Backlinks are extremely valuable for website SEO performance. At the same time, a handful of toxic backlinks might destroy the otherwise solid results achieved through a good backlinking strategy. If you wonder whether there are toxic links in the background of your backlink profile and what you can do about them, this post is for you!
Fortunately, the toxic links in your backlink profile are not the end of the world and can be managed efficiently and professionally if you know how to do it. However, there is one thing you need to know and never forget: disavowing your backlinks should be done very carefully and rarely, as overdoing this practice can be just as bad as doing nothing at all. Read our in-depth guide to learn more about spotting and disavowing toxic backlinks.
What Are Toxic Backlinks?
Toxic backlinks are any links pointing to your website that have the potential to damage your search engine rankings rather than improve them. Such links are viewed by search engines as either unnatural, manipulative, or spammy, and therefore they reduce the trust in your website.
To spot a toxic backlink in your backlink profile, you need to understand what a toxic backlink is. It is not a link of low value, although such a link can be a problem for your SEO performance as well. A toxic link is one that poses an active threat: it signals to search engines that your website engages in manipulative practices, either consciously or subconsciously.
Why Toxic Backlinks Appear
You might ask yourself why toxic links appear in your backlink profile when you never ordered them. Here is the answer: there are several sources of toxic links.
- Outdated SEO practices
- Negative SEO attacks
- Low-quality link schemes
- Automated or scraped links
- Comment or forum spam
Understanding the origin of the link helps you better assess the situation and decide on the correct action. Scraper sites are not a big deal and are rarely a reason to act. On the other hand, links from a link farm or from a private blog network are a completely different story.
What Are the Consequences of Having Toxic Backlinks?
To understand the consequences of toxic backlinks, it is necessary to discuss two types of impact: the algorithmic one and the manual penalty issued by Google.
The Algorithmic Impact
As already mentioned above, the algorithms of Google evaluate your backlink profile according to the naturalness of your links. When a high number of links in your profile are manipulated, Google lowers the trust assigned to your site, which results in:
- Lowering of your rankings for the target keywords
- Lowering of your organic traffic levels
- Lowering of the results of your legitimate backlink building efforts
The difficulty in recognizing the algorithmic impact is that it happens gradually, and there are no announcements from Google when it happens.
The Manual Penalty
In the case of a more serious situation, you might get a manual penalty issued by a human reviewer at Google. This type of action is issued much less often and usually means:
- Significant lowering of your rankings
- The lowering of specific pages or your whole site's rankings
- The necessity to submit a reconsideration request
It is a much more serious situation, and the penalties for the violation of the linking guidelines are usually issued when deliberate manipulation is detected.
Identifying the Toxic Backlinks
If you have some suspicions about your backlinks, you can start looking for them. This is a task requiring skills and knowledge, as no single metric could help you here. Experienced professionals analyze a combination of metrics in order to determine which backlinks should be checked or eliminated.
The Symptoms of a Toxic Backlink
While analyzing your backlink profile, pay attention to the links displaying one or several of the following symptoms:
- Irrelevant source site: a link to a dental clinic from a gambling website is a signal of manipulative practices.
- Low-authority or spammy domain: a site that has little or no legitimate traffic and no legitimate content.
- Over-optimized anchor text: a large number of links pointing to your site with an exact-match keyword as anchor text.
- Link from a known link network: a private blog network (PBN) or a link farm that sells links.
- Sitewide link: the same link displayed in the footer or sidebar of every page on the website.
- Foreign-language domain unrelated to your market: links to your website from a website in a language and region that have no relation to your target audience.
- Link from a flagged or penalized domain: a site that was itself penalized by the search engines.
- Sudden unnatural spikes of links: this could be a sign of a negative SEO attack or a link-buying campaign.
The Tools That Could Help You
To analyze your backlink profile and find the suspicious links, there are several tools that could help you with this task:
- Google Search Console: it gives you an overview of the links pointing to your website and alerts you about manual actions.
- Ahrefs, SEMrush, or Moz: these give you authority metrics and detailed information about your backlinks.
- Special toxicity checker tools that give a "toxicity score" for each link.
Although the mentioned tools could help you find and prioritize the suspicious links, they are tools of support and not the definitive authority. The "toxicity score" calculated by these tools is just the initial step of analysis and not the final one.
The Difference Between Low-Quality and Toxic Links
This differentiation is crucial, as a mistake in the evaluation could cost you your ranking positions.
Low-Quality Links
Low-quality backlinks are the links to your website that do not have a significant influence on your search engine rankings, although these links are not beneficial. It could be a link from a small blog or directory, or a link to a low-traffic page. In most cases, the right action for this type of backlink is to do nothing. Google ignores them, and it makes no sense trying to remove them, as it provides no benefits.
Toxic Links
This is a link with active risk: it is a part of a link scheme, it is from a penalized or malware-infected site, or it is obviously a paid or over-optimized link. These links should be monitored and, possibly, disavowed.
The ability to differentiate low-quality links from toxic links is a crucial skill, and confusing the two is the most common and costly mistake made by webmasters.
