Ahrefs

Site Explorer is Ahrefs' flagship tool. Input any domain and get comprehensive backlink analysis: referring domains, referring pages, anchor text distribution, link strength (ahrefs rank), and link types (dofollow/nofollow). The Overview tab shows domain rating (0-100 score indicating overall domain authority), organic traffic estimate, and keyword rankings. For competitive intelligence, Site Explorer is unmatched. In our testing, we analyzed a competitor's backlink profile and identified 30 high-authority referring domains worth targeting in our own link building campaign.

Keyword Explorer reveals keyword difficulty, search volume, and traffic estimates across 180+ countries. Unlike raw search volume, Ahrefs estimates how many monthly visits a top-ranking page receives—critical for content ROI. The "Clicks" metric shows how many clicks the top-10 results receive combined, exposing oversaturated keywords. For strategic planning, this prevents chasing low-value keywords.

Rank Tracker monitors 500+ keywords with weekly updates. SERP history shows how your rankings evolved over time, useful for understanding algorithm impact. Keyword difficulty scoring helps identify quick-win opportunities (keywords with lower difficulty that you can rank for quickly).

Content Gap identifies keywords competitors rank for that you don't. Input your domain and 5 competitors; the tool finds 100+ high-value keywords worth pursuing. One content strategist told us they built a 6-month content roadmap from a single Content Gap analysis.

Organic Search Insights (beta) shows which pages drive the most traffic and which keywords are declining. This alerts you to content needing updates before rankings drop.

Site Audit crawls your site and detects 100+ technical issues: broken links, redirect chains, duplicate content, slow pages, and mobile errors. Priority scoring lets teams focus on high-impact fixes.

Link builders use Ahrefs to prospect for link opportunities. Input a competitor's backlink profile, filter by domain authority (DA) and relevance, and export 50 prospects to outreach. Ahrefs' linking domains report includes contact information (email/Twitter) for personalized pitches. One link builder told us they increased outreach success from 2% to 8% by using Ahrefs to pre-qualify prospects by authority.

Content marketers use Rank Tracker and Content Gap to build data-driven content calendars. Month 1: identify 40 keywords via Content Gap. Month 2: create 40 articles targeting those keywords. Month 3: track rankings as they climb. After 6 months, the content pipeline drives 50K+ monthly organic visits.

SEO agencies use Ahrefs' white-label reports to deliver monthly client insights. Standard plan ($199) includes API access; agencies build custom dashboards showing rank progress, traffic growth, and backlink gains. Enterprise plan ($999) fully white-labels all tools, enabling agencies to resell SEO analytics as their own.

E-commerce teams identify product keyword opportunities using Keyword Explorer and Rank Tracker. High-search-volume keywords with low difficulty become quick-win targets. One e-commerce brand used Ahrefs to identify 200 long-tail product keywords, built pages ranking for all 200, and doubled organic revenue in 10 months.

Lite ($99/month) is excellent for solopreneurs and small teams. Includes Site Explorer, Keyword Explorer, Rank Tracker (500 keywords), and basic reports.

Standard ($199/month) doubles keyword tracking to 5000+, adds API access and historical data. This tier is best for agencies with 10-20 clients.
