Step 1: Look at Competitor Backlinks
To find new link opportunities and understand your competitors' strategies, analyze their backlink profiles. Here's how:
Check Domain Stats
Look at key metrics like Domain Rating (DR), referring domains, and total backlinks. This shows how your site's backlink strength compares to competitors:
| Metric | Description |
|---|---|
| Domain Rating (DR) | A score predicting how well a site will rank. Higher DR means more backlink authority. |
| Referring Domains | The number of unique websites linking to the domain. More referring domains = more authority. |
| Total Backlinks | The total number of backlinks pointing to the domain from all sources. |
Use tools like Ahrefs, Semrush, or Moz to easily find these metrics for your competitors. Compare the numbers to see if you're ahead or behind in overall backlink strength.
Find New Link Chances
The real value is finding sites linking to competitors but not you. These represent prime link building opportunities to get similar high-quality backlinks.
Most SEO tools offer a "Link Intersect" or "Link Gap" feature to quickly find untapped backlink sources:
- Enter your domain and your top competitors' domains.
- The tool shows websites linking to competitors but not you.
- Analyze these sites - look at DR, relevance, traffic stats, etc. to identify the best prospects.
- Prioritize getting backlinks from these sites through tactics like content outreach, guest posting, broken link building, etc.
Step 2: Track Backlink Growth
Monitoring your backlink profile's growth is crucial for understanding the effectiveness of your link-building efforts and overall SEO performance. By tracking backlink growth, you can gain valuable insights into the pace at which you're acquiring new links and identify potential issues or opportunities for improvement.
Monitor Referring Domains
Tracking the progression of referring domains over time helps evaluate the diversity and authority of your backlink profile. A steady increase in referring domains indicates that your content is resonating with a wider audience and attracting links from various sources, which can positively impact your search engine rankings.
| Metric | Description |
|---|---|
| Referring Domains | The number of unique websites linking to your domain. More referring domains = more authority. |
Use backlink analysis tools like Ahrefs, Semrush, or Moz to generate reports on referring domains. Analyze these metrics to identify patterns, such as a sudden spike or drop in referring domains, which may indicate the need for adjustments to your link-building strategy.
Check New and Lost Backlinks
In addition to monitoring referring domains, it's essential to keep track of newly acquired and lost backlinks. This information helps you understand your link churn rate, which is the rate at which you gain and lose backlinks over time.
| Type of Backlink | Description |
|---|---|
| New Backlinks | Newly acquired backlinks from various sources. |
| Lost Backlinks | Backlinks that have been removed or devalued by search engines. |
Use backlink analysis tools to generate reports on new and lost backlinks, and review these reports regularly. Pay close attention to the quality of the new backlinks you're acquiring, as well as the reasons for any lost backlinks. This information can help you refine your link-building tactics and ensure that you're focusing on acquiring and maintaining high-quality, relevant backlinks.
Step 3: Manage Backlink Loss
Backlink loss is a natural part of the SEO process. Websites constantly update their content, and links can become broken or removed. Identifying and mitigating this loss is crucial for maintaining a thriving backlink profile and ensuring ongoing authority and search ranking.
Reasons for Backlink Loss
Backlink loss can occur due to various reasons, including:
- Website redesigns or content consolidation
- Broken links due to URL changes
- Link removal by the referring website
- Penalties from search engines for low-quality or spammy backlinks
Calculating Link Churn Rate
The link churn rate measures the percentage of backlinks lost over a specific period. Calculating this rate helps you understand the health of your backlink profile and identify potential issues.
| Step | Description |
|---|---|
| 1 | Determine the time period to analyze (e.g., monthly, quarterly, or annually). |
| 2 | Record the total number of backlinks at the beginning of the period. |
| 3 | Record the total number of backlinks at the end of the period. |
| 4 | Subtract the number of lost backlinks from the initial total. |
| 5 | Divide the number of lost backlinks by the initial total. |
| 6 | Multiply the result by 100 to get the link churn rate as a percentage. |
For example, if you had 1,000 backlinks at the start of the month and lost 50 by the end, your link churn rate would be:
(50 / 1,000) x 100 = 5%
A high link churn rate (e.g., above 10%) may indicate issues with your backlink profile that need to be addressed.
