What Is Ahrefs and What Does It Do?
Ahrefs is a professional SEO software suite used by SEO practitioners, digital marketers, and website owners to research keywords, analyze backlinks, audit websites, and spy on competitor strategies. Its core strength is its backlink index — one of the largest and most frequently updated in the industry — and its keyword data from clickstream data covering billions of search queries.
Ahrefs is not free (plans start at $99/month), but it offers a free Ahrefs Webmaster Tools account that gives partial access to site audit and backlink data for your own verified website. For serious SEO work, the paid tier pays for itself many times over in time saved and opportunities uncovered.
Ahrefs' Core Tools: Overview
| Tool | Primary Use | Most Useful For |
|---|---|---|
| Site Explorer | Analyze any website's organic traffic, backlinks, and top pages | Competitor research, backlink analysis |
| Keywords Explorer | Research keyword difficulty, volume, and SERP data | Keyword research, content planning |
| Site Audit | Technical SEO crawl to find issues on your site | Technical SEO audits |
| Content Explorer | Find top-performing content by topic across the web | Content ideas, link building prospects |
| Rank Tracker | Monitor keyword rankings over time | Tracking SEO progress |
| Link Intersect | Find sites that link to competitors but not to you | Link building outreach lists |
| Alerts | Get notified of new/lost backlinks, keyword mentions | Monitoring brand and backlink changes |
Workflow 1: Keyword Research with Keywords Explorer
Keywords Explorer is where most SEO research begins. Here's the step-by-step process for finding the right keywords to target:
Step 1: Seed Keyword Input
Enter a broad topic related to your business (e.g., "website design," "small business website," "SEO"). Ahrefs will return data for this term and suggest thousands of related keywords.
Step 2: Apply Filters to Find Opportunities
| Filter | Recommended Setting | Why |
|---|---|---|
| Keyword Difficulty (KD) | Under 30 for new sites; under 50 for established sites | Only target keywords you can realistically rank for |
| Volume | Minimum 100 searches/month | Enough traffic to be worthwhile |
| Traffic Potential | Minimum 200 | More accurate than volume — includes ranking for related terms |
| Words | Minimum 3 | Long-tail keywords have lower competition |
Step 3: Evaluate the SERP
For any keyword you're considering targeting, click "SERP" to see the current top 10 results. Look at:
- Domain Rating (DR) of ranking pages — if all top 10 have DR 60+, a new site can't compete yet
- Referring domains of #1 result — how many backlinks would you need to match?
- Content format of top results — are they guides, lists, product pages? Match the format
- Traffic Potential of #1 — this tells you the realistic traffic ceiling for that keyword
Step 4: Export and Prioritize
Export filtered keyword lists to CSV. Prioritize keywords by the ratio of Traffic Potential to Keyword Difficulty — high potential, low difficulty keywords first.
Workflow 2: Competitor Analysis with Site Explorer
Site Explorer lets you see any website's organic traffic, top-ranking pages, and complete backlink profile. Use it to understand what's working for competitors:
Top Pages Report
Site Explorer → enter competitor URL → Organic search → Top pages
This shows which pages drive the most organic traffic to a competitor — revealing their highest-value content. Sort by Traffic to find their top performers and look for content gaps you can fill.
Organic Keywords Report
Site Explorer → Organic search → Organic keywords
See every keyword a competitor ranks for, along with position, estimated traffic, and KD. Filter for keywords where they rank in positions 1–10 and your site doesn't rank at all — these are your content gap opportunities.
Backlinks Report
Site Explorer → Backlinks → Referring domains
See every website linking to a competitor. This is your link building prospect list — sites that link to competitors in your niche are likely willing to link to better content on the same topic.
