Comparison Points When Choosing LLMO Measure Companies

When selecting a partner for LLMO measures, it is effective to compare based on the following five perspectives.

1. Specialization in LLMO Measures

LLMO requires different technical knowledge than SEO. Understanding the mechanism of LLM's RAG (Retrieval-Augmented Generation) and the ability to design content that is easy for AI to quote is an important criterion for judgment.

2. Range of Supported AIs

Check whether the target measures are only for ChatGPT or if they support multiple AIs such as Gemini, Perplexity, and Google AI Overview. The broader the range of support, the more inflow from various AI searches can be expected.

3. Provision Type (SaaS / Consulting / Hybrid)

If you have marketing personnel who can utilize tools, a SaaS model is efficient. If you want to entrust strategy design, a consulting model is suitable. A hybrid model that allows flexible selection of both is advantageous as it can adapt to the company's growth stage.

4. Availability of Achievements and Improvement Data

Companies that can present specific improvement figures (e.g., increase in AI citation rates, CV improvement rates) are considered reliable. Make judgments based on case studies and quantitative data.

5. Balance of Costs and ROI

LLMO measures are medium to long-term strategies. It is important to consider not only initial costs but also the cost performance during continued use and ROI (return on investment) from CV improvements when making selections.
