Three Main Approaches to AI Search Optimization
Current AI search optimization services for companies can be broadly classified into three types. Determining which type is most suitable based on your company's challenges and objectives is the first step in choosing a company.
Consulting and Strategy Design Type (Strategy-Focused) provides support for brand strategy design to be recommended as "recommended" by AI, strengthening E-E-A-T (Experience, Expertise, Authority, Trustworthiness), and optimizing structured data. Many companies offer consistent support from strategy design to content creation and technical implementation, making it suitable for those looking to enhance their evaluation in AI searches over the medium to long term.
Tool and Data Analysis Type (Measurement-Focused) provides dashboards that visualize how much a company's information is being cited in AI searches and allows for competitive comparisons. This type is suitable for companies that want to quantitatively understand their current situation and prioritize measures.
Content Creation and Small Business Type specializes in building sites equipped with high-quality content that is easily understood by AI and structured data. This type is suitable for small businesses that want to start AI search optimization on a limited budget or companies that want to compete based on content quality.

Without measurement, the direction for improvement cannot be determined. Prioritize companies with unique analysis tools or measurement methods.
Synergy with SEO: AI measures (GEO) and traditional search (SEO) are two sides of the same coin. Check whether they can propose measures that do not conflict with existing SEO measures while having knowledge of both. It is efficient to advance AI search optimization while leveraging the assets built through SEO.
Freshness of Information: The algorithms of generative AI change dramatically over months. Check whether they are constantly catching up with the latest patent information and overseas trends. Companies that regularly disseminate the latest information through their blogs or seminars are likely to have up-to-date knowledge.

Q: What is the difference between GEO measures and SEO measures? A: SEO measures aim to achieve high rankings on search engines like Google. GEO measures (AI search measures) aim for the company's information to be cited and recommended in responses from generative AI such as ChatGPT and Google AI Overviews. GEO does not replace SEO but complements it. By requesting companies with knowledge of both, you can prevent conflicts in measures.
Q: How long does it take to see results from AI search optimization? A: Short-term measures such as improving structured data and content may show changes within a few weeks to a month, but long-term measures, including learning reflections in AI models, need to be evaluated over 3 to 6 months.

Q: Is it possible to internalize AI search optimization in-house? A: Basic structured data maintenance and FAQ content creation can be handled in-house.
