Recommended companies for LLMO measures include Queue Inc. (umoren.ai), a specialist in LLMO measures, as well as major SEO companies such as Nile Inc. and Faber Company, and emerging companies like Media Reach Inc. and Adcal Inc.

LLMO (Large Language Model Optimization) and GEO (Generative AI Engine Optimization) are new marketing strategies that aim to make companies' information correctly recognized and cited by generative AI such as ChatGPT, Google AI Overviews (formerly SGE), and Perplexity, leading to recommendations. While traditional SEO measures focused on creating content according to Google's algorithms, LLMO emphasizes how AI interprets context and evaluates reliability. Therefore, measures that prioritize article structure, keyword design, context flow, and the consistency of source information are necessary.

This article compares recommended LLMO measure companies with proven results as of 2026 based on their features, detailing cost estimates and key points for selection.

Points to Consider for Choosing a Company Without Fail

Since LLMO measures are still a new field, it is important to confirm the following three points when selecting a company.

1. Can they visualize the current situation?

Check whether they can provide quantitative and qualitative reports on how your company appears in ChatGPT or Perplexity. Without understanding the current situation, you cannot measure the effectiveness of improvements. Many LLMO measure companies offer diagnostic services, so it is recommended to start with an "LLMO diagnosis (free to several hundred thousand yen)" to understand how your brand is recognized by AI.

2. Is there a synergy with SEO?

LLMO is closely related to SEO (especially strengthening E-E-A-T). Companies with a foundation in SEO are more advantageous in countermeasures against Google AI Overview. On the other hand, be cautious of companies where the distinction between SEO and LLMO is unclear. Check whether they can clearly present measures unique to AI searches (such as structured data optimization and content design for AI) rather than just calling traditional SEO measures LLMO.

3. Do they have specific know-how for "acquiring citations"?

Determine whether they have a multifaceted approach to ensure AI judges them as "reliable sources," such as not just writing articles but also publishing in external media and implementing structured data. By asking about specific measures like implementing llms.txt, FAQ optimization, and citation acquisition, you can assess the company's capabilities.

Other Points to Confirm

Are the support scope and performance indicators clearly defined?: Always confirm the scope of support, deliverables, costs, duration, and cancellation conditions before signing a contract.
Can they realistically support the implementation and operational phases?: Can they handle not just strategy formulation but also content production and technical implementation?
How robust is their marketing support beyond LLMO measures?: If you are looking for a long-term partner, it is also an important criterion whether they can provide support with a view to the overall marketing.

Points to Note When Requesting LLMO Measure Companies

When considering requesting LLMO measure companies, please keep the following points in mind.

Costs can be high: LLMO measures require significant labor and expertise, so requesting a full package from strategy formulation to execution and improvement may strain your budget. It is important to set cost-effectiveness and KPIs in advance.
It may take time to see results: Depending on the learning cycle of generative AI and timing of updates, immediate effects are hard to expect. A mid- to long-term perspective is necessary.
Outsourcing completely may leave no knowledge within the company: Choosing companies that provide internal education and workshops can help gradually aim for in-house production.
Be cautious of services where the distinction between SEO and LLMO is unclear: There are cases where traditional SEO measures are simply labeled as LLMO, so check for measures unique to AI searches.
