2. コンテンツエディター
サーファーSEO: The Content Editor is Surfer’s crown jewel. It gives you a Content Score from 0-100 that updates in real-time as you write. The sidebar shows exactly which keywords to add, how many headings to use, and what word count to target.
ライターゼン: Offers a content editor with basic scoring. It analyzes the top 20 search results and shows recommended keywords. The editor highlights which keywords you’ve used but lacks the depth of Surfer’s real-time feedback.
3. SERP分析
サーファーSEO: Analyzes over 500 ranking signals from top pages. You see word count, keyword density, heading structure, backlinks, and content structure. This deep analysis helps you understand exactly what Google rewards.
ライターゼン: Provides a basic summary of the top 20 search results. You see common questions, headings, and word counts. It’s helpful for understanding the landscape but not as detailed as Surfer’s analysis.
4. AI Writing
サーファーSEO: Surfer AI generates full articles optimized for your target keyword. The content is well-structured and ready to publish. You get 5 AI articles on Essential and 20 on Scale plan each month.
ライターゼン: Uses GPT-4o Mini for AI writing assistance. It generates outlines, paragraphs, and full articles. However, the output quality needs more editing compared to Surfer AI. Content length is often shorter.

ライターゼン: The Topic Discovery tool is a standout feature. Enter a seed keyword and get hundreds of related topics 即座に. It shows search volume, competition, and content ideas all in one view.
6. 盗作検出
サーファーSEO: Does not include a built-in plagiarism checker. You’ll need to use a separate tool like Copyscape or 文法 to verify content originality.
ライターゼン: Includes a plagiarism checker that compares your content against Google’s indexed pages. It resets daily and helps ensure your content is original before publishing.
7. チームコラボレーション
サーファーSEO: Scale plan includes up to 10 team seats. You can invite writers, share briefs, and collaborate on content projects. White-label reports are available for agencies.
ライターゼン: Offers unlimited user seats on all plans. The Team Function lets you assign tasks, track progress, and manage freelancers. Great for agencies managing multiple writers.
