When I first started out, figuring out how to improve a website’s ranking felt like trying to solve a puzzle with half the pieces missing. Then I stumbled upon Semrush backlinks analysis, and honestly, it felt like someone handed me the instruction manual for the internet. If you’re looking to really understand and boost your site’s SEO, mastering backlink analysis with a powerful tool like Semrush isn’t just helpful. it’s absolutely essential.

Think of backlinks as votes of confidence from other websites. The more high-quality, relevant votes your site gets, the more trustworthy and authoritative search engines like Google see you. This isn’t just about getting any links. it’s about getting the right links, and that’s where Semrush shines. It helps you dissect your own site’s link profile, peek behind the curtain at what your competitors are doing, and uncover tons of opportunities to build strong, healthy links that genuinely move the needle for your rankings. Without this kind of insight, you’re essentially guessing, and in the competitive world of SEO, guessing just won’t cut it. Semrush is a powerhouse, giving you the data and tools to make informed decisions, improve your online presence, and ultimately, drive more traffic to your business.

Before we jump into the tools, let’s quickly chat about what backlinks are and why they’re such a big deal. Simply put, a backlink is a link from one website to another. When another site mentions your content and links back to it, that’s a backlink for your site. But these aren’t just simple hyperlinks. they’re critical signals to search engines.

Google, for example, treats backlinks as a strong indicator of a page’s quality, relevance, and authority. Imagine if a highly respected expert in your field referenced your work in their own publication – that instantly boosts your credibility, right? Backlinks work in a similar way online. The more authoritative and relevant the linking site is, the more “link equity” or “authority” that link passes to your site.

This is all thanks to algorithms like Google’s original PageRank, which measures page authority. A page with high PageRank passes more authority to the pages it links to. So, if you’re getting links from well-established, trustworthy sites, it tells Google that your content is valuable and deserves to rank higher in search results. In fact, many SEO experts consider backlinks one of the top three ranking factors.

But here’s the catch: not all backlinks are created equal. You want high-quality backlinks from reputable, authoritative domains. Low-quality, spammy links can actually hurt your site’s reputation and rankings, potentially even leading to penalties. That’s why analyzing and managing your backlink profile is so important.

Diving into Semrush Backlink Analysis: Your Step-by-Step Guide

Alright, let’s get into the nitty-gritty of how you actually use Semrush to analyze backlinks. Whether you’re scrutinizing your own site or trying to figure out what your rivals are up to, the process often starts in a similar place.

Unleashing Your Online Potential: The Game-Changing Advantages of Semrush

Step 1: Getting Started with Backlink Analytics

To really get going, you’ll usually start with the Backlink Analytics tool.

Log In and Navigate: Head over to your Semrush dashboard. On the left-hand sidebar, you’ll typically find the “Link Building” section, and under that, “Backlink Analytics.”
Enter Your Domain or a Competitor’s: In the search bar, type in the domain you want to analyze. This could be your own website, a specific page, or a competitor’s domain. Then hit “Analyze.”

Once you hit that button, Semrush pulls up a “Domain Overview” that gives you a quick snapshot of the site’s backlink situation. This includes things like:

Total Backlinks: The sheer number of links pointing to the domain.
Referring Domains: This is super important – it’s the total number of unique websites linking to the domain. A higher ratio of referring domains to total backlinks often indicates a more natural and healthy link profile.
Authority Score AS: This is Semrush’s proprietary metric, graded on a scale of 1 to 100. It’s basically a measure of a domain’s overall strength and trustworthiness, taking into account link quality, quantity, organic traffic, and how natural its backlink profile looks. The higher the score, the more influential the site is.
New & Lost Backlinks: You’ll see trends here, like how many new links the site has gained and how many it’s lost over specific periods. This helps you monitor changes in your backlink profile or a competitor’s.

These overview metrics are your starting point, giving you an immediate sense of the domain’s backlink health and how it stacks up.

Step 2: Deep Dive into Your Backlink Profile or a Competitor’s

After the overview, you’ll want to explore the specific tabs within Backlink Analytics for more detail. Navigating BrightEdge: The Real Talk from Reddit and Beyond

The “Backlinks” Tab

This tab gives you a comprehensive list of every single backlink pointing to the analyzed domain. It’s a goldmine of information, showing you:

Source Page URL: The exact page where the backlink originates.
Target URL: The specific page on your site or the competitor’s that the link points to.
Anchor Text: This is the clickable text of the link. Anchor text analysis is crucial because it tells you what keywords people are using when linking to your content. A diverse and relevant set of anchor texts looks natural to Google. Watch out for over-optimized or spammy anchor texts, as these can be a red flag.
Link Attributes Dofollow/Nofollow: This tells you if the link passes “link equity” dofollow or if search engines are instructed not to count it towards ranking nofollow. You generally want a good balance, but dofollow links are typically more valuable for SEO.
Authority Score of the Referring Page: Not just the domain, but the specific page linking to you.

