Backlinks remain one of the most critical ranking factors in SEO, yet analyzing them effectively requires powerful tools. Moz’s Link Explorer has been a cornerstone of backlink analysis for over a decade, offering marketers and SEO professionals a window into the link profiles that drive organic rankings. But in a landscape crowded with alternatives like Ahrefs, SEMrush, and Majestic, is Moz’s Link Explorer still worth your attention?
In this comprehensive guide, we’ll break down everything you need to know about Moz’s Link Explorer — from its core features and metrics to practical use cases, pricing considerations, and how it stacks up against the competition. Whether you’re a seasoned SEO professional or a small business owner exploring backlink tools for the first time, this guide will help you decide if Link Explorer belongs in your toolkit.
What Is Moz’s Link Explorer?

Moz’s Link Explorer is a web-based backlink analysis tool that allows users to research the link profile of any website or URL. It replaced the legacy Open Site Explorer in 2018 and features a significantly larger link index, faster crawling, and more granular data. Link Explorer is part of the broader Moz Pro suite but also offers limited free access for basic queries.
At its core, Link Explorer helps you answer critical SEO questions:
- How many backlinks does a domain or page have?
- Which domains are linking to your competitors but not to you?
- What is the authority of the sites linking to any URL?
- Are there spammy or toxic links pointing to your site?
- Which pages on your site attract the most links?
Key Metrics in Moz’s Link Explorer
Understanding the proprietary metrics Moz uses is essential before diving into the tool. Here’s a breakdown of the metrics you’ll encounter:
Domain Authority (DA)
Domain Authority is Moz’s most well-known metric — a 1-100 score predicting how well a website will rank in search engine results. DA is calculated using multiple factors, including linking root domains, total number of links, and MozRank. While not a Google ranking factor, DA is widely used across the SEO industry as a comparative metric for evaluating the relative strength of different domains.
Important note: DA is best used as a comparative metric (comparing your site against competitors), not an absolute one. A DA of 40 means different things in different niches — what matters is how your DA compares to the sites you’re trying to outrank.
Page Authority (PA)
Page Authority works like DA but at the individual page level. It predicts how well a specific page will rank, considering factors like the page’s own backlink profile and internal link equity. PA is especially useful when analyzing specific ranking pages or evaluating potential link acquisition targets.
Spam Score
Moz’s Spam Score uses a machine learning model trained on sites that have been penalized or banned by Google. The score ranges from 1% to 99%, with higher percentages indicating greater risk. This metric is invaluable for link audits — helping you identify potentially harmful backlinks that could trigger manual actions or algorithmic penalties.
Linking Domains
The linking domains metric shows the number of unique root domains that link to a target URL or domain. This is arguably more important than total backlink count, since Google values diversity of linking sources. A site with 100 backlinks from 80 different domains is generally stronger than one with 500 backlinks from 10 domains.
How to Use Moz’s Link Explorer: Step-by-Step
Step 1: Enter Your Target URL
Navigate to Link Explorer (accessible at moz.com/link-explorer or within your Moz Pro dashboard) and enter any URL, subdomain, or root domain you want to analyze. You can toggle between analyzing a specific page, a subdomain, or the entire root domain.
Step 2: Review the Overview Dashboard
The overview dashboard immediately displays DA, linking domains, total inbound links, and ranking keywords. This gives you a quick snapshot of the target’s link profile strength. Pay particular attention to the linking domains trend — a steady upward trend indicates healthy, ongoing link acquisition.
Step 3: Explore Inbound Links
The Inbound Links tab reveals every backlink Moz has discovered pointing to your target. You can filter by:
- Link type — Follow vs. nofollow vs. redirect
- Source DA — Filter to see only links from high-authority sources
- Anchor text — Identify anchor text distribution patterns
- New vs. lost — Track recently acquired or lost links
- Spam Score — Flag potentially toxic links
Step 4: Analyze Linking Domains
The Linking Domains tab provides a deduplicated view of all unique domains linking to your target. This is where you can identify your most valuable link sources and spot patterns in your backlink profile. Sort by DA to see your highest-authority linkers, or sort by Spam Score to identify potentially harmful relationships.
Step 5: Discover Competitor Links
One of Link Explorer’s most powerful use cases is competitor backlink analysis. Enter a competitor’s domain to see who links to them — then identify link opportunities they’ve captured that you haven’t. Cross-reference multiple competitors to find sites that link to several rivals but not to you, as these represent high-probability link acquisition targets.
Step 6: Audit Your Own Link Profile
For your own domains, use Link Explorer to conduct regular link audits. Focus on:
- Identifying and disavowing high Spam Score links
- Monitoring anchor text distribution for over-optimization signals
- Tracking new and lost links to understand your link velocity
- Identifying your most-linked pages (and strengthening internal links to important pages that lack external links)
Moz’s Link Explorer vs. Ahrefs
The most common comparison in backlink analysis is Moz Link Explorer vs. Ahrefs Site Explorer. Here’s how they stack up:
| Feature | Moz Link Explorer | Ahrefs Site Explorer |
|---|---|---|
| Link Index Size | 44 trillion+ links | 35 trillion+ links |
| Authority Metric | Domain Authority (DA) | Domain Rating (DR) |
| Spam Detection | Spam Score (1-99%) | No dedicated spam metric |
| Crawl Freshness | Daily updates | 15-minute crawl cycles |
| Free Access | 10 queries/month (free) | Free Webmaster Tools (limited) |
| Starting Price | $99/month (Moz Pro) | $129/month (Lite) |
| Best For | Spam analysis, DA tracking | Raw backlink data depth |
Both tools have legitimate strengths. Moz’s advantage lies in its Spam Score metric and the industry-wide adoption of Domain Authority as a standard benchmark. Ahrefs excels in crawl freshness and raw data volume, making it preferred for real-time link monitoring and detailed competitive analysis. If you’re looking for affordable access to Ahrefs’ premium features, consider an Ahrefs group buy option for significant savings.
Moz’s Link Explorer vs. SEMrush
SEMrush’s Backlink Analytics module offers similar functionality to Link Explorer, with its own authority metric (Authority Score). SEMrush’s key advantage is integration — backlink data lives alongside keyword research, position tracking, site auditing, and advertising intelligence in a single platform. Moz’s advantage over SEMrush in backlink analysis is the more established Domain Authority metric and the superior Spam Score analysis.

