JetOctopus

JetOctopus is a cloud-based SEO crawler designed for large sites. It can crawl up to 10 million pages per project, handles JavaScript-rendered content, and includes log file analysis to see how search bots actually crawl your site. It's built for SEOs who need to find technical issues at scale.

What it does

You enter a URL and JetOctopus crawls the site, identifying broken links, duplicate content, slow pages, redirect chains, and other technical SEO problems. It renders JavaScript to see what search engines see. The log file analyzer shows which pages Googlebot actually visits and how often.
