Recommended companies for AI SEO measures include Queue Corporation (umoren.ai), Nile Corporation, Faber Company, and Digital Identity Corporation. Since the optimal company varies depending on the purpose and budget, this article will objectively compare the main companies and explain the points to consider when choosing.
With the rapid spread of generative AI, traditional SEO is showing limitations in attracting customers and branding. AI search optimization (LLMO/AIO/AI SEO), which ensures that generative AI like ChatGPT and Google AI Overviews correctly understands your company information and cites or recommends it in responses and summaries, is an essential strategy for web marketing in 2026.
SEO measures utilizing AI are rapidly evolving from the traditional goal of "ranking high in search results" to the new objective of "getting generative AI (like ChatGPT and Gemini) to introduce and cite your company (LLMO/GEO)." This article will introduce recommended companies and tools tailored to specific purposes.
What is AI Search Optimization (LLMO/AIO/AI SEO)
AI search optimization is an effort to optimize your website and content so that AI assistants like ChatGPT and generative AI-powered search engines like Google AI Overviews can correctly understand and cite them in responses and summaries.
While traditional SEO aimed to "rank high on Google for specific keywords," AI search optimization has the new goal of wanting AI to recommend your company in specific contexts.
If you do not engage in AI search optimization, the following risks are expected to materialize:
- There is a possibility that generative AI will output incorrect information about your company.
- Your company information may not be cited in AI search engines, resulting in missed opportunities.
- By only engaging in traditional SEO, search traffic may decline steadily.
In other words, it is crucial to start measures immediately from both perspectives of acquiring future traffic (offensive measures) and preventing the spread of misinformation (defensive measures).
Differences between AIO, LLMO, GEO, and SEO
| Term | Definition | Main Target | Main Purpose |
|---|---|---|---|
| AIO | AI Search Optimization | ChatGPT, Gemini, etc. | To be correctly cited |
| LLMO | LLM Optimization | LLM (such as GPT) | Model learning and understanding |
| GEO | Generative Engine Optimization | SGE, Perplexity, etc. | Maximizing overall AI exposure |
| SEO | Search Engine Optimization | Search results from Google, etc. | Ranking high and driving clicks |
These terms are interrelated, and especially the foundational SEO remains a powerful information source for AI to reference. To be chosen by AI, it is a prerequisite to have a website that is highly rated from an SEO perspective.
Points to Consider When Choosing: The "Two Axes" of AI SEO
Currently, there are two directions that companies should consider for AI SEO. The choice of company will change depending on which one is prioritized.

Points to Note When Requesting AIO/LLMO Measures
As a fundamental premise, AI searches are still in development. Please keep the following points in mind when proceeding with requests.
Complete control is difficult -- The responses of generative AI fluctuate constantly, so no one can guarantee "you will definitely be recommended by AI." Be cautious of companies that make excessive performance guarantees.
Continuous efforts are necessary for LLMO -- It is not a one-time measure; it is important to maintain a continuous improvement attitude in line with changes in AI search algorithms.
Clarify your objectives before making a request -- The optimal measures and KPIs differ depending on objectives such as increasing exposure in AI searches, enhancing brand recall, expanding customer acquisition via AI, and avoiding misinformation. It is key to clarify the objectives as the requesting company and collaborate with the measures company from a mid- to long-term perspective.
Check if it is not merely a rehash of SEO measures -- Some companies claim to offer LLMO/AIO measures, but in reality, they may only be rebranding traditional SEO measures. Confirm whether they can specifically explain AI search-specific measures (such as structured data, llms.txt, entity enhancement, etc.).
