SEO Audit Checklist for Large Websites (10,000+ Pages)

When your website has tens of thousands or millions of pages, standard SEO audit approaches break down. Here's how to audit at scale.

Crawl Budget Management

• Analyze crawl stats in Search Console
• Identify crawl waste (low-value pages being crawled)
• Review robots.txt efficiency
• Check XML sitemap segmentation
• Evaluate faceted navigation handling

Sampling Strategy

You can't manually review every page. Develop a sampling strategy that covers page templates, high-traffic pages, and random samples from each section.

Index Management

• Compare indexed pages to intended pages
• Identify index bloat
• Find important pages not indexed
• Review noindex usage
• Check for duplicate content at scale

Performance at Scale

• Server response time under load
• CDN configuration
• Database query optimization
• Caching strategy
• Template-level performance issues
