To spot crawl waste in server logs, use a log analysis tool that lets you identify:
- Bots hitting low-value URLs
- Repeated crawling of duplicate or parameterized pages
- 404s, 5xxs, redirects, and soft-404s
- Pages crawled often but rarely changed
- Crawl activity by user-agent, status code, and URL pattern
Good options include:
Common tools
- Screaming Frog Log File Analyser — very popular for SEO crawl analysis
- Oncrawl — good for large sites and detailed bot/crawl reporting
- Botify — strong for enterprise-level log analysis
- Splunk / ELK stack (Elasticsearch, Logstash, Kibana) — flexible if you want custom dashboards
- GoAccess — lightweight and fast for quick log summaries
What to look for in the logs
Focus on:
- Googlebot/Bingbot requests
- URLs with lots of hits but little value
- Parameter URLs like
?sort=,?filter=,?session= - Infinite spaces like calendar pages, facets, internal search results
- Redirect chains
- Non-200 responses
- Thin or duplicate pages
- Crawl frequency vs. page importance
Best simple workflow
- Parse logs by bot user-agent
- Filter to 200/3xx/4xx/5xx
- Group by URL pattern
- Compare crawl volume to organic value or indexed priority
- Flag pages that are crawled often but shouldn’t be
If you want, I can also give you:

- a step-by-step process,
- or a list of regex patterns to detect crawl waste in logs.
