RankMath: 404, Redirection, and Crawl Optimization

Step 1: Set Up 404 Error Monitoring

Enable RankMath 404 Monitor: WordPress Dashboard → Rank Math → 404 Monitor

Configure 404 Tracking:

• ✅ Enable 404 Monitor: "Track all 404 errors automatically"
• ✅ Log Duration: Set to "30 days" (captures patterns without bloating database)
• ✅ Email Notifications: Enable for critical 404s (over 10 hits)

What You'll See:

• URL: The broken link causing 404s
• Referrer: Where the broken link was found
• Hit Count: How many times it was accessed
• User Agent: Whether it's users or bots hitting the error

Example 404 Report:

Immediate Actions:

• High Traffic 404s (20+ hits): Create redirects immediately
• Low Traffic 404s (1-5 hits): Monitor for patterns
• Bot 404s: Usually ignore unless affecting crawl budget

Step 2: Create Strategic Redirects

Access Redirection Tool: WordPress Dashboard → Rank Math → Redirections

Types of Redirects to Use:

301 Redirects (Permanent):

• When: Content permanently moved
• SEO Impact: Passes 90-95% of link equity
• Example: /old-services/ → /services/

302 Redirects (Temporary):

• When: Temporary maintenance or testing
• SEO Impact: Doesn't pass link equity
• Example: /special-offer/ → /temporary-landing/

Step-by-Step Redirect Creation:

High-Priority Redirects First:

1. Homepage/Main Pages:

2. Service Page Restructure:

3. Blog Category Changes:

Bulk Redirect Import: For multiple redirects, use CSV upload:

Step 3: Fix Broken Internal Links

Identify Broken Links:

Method 1: RankMath SEO Analysis

• Run site-wide SEO analysis
• Look for "Broken internal links" warnings
• Fix directly from the analysis report

Method 2: Manual Content Audit

• Check high-traffic pages for broken links
• Use browser inspect tool to find 404 internal links
• Update links in content editor

Common Broken Link Patterns:

Outdated Service Links:

• Problem: Link to /old-services/implants
• Fix: Update to /dental-implants-chicago
• Action: Search and replace across all content

Changed URL Structure:

• Problem: Links to /blog/2023/post-name
• Fix: Update to /oral-health/post-name
• Action: Bulk find and replace in database

Deleted Page Links:

• Problem: Links to pages that no longer exist
• Fix: Link to most relevant current page or remove link
• Action: Manual review and update

Bulk Link Fixing Process:

1. Export All Content with WordPress export tool
2. Find/Replace URLs in text editor or database
3. Import Updated Content or run SQL update
4. Verify Changes with crawl tool

Step 4: Optimize Site Crawlability

Configure Robots.txt: Access via: Website.com/robots.txt or Rank Math → General Settings → Robots.txt

Essential Robots.txt Rules:

Pages to Block from Crawling:

• Admin pages: /wp-admin/, /dashboard/
• Search results: /search/, /?s=
• Filter pages: /products/?filter=
• Thank you pages: /thank-you/, /confirmation/
• Private content: /members-only/, /internal/

Pages to Prioritize for Crawling:

• Homepage: Most important
• Service/Product pages: High priority
• Blog posts: Medium priority
• About/Contact: Lower priority

Step 5: Improve URL Structure for SEO

Optimize Permalink Structure: WordPress Settings → Permalinks → Custom Structure

Best URL Patterns:

Service-Based Business:

• ✅ Good: /dental-implants-chicago/
• ✅ Good: /emergency-dentist/
• ❌ Bad: /services/dental/implants/chicago/ (too deep)
• ❌ Bad: /p=123 (not descriptive)

Blog Content:

• ✅ Good: /how-to-care-for-dental-implants/
• ✅ Good: /tooth-pain-causes/
• ❌ Bad: /2025/01/15/blog-post-title/ (unnecessary date)
• ❌ Bad: /category/subcategory/post-name/ (too complex)

URL Optimization Rules:

1. Keep URLs Short: Under 60 characters when possible
2. Use Hyphens: Separate words with hyphens, not underscores
3. Include Keywords: Primary keyword in URL
4. Avoid Stop Words: Remove "the," "and," "of" when possible
5. Use Lowercase: Avoid capital letters and special characters

Bulk URL Updates: When changing URL structure:

1. Plan New Structure before making changes
2. Create Redirect Map (old URL → new URL)
3. Update Internal Links to use new URLs
4. Set Up Redirects before changing URLs
5. Monitor for 404s after changes

Step 6: Optimize Site Speed for Crawling

Technical SEO Speed Factors:

Server Response Time:

• Target: Under 200ms server response
• Check: Use Google PageSpeed Insights
• Fix: Optimize hosting, enable caching

Page Load Speed:

• Target: Under 3 seconds full page load
• Impact: Faster sites get crawled more frequently
• Fix: Optimize images, minify CSS/JS, use CDN

Crawl Budget Optimization:

Prioritize Important Pages:

• Ensure homepage loads fastest
• Optimize top service/product pages
• Speed up new content for faster indexing

Remove Crawl Waste:

• Block low-value pages (admin, search results)
• Fix infinite scroll issues
• Prevent parameter-based duplicate pages

RankMath Speed Settings: Rank Math → General Settings → Advanced

• ✅ Enable "Minify CSS output"
• ✅ Enable "Remove query strings from static resources"
• ✅ Enable "Optimize database tables"

Step 7: Advanced Crawl Management

XML Sitemap Optimization:

Sitemap Structure:

Sitemap Best Practices:

• Limit: 50,000 URLs per sitemap file
• Update Frequency: Daily for active blogs, weekly for service sites
• Priority Values: 1.0 for homepage, 0.8 for main services, 0.6 for blog posts
• Last Modified: Always include accurate lastmod dates

Custom Sitemap Rules:

Step 8: Monitor and Fix Crawl Errors

Google Search Console Integration:

Connect GSC to RankMath: Rank Math → General Settings → Search Console

• Enter Google Search Console API key
• Authorize connection
• Enable automatic error reporting

Key Crawl Errors to Monitor:

Server Errors (5xx):

• Problem: Server timeouts, maintenance mode
• Impact: Pages can't be crawled or indexed
• Fix: Contact hosting provider, optimize server performance

Not Found Errors (4xx):

• Problem: Deleted pages, broken links
• Impact: Wasted crawl budget, poor user experience
• Fix: Create redirects or fix broken links

Access Denied (403):

• Problem: Permission issues, blocked content
• Impact: Important content not indexed
• Fix: Check file permissions, update robots.txt

Redirect Errors:

• Problem: Redirect chains, redirect loops
• Impact: Slow crawling, lost link equity
• Fix: Create direct redirects, eliminate chains

Weekly Crawl Health Checklist:

•  Check GSC for new crawl errors
•  Review 404 monitor for patterns
•  Verify sitemap submission status
•  Monitor page speed for top pages
•  Check robots.txt accessibility

Step 9: Advanced Redirect Strategies

Redirect Chain Prevention:

Bad Example (Redirect Chain):

Good Example (Direct Redirect):

Wildcard Redirects: For bulk URL pattern changes:

Conditional Redirects: Based on user agent or referrer:
