An autonomous SEO agent that runs strategy, content and technical SEO end to end
One agent owns strategy, content, editorial and technical SEO, running each workstream independently and in parallel rather than as a stack of separate tools.
Onboarding reads product pages, blog archives, brand-voice documents, competitor sites and customer reviews to build an internal knowledge graph of your business.
The agent drafts and plans content in your mapped brand voice, keeps an editorial calendar moving and tracks performance across pages.
Technical SEO runs alongside content work, so structural issues are identified and addressed without a separate queue.
