FAQ Section

1. What is AI SEO?

AI SEO, or Generative Engine Optimization (GEO), uses artificial intelligence to analyze data, predict search engine algorithm changes, automate content creation, and optimize strategies at a scale and speed that is impossible for humans alone. It moves beyond keywords to focus on user intent and topical authority.

2. Why is a 'charge-only-after-success' model important?

This model completely aligns the agency's incentives with the client's goals. It demonstrates the agency's confidence in its ability to deliver results and removes the financial risk for the client, making it a powerful indicator of a truly performance-driven service.

3. Do I need a different SEO strategy for Baidu vs. Google?

Absolutely. Baidu and Google have different ranking algorithms, content censorship rules, and user behaviors. Baidu prioritizes its own properties, requires an ICP license for hosting in China, and has a different approach to indexing and technical SEO. A specialized strategy is essential for success.

4. How much should I budget for an AI SEO agency in China?

Costs vary widely. Traditional agencies often charge retainers from $2,000 to $10,000+ USD per month. Disruptive models like PRbyAI's pay-on-success change this calculation, as you only pay for tangible results, shifting the budget from a fixed operational expense to a performance-based investment.
