What is Rogerbot?
Rogerbot is Moz's specialized crawler designed specifically for their Moz Pro customers to perform detailed site audits. Unlike DotBot which crawls the general web, Rogerbot focuses on deep analysis of specific websites when requested by Moz Pro users. The bot identifies technical SEO issues, crawl errors, duplicate content, and site structure problems. It provides actionable insights for SEO optimization, making it a valuable tool for technical SEO audits. Rogerbot only crawls sites that are explicitly added to Moz Pro campaigns by their owners or authorized users.
