What is a Backlink Audit and Why is it Essential?
Before diving into the specific steps, it is crucial to understand the purpose of a backlink audit. It is a foundational SEO task that provides a wealth of strategic insights. A clear understanding of its goals is the first step toward performing one effectively.
A Clear Definition of a Backlink Audit
A backlink audit is the process of systematically evaluating all the external links that point to your website. The goal is to assess the quality, relevance, and overall health of your entire backlink profile. This analysis involves using specialized tools to gather data. It also requires a careful manual review to identify potential issues and opportunities. A complete backlink audit is a cornerstone of technical SEO.
The Dangers of an Unaudited Backlink Profile
An unaudited backlink profile is a major liability. You may have dozens or even thousands of harmful links pointing to your site without your knowledge. These bad links can lead to algorithmic suppression or even a manual penalty from search engines. Ignoring your backlink profile is like ignoring a potential security threat. It is a risk that is not worth taking.
The Primary Goals of a Successful Audit
A successful backlink audit has several key goals. The first is to identify any potentially toxic backlinks that could be harming your site. The second is to understand the overall quality and composition of your link profile. The third is to find opportunities to improve your profile. The ultimate goal is to create a clean, authoritative, and defensible backlink profile.
Step 1: Gather Your Complete Backlink Data
The first step in any credible backlink audit is to gather a complete and comprehensive list of all the links pointing to your site. You cannot analyze what you cannot see. A thorough data collection process is the foundation for the entire audit.
The Importance of a Comprehensive Data Set
To get a true picture of your backlink profile, you need to use data from multiple sources. Relying on a single tool can lead to an incomplete analysis. Different tools have different crawlers and different data indexes. By combining data from several sources, you can create the most comprehensive master list of your backlinks.
Using Google Search Console for a Baseline
Google Search Console is the best place to start. The “Links” report in GSC will give you a list of the links that Google has discovered pointing to your site. This data is free and comes directly from the source. You should export this list as your baseline.
Using Multiple SEO Tools
Next, you should use one or more paid SEO tools to gather more data. Suites like Ahrefs, SEMrush, and Moz have much larger and more frequently updated backlink indexes than Google Search Console. You should export the full backlink profile from at least one of these tools. Using two is even better.
Consolidating All Data into a Master Spreadsheet
Once you have your exports from GSC and your SEO tools, you need to consolidate them into a single master spreadsheet. You can use a spreadsheet program like Google Sheets or Microsoft Excel for this. Combine all the lists and then use a “remove duplicates” function to create one clean, comprehensive list of all your backlinks.
Step 2: Analyze for Link Toxicity
This is the risk assessment phase of the backlink audit. In this step, you will carefully review your master list of links. Your goal is to identify any links that are potentially toxic or harmful. This requires a keen eye and a clear understanding of what makes a link bad.
The Core of the Risk Assessment Process
The core of this step is to manually or semi-automatically review each linking domain. You are looking for the red flags that are associated with low-quality or manipulative link building. Most SEO tools provide a “toxicity” or “spam” score that can help you to prioritize this process. However, a manual review is still essential.
Identifying Obvious Spam and Link Schemes
Look for links that are clearly from spammy sources. This includes links from blog comments with keyword-stuffed usernames. It also includes links from foreign-language websites that have no relevance to your own. These types of links are classic examples of spam and should be flagged as toxic.
How to Spot Links from Private Blog Networks (PBNs)
Private Blog Networks, or PBNs, are a common source of toxic links. These are networks of websites that are created solely for the purpose of building links. Signs of a PBN include a generic theme, low-quality content, and a large number of outbound links to unrelated sites. Links from these networks are very risky.
Finding and Flagging Irrelevant Backlinks
A link from a website that is completely irrelevant to your industry is a major red flag. For example, if you have a website about pet care and you have a link from a casino website, that is an unnatural and potentially harmful link. A healthy backlink profile consists of links from topically relevant sites.
Step 3: Evaluate Anchor Text Distribution
The anchor text of your backlinks is another important signal that search engines analyze. A thorough backlink audit must include a review of your anchor text profile. An unnatural profile can be a sign of manipulative link building.
What is Anchor Text and Why Does it Matter?
Anchor text is the clickable text of a hyperlink. It provides context to both users and search engines about the topic of the linked page. Search engines use anchor text as a signal to understand what a page is about.
