How to Choose the Right AI Search Partner: 3 Critical Factors
Because it is "outsourced," choosing a partner should be done carefully. Be sure to check the following three points.
- Do they have specific achievements in "citation acquisition"?: Rather than just SEO ranking improvements, confirm if they can present actual cases where they were cited in responses on "Google SGE or Perplexity." It is best to ask for specific captures or reports.
- Do they have the technical capability to analyze LLM behavior?: Choose a company that can technically analyze AI learning models such as structured data, knowledge graphs, and vector searches, rather than relying on the philosophy of "writing high-quality articles is enough." The presence or absence of "real machine verification" is a key criterion.
- Quality and transparency of reporting: Ideally, choose a company that can demonstrate "how citations have changed due to which measures, on which AI engines" with data, rather than just reporting "how many articles were submitted." Also, check the reporting system during regular meetings.
What to Expect: Costs and Timeline for AI Search Optimization
Here, we will explain the cost and timeframe estimates for outsourcing measures to specialized companies.
Cost Estimates
Costs can vary significantly depending on the scope of work requested, but the general market rates are as follows:
- Analysis/Strategy Plan (Monthly 200,000 yen～): Requesting competitive research and direction formulation for measures.
- Standard Plan (Monthly 300,000 yen～500,000 yen): Includes strategy, content production, and basic technical measures.
- Premium Plan (Monthly 600,000 yen～): Full outsourcing where everything is completely handed over. Experts act as your company's representatives.
Timeframe for Results
Compared to traditional SEO measures that take 6 months to over a year, GEO/AIO measures tend to show results relatively quickly. Generally, initial results such as an increase in citations in AI responses or mentions of the brand name can be seen in about 3 to 6 months.
FAQ: AI Search Optimization (GEO/AIO) Services
Q. Will our company's specialized knowledge be reflected even if we outsource generative AI search strategies?
A. Yes, the better the company, the more they emphasize initial hearings. Services like umoren.ai thoroughly inquire about your unique data, strengths, and brand voice at the beginning, transforming them into formats (structured data and knowledge panel information) that are easy for AI to learn, ensuring accurate and appealing information is conveyed to AI.
Q. What is the difference between traditional SEO companies and generative AI search strategy companies?
A. The targets and goals of optimization are fundamentally different. SEO companies aim to improve "Google search rankings," while generative AI search strategy companies aim to acquire "citations and recommendations from multiple AI engines." Therefore, a technical approach that understands the learning mechanisms of LLMs is essential.
Q. Are there any preparations that the client should make when outsourcing?
A. There are two points. The first is "documents that articulate your company's strengths and expertise." This is to clarify what you want AI to learn. The second is "sharing the ultimate business goals (KGI)." By sharing what you want to achieve as a result of increasing citations (e.g., more inquiries, enhanced brand recognition), the precision of the measures will improve.
Your Ideal Partner for AI Search Success
Generative AI search strategies (GEO/AIO) are now an indispensable marketing measure. However, due to their high level of specialization, there are limits to what can be handled in-house.