When Is It Necessary to Disavow Backlinks?
Now it is time to talk about the most controversial question concerning backlink management: when it is necessary to disavow the backlinks.
The Times When It Makes Sense to Disavow Backlinks
There are certain situations when disavowing the backlinks is a must:
- You got a manual penalty for unnatural links and you cannot remove them by contacting the site owner.
- You are the target of a negative SEO attack with a large amount of obviously spammy and manipulative backlinks.
- You have a legacy of manipulative links from your own or another agency's SEO practice that violate Google's guidelines and cannot be removed manually.
In these cases, it is a necessary step to be undertaken to resolve your problem.
The Times When You Should Not Disavow
Just as important as knowing when to disavow the links is understanding the situations when this action is unnecessary:
- You have low-quality but non-harmful links. In this case, Google ignores them.
- You are reacting to the automatically calculated toxicity score.
- You do not have a manual penalty and your rankings are healthy.
- You are not sure whether the backlinks are truly toxic and need to be disavowed or not.
The Correct Approach to Handling Toxic Backlinks
When you have identified links that you need to do something about, you need to follow a certain procedure.
Step 1: Conduct the Backlink Audit
Before doing anything else, you should conduct a thorough backlink audit. In this process, you need to pull the data from various sources and analyze all your backlinks.
Step 2: Categorize All Backlinks
After the initial analysis, it is important to sort your links into several groups:
- Healthy links that need to be preserved
- Low-quality but non-harmful links that should be left intact
- Toxic backlinks that need to be removed or disavowed
This categorization is the point where the professional's experience is extremely useful, as sometimes it is not easy to separate "harmless" links from toxic ones.
Step 3: Try Removing Links First
The first step to undertake for the removal of toxic links is the attempt to reach the owners of the site and ask them to delete the links to your website. Actually, Google prefers this method, as it demonstrates good faith. It is not always possible, and it is time-consuming, but it is the most elegant way to solve the problem.
Step 4: Use the Disavow Tool When It Is Needed
When the removal attempt fails, or the volume of toxic links is too large to attempt the removal manually, you can use the disavow tool:
- Make sure you format the file properly. This is very important to avoid mistakes.
- Disavow the links at the domain level if necessary.
- Make sure to keep detailed logs of all your disavowed links.
- Do not disavow the links you want to preserve.
Step 5: Monitor the Results of Your Action
The disavow file submission is not the final step of the process. After submitting, monitor your rankings and traffic, and be ready to revise your decision if needed.
How to Prevent Toxic Backlinks in the Future
It is much easier to prevent the appearance of toxic backlinks than to try to fix them. Here are the preventive measures that you can apply.
Apply the Good Practices of Link Building
First of all, you should be very careful when building the backlink profile of your website, as the link quality directly depends on the link-building practices.
- Pay attention to the relevancy and authority of the source sites you want to obtain links from.
- Do not buy cheap link packages, as in 99% of cases they are toxic.
- Focus on editorial links, the links gained organically.
- Diversify your backlink profile.
Monitor Your Backlink Profile Regularly
Even having applied the good practices of link building, it is reasonable to monitor your backlink profile regularly. Such regular reviews will allow you to discover a problem early and prevent possible issues.
Why Professional Help Is Important
Backlink management, identification of toxic links, and understanding of the situations requiring disavowal is a skill-based process. The stakes are quite high, as an inappropriate action could seriously affect the performance of your website. The professionalism of a link building agency could play a crucial role in avoiding this trouble.
A professional agency offers the following services that help to manage your backlink profile successfully:
- The proper judgment of the backlinks thanks to accumulated experience
- A proper backlink audit with a comprehensive analysis of backlinks from different sources
- Careful and conservative use of the disavow tool in order to protect the authority of your website
- Proactive and ethical link building
- Regular monitoring of your backlink profile
- Peace of mind
The importance of professional judgment in this case cannot be overestimated, as the difference between the competent professional who knows that a certain backlink is not toxic and the nervous DIYer who disavows everything flagged by a tool is enormous.
Key Takeaways
Let's summarize everything we've said.
- Toxic backlinks are links that potentially harm the rankings of your website, rather than links that simply have no value.
- Google often ignores low-quality backlinks automatically, so there is no need to panic.
- Identification of toxic backlinks should be done with the help of professional judgment and not the automatically calculated toxicity score that frequently provides false positives.
- The disavow tool is a powerful weapon and should be used only in the case of manual penalties, negative SEO attacks, or a legacy of manipulative links.
- Disavowing good links by mistake could harm you, so every action should be undertaken with care.
- It is better to prevent the problem than to struggle with it, and ethical link building prevents it effectively.
Conclusion
A healthy backlink profile is an asset of huge value for your SEO performance, and protecting it is an important part of your strategy. However, its protection does not mean hunting for links to disavow, but proper link building and management instead.
Toxic backlinks require a lot of experience to handle, and disavowing of the links should be done carefully and rarely. Websites that will succeed in managing backlinks will be the ones that invested in ethical and high-quality link building from the very beginning, kept control of the profile, and relied on professionals for making complex decisions.