The Dangers of Over-Optimized Anchor Text
Over-optimized anchor text is when a large percentage of your backlinks use the exact same, keyword-rich phrase. For example, if 50% of your links have the anchor text “best running shoes,” this is a very unnatural and aggressive signal. It is a common footprint of manipulative link building schemes and can trigger a penalty.
How to Analyze Your Anchor Text Profile
Most SEO tools have a report that shows you your anchor text distribution. It will show you a list of all the anchor texts used in your backlinks and the percentage of each. You should review this list to look for any signs of over-optimization.
The Signs of a Natural vs. a Manipulative Profile
A natural anchor text profile has a great deal of diversity. It will have a high percentage of branded anchors (your brand name). It will also have many generic anchors (like “click here”) and naked URL anchors (the URL itself). A small percentage of keyword-rich anchors is normal. A high percentage is a major red flag.
Step 4: Assess the Referring Domain Quality
A good backlink audit goes beyond just looking for toxic links. It also involves assessing the quality of your entire backlink profile. You want to understand the overall strength and authority of the websites that are linking to you.
Looking Beyond the Link to the Source
The quality of a link is largely determined by the quality of the website it comes from. A link from a high-authority, trusted website is much more valuable than a link from a small, unknown blog. This step is about evaluating the quality of your referring domains.
Analyzing Domain Authority and Trust Metrics
You can use metrics like Domain Authority (from Moz) or Domain Rating (from Ahrefs) to get a general sense of a site’s authority. You should analyze the distribution of the authority of your linking domains. A healthy profile has a good mix of links from sites with different levels of authority.
Step 5: Conduct a Competitor Backlink Analysis
You cannot properly evaluate your own backlink profile in a vacuum. You must have a point of comparison. A competitor backlink analysis provides the context you need to understand where you stand in your industry.
The Goal: Benchmarking Your Profile Against Rivals
The goal of a competitor backlink analysis is to benchmark your own profile against your top two or three SEO competitors. This will show you how your profile stacks up in terms of size, quality, and authority. This is a critical part of a comprehensive backlink audit.
How Your Link Profile Compares in Size and Quality
Use an SEO tool to compare the total number of backlinks and referring domains for your site versus your competitors. You should also compare the average domain authority of your linking sites. This will show you if you have a “link gap” that you need to close.
The process of a backlink gap analysis
A backlink gap analysis is a specific process for finding the websites that link to your competitors but not to you. This is a powerful way to find new link building opportunities. The data from this analysis can be a key output of your backlink audit.
Step 6: Create an Action Plan
The analysis phase of your backlink audit will produce a great deal of data and insights. The next step is to turn that analysis into a concrete action plan. This is where you decide what to do about the issues you have uncovered.
The “Keep, Remove, or Disavow” Framework
A simple and effective framework is to classify each of your links into one of three categories.
- Keep: These are your high-quality, relevant links that are helping your SEO.
- Remove: These are your toxic links. You will make an effort to get them removed manually.
- Disavow: These are the toxic links that you cannot get removed manually.
Building Your Disavow File
Based on your analysis, you will create a list of all the domains and URLs that you have identified as toxic and could not get removed. This list will be used to create your disavow file. The process to disavow backlinks is a powerful but advanced tactic that should be done with care.
Step 7: Executing the Cleanup Process
Once you have your action plan, it is time to execute the cleanup. This involves reaching out to webmasters to request the removal of bad links. It also involves submitting your disavow file to Google.
The Process of Manual Removal Outreach
For the links on your “Remove” list, you should reach out to the website owners. Send them a polite email asking them to remove the link. Keep a detailed record of your outreach attempts. This is an important step, especially if you are trying to recover from a manual penalty.
Submitting Your Disavow File to Google
For the links that you cannot get removed, you will use the disavow file. You will submit this file using the Google Disavow Tool. This tells Google to ignore these links when it assesses your site. This is a critical step in cleaning your backlink profile.
Step 8: Implement Ongoing Backlink Monitoring
A backlink audit is not a one-time project. Your backlink profile is constantly changing. A commitment to ongoing monitoring is essential for maintaining a healthy profile over the long term.
The Importance of Continuous Backlink Monitoring
You must have a system for continuous backlink monitoring. This is the process of tracking your new and lost backlinks over time. This allows you to spot any new toxic links as soon as they appear. It also alerts you when you lose a valuable link.
Setting Up Alerts for New and Lost Links
Most SEO tools allow you to set up automated alerts. These alerts will send you an email whenever you gain a new backlink or lose an existing one. This is the most efficient way to stay on top of the changes in your backlink profile.
