Ahrefs Site Explorer gives you the most comprehensive backlink database available, with over 35 trillion links and data refreshed every 15 minutes. You'll analyze your site's link profile, audit for toxic links, spy on competitors' best backlinks, and find high-value link building opportunities that actually move the needle.
This process takes serious time investment but delivers actionable insights that separate amateur SEOs from professionals. You need an active Ahrefs subscription (Lite minimum for decent data, Standard or higher for full functionality) and basic familiarity with link metrics like Domain Rating and URL Rating.
What You'll Need
An active Ahrefs account with Site Explorer access, your domain verified in Ahrefs Webmaster Tools (recommended but not required), and competitor domains you want to analyze. You'll also want a spreadsheet tool for organizing findings and prioritizing opportunities.
Step 1: Set Up Your Domain Analysis
Time: 5 minutes | Tool: Ahrefs Site Explorer Enter your domain in Site Explorer and select "Exact domain" from the dropdown to focus only on your main domain, not subdomains. Click the Overview tab to see your Domain Rating, total backlinks, and referring domains at a glance. The key metric here is referring domains — that's unique websites linking to you, which matters more than total backlinks. Pay attention to the Ahrefs Rank, which shows how your domain ranks globally by link strength. Anything under 100,000 is solid for most sites. The overview chart shows your backlink growth over time — you want steady upward trend, not spikes followed by drops that suggest link schemes. Check the top-level metrics but don't get stuck here. The real insights come from diving deeper into specific sections.
Step 2: Audit Your Current Backlink Profile
Time: 15 minutes | Tool: Ahrefs Site Explorer Click the "Backlinks" tab to see all links pointing to your domain. Set the filter to "One link per domain" to avoid spam from sites that link hundreds of times. Sort by "DR" (Domain Rating) descending to see your highest-authority links first. Export the top 1,000 backlinks and scan for obvious problems: links from foreign gambling sites, adult content, or domains with suspicious names like "best-seo-links-2023.com." Red flags include massive DR drops in your linking domains, identical anchor text patterns, or clusters of links from the same IP range. Use the "Lost" filter to see recently lost backlinks. Natural link loss happens, but sudden drops of high-DR links need investigation. You might need to reach out to webmasters about broken pages or site migrations.
Step 3: Identify Your Link Building Assets
Time: 10 minutes | Tool: Ahrefs Site Explorer Switch to the "Best by links" report under "Pages" to see which of your pages attract the most backlinks. These are your link magnets — content that naturally earns links. Study what makes them successful: comprehensive data, original research, useful tools, or controversial takes. Look for patterns in your most-linked content. If your "Ultimate Guide to X" posts consistently earn links while product pages don't, that tells you something about content-market fit. The "Best by links" report also reveals pages with declining link counts, which might need updates or promotion. Note pages with high link counts but low organic traffic — these might be great internal linking sources to boost other pages.
Step 4: Analyze Competitor Backlink Strategies
Time: 15 minutes | Tool: Ahrefs Site Explorer Enter your main competitor's domain in Site Explorer. Go straight to the "Best by links" report to see their most successful content from a link building perspective. This reveals what topics and formats work in your industry. Click individual competitor pages to see their full backlink profiles. Look for patterns: Do they get links from industry publications? Resource pages? Are their links from guest posts, mentions, or organic editorial coverage? The "Anchors" tab shows what anchor text patterns work for them. Use the "Link intersect" tool (under "More" in the left sidebar) to find sites linking to multiple competitors but not you. These are warm prospects since they already link to your industry.
Step 5: Find Broken Link Opportunities
Time: 8 minutes | Tool: Ahrefs Site Explorer Go to Site Explorer and enter a competitor domain, then click "Backlinks" and filter by HTTP response code "404." These are broken links pointing to their content — opportunities for link reclamation. Focus on broken links from high-DR domains in your industry. Export the list and manually check each broken page using the Wayback Machine to see what content used to be there. If you have similar or better content, you can reach out to the linking site suggesting your page as a replacement. This works especially well for resource pages, statistics collections, and industry tool lists where your content genuinely fits.
Step 6: Discover Link Building Prospects
Time: 10 minutes | Tool: Ahrefs Content Explorer Switch to Content Explorer and search for content topics in your niche published in the last year with at least 50 referring domains. These are articles that recently earned significant links — study their approaches and create better versions. Use the "One article per domain" filter to avoid seeing multiple posts from the same site. Export the results and analyze the most successful pieces: What angles did they take? What data did they present? What made sites want to link? Look for content gaps where you could create definitive resources. If competing articles only cover part of a topic, your comprehensive coverage could become the new go-to resource.
Step 7: Monitor and Track Progress
Time: 2 minutes | Tool: Ahrefs Alerts Set up Ahrefs Alerts for your domain to get weekly reports on new backlinks, lost links, and brand mentions. Go to "Alerts" in the main navigation and create a "Backlinks" alert for your domain. Configure the alert to show new links with DR 30+ to focus on quality over quantity. Also set up alerts for your brand name and key executives to catch unlinked mentions that could become link opportunities. Create competitor alerts to monitor when they gain or lose significant backlinks — sometimes you can swoop in to claim lost opportunities or analyze their new link building campaigns.
Pro Tips
Ahrefs' "Link intersect" tool beats manual competitive analysis every time. Input 3-5 competitors to find sites linking to multiple competitors — these publishers already cover your industry and might be interested in your content too. The "Referring domains" report's "New" filter shows domains that just started linking to competitors, indicating active link builders or recent content campaigns worth investigating.
Common Pitfalls
Don't chase Domain Rating as your primary metric — it's Ahrefs' proprietary score, not what Google uses. Focus on relevance and traffic potential instead. Also avoid bulk disavowing links without manual review. Ahrefs flags many harmless links as "toxic," and aggressive disavowing can hurt more than help. Google ignores most spam links automatically.
Expected Results
After completing this analysis, you'll have a prioritized list of 20-50 high-potential link prospects, identified 5-10 pieces of linkable content to create, and established monitoring systems to track competitor moves. Most importantly, you'll understand what link building strategies actually work in your specific industry rather than following generic advice.