You can use a ton of filters here – by link type text, image, platform type blog, forum, TLD .com, .org, and more. This helps you segment your data and find exactly what you’re looking for.

The “Referring Domains” Tab

While the “Backlinks” tab lists individual links, the “Referring Domains” tab focuses on the unique websites that are linking to you. This is important because getting many links from a few domains is less impactful than getting links from many different, high-authority domains.

Here, you can see:

A list of all unique referring domains.
Their Authority Scores.
The total number of backlinks they send to your site.
Their estimated monthly organic traffic gives you a sense of their overall power.

You can track trends in referring domains over time to see if your link growth is consistent or stagnant compared to your rivals. Is semrush reliable

The “Indexed Pages” Tab

Want to know which of your pages or your competitor’s are attracting the most links? The “Indexed Pages” tab shows you exactly that. Sorting this by “Domains” can highlight your most successful content in terms of link acquisition. This insight is fantastic for shaping your content strategy – if certain types of content like ultimate guides, original research, or visual assets are consistently earning links, you know what to focus on.

Step 3: Conducting a Backlink Audit with Semrush

This is where you put on your detective hat and look for anything that might be harming your site. Toxic backlinks are those low-quality, spammy links from questionable sources that can actively damage your SEO and potentially lead to Google penalties. The Backlink Audit Tool in Semrush is specifically designed to help you find and deal with these.

Here’s how it typically works:

Set Up a Project: For a full audit, you’ll want to create a project for your domain within Semrush. This lets the tool continuously track your profile.
Start the Audit: Navigate to the “Backlink Audit” tool under the “Link Building” section. Enter your domain and configure the audit settings. Semrush will then crawl and analyze your backlink profile.
Review the Toxicity Score: Semrush assigns a Toxic Score to each backlink, usually on a scale of 0 to 100 higher means more harmful. It uses over 45 different markers to identify potentially toxic links, looking for things like spammy domains, irrelevant content, or suspicious anchor text.
Identify and Disavow Toxic Links:
- The tool will categorize links into “toxic,” “potentially toxic,” and “non-toxic.” Focus on those with high toxicity scores e.g., 60 or more.
- Once you’ve identified these harmful links, you have a couple of options. You can try to contact the website owners and politely ask them to remove the link.
- If that doesn’t work which is often the case, you can use Semrush to compile a disavow file. This is a list of URLs or domains that you submit to Google Search Console, essentially telling Google, “Hey, don’t count these links against me.” Semrush makes this process pretty straightforward, allowing you to build and export this file.
Ongoing Monitoring: The Backlink Audit tool also helps you monitor for new or lost backlinks over time. This proactive approach ensures you catch new toxic links quickly and can react to changes in your profile.

Regularly auditing your backlinks isn’t just about avoiding penalties. it’s about maintaining a healthy, strong backlink profile that supports your long-term SEO success. Is Semrush Worth It? (A Deep Dive for Your Business)

Step 4: Uncovering Opportunities with Backlink Gap Analysis

This is one of my favorite features because it’s like having a cheat sheet for link building! The Backlink Gap tool helps you identify websites that are linking to your competitors but not to you. It’s a fantastic way to uncover untapped link-building opportunities.

Here’s how to use it:

Access the Tool: In Semrush, find the “Backlink Gap” tool, usually under “Link Building” or “Competitive Research.”
Enter Domains: You can add your domain and up to four or sometimes five competitor domains.
Analyze and Discover: Semrush will then compare the backlink profiles of all entered domains. The results will highlight “Best” link-building prospects – these are typically domains that link to all of your analyzed competitors but are not currently linking to your site.
Prioritize Outreach: This gives you a targeted list of websites to reach out to. Why? Because they’ve already shown a willingness to link to content similar to yours since they link to your competitors. You can investigate why they link to your rivals e.g., a specific piece of content, an interview, a resource page and then strategize how to get your own link.

This tool is incredibly powerful for devising effective link-building strategies, especially for outreach campaigns where you propose valuable content or partnerships.

Finding Blog Topics That Actually Matter

Step 5: Leveraging the Link Building Tool

Once you’ve identified potential link prospects, the Link Building Tool in Semrush helps you manage your outreach efforts.

