  2. Review the Backlink Profile List
  3. Identify Your Unnatural Links
  4. Measure Penalty Risks
  5. Remove Bad Links and Disavow

Step 1. Get to Know All the Links of Your Site

To run a comprehensive backlink analysis you need the have access to the whole list of links. The easiest way to do this is by using a link audit tool. Such tool will only require that you just add your website and instantly get a list with all of your links.

If you want to be extra sure that everything is in, you can always import link within the tool. Simply use Google Analytics and Google Webmaster Tools (Search Console) to download the list of links from there. Using the old version or Google Search Console you can download the data for your site, by going to Search Traffic » Links to Your Site. If you chose the option to “Download latest links” you’ll get the whole list of links and not only the domains.

You can get a list of links from Google Analytics, but you’ll need a script. If you’re tech-savvy. You’ll have to add a short, simple code in your Google Analytics Tracking code.

Sean Si, an SEO Specialist, explained in one of his articles how to track outbound links using Google Analytics through a code. You have to copy-paste the next code and put it exactly under your Google Analytics tracking code in the same script:

Then you can review your outbound links. Go to Behavior » Events » Overview. And look at the List of links from the right side:

You can collect all the links in one single file. Make sure that you add the extra links you might have form our sources and place them into the SEO audit tool. Besides all the links that the tools show you, it will be a great benefit to add all the other ones gathered through manual actions.

Step 2. Review the Backlink Profile List

Once you got here, you need to have a strategy in mind. Before going into specifics, you need to evaluate your links together as a unitary piece and identify strengths and weaknesses for the whole backlink profile.

The process should take into consideration the following steps:

  1. Identify the Domain Authority and Link Profile for each website by looking at referring domains & analyzed links.
  • check link rank (scale 0-100): a popularity score developed by us to see the quality of the overall link profile. The higher the score, the higher the quality.
  • the number of referring domains that are analyzed by the system/the number of referring domains the website has.
  • the number of links analyzed by the tool/the number of links that the website has.

The number between the referring domains and links might be different. Multiple links from the same domain are considered to transfer lower value, so unique linking referring domains are typically a more relevant metric.

  1. Check the natural growth of your backlink profile by reviewing the Link Velocity. The link velocity chart is a good indicator for spotting spikes and drops for links and referring domains.

The chart shows the cumulative total number of analyzed links and the number of referring domains existing into the system. In case you see huge spikes for links versus referring domains (or a spike of one of the two) that could mean the website had some unnatural growth, or massive link building campaigns. And those links should be analyzed in detail in the next step of the link audit – Unnatural link Detection.

  1. Compare dofollow links to nofollow links. While both links are good and they enrich your backlink profile, you can review both of them to have an accurate view. A natural link growth can’t show only a single type of links.

You should raise a flag in case you don’t have nofollow links or have too many. In the first scenario, if you don’t have nofollow links, it means the links were acquired in an unnatural way and the website needs further analysis to spot and remove the spammy links.

If you have too many nofollow links, then you should start generating dofollow links and create a new strategy.

  1. Check the authority distribution of your backlink profile. Inbound Link Analysis shows information about the type of influence for all of your links.

It is natural to have low and no authority linking pages because the web itself is formed of a very high distribution of high and low-quality pages.

  1. Understand the website coverage of your links by reviewing side-wide links. Site-wide links are replicated on several (or all) pages of your site. For example, the footer or blog-roll links are site-wide links. Not all of them have value for your analysis, so you can filter them out.

You should have fewer sitewide links because they are not so relevant for your website and have low-quality.

  1. Evaluate the Deep Link Ratio and check how many backlinks are pointing to your homepages. You should see exactly if you are having links coming to specific pages to spot the spammy path. It is OK to have both of them within your distribution.

A Link Explorer can quickly show why links to other pages than the homepage are important and how they help boost the overall authority of a website. You can see that all the backlinks pointing to the internal pages of a website are connected and are reinforcing the main domain.

