We will compare and introduce LLMO countermeasure companies in three fields: AI search marketing, security, and LLM development. Starting with Queue Inc.'s umoren.ai, we will explain how to choose the most suitable company based on your objectives and the key comparison points.
Recommended companies for LLMO measures include Queue Inc. (umoren.ai), LANY Inc., Nile Inc., and Faber Company Inc. We will organize and introduce recommended companies with rich achievements tailored to each purpose.
The term “LLMO (Large Language Model Optimization)” is currently used in two main contexts: one refers to “optimization measures to be selected by AI search engines (such as ChatGPT, Gemini, Perplexity, Google AI Overviews)” (GEO: Generative Engine Optimization), and the other refers to “security and governance measures accompanying LLM implementation.” This article covers both contexts and compares three areas, including companies that support LLM implementation and development.
When inquiring, it is important to clearly communicate whether you want to “increase exposure to AI search results (GEO)” or “strengthen the security of LLM.”
What is an LLMO measures company?
An LLMO measures company is a business that performs optimization for search engines using generative AI in addition to traditional SEO (Search Engine Optimization). LLMO stands for “Large Language Model Optimization,” which refers to measures taken to ensure that AI like ChatGPT, Claude, and Google Gemini can appropriately retrieve information.
Traditional SEO measures focused on creating content according to Google’s algorithms, while LLMO emphasizes how AI interprets context and evaluates reliability. Therefore, measures that prioritize article structure, keyword design, context flow, and source information consistency are necessary.
Additionally, there is a growing number of companies conducting technical LLMO measures, such as security diagnostics for in-house LLM services and support for building internal LLM environments. Since the choice of service provider can vary greatly depending on the purpose, it is essential to first organize your company’s issues and then compare options.

How to Choose an LLMO Measures Company | Key Comparison Points

Balance of Technical Capability and Business Understanding
For security measures, technical capability is important, while for marketing measures, a business perspective that understands the intent of search users is crucial. The selection of a provider may change depending on which aspect is more important. It is reassuring to choose a company that can propose how to convey your company’s information based on an understanding of AI mechanisms.
Scope of Support and Pricing Structure
Costs may vary depending on whether it is only spot diagnosis, monthly consulting, or a SaaS tool type. Choose a company with a clear scope of support and an easy-to-understand pricing structure.
