Understanding the Impact of Bad Backlinks on Your Website’s SEO


Share on

Bad backlinks can sink your website’s SEO, overshadowing the hard work you put into building visibility online. As crazy as it sounds, all it takes is one suspicious link and you’ll be in Google’s crosshairs, which can mean anything from a temporary penalty to permanent deindexing. 

This guide cuts through the complexity to focus squarely on understanding and dealing with these detrimental links. 

We’ll cover how to spot a bad backlink, the damage they cause, and effective removal strategies. Armed with the right information, you can safeguard your site’s SEO integrity and keep your backlink profile strong. Dive in to turn the tide against bad backlinks and secure your online presence.

What Are Backlinks?

Backlinks, fundamentally, are links from other websites that lead back to your site. They are the digital endorsements or votes of confidence that signal to search engines like Google that others find your content valuable and relevant. Each backlink has several key components:

  • Anchor text: Anchor texts that accurately describe the linked content’s topic or keywords can enhance SEO by providing clear signals to search engines about the content’s relevance. However, over-optimizing anchor text with exact match keywords can be seen as manipulative, potentially leading to penalties.
  • DR: Domain Rating (DR) is a metric developed by Ahrefs to gauge the strength of a website’s backlink profile on a scale from 0 to 100. Backlinks from high-DR websites are more valuable, as they pass more “link juice” or authority to your site. 
  • Relevance: The relevance of a backlink is determined by how closely the content on the linking site relates to your site’s content. Search engines prioritize links from sites within the same industry or niche, as these are seen as more authoritative and beneficial.

On the surface, backlinks serve a very particular purpose — to fill out existing content with additional information. Whether it’s because the linked content is supplementary or because the word count is too restrictive, blogs and articles wouldn’t be what they are without this ‘cherry on top.’ 

Importance of Backlinks in SEO

In the realm of SEO, backlinks serve as a critical metric for the ranking algorithm of search engines. They not only indicate the popularity or importance of your website but also contribute to the authority and trustworthiness of your site. 

PR links

Search engines view each backlink as a form of endorsement. Think of it like this — if your blog appears on Wikipedia or in a New York Times article, that means it’s valuable content. And then, automatically, Google will push that content higher up the SERPs, which creates a snowball effect. 

Types of Backlinks

Upon us mentioning DR and other metrics, you’re probably thinking “Oh good, I’ll just get onto some DR90+ sites and I’ll be #1 on Google, easy!” Not quite, unfortunately. Aside from merely observing the authority factor of the site, Google prefers organic backlink profiles. As such, these profiles must include different types of links, mainly: 

  1. Good Backlinks: Originating from reputable, high-authority websites that are relevant to your niche, good backlinks can significantly boost your site’s search engine rankings. They are typically characterized by their natural acquisition, relevance to the linked content, and the use of proper anchor text that reflects the content’s context without appearing manipulative.
  2. Neutral Backlinks: These links come from legitimate sites but might not have high authority or direct relevance to your niche. They contribute to a more diverse backlink profile and can bring in traffic, but they don’t significantly impact your SEO rankings.
  3. Bad Backlinks: Coming from low-quality or spammy websites, often in completely unrelated niches or from known link farms, these links are nothing by trouble. In fact, it’s a common black-hat SEO strategy. 

The Impact of High-Quality vs. Bad Backlinks

The distinction between high-quality and toxic backlinks isn’t just academic; it’s a critical factor in your site’s search engine performance. 

High-quality backlinks from authoritative, relevant sites signal to search engines that your content is valuable, credible, and worth ranking highly. These endorsements enhance your site’s authority, driving up rankings, and increasing visibility. They can come from organic relationships or manual link building services

Conversely, bad backlinks send red flags to search engines, suggesting that your site might be engaging in spammy or manipulative SEO practices. This can lead to a range of negative outcomes, from a drop in rankings to being penalized by search engine algorithms like Google’s Penguin. 

Good Backlinks vs. Bad Backlinks

Such penalties can be difficult to recover from, underscoring the importance of regularly monitoring your backlink profile and taking proactive steps to disavow or remove harmful links.

Identifying Bad Backlinks

When it comes to battling bad backlinks, the best remedy is to be on the lookout and notice them right away. While some, like those built by competitors to sites with explicit or illicit content, are more blatant and apparent, the majority of backlinks are much more low-key. However, you can still notice them by the following: 

  • Irrelevant Content: Links from websites unrelated to your site’s content typically don’t add value and may suggest spammy link-building practices. Relevance is crucial, as search engines prioritize backlinks that are contextually related to the content they point to.
  • Low-Quality Domains: Domains known for spam or low-quality content, including link farms, can negatively affect your SEO. These sites often have a disproportionate number of outbound links compared to inbound links, undermining their authority.
  • Suspicious Anchor Text: Anchor text that is overly optimized or generic can indicate manipulative link-building efforts. A healthy backlink profile features a variety of anchor texts that accurately reflect the content or context of the links.

