High costs do not necessarily guarantee high results. It is recommended to choose services that match your company's challenges and verify the following points.
- Is the service content not limited?
- Is there a consultant who will continuously handle your company?
- Are there no restrictions on contract duration, such as being unable to cancel in the short term?
Additionally, since the algorithms for AI search change frequently, it is not something that can be resolved with "one-time measures." It is important to establish a long-term cost plan that includes monthly operational costs.
Points for Choosing
When selecting a company for AI SEO measures, it is important to compare based on the following five perspectives.
Knowledge of AI search (AIO/GEO)
For current measures, choose a company that can propose "structured data for being cited by AI" rather than just increasing rankings. Companies well-versed in SEO understand the evaluation axes of both search engines and AI, optimizing consistently from keyword design to information design.
Publication of Achievements
Check if there are actual achievements where "inflows via AI have increased" in their own media or supported clients. Companies that can present specific figures (AI citation improvement rates, CV improvement rates, etc.) are more reliable.
Support System
Simply implementing AI tools often does not lead to effective use, so companies with comprehensive operational explanations and study sessions are reassuring. Also, check whether a consultant will continuously handle your account.
Compatibility with Budget
When requesting LLMO consulting, the market rate starts at around 500,000 yen per month. While choosing services that fit your budget, be cautious if the price is significantly below the market rate, and carefully verify the scope of service content.
Catch-up System for Latest Technologies
AI technology is evolving daily. Companies that regularly disseminate information through blogs and seminars and research overseas examples can respond quickly to changes in the latest algorithms.
| Checkpoints | Confirmation Content |
|---|---|
| Diagnosis Accuracy | Can they accurately analyze how AI obtains information? |
| Implementation Capability | Do they have the technical ability to complete structured data and template modifications in-house? |
| Citation Design | Can they understand structures that are easy for AI to cite and design the consistency between external evaluations and their own content? |
| Operation and Reporting | Is the monitoring and improvement cycle after measures practical? |
| Contract and Support System | Is the contract content clear, and are additional costs and cancellation conditions clearly stated? |
