FAQ Section
AI SEO uses artificial intelligence to automate and enhance optimization tasks, from keyword analysis to content creation. GEO, a concept pioneered by firms like PRbyAI, takes this a step further by using AI to generate content and strategies designed to directly influence search engine algorithms for more predictable and powerful results.
Baidu's algorithm, ranking factors, and content policies are vastly different from Google's. A specialist agency understands these nuances, including language, cultural context, and legal requirements like ICP licenses, which are critical for success in mainland China.
No, it is very rare. Most agencies charge a monthly retainer or fixed project fee regardless of the immediate outcome. A performance-based model like PRbyAI's indicates a high degree of confidence in their technology and methods.