Link Explorer has lots of other advantages. You can also find the best internal pages.

  1. Easily find the strongest internal pages you have, based on high-quality backlinks using a Link Explorer.

The lowest-quality backlinks are represented by the smallest dots, the ones that are the closest to center of the cluster. And the highest-quality links are represented by the largest dots, farthest from the center of a cluster. So it’s really easy to analyze your high-quality link ratio and also identify your best linked internal pages.

  1. Check how many backlinks are coming from homepages versus deep page.. In this case, you can see if the links you receive come from the homepage or from a specific URL. The desired option would be to have a smaller amount of homepage backlinks than deep backlinks.

The explanation is pretty simple. Very few websites have links on their homepage that point to a foreign website because that is a presentation page about a business/company. So, one of the few exceptions happens when those links are placed there with a paid agreement.

A natural situation would be to have links on deep pages, just like somebody would link to your website on one of their articles to recommend something that you have or give a reference.

  1. Analyze the relevance between a site and its inbound links. You can use this to see if you have links placed on sites that are totally out of your niche and that could affect your rankings negatively.

A more in-depth look should be applied to categories such as Gambling, Adult, Pets because it might not be related to the niche they are focusing on.

Link Visibility charts helps you spot unnatural link footer patterns very easy. You can identify the visual location of the links on the page. You can see three types: above the fold, body, and footer. Normally, you should have a lot of body links (links placed inside the page – usually in the content) and not header or footer links.

  1. Reveal any link building strategy. In case you want to see what strategies were implemented, you can use the Webpage Type & Link Positioning data.

The Webpage Type chart allows you to profile your backlinks. This means you can see exactly the type of page it’s linking to, whether it’s a Blog, a Forum, an E-commerce site or maybe a News site. The classification can really come in handy if you want to see the linking strategy for that specific website.

Link Positioning classifies each analyzed link by its type (Blogroll, Blog Post, in Content Link, etc.). Some of the worst examples are blog comments and the banner type of links.

  1. Identify new markets & unnatural linking patterns. Since we’ve talked about future strategies and marketing plans, the final metric to use for a link analysis is Webpage Language & Domain TLD Distribution.

The Webpage Language classifies each page by the main language that the content was written in. The Domain TLD Distribution displays how the referring domains are distributed across the entire link profile, based on their TLD (Top Level Domains).

They both work together. To spot any irregularities, check pages written in languages that have no connection with your site. For example, you have a website that targets the US market but most of the links came from Chinese websites, written in Chinese. So use Google translate in case you find something unnatural.

You can easily spot the country by looking at the Top 10 Referring Countries.

The next point on the link audit will conclude with a clearer perspective of your backlink profile.

  1. Understand the evolution of any website. This can complement your reports very well.

The Link History chart shows your links categorized.

  • see daily new and lost links to see the days (periods) where you received or lost a larger amount of links. You can identify issues by looking at the spikes. 
  • see the evolution of your links and referring domains.
  • manage your link profile unnaturalness over time and the risk of your website being penalized by the search engines.
  • take action in case you have lots of lost links.
  • find the link building strategies for each website and how they evolved.
  • see where your links are coming from.

The Anchor Text History shows you the evolution of the anchor texts for the live and lost links. This chart is very good for spotting any spikes which stand out from all of those that have constant evolution.

Step 3. Identify Your Unnatural Links

There are lots of features in SEO audit tools  that help you trace unnaturalness.

One of the main features is the Unnatural Link Detection which will discuss a little bit further and it can point you to the unnatural and suspect links for every website you might have and also give you indications of how ok or not is your backlinks profile. 

Before you get to the Unnatural navigator, there other features that can give you direct indications to which pages you receive spammy links. 

One of them is the Link Explorer, which helps you uncover any website’s link profile. You can see them classified by unnaturalness and see if you have pages with problems.

