How to Choose an LLMO Measures Company: Checkpoints

When selecting an LLMO measures company, it is important to compare and consider based on the following points.

Is there empirical data on AI searches?

Whether the company has a track record of increasing AI citation rates is the most important criterion. Companies that disclose specific figures (improvement range of citation rates, number of articles handled, etc.) are considered reliable.

Ability to implement structured data

Whether the company can design and implement markup (schema.org / JSON-LD) that is easily understood by AI affects the quality of technical measures. Check if they can also handle site structure renovations.

Track record of enhancing expertise and authority (entities)

To gain trust from AI, enhancing entities is essential. LLMO may require measures that delve into "creating brand value and enhancing entities," so choose a company with expertise in this area.

Range of supported AI

Check if they support multiple AI searches such as ChatGPT, Gemini, Claude, Perplexity, and Google AI Overview. If they only support specific AIs, you may miss exposure opportunities.

Support system and flexibility

Companies that start with current situation investigations and analyses after the initial consultation, and those that prioritize issues and propose accordingly, are trustworthy. It is also important to see if they communicate honestly about requests that may be difficult to accommodate.
