Introduction
Auditing a 10,000+ page website is fundamentally different from auditing a small site. The scale introduces unique challenges: crawl time, data management, issue prioritization, and resource allocation.
This guide covers strategies, tools, and best practices for auditing enterprise-level websites efficiently and effectively.
Challenges of Large Site Audits
- Crawl time: Large crawls can take hours or days
- Data volume: Managing millions of data points
- Issue volume: Thousands of issues to analyze
- Resource limits: Server, memory, and bandwidth constraints
- Prioritization: Finding needles in haystacks
Pre-Audit Planning
1. Define Scope
Don't try to crawl everything at once:
- Start with main site sections
- Exclude admin/private areas
- Focus on public-facing content
- Use sitemaps to guide scope
2. Set Up Infrastructure
Ensure you have:
- Sufficient crawl capacity (cloud-based crawlers recommended)
- Storage for crawl data
- Processing power for analysis
- Team collaboration tools
3. Configure Crawl Settings
Optimize for large sites:
- Set appropriate crawl depth
- Use sitemap seeding
- Respect robots.txt
- Configure rate limiting
- Set page limits per section
Crawling Strategies
Strategy 1: Sectional Crawls
Break large sites into sections:
- Crawl product pages separately from blog
- Audit category pages independently
- Combine results for analysis
Benefits: Faster crawls, easier to manage, parallel processing
Strategy 2: Incremental Crawls
Crawl in stages:
- Start with homepage and top-level pages
- Expand to category pages
- Finally crawl product/content pages
Benefits: Early insights, progressive analysis, manageable chunks
Strategy 3: Sample-Based Audits
For very large sites (100k+ pages):
- Crawl representative samples
- Focus on high-traffic sections
- Use statistical sampling
Benefits: Faster audits, still representative, actionable insights
Data Management
Cloud Storage
Use cloud-based storage for crawl data:
- Accessible from anywhere
- No local storage limits
- Team collaboration
- Historical tracking
Data Export
Export strategically:
- CSV for spreadsheet analysis
- JSON for programmatic processing
- Filter exports by issue type
- Export subsets for focused analysis
Issue Analysis at Scale
1. Group by Pattern
Identify template-level issues:
- Group issues by URL structure
- Identify common patterns
- Fix templates, not individual pages
2. Prioritize by Impact
Use traffic and business data:
- Focus on high-traffic pages
- Prioritize revenue-critical sections
- Fix widespread issues first
3. Use Automation
Automate where possible:
- Automated issue detection
- Bulk fixes via templates
- Automated reporting
