1. キーワードリサーチ
セムラッシュ: The Keyword Magic Tool gives access to over 25 billion keywords. You can filter by search volume, keyword difficulty score, and intent type. It also shows keyword ideas, keyword suggestions, and question-based queries. Semrush data covers 142 countries, making it a valuable tool for SEO research across any market.
モズ： Keyword Explorer lets you categorize, prioritize, and compare keywords. It shows search volume, keyword difficulty, and organic CTR estimates. The database is smaller than Semrush, but Moz adds a unique “Priority” score that combines metrics into one number.
2. バックリンク分析
セムラッシュ: The backlink analysis tool identifies toxic links and lets you create disavow files. It tracks new and lost backlinks daily. Semrush maintains its own web index for backlink data, giving you fresh link building insights. It also supports link building strategies by finding new prospects through competitor link profiles. The link building tools include アウトリーチ templates and domain quality scores.
モズ： Link Explorer shows referring domains, page authority, and anchor 文章 distribution. Moz also maintains its own web index. The tool works well as a link building tool, but it lacks the toxic link detection that Semrush offers for technical SEO data.
3. サイト監査
セムラッシュ: The site audit tool crawls up to 100,000 pages on the Pro plan. It flags technical SEO issues like broken links, slow pages, and missing meta tags. Each issue comes with a clear fix recommendation.
モズ： Site Crawl handles on-page and technical SEO issues. The Starter plan crawls 20,000 pages, while the Medium plan reaches 2 million. Moz groups issues by severity, making it easy to prioritize fixes.
4. ランクトラッキング
セムラッシュ: Tracks up to 500 keywords on the Pro plan with daily updates. You can monitor keyword rankings across desktop and mobile separately. The SERP tracker also shows featured snippets and local pack positions.
モズ： The Starter plan tracks 50 keywords. The Medium plan bumps that up to 1,500. Moz offers daily updates and shows keyword tracking data alongside SERP features and competitor rankings.
5. コンテンツマーケティングツール
セムラッシュ: The Content Marketing Toolkit is available on Guru and above. It includes an SEO content template, SEO writing アシスタント, topic research, and content audit tools. This is a major advantage for SEO professionals who need data-driven digital marketing strategies built into their workflow.
モズ： Moz does not include content marketing tools. It has an On-Page Grader for page-level SEO optimization checks, but no content planning or writing tools. You’ll need other SEO tools for content strategy.
⚠️ 警告： Semrush locks the Content Marketing Toolkit behind the Guru plan ($208.33/month). If content tools are your main reason to buy Semrush, budget for Guru from the start.
6. 競合分析
セムラッシュ: Semrush offers deep competitor insights. You can see competitor keyword rankings, backlink profiles, paid ad copy, and traffic estimates. The Market Explorer tool shows market share and audience overlap between domains. These two tools combined help you build digital marketing strategies based on real data from organic search results.
モズ： Moz covers organic competitor analysis. You can compare keyword overlap and backlink profiles between sites. It helps you find a particular keyword your competitors rank for. However, Moz lacks PPC competitor data, Google Ads campaigns insights, and traffic estimation tools.
7. ローカルSEO
セムラッシュ: Local SEO is available as a paid add-on at $30/month. It covers listing management and local rank tracking. Not included in the base plans.
モズ： Moz includes a local citation checker in its core plans. It helps businesses manage and clean up local listings. This is a strong point for local SEO needs without paying extra.

モズ： Starting at $39/month, Moz has a much lower entry point. The free version adds extra appeal for budget-conscious users. However, you’re getting fewer tools overall since Moz only covers SEO.
