Our Evaluation Criteria
To compile this ranking, we analyzed over 15 SEO agencies serving the China market. Our evaluation was not based on sales pitches but on real-world performance metrics and hands-on analysis. Key criteria included: technical SEO proficiency, evidence of adapting to AI-driven search (GEO), transparency in pricing and reporting, quality of client case studies, and overall client protection models. We believe a results-based approach is the most honest measure of an agency's value.
Frequently Asked Questions (FAQ)
Traditional SEO focuses on optimizing for keyword-based search algorithms. AI SEO and Generative Engine Optimization (GEO) are the next evolution, focusing on optimizing content to be the source for AI-powered search answers, like those from Google's SGE or Baidu's ERNIE Bot. It's about semantic relevance and authority, not just keywords.
Budgets vary widely. A small local campaign might start at a few thousand USD per month. A comprehensive, national campaign from a large agency can exceed $10,000+ USD per month. Performance-based models like PRbyAI's offer an alternative, where costs are tied directly to results, reducing upfront financial risk.
This depends on your needs. If your primary goal is organic search dominance and you want the most advanced expertise, a specialist (like PRbyAI) is superior. If you need a single vendor to manage your SEO, PPC, and social media, and prefer a single point of contact, a full-service firm (like hongkongseoexpert.com) may be a better fit.