Before reviewing the unnatural links one by one or in bulk (as you wish), you need to classify the brand vs. commercial anchor text.  The Anchor Text Distribution is your help. It is very good for spotting any suspicious anchor texts which are out of the niche.

You’ll see three types of anchor texts:

  • brand: classify all the anchor texts that contain the name of the brand or similar variations.
  • commercial: include anchor texts that describe the brand, the services/products, the industry or type of business. In one word, keywords that have commercial intents.
  • miscellaneous contains keywords that you should place in one of the categories described above. Usually, in the gray area there must remain only informational keywords, such as “click here”, “website”, “source”, etc.

There are three categories of links: Suspicious and unnatural and to each category the number of links is attached. The desired situation would be to have more OK links.

If you have a backlinks profile with a percentage or unnatural links that is higher than 15%-20% then you might be in trouble. You’ll get a warning message saying:

This site has a highly unnatural link profile and it’s likely to be penalized by Google. You should use the Link Navigator in order to mark the unnatural links for Disavow or Removal.

Step 4. Measure Penalty Risks

Once you’ve seen the starting point of your unnatural links, you can measure the penalty risk. Look for any unnatural link signals by evaluating the issues so you can clean your backlinks profile and have a healthy status. The tool shows you some of the reasons why some of your links are considered to be unnatural or potentially dangerous.

Google says it very clear that any link that manipulates ranking in Google search results may be considered part of a link scheme and a violation of Google’s Webmaster Guidelines. Quality is defined as follows:

The best way to get other sites to create high-quality, relevant links to yours is to create unique, relevant content that can naturally gain popularity in the Internet community. Creating good content pays off: Links are usually editorial votes given by choice, and the more useful content you have, the greater the chances someone else will find that content valuable to their readers and link to it.

Your link audit tool must follow the quality guidelines form Google and mark links as unnatural if the website follows any of the next strategies:

  • it comes from automatically generated content;
  • are generated by a paid contract (buy and selling links type of schemes);
  • pages created with little or no original content;
  • cloaking;
  • manipulated redirects;
  • hidden text or links;
  • doorway pages;
  • scraped content;
  • keyword stuffing and pages loaded with irrelevant keywords;
  • pages that use malicious (phishing or installing viruses, trojans, or other badware)
  • abusive rich snippets markup and so on.

Step 5. Remove Bad Links and Disavow

When you find bad links, the best decision would be to disavow them. The Unnatural Link Detection allows you to easily disavow, add them into a file and then send the file directly to Google. They recommend it. If you find any bad links, the best to do is disavowing them, to cut the connection with your website. 

After disavowing the links, go to the main page of the tool and click on Export Google Disavow and then Send disavow file. In case you have a disavow file, you can add it to the tool by clicking on Import Google Disavow and then collect others links.

Step 6. Compare Links to Your Competitors for a Deeper Competitive Analysis

You can perform individual analysis for each competitor or side by side comparison.

The Webpage Type that we’ve previously talked on the analysis for your own website has a lot of benefits for spotting the strategies applied by your competitors. It has a strong value because you can use these metrics for spotting the strategies followed by your competitors determining which type of sites seems to be more likely to link to you, based on your competitors’ profiles.

The Link Positioning data is highly beneficial to spy on your competitors and get some directions for your website (pros versus cons). Running a backlink analysis of your competitors allows you to find out where they’re hiding their most valuable links. Once you’ve figured it out where they’re getting traffic from, you can use those data to create a top-notch link building strategy for your site. Along with that, you can also take advantage of the timeline analysis to see the evolution of your site and your competitors’ sites.

Step 7. Start a Strategy for Building Valuable Links

For a valuable addition to your backlinks profile, find new opportunities form your competitors.

Click on the uncommon links from your competitors because those are the links they have and you don’t, but could acquire and check the list. Make sure you order them by the Rating to see the best websites on the top.


The link auditing process presented doesn’t have to include all the steps, and of course, you can mix and match until you find the best option for you.