Set Up a Project: This tool works within a project, where you define your target keywords and competitors.
Prospect Generation: Based on your inputs and Semrush’s vast database, the tool generates a list of potential linking opportunities. It assesses the domain authority and relevance of these prospects.
Manage Outreach: You can then track your outreach process directly within the tool – from initial contact to securing the link. It streamlines your workflow, making link building more efficient.

This tool essentially helps you operationalize your link-building strategy, turning insights into actual, secured backlinks.

Key Metrics and Insights to Watch For

While using these tools, you’ll encounter several important metrics. Knowing what they mean helps you make smarter decisions.

Authority Score AS

As mentioned, this is Semrush’s metric for a domain’s overall strength 1-100. A higher AS means a more powerful domain. When analyzing backlinks, pay attention to the AS of the referring domains. Links from high-AS sites pass more value. Semrush Pricing: Your Ultimate Guide to Choosing the Right Plan in 2025

Referring Domains vs. Total Backlinks

Always look at both. A site with 1,000 backlinks from 10 referring domains is usually less powerful than a site with 1,000 backlinks from 500 referring domains. The latter shows a more diverse, natural, and robust link profile.

Link Attributes Dofollow vs. Nofollow

Dofollow links pass “link juice” and positively influence your search rankings.
Nofollow links don’t directly pass link equity but can still drive referral traffic and increase brand visibility. A healthy profile has a mix, but you’ll usually prioritize dofollow links for SEO benefit.

Anchor Text Distribution

Monitor the anchor text that links to your site. It should be natural and diverse, reflecting the content of the linked page. If too many links use the exact same keyword as anchor text, it can look manipulative to Google and potentially lead to penalties. Semrush lets you audit your anchor texts to prevent over-optimization.

Toxicity Score

This is your warning system. Keep an eye on any links flagged with a high toxicity score and take action to either remove them or disavow them through Google Search Console. Regularly reviewing these helps maintain a clean, healthy backlink profile.

New and Lost Backlinks

Monitoring these trends helps you understand the dynamics of your backlink profile. Are you consistently gaining new, high-quality links? Are you losing important links that you might need to try and reclaim? Semrush’s project features can send you alerts for these changes.

Frequently Asked Questions

What exactly is a “toxic backlink” in Semrush?

A “toxic backlink” in Semrush refers to a low-quality or spammy link from a questionable source that could potentially harm your website’s search engine rankings. Semrush’s Backlink Audit tool identifies these links by analyzing over 45 markers, such as the trust score of the linking domain, the relevance of its content, and the presence of suspicious activities like link farms or spammy directories. A high toxicity score typically 60 or more on a scale of 0-100 indicates a greater risk, signaling that you should consider disavowing the link.

How does Semrush calculate the Authority Score?

Semrush’s Authority Score AS is their proprietary metric that evaluates the overall quality and influence of a domain or webpage, on a scale from 1 to 100. It’s calculated based on several factors: the quality and quantity of backlinks pointing to the domain, its estimated monthly organic traffic, and indicators of a natural vs. spammy link profile. Essentially, a higher AS means the domain is more trustworthy and authoritative in the eyes of search engines, and its outgoing links would pass more link equity.

Can I really find new link-building opportunities with Semrush?

Absolutely! Semrush is fantastic for finding new link-building opportunities. The Backlink Gap tool lets you compare your site’s backlink profile with up to five competitors, highlighting domains that link to them but not to you. This gives you a targeted list of prospects already interested in content related to your niche. Additionally, by analyzing the “Indexed Pages” tab within Backlink Analytics for your competitors, you can see which of their content pieces are earning the most links, inspiring you to create similar high-quality, link-worthy content.

What’s the difference between “referring domains” and “total backlinks”?

This is a common question! Total backlinks simply refers to the total number of links pointing to a website, regardless of where they come from. So, if one website links to your site five times, that counts as five total backlinks. Referring domains, on the other hand, count the number of unique websites that are linking to your site. Using the same example, those five links from one website would count as only one referring domain. Having a higher number of referring domains relative to your total backlinks often indicates a more diverse and healthier link profile, which is generally better for SEO.

How often does Semrush update its backlink data?

Semrush is known for having one of the largest and freshest backlink databases in the industry. They constantly update their data, with their web crawler scanning 10 billion URLs every single day. This ensures that when you perform a backlink analysis, you’re looking at the most recent link acquisitions and losses, allowing you to react quickly to changes in your or your competitors’ backlink profile. This fresh data is crucial for an effective and up-to-date SEO strategy. Mastering Technical SEO with Semrush Academy: Your Path to Website Excellence
