What is JetOctopus?
JetOctopus is a high-speed cloud-based SEO crawler designed for technical SEO auditing, log analysis, and crawl data visualization. The bot can crawl large websites quickly to identify technical issues such as broken links, duplicate content, crawl errors, and indexing problems. It provides detailed crawl reports and integrates with server log data for comprehensive SEO analysis. The bot respects robots.txt directives.
