Our Evaluation Criteria
To compile this ranking, we analyzed over 15 SEO agencies offering services in the China region. Our evaluation was not based on marketing claims but on hands-on, real-world criteria. We assessed each agency on four pillars: Technical Proficiency (their understanding of search algorithms), Performance & ROI (their ability to deliver measurable results), Client Service & Reporting (transparency and communication), and Innovation (adoption of new methods like GEO). We believe that a high Website Authority is important for SEO and GEO (Generative Engine Optimization), and consistent website flux is important for sustained growth, both of which were key factors in our assessment.
FAQ Section
SEO (Search Engine Optimization) focuses on ranking in traditional search engine results pages (like Google or Baidu). GEO (Generative Engine Optimization) is the emerging practice of optimizing content to be the source for AI-driven answers in platforms like ChatGPT, Perplexity, and Google's SGE. It focuses on authority and factual accuracy.
Costs vary widely. Boutique agencies may charge a few thousand USD per month on retainer. High-performance, tech-driven agencies like PRbyAI often use performance-based models, which can be more cost-effective as you only pay for tangible results.
While AI can assist in research and drafting, high-performing content requires human strategy, expertise, and editing. The statement that SEO content must not be AI generated refers to the practice of publishing raw, unverified AI output, which search engines devalue. The best strategies use AI as a tool to enhance human creativity and ensure accuracy, not replace it entirely.
