate/outdated entry	Remove from sitemap

Step 3: Update Your Sitemap

Remove or fix the problematic entries:

<!-- REMOVE these entries from sitemap.xml -->

<!-- Deleted page - remove entirely -->
<url>
  <loc>https://example.com/deleted-page</loc>
  <lastmod>2024-01-15</lastmod>
</url>

<!-- Moved page - remove old URL (redirect handles SEO) -->
<url>
  <loc>https://example.com/old-url</loc>
  <lastmod>2024-01-15</lastmod>
</url>

<!-- ADD the new location if it moved -->
<url>
  <loc>https://example.com/new-url</loc>
  <lastmod>2024-12-01</lastmod>
</url>

Step 4: Set Up Redirects (If Applicable)

For moved content, configure proper redirects:

Apache (.htaccess)
Nginx
Next.js
Vercel

# Redirect single page
Redirect 301 /old-page /new-page

# Redirect pattern
RedirectMatch 301 ^/blog/(.*)$ /articles/$1

# Single redirect
location = /old-page {
  return 301 /new-page;
}

# Pattern redirect
location ~ ^/blog/(.*)$ {
  return 301 /articles/$1;
}

// next.config.js
module.exports = {
  async redirects() {
    return [
      {
        source: '/old-page',
        destination: '/new-page',
        permanent: true,
      },
    ]
  },
}

// vercel.json
{
  "redirects": [
    {
      "source": "/old-page",
      "destination": "/new-page",
      "permanent": true
    }
  ]
}

Step 5: Regenerate Sitemap

After cleanup, regenerate your sitemap:

CMS	How to Regenerate
WordPress	Use Yoast/RankMath to rebuild
Shopify	Automatic (wait 24-48 hours)
Next.js	Rebuild with `next build`
Static	Run sitemap generator script
Manual	Edit `sitemap.xml` directly

Preventing Future Issues

Automated Sitemap Generation

Use tools that automatically maintain sitemap accuracy:

// Example: Dynamic sitemap generation
export async function generateSitemap() {
  const pages = await getAllPublishedPages() // Only live pages
  
  return pages
    .filter(page => page.status === 'published')
    .filter(page => !page.noindex)
    .map(page => ({
      url: page.url,
      lastmod: page.updatedAt,
    }))
}

Pre-Delete Checklist

Before deleting any page:

Check Inbound Links

Are other pages linking to this URL?

Check Search Rankings

Is this page ranking for valuable keywords?

Set Up Redirect

If valuable, redirect to relevant alternative.

Update Sitemap

Remove the URL from sitemap.xml.

Update Internal Links

Fix any internal links pointing to deleted page.

Regular Audits

Schedule sitemap health checks:

Frequency	Action
Weekly	Automated sitemap validation
Monthly	Manual review of sitemap entries
Quarterly	Full sitemap audit with crawl comparison
After major changes	Immediate sitemap verification

Set up monitoring alerts for sitemap changes. Any significant increase in sitemap size without corresponding content creation could indicate issues.

Interpreting Results

Severity Assessment

Missing Pages	Severity	Recommended Action
0	✅ Excellent	Sitemap is accurate
1-5	🟡 Low	Fix during regular maintenance
6-20	🟠 Medium	Prioritize cleanup this week
20+	🔴 High	Immediate sitemap audit needed

Percentage Threshold

Consider the ratio of missing pages:

Missing Pages: 15
Total Sitemap URLs: 500
Percentage: 3%

Assessment: Acceptable, but should be fixed
Target: < 1% missing pages

False Positives

Some URLs may appear missing but aren’t problems:

Scenario	Explanation
Recently published	Page exists but wasn’t in this crawl
Protected content	Login required, crawl couldn’t access
Rate limiting	Server blocked crawler temporarily
Geo-restricted	Page not available in crawler’s region

If you believe a page is incorrectly flagged, manually verify it exists by visiting the URL directly. Our crawler may have been blocked or rate-limited.

Missing pages often indicate broader problems:

Related Issue	Connection
Orphan pages	May have been orphaned before deletion
Broken internal links	Other pages may link to missing URLs
Redirect chains	Missing pages may be part of broken chains
Index bloat	Old URLs may still be indexed