Moz’s Link Explorer vs. Majestic
Majestic is the most specialized backlink tool, focused exclusively on link intelligence. Its proprietary metrics — Trust Flow and Citation Flow — provide a different perspective on link quality than DA/PA. Majestic’s historic index is unmatched for analyzing long-term link trends, while Moz’s Link Explorer offers a broader SEO toolkit as part of Moz Pro. For budget-conscious users, exploring Majestic group buy options can provide premium access at a fraction of the cost.

- DA and PA scores

Practical Use Cases for Moz’s Link Explorer
1. Link Building Prospecting
Use Link Explorer to analyze competitors’ backlink profiles and identify high-value linking domains. Focus on sites with DA 30+ that link to multiple competitors — these represent realistic, high-impact link opportunities. Export the data, qualify each prospect, and build targeted outreach campaigns around your findings.
2. Link Audit and Disavow
Sort your backlinks by Spam Score to identify potentially harmful links. Sites with Spam Scores above 60% warrant investigation — check them manually to determine if they’re genuinely spammy. If so, add them to your Google disavow file to protect your site from potential penalties.
3. Monitoring Link Velocity
Track the rate at which you’re acquiring (and losing) backlinks over time. Sudden spikes in link acquisition could indicate negative SEO attacks, while a declining trend might signal content decay or technical issues. Link Explorer’s timeline views make this monitoring straightforward.
4. Content Strategy Validation
Identify which types of content attract the most backlinks across your site and your competitors’ sites. If original research, infographics, or comparison posts consistently earn more links, you know where to focus your content investment. This data-driven approach eliminates guesswork from content planning.
5. Due Diligence for Domain Purchases
Before acquiring a domain (for a new project or redirect strategy), use Link Explorer to evaluate its backlink profile. Check DA, linking domains, anchor text distribution, and Spam Score to ensure you’re not inheriting a penalized or spammy domain.
Tips for Getting the Most from Moz’s Link Explorer
- Track DA over time — Don’t obsess over a single DA reading. Track your DA monthly to identify trends. A steady upward trajectory is more meaningful than any individual score.
- Focus on linking domains, not total links — Domain diversity matters more than raw link count. A link from 10 new domains is worth more than 100 links from a domain you already have.
- Use Spam Score proactively — Don’t wait for a manual action. Quarterly Spam Score audits help you catch problematic links before they accumulate enough to cause ranking issues.
- Compare root domain vs. exact URL — Analyzing at the root domain level shows overall authority, while URL-level analysis reveals which specific pages carry the most link equity.
- Export and combine data — Link Explorer data becomes more powerful when combined with data from other tools. Export CSV files and merge with Ahrefs or SEMrush data for a more complete backlink picture.
Limitations of Moz’s Link Explorer
No tool is perfect, and Link Explorer has some notable limitations:
- Crawl freshness — While Moz updates its index daily, Ahrefs’ 15-minute crawl cycles catch new links significantly faster. For time-sensitive link monitoring, this delay can be meaningful.
- No link intersect tool — Ahrefs’ Link Intersect feature (find sites linking to competitors A, B, and C but not to you) is extremely valuable for link prospecting and is not available in Moz’s interface natively.
- Limited historical data — Majestic’s historic index provides deeper historical link data than Moz for long-term trend analysis.
- DA fluctuations — Domain Authority can fluctuate without changes to your actual link profile due to index updates and algorithm changes, which can confuse users who rely on it as a primary metric.
Moz’s Link Explorer FAQs
Is Domain Authority a Google ranking factor?
No. Domain Authority is a Moz metric, not used by Google. However, DA correlates well with ranking performance because it’s calculated from signals that Google does use (backlinks, linking domains). Think of DA as a useful approximation, not an official ranking signal.
How often is Moz’s link index updated?
Moz updates its link index daily, with periodic larger recrawls. The index contains 44 trillion links, making it one of the largest backlink databases available.
Can I use Moz’s Link Explorer for free?
Yes — Moz offers 10 free queries per month without an account. For more extensive use, a Moz Pro subscription is required, or you can explore group buy SEO tools for affordable access to premium plans.
What’s a good Domain Authority score?
DA is relative to your niche. A DA of 30 might be excellent for a new blog but low for an established media site. Focus on exceeding the DA of your direct SERP competitors rather than targeting an arbitrary number.
Is Moz’s Spam Score reliable?
Moz’s Spam Score uses a machine learning model trained on penalized sites, making it reasonably reliable. However, no spam detection system is perfect — always manually review flagged links before disavowing them. False positives are possible, especially with foreign-language or niche sites.
