Backlink Analysis
This is where Ahrefs truly shines. Its backlink index is the largest and most frequently updated in the industry, crawling over 8 billion web pages daily. Site Explorer provides a comprehensive view of any domain’s backlink profile, referring domains, anchor texts, and link growth over time.
Moz’s Link Explorer is competent and benefits from the universally recognised Domain Authority metric. However, its index is smaller and updates less frequently. For serious link building and competitor analysis, most SEO professionals prefer Ahrefs.

Keyword Research
Ahrefs’ Keywords Explorer covers 10 different search engines including Google, YouTube, Amazon, and Bing. It provides detailed metrics like Traffic Potential (not just search volume), Clicks data, keyword difficulty, and SERP analysis. The parent topic feature helps identify the main keyword to target.
Moz’s Keyword Explorer is simpler but highly accurate. The Priority score (combining volume, difficulty, and CTR) is genuinely useful for prioritisation. For sheer depth and volume of keyword data, Ahrefs wins — but Moz is perfectly adequate for most keyword research needs.

Content Explorer
Ahrefs’ Content Explorer is a unique competitive advantage. It indexes over 1 billion web pages and lets you search for any topic to find the best-performing content by backlinks, organic traffic, or social shares. It’s an invaluable tool for content ideation and link prospecting.
Moz Pro has no direct equivalent to Content Explorer, which is a notable gap for content marketers.
Site Audit
Ahrefs’ Site Audit features JavaScript rendering, which means it can crawl and analyse JavaScript-heavy websites accurately. It’s detailed, fast, and provides actionable recommendations with clear priority scores.
Moz Pro’s site crawl is solid for identifying common technical issues and is particularly beginner-friendly in how it presents findings. It covers the core bases well, though it lacks JavaScript rendering and some of the depth that Ahrefs offers.
