Best Practices

Professional recommendations for optimal robots.txt configuration and WordPress SEO.

Core Principles

1. Start Conservative, Optimize Gradually

Begin with safe settings:

✅ **Initial Setup**:
- Allow major search engines
- Keep default WordPress protections
- Set moderate crawl delay (1 second)
- Monitor before adding restrictions

Advanced optimization comes after understanding your specific needs and traffic patterns.

2. Monitor Before Blocking

Before blocking bots:

1. Analyze current traffic: Use server logs to see who's crawling
2. Check benefits: Some "bad" bots might provide value
3. Test gradually: Block one category at a time
4. Monitor impact: Watch SEO metrics after changes

3. Balance SEO vs. Performance

Optimal balance:

✅ **SEO Priority**:
- Allow search engine bots
- Ensure sitemaps accessible
- Don't block important content

✅ **Performance Priority**:
- Set appropriate crawl delays
- Block unnecessary parameters
- Use physical files when beneficial

Search Engine Best Practices

Major Search Engine Guidelines

Google Recommendations:

• ✅ Allow important content
• ✅ Don't block CSS/JS files
• ✅ Keep sitemats accessible
• ❌ Don't use robots.txt for security (use authentication instead)

Bing Recommendations:

• ✅ Clean, simple rules
• ✅ Allow crawling of important pages
• ✅ Use crawl-delay for large sites
• ❌ Avoid over-blocking

Recommended Search Engine Settings

# Optimal search engine configuration
User-agent: *
Allow: /wp-admin/admin-ajax.php
Allow: /*.css$
Allow: /*.js$
Allow: /wp-content/uploads/

# Allow all major search engines
User-agent: Googlebot
Allow: /

User-agent: Bingbot
Allow: /

User-agent: Slurp
Allow: /

# Set reasonable crawl delay
Crawl-delay: 1

Crawl Budget Optimization

High-Traffic Sites

For sites with 100K+ pages:

✅ **Crawl Budget Strategy**:
- Crawl delay: 2-3 seconds
- Block parameter-heavy URLs
- Prioritize important content
- Use physical file generation

Examples of URLs to block:

# Crawl budget optimization
Disallow: /search/
Disallow: *?s=*
Disallow: *?p=*
Disallow: */feed/
Disallow: */page/
Disallow: */trackback/
Disallow: *?utm_*
Disallow: *?preview=*

E-commerce Sites

Product catalog optimization:

✅ **E-commerce Priorities**:
- Allow: Product pages, categories
- Block: Cart, checkout, account pages
- Block: Filter and sorting parameters
- Optimize: Product image crawling

WooCommerce optimization:

# E-commerce crawl efficiency
User-agent: *
Allow: /products/
Allow: /product-category/
Disallow: /cart/
Disallow: /checkout/
Disallow: /my-account/
Disallow: /*?orderby=*
Disallow: /*?filter=*
Disallow: /*add-to-cart=*

Content Sites

Blog/news site optimization:

✅ **Content Site Strategy**:
- Allow: All content pages and categories
- Block: Archive pagination beyond reasonable limits
- Optimize: Author page crawling
- Allow: Media file indexing for images

Security Considerations

What robots.txt Can Protect

Effective protections:

• ✅ Prevent accidental indexing of admin areas
• ✅ Reduce server load from unwanted crawlers
• ✅ Block known malicious bots
• ✅ Manage crawler bandwidth usage

What robots.txt Cannot Protect

Limited security:

• ❌ Does not provide actual security
• ❌ Bots can ignore robots.txt
• ❌ Doesn't protect sensitive data
• ❌ Not a replacement for proper authentication

Recommended Security Practices

Layer security approach:

1️⃣ **Robots.txt**: First line of defense for well-behaved bots
2️⃣ **Authentication**: Password protection for admin areas
3️⃣ **Firewall**: Block malicious IPs and patterns
4️⃣ **Monitoring**: Log analysis for suspicious activity

Admin area protection:

# Complementary security measures
User-agent: *
Disallow: /wp-admin/
Disallow: /wp-login.php

# But also use:
# - Strong passwords
# - Two-factor authentication
# - IP restrictions
# - Firewall rules

Performance Optimization

Physical vs Virtual Files

Choose based on needs:

Virtual robots.txt (Default):

✅ **Pros**: Easy to update, no file permissions needed
✅ **Use cases**: Small/medium sites, shared hosting
❌ **Cons**: Slight server overhead

Physical robots.txt (Pro):

✅ **Pros**: Better performance, CDN friendly
✅ **Use cases**: High-traffic sites, CDNs, enterprise
❌ **Cons**: Requires file permissions

Crawl Delay Best Practices

Recommended delays by server type:

🖥️ **Shared Hosting**: 1-2 seconds
   - Limited resources
   - Multiple sites on server

🖥️ **VPS**: 0.5-1 seconds
   - Dedicated resources
   - Better performance

🖥️ **Dedicated**: 0.5 seconds
   - High-performance servers
   - Can handle more requests

🛒 **E-commerce**: 2+ seconds
   - Resource-intensive operations
   - Database-heavy pages

Content Strategy Alignment

Content-Based Rules

Different content types need different approaches:

Blog/Public Content:

# Encourage full indexing
User-agent: *
Allow: /blog/
Allow: /articles/
Allow: /news/
Allow: /wp-content/uploads/

Protected/Membership Content:

# Block crawler access to paid content
User-agent: *
Disallow: /members-only/
Disallow: /premium-content/
Disallow: /courses/premium/

Admin/Internal Content:

# Always block administrative areas
User-agent: *
Disallow: /wp-admin/
Disallow: /admin/
Disallow: /internal/
Disallow: /private/

Seasonal/Temporary Content

Managing time-sensitive content:

# Temporary maintenance blocks
User-agent: *
Disallow: /maintenance/
Disallow: /coming-soon/
# Remember to remove after launch!

# Seasonal content management
User-agent: *
Allow: /holiday-2024/
Disallow: /holiday-2023/
