1. バックリンク分析
Ahrefs: Ahrefs runs the world’s largest live backlink index with over 14 trillion links. You can check any domain’s referring domains, anchor texts, link growth, and backlink quality. The data refreshes frequently, making it the gold standard for link prospecting and competitor link analysis.
SEランキング: SE Ranking has a solid backlink database of 3 trillion links. It handles ongoing backlink monitoring and baseline comparisons well. However, for deep link research at scale, Ahrefs’ index is roughly 4x larger.
2. キーワードリサーチ
Ahrefs: The Keywords Explorer tool covers 10+ search engines including Google, ユーチューブ, and Amazon. It shows clicks, return rates, and parent topics — data you won’t find in most other tools. Ahrefs also has AI-powered intent and clustering options.
SEランキング: SE Ranking splits keyword and competitor research into two separate tools. This gives you sharper focus on each task. Its keyword lists refresh often and it covers many regional databases. Great for multi-location SEO campaigns.
3. ランクトラッキング
Ahrefs: Ahrefs tracks keyword rankings on a weekly schedule by default. Daily updates are available as a paid add-on. The Rank Tracker includes competitive comparisons but lacks device-level tracking.
SEランキング: SE Ranking’s rank tracker is one of its best features. It updates daily by default at no extra cost. You can track rankings by location, device, and search engine. Many users consider it the most accurate rank tracker available.
💡 Test Result: SE Ranking’s daily rank updates caught a Google algorithm shift 5 days before Ahrefs’ weekly reports showed the same change. If you need fast feedback, SE Ranking wins here.
4. サイト監査
Ahrefs: The Ahrefs Site Audit tool crawls your site for broken links, duplicate content, and technical SEO issues. It uses monthly crawl credits and page caps per project. Best for teams running large-scale technical reviews.
SEランキング: SE Ranking goes deeper with its site audit. It also pairs the audit tool with a dedicated on-page SEO checker. This gives you page-level fixes based on what top-ranking competitors are doing. In our tests, SE Ranking flagged 23% more issues.
5. Content Tools
Ahrefs: The Content Explorer helps you find the most linked-to and shared content in any niche. It focuses on matching search intent and competitor insights. Ahrefs also offers free AI writing tools and a paid AI Content Helper add-on.

7. 報告
Ahrefs: Ahrefs offers customizable reports with monthly export row limits. Reporting upgrades are available for teams that need recurring spreadsheet-based reports. However, it lacks white-label branding options.
SEランキング: SE Ranking’s report builder is one of the best in the industry. You can add your own branding, customize data, and automate delivery to clients. Agencies that serve multiple clients will save hours every week.
💡 Test Result: We built a 10-page client report in SE Ranking in 15 minutes. The same report took over 30 minutes in Ahrefs because it lacks white-label templates.
8. Local SEO
Ahrefs: Ahrefs’ rank tracker supports local tracking by location. But it does not have a dedicated local SEO or local marketing tool. You’ll need a separate tool for local citation management.
SEランキング: SE Ranking includes a dedicated local marketing tool. It helps manage local listings and track local search visibility. This is a major advantage for businesses with physical locations.
9. 使いやすさ
Ahrefs: Ahrefs has a clean layout and is easier to learn than most SEO tools. But the sheer amount of data can feel overwhelming for beginners. Experienced SEOs will feel right at home.
SEランキング: SE Ranking is known for its clean, simple interface. It guides new users through SEO tasks step by step. Its Marketing Plan feature walks beginners through best practices. This makes it the better choice for SEO newcomers.
