How Moz Link Explorer Works

Moz Link Explorer is the tool behind the Moz Backlink Checker. You type a URL into the search box and it returns a list of linking domains and pages. The tool also shows metrics like Domain Authority and Page Authority for each link.

To use it, you need a free Moz account. After email verification, you get 10 queries per month. Each query can be for a domain, subdomain, or exact page. The results update as Moz’s crawler discovers new links.

Moz’s index is not the entire web. It is a third-party estimate. Google has its own index, which is larger and not publicly accessible. So the backlinks you see in Moz are a sample, not a complete list.

For example, entering your own domain might show 50 linking root domains and 200 total links. Clicking a domain reveals the specific linking pages, helping you identify which of your pages attract the most links. The tool also shows the date when the link was first seen, giving you an idea of link age.

What Data Moz Backlink Checker Provides

When you run a query, Moz shows several columns of data. The main ones are Linking Root Domains, Total Links, and Domain Authority. You can also see the anchor text used in each link and whether the link is followed or nofollowed.

The tool groups links by domain. You can expand each domain to see individual pages. This helps you understand the Backlink Profile of a site. For example, you might see that most links come from a few high-authority domains or many low-quality ones.

Moz also provides a spam score for each linking domain. This score estimates how likely a domain is to be penalised by Google. It is based on patterns seen in penalised sites. Use it as a warning, not a definitive judgement.

The anchor text column shows the exact text used. For instance, many 'click here' links may indicate low quality. Spam score above 5% warrants investigation; you can click a domain to see its own backlinks. You can also see the link type (text, image, or nofollow) in the detailed view.

  • Linking Root Domains: number of unique domains linking to your target.
  • Total Links: count of all backlinks, including multiple from the same domain.
  • Domain Authority: Moz’s prediction of ranking strength (0–100).
  • Page Authority: similar prediction for individual pages.
  • Spam Score: estimate of penalisation risk (0–17%).

Free vs Paid Access in Moz Link Explorer

The free version of Moz Backlink Checker gives you 10 queries per month. Each query returns up to 10,000 backlinks. You can see the top linking domains and some metrics. For deeper analysis, you need a paid subscription.

Paid plans start at $99 per month. They include unlimited queries, historical data, and CSV exports. You also get access to Moz’s API for automated checks. The paid version shows more backlinks per query and allows filtering by date or link type.

If you only need a quick check, the free version is enough. For ongoing how backlink monitoring works, you may want the paid plan. Many SEOs start with the free tier and upgrade when they need more data.

For example, if you are auditing a new client’s site, you might need to check dozens of URLs. The free tier would not suffice. Paid plans also allow you to track changes over time, which is useful for monitoring link building campaigns. The paid version includes a link intersect tool to compare backlink profiles of multiple domains.

Using Moz Backlink Checker for Competitor Research

You can enter a competitor’s domain to see their backlinks. This reveals where they get links from. You might find guest post opportunities, directory listings, or industry publications that also link to you.

Moz’s blog recommends sorting by Domain Authority to find high-value prospects. Focus on domains with DA above 30. Then check if those sites accept guest posts or have resource pages. This is a common what ahrefs backlink checker means strategy as well.

Compare your backlink profile with competitors using the ‘Compare’ feature in Link Explorer. It shows overlapping and unique linking domains. This helps you identify gaps in your own link building. Remember that what moz means metrics are estimates, so treat them as signals, not facts.

For example, if a competitor has links from five industry blogs you do not, you can target those blogs. Look at the anchor text they use and the page context. Replicate their approach but with your own content. Also check if any of their links come from broken pages you could replace.

Limitations of Moz Backlink Checker

Moz’s index is smaller than Ahrefs or Semrush. Some studies show Moz finds fewer backlinks for the same URL. This means you might miss important links. Always cross-check with other tools or Google Search Console.

Domain Authority is not a Google ranking factor. Google has said this repeatedly. Treating DA as a direct ranking signal can lead to poor decisions. For example, you might chase a high-DA link that is irrelevant to your audience.

The free version has a low query limit. If you need to check many URLs, you will hit the cap quickly. Also, the data is not real-time. Moz updates its index every few weeks, so recent links may not appear.

Finally, the tool does not show the full context of a link. You cannot see the surrounding page content or whether the link is in a sidebar. For that, you need to visit the page yourself.

Moz Backlink Checker vs Other Tools

Moz is one of several backlink checkers. Others include semrush backlink checker and Ahrefs. Each has its own index and scoring system. Moz’s index is generally smaller but its metrics are widely used.

Semrush offers a larger index and more frequent updates. Ahrefs is known for its huge index and detailed link analysis. Majestic focuses on historical data and citation flow. No single tool shows every backlink.

Choose Moz if you already use its ecosystem or need a quick, free check. For serious link building, many SEOs use multiple tools. You can also use how seo checker works tools that combine data from several sources.

For instance, if you find a link in Moz but not in Ahrefs, it might be a new link not yet crawled by Ahrefs. Cross-referencing helps you decide which links to pursue. Each tool has strengths, so using two or three gives a fuller picture.

  • Moz: smaller index, free tier, DA metric.
  • Ahrefs: largest index, paid only, many features.
  • Semrush: large index, paid, integrates with other SEO tools.
  • Majestic: historical data, citation flow, trust flow.

Best Practices When Using Moz Backlink Checker

Start with your own domain. Check for Bad Backlink patterns like spammy directories or irrelevant sites. Use the spam score to identify risky links. Disavow them if necessary.

When researching competitors, look for link types. Are they getting editorial links, guest posts, or directory submissions? Replicate the strategies that work. But do not copy low-quality tactics.

Use the free queries wisely. Plan your research before running a query. Export data if you have a paid plan. For ongoing monitoring, set up alerts in Moz or use a dedicated backlinks checker tool.

For example, if you see a competitor has a link from a high-DA blog, visit that blog to see if they accept guest contributions. Check the anchor text they used and write a better piece. Also look at the linking page’s topic to ensure relevance. This targeted approach yields better results than mass outreach.

Common mistakes

  • Treating Domain Authority as a Google ranking factor. You may prioritise high-DA links that are irrelevant, wasting time and resources.
  • Assuming Moz shows every backlink on the web. You miss important links that are in other indexes or not crawled yet.
  • Using Link Explorer only for link quantity and ignoring quality. You build many low-quality links that could harm your site’s reputation.
  • Relying on Moz alone for competitor research. You get an incomplete picture and may overlook opportunities visible in other tools.
