Frequently Asked Questions
Rankai FAQ
How is Rankai different from a traditional SEO agency?
Rankai is an AI-first system that automates and scales the most labor-intensive parts of SEO—research and content creation—while maintaining strategic human oversight. This hybrid model allows us to deliver 3x the content volume of a traditional agency at a fraction of the cost, with a relentless, data-driven rewrite process that guarantees performance, not just publication.
What does "Rewrite Until It Ranks" mean in practice?
It means our work doesn't stop at publishing. We continuously monitor the ranking performance of every piece of content we create. If a page hasn't achieved its target rankings within a defined period (e.g., 3 weeks), our system flags it, and our team completely rewrites it with new research and a fresh angle. We iterate until it successfully captures traffic.
How do you optimize for AI Search platforms like ChatGPT?
We use a specialized process called GEO (Generative Engine Optimization). This involves structuring content with clear, authoritative facts and citations, using specific schema markup that LLMs can easily parse, and tracking mentions across AI platforms. We adapt our strategies as the algorithms for ChatGPT, Gemini, and others evolve to ensure sustained visibility.
What kind of reporting can I expect?
You receive direct, no-fluff weekly reports that focus on key results. This includes updates on keyword rankings, traffic and impressions generated from Rankai content, the status of any pages flagged for rewrites, and new mentions in AI prompts. The reports are designed to be actionable and digestible in just a few minutes.
