**[Important] Regarding AI articles in this survey**
All articles underwent final checks, revisions, and additions by SEO consultants after initial generation by AI. This is not a direct copy-paste output from an AI content generation tool (hybrid model). This survey also includes B2B articles for businesses, including keywords with small search volumes.

## Survey Results Summary

| Indicator | Value |
|---|---|
| **AI Article TOP3 Acquisition Rate** | **51.0%** (2.01 times compared to non-AI) |
| AI Article TOP10 Acquisition Rate | 70.2% (1.25 times compared to non-AI) |
| AI Article TOP30 Acquisition Rate | 84.6% (1.07 times compared to non-AI) |
| AI Article Average Search Ranking | 10.9th place (0.79 times compared to non-AI) |
| AI Article Median Search Ranking | 6.0th place (0.67 times compared to non-AI) |

## Key Findings

**1. AI articles achieve significantly higher TOP3 rankings.**
AI articles achieved a TOP3 ranking rate of 51.0%, which is 2.01 times higher than non-AI articles. This indicates that AI-powered content, when combined with human expertise, can effectively compete for high search rankings.

**2. AI articles show superior performance across all ranking indicators.**
From TOP3 to TOP30 acquisition rates, and average/median search rankings, AI articles consistently outperformed non-AI articles. This suggests that the hybrid model is effective not just for niche keywords but across a broader range of search queries.

**3. The hybrid model (AI + human) is crucial for high-quality, high-ranking content.**
The survey emphasizes that AI-generated content was not published as-is but was refined by SEO consultants. This human oversight ensures accuracy, relevance, and adherence to SEO best practices, which is vital for achieving and maintaining high rankings.

## Background of the Survey

With the rapid advancement of generative AI, there has been increasing interest in its application in content marketing. However, concrete data on the SEO effectiveness of AI-generated content, especially when combined with human expertise, has been scarce. This survey aims to fill that gap by providing transparent, statistically verified data.

## Future Outlook

StockSun Inc. will continue to leverage AI technology to enhance its marketing support services, aiming to provide even more effective and efficient solutions for its clients. The company plans to further refine its hybrid content creation model and explore new applications of AI in SEO and content strategy.
