Common Questions
Logs show exactly how Googlebot crawls your site - which pages it visits, how often, and what errors it encounters. This data is unavailable in other tools.
Request logs from your hosting provider or access them via cPanel, AWS CloudWatch, or similar. Most hosts retain 30-90 days of logs.
Check crawl frequency of important pages, identify wasted crawl budget on low-value URLs, find orphan pages, and spot crawl errors.