Step 4: Remove Bad Backlinks
Toxic backlinks from low-quality, irrelevant, or spammy websites can harm your site's SEO performance. Identifying and removing these harmful links is crucial for maintaining a healthy backlink profile. Here's how to audit and eliminate bad backlinks:
Check Referring Domain Quality
Analyze the list of domains linking to your site. Look for signs of low-quality or spammy websites, such as:
| Signs of Low-Quality Sites | Description |
|---|---|
| Excessive ads or affiliate links | Too many ads or affiliate links can indicate a low-quality site. |
| Thin, duplicated, or auto-generated content | Poor content quality can be a sign of a spammy site. |
| Unrelated or irrelevant topics | Sites with unrelated topics may not be relevant to your audience. |
| Low domain authority/page authority scores | Low authority scores can indicate a low-quality site. |
Use tools like Ahrefs, Moz, or Majestic to analyze the quality and relevance of referring domains. Prioritize removing links from sites with poor metrics.
Check Anchor Text Relevance
Analyze the anchor text distribution of your backlinks to detect over-optimized or unnatural patterns, such as:
| Unnatural Anchor Text Patterns | Description |
|---|---|
| Exact match keywords repeated excessively | Too many exact match keywords can be a sign of manipulation. |
| Irrelevant or unrelated phrases | Unrelated phrases can indicate a low-quality link. |
| Suspicious terms like "click here" or "website" | Suspicious terms can be a sign of a spammy link. |
While some keyword-rich anchors are expected, an excessive amount or clear manipulation could signal spammy link building practices that should be addressed.
Look at Top-Level Domains
Examine the top-level domains (TLDs) of your backlink sources. An unusual concentration of links from a specific TLD, especially from country-code TLDs irrelevant to your target market, may indicate link networks or other black-hat SEO tactics.
Once you've identified toxic backlinks through these methods, you can take action to remove or disavow them, protecting your site's search engine visibility and rankings.

Step 5: Check DoFollow vs. NoFollow Links
Maintaining a healthy balance between dofollow and nofollow backlinks is crucial for effective SEO. Dofollow links pass link equity (ranking power) to the linked page, while nofollow links do not. A higher proportion of dofollow backlinks can positively impact your search engine rankings.
Review Link Attributes
To evaluate the dofollow/nofollow ratio in your backlink profile, follow these steps:
- Use Backlink Analysis Tools Use tools like Ahrefs, Semrush, or Moz to get a comprehensive list of your website's backlinks. These tools can identify whether a link is dofollow or nofollow, allowing you to filter and sort accordingly.
-
Inspect Link Source Code Alternatively, you can manually inspect the source code of pages linking to your site. Right-click on the link and select "Inspect" or "View Page Source." If the link contains
rel="nofollow", it's a nofollow link. If there's no such attribute, it's a dofollow link.
Monitor the Ratio
Aim for a higher percentage of dofollow links compared to nofollow links. While a diverse backlink profile with some nofollow links is natural, an excessive number of nofollow links can limit the SEO benefits you receive.
| Link Type | Description |
|---|---|
| Dofollow Links | Pass link equity (ranking power) to the linked page. |
| Nofollow Links | Do not pass link equity (ranking power) to the linked page. |
Prioritize High-Authority Dofollow Links When link building, prioritize acquiring dofollow backlinks from high-authority, relevant websites within your industry. These links carry more weight and can significantly boost your search engine visibility.
Step 6: Balance Referring Pages and Domains
To maintain a healthy backlink profile, it's essential to have a balanced ratio of referring pages to referring domains. This balance indicates that your content is attracting natural links from various sources, which is a positive signal for search engines.
Ensure Backlink Diversity
Aim for a diverse distribution of backlinks across multiple referring domains and pages within each domain. Here are some tips to achieve a balanced and diverse backlink profile:
| Tip | Description |
|---|---|
| Monitor Referring Pages per Domain | Track the number of referring pages from each linking domain. |
| Analyze the Distribution | Evaluate the distribution of referring pages across your top linking domains. |
| Identify Potential Imbalances | Check for an excessive number of links coming from a single page or a small set of pages within a domain. |
| Diversify Link Sources | Actively seek backlinks from a wide range of relevant and authoritative domains within your industry. |
| Focus on Quality Content | Create high-quality, valuable content that naturally attracts links from various sources. |
