How Ahrefs Stands Out from Semrush

Gain in-depth competitor analysis—from broad market insights to detailed page-level updates. Not just basic overviews.

Site Explorer

Analyze up to 10 competitors at once, instead of being limited to five.

The Performance chart allows you to review as many as 10 competitors across metrics like Organic Traffic, Referring Domains, Share of Voice (SOV), and more.

Semrush restricts competitor comparisons to five and offers SOV only in its highest pricing plan.

Only with Ahrefs

Measure how frequently competitors are cited in AI search, not just referenced.

Identify which sections of competing websites generate the most organic traffic, backlinks, and paid ads.

Discover competitors’ top-performing pages, monitor their progress, and detect when content updates occur.

Track major messaging shifts and view the exact content edits that result in traffic increases or declines.

AI Tools

AI designed to deliver meaningful results—not distractions.

Monitor brand visibility across AI search platforms and large language models (LLMs).

Enhance international performance with AI-driven localization.

Content Marketing

Develop high-performing content using detailed, actionable insights—not just keyword suggestions.

AI Content Helper

Focus on topical authority instead of keyword overuse.

AI Content Helper improves your writing with topical scoring, SERP data, and AI chat to quickly identify content gaps.

In contrast, Semrush’s optimization tool emphasizes keyword density, and its AI chat lacks real-time competitor analysis.

Only with Ahrefs

Move beyond broad keyword intent categories to uncover precise SERP content types and traffic distribution.

Compare SERPs side by side to identify intent changes over time, whether for the same keyword or different ones.

SEO

Access stronger backlink data and uncover valuable link opportunities more efficiently—without relying on unnecessary toxicity metrics.

A large percentage of SEO professionals prefer DR as their primary SEO metric.

Backlinks Report

Highlight the links that truly matter and filter out irrelevant ones.

Ahrefs’ Best Links filter allows you to customize the types of backlinks displayed across reports and charts.

Semrush’s equivalent filter only displays dofollow links.

Only with Ahrefs

Monitor backlink spikes in real time as they occur.

Find leading authors for outreach and guest posting opportunities.

Unlike Semrush, Ahrefs does not assign toxic link scores, as most harmful links are ignored by Google. However, spam links can still be filtered when needed.

Technical SEO

Identify technical problems more efficiently with comprehensive diagnostics—not limited crawls.

Site Audit

Access full page-level details within a single panel, eliminating the need to switch between reports.

Page Explorer provides a complete diagnostic overview and allows instant page recrawls to confirm whether updates were successful.

Semrush offers less detailed data, requiring navigation across multiple reports and waiting for the next crawl cycle.

Internal Link Opportunities recommends which pages should link together to improve rankings.