Workflow 3: Backlink Analysis for Your Own Site
Enter your own domain in Site Explorer to understand your current backlink profile:
| Ahrefs Report | What to Look For | Action |
|---|---|---|
| Overview → DR/UR trend | Is authority growing or declining? | Benchmark and track over time |
| Referring domains → New vs. Lost | Are you gaining or losing links? | Investigate lost links — reach out to recover |
| Backlinks → Anchors report | What anchor text do your links use? | Check for over-optimization (too many exact-match anchors) |
| Backlinks → DR filter (under 10) | Low-quality links to your site | Consider disavowing truly toxic links |
| Best by links report | Which pages have the most backlinks? | These are your link magnets — create more similar content |
Workflow 4: Content Gap Analysis
The Content Gap tool shows keywords that competitors rank for but your site doesn't — revealing topics you should cover:
- Site Explorer → enter your domain
- Click "Content gap" in the left sidebar
- Enter 2–4 competitor domains in the fields provided
- Click "Show keywords"
- Filter results: KD under 30, minimum volume 100
- Export and add to your content calendar
This workflow is one of the highest-ROI uses of Ahrefs — it tells you precisely which topics are driving competitor traffic that you're missing entirely.
Workflow 5: Link Building with Link Intersect
Link Intersect identifies websites that link to multiple competitors but not to you — the most qualified link prospects available:
- Go to Site Explorer → More → Link Intersect
- Enter 3–5 competitor domains in the target fields
- Enter your own domain in the "But doesn't link to" field
- Click "Show link opportunities"
- Filter by DR (minimum 30) to focus on quality prospects
- Export the list for outreach
Sites linking to multiple competitors in your space have already demonstrated willingness to link to content like yours. Your outreach to these sites is warmer than cold outreach to unrelated websites.
Workflow 6: Site Audit for Technical SEO Issues
Ahrefs' Site Audit crawls your website and categorizes technical issues by severity:
| Audit Category | What Ahrefs Checks | Priority |
|---|---|---|
| Errors (red) | Broken links, missing title tags, HTTP pages, missing H1, duplicate pages | Fix immediately |
| Warnings (orange) | Low word count, missing meta descriptions, slow pages, redirect chains | Fix soon |
| Notices (blue) | Nofollow links, minor issues, informational flags | Review and consider |
Schedule Site Audit to crawl weekly or monthly to catch new issues as they arise. The Health Score (0–100) gives a site-wide quality indicator that improves as issues are resolved.
Ahrefs Metrics Explained: The Key Numbers
| Metric | What It Measures | How to Use It |
|---|---|---|
| DR (Domain Rating) | Strength of a domain's backlink profile (0–100) | Assess competitor authority; benchmark your own growth |
| UR (URL Rating) | Strength of an individual page's backlinks (0–100) | Evaluate ranking potential of specific pages |
| KD (Keyword Difficulty) | How hard it is to rank in top 10 (0–100) | Filter for achievable keyword targets |
| Volume | Estimated monthly searches for a keyword | Gauge demand; don't use as sole metric |
| Traffic Potential | Estimated monthly clicks if you rank #1 (includes ranking for related terms) | More accurate than volume for traffic estimation |
| Referring Domains | Number of unique websites linking to a URL or domain | More important than total backlinks |
Free Ahrefs Tools Worth Using
Even without a paid account, Ahrefs offers several free tools:
- Ahrefs Webmaster Tools: Free access to Site Audit and partial backlink data for verified sites you own — valuable for technical audits and monitoring your own backlink profile

The Bottom Line
Ahrefs is most valuable when used systematically rather than sporadically — the highest-ROI workflows are: content gap analysis to find competitor keywords you're missing, Keywords Explorer filtered for low-KD opportunities with significant Traffic Potential, Link Intersect to build targeted outreach lists, and Site Audit on a regular schedule to catch technical issues early. The combination of these four workflows covers the core of what most business-focused SEO programs need from a professional tool. Start with the free Ahrefs Webmaster Tools if budget is a constraint, and upgrade to paid access when the keyword research and competitor intelligence become central to your growth strategy.
