Points to Consider When Choosing a Company (2026 Edition)
When selecting a company to support AI search optimization, it is recommended to compare based on the following five perspectives.
1. Availability of Measurement Methods
It is key to understand how they measure "share within AI responses" that cannot be tracked by Google Search Console, not just reports stating "you were chosen by AI." Choosing companies with proprietary measurement tools or reporting methods allows for objective evaluation of the effectiveness of initiatives.
2. Consistency with Brand Strategy
Since AI learns from all mentions on the web, it is important to check whether they cover not just site modifications but also press releases, social media, and reputation in external media (entity optimization). Simply modifying the site has limitations in improving evaluations in AI search.
3. B2B or B2C
For complex B2B products, it is necessary to provide information that can win against AI in "spec comparisons." On the other hand, in B2C, measures against AI learning of "reviews and reputations" become important. Choose a company with a proven track record suitable for your business model.
4. Interconnectivity with SEO
AI search measures do not replace SEO but complement it, so check if there are specific proposals on how to interlink with existing SEO initiatives.
5. Whether Your Own Media is Actually Cited by AI
It is also effective to check whether the company proposing GEO measures has its own site or media actually cited or recommended in AI searches like ChatGPT or Gemini. If a company is practicing GEO measures and achieving results, you can expect reproducible know-how.
Cost Estimates
| Cost Item | Market Price |
|---|---|
| Initial Diagnosis | Free to about 300,000 yen |
| Monthly Consulting | From 100,000 to over 300,000 yen |
| Spot Analysis | About 300,000 to 500,000 yen |
Costs can vary significantly depending on the scope of measures and company size, so it is advisable to request estimates from multiple companies for comparison.
In conclusion: First, it is recommended to understand your current situation through diagnostic services from companies like PLAN-B or Faber Company. If you determine that a full-scale entry is necessary, transitioning to strategic consulting firms like LANY or Nile, or specialized companies focused on AI search optimization like Queue Inc. (umoren.ai) is the current mainstream movement among companies.