Tools and Techniques for Detection

While these factors we mentioned are easy to spot in a vacuum, they’re just one aspect of link building, and it’s easy to get flustered when looking for toxic backlinks. Thankfully, software such as Ahrefs, SEMrush, and Moz provide extensive backlink analysis capabilities. In just a few clicks, you can assess the quality and relevance of linking domains through metrics like domain rating (DR) and page authority (PA), highlighting potentially harmful backlinks.


Beyond automated analysis, manual audits offer a granular look at backlinks. Reviewing links individually for relevance, domain credibility, and anchor text naturalness provides a comprehensive understanding of backlink quality. Though labor-intensive, manual reviews are the most detailed method for spotting problematic links.

And last but not least, consistent monitoring of your backlink profile is crucial. Staying ahead of potentially damaging backlinks minimizes their impact on SEO. Setting alerts for new backlinks using SEO tools can keep you informed of changes to your backlink landscape.

Google’s Algorithm Updates and Backlinks

Google’s search engine algorithms have undergone significant transformations since the company’s inception, each update aiming to refine and improve how websites are ranked based on relevance, quality, and user satisfaction. Among these updates, some have specifically targeted bad backlinks, mainly: 

Google Algorithm Updates
  • Panda (February 2011): Introduced to penalize sites with low-quality content, indirectly affecting backlinks by diminishing the value of links from such sites.
  • Penguin (April 2012): Directly targeted at decreasing rankings of sites that violate Google’s Webmaster Guidelines, especially those involved in manipulative link schemes and keyword stuffing. This update significantly changed the backlink landscape by penalizing bad backlinks.
  • Hummingbird (August 2013): Focused on improving search queries’ understanding and providing engine results that matched searcher intent rather than individual keywords. While not directly targeting backlinks, it influenced the types of content that earned valuable backlinks by prioritizing comprehensive, contextually relevant content.
  • Pigeon (July 2014): Aimed to improve local search engine results, it indirectly affected backlinks by emphasizing the importance of local directories and places where high-quality local backlinks could be earned.
  • Fred (March 2017): Targeted at sites that violate Google’s webmaster guidelines. Although not explicitly detailed by Google, observed impacts include penalties on sites with low-quality content and aggressive monetization, affecting the value of their backlinks.
  • BERT (October 2019): Aimed to better understand natural language processing, BERT impacts how backlinks are evaluated in terms of content relevance and quality surrounding the link context.
  • Page Experience Update (June 2021): Google introduced core web vitals as ranking factors, focusing on user experience metrics like loading performance, interactivity, and visual stability. Although not directly targeting backlinks, this update reinforced the significance of user-centric websites, indirectly influencing site authority and possibly backlink quality.
  • Spam Update (2022): Google continued its efforts to combat webspam and low-quality content, refining its algorithms to better detect and penalize manipulative link-building tactics. This update aimed to further diminish the impact of unnatural backlink profiles, focusing on improving search result quality.
  • November Reviews Update (November 2023): Google introduced the standalone November Reviews Update, indicating a shift towards continuous evaluation of review content quality. This update underscores Google’s commitment to ongoing assessment and improvement of review-related information.

Bad Backlinks Negative Impact on SEO

Contrary to popular belief, bad backlinks’ impact on SEO goes far beyond being a simple nuisance. While a re-syndication gone wrong can take time to rectify through Ahrefs or Google Analytics, the real consequences can be much more grim. 

Bad backlinks can lead to a significant drop in search rankings. Search engines, aiming to deliver the most relevant and high-quality content to users, penalize sites with manipulative or spammy backlink profiles.

A direct consequence of decreased search rankings is the loss of organic traffic. As your site moves down in search engine results, fewer users will click through to your site. This reduction in traffic can significantly affect your website’s performance, especially if organic search is a primary source of visitors.

Likewise, search engines and other websites may perceive your site as less trustworthy if it’s associated with spammy or irrelevant sources. This perception can hinder partnerships, collaborations, and the overall credibility of your site.

In severe cases, search engines may choose to deindex pages—or even entire websites—that are found to have a high volume of bad backlinks

These penalties are more severe than algorithmic adjustments and require direct action to resolve. And if you end up getting a penalty notification from Google, it’s already too late. That’s why disavowing should be the core of your link building arsenal. 

The Disavow Tool: Remove Bad Backlinks from your Backlink Profile

Since Google is aware of black-hat SEO practices and the ambiguous nature of SEO, they allow webmasters to effectively say “We don’t want to be associated with this website.” Within just a few simple steps, you can basically order Google to ignore bad backlinks and maintain the spotlessness of your backlink profile. 

  1. Conduct a backlink audit: Start with a thorough analysis of your backlink profile to identify any detrimental links. Employing SEO tools can streamline this process, facilitating a comprehensive review based on the metrics of relevance, quality, and credibility of the linking domains.
  2. Manual removal efforts: Before turning to the Disavow Tool, attempt to remove unwanted backlinks manually. Try contacting the webmasters of the linking sites to request the removal of the links. Google expects webmasters to make reasonable efforts to remove harmful links manually before submitting a disavow request.
  3. Prepare a disavow file: Assemble a .txt file listing the URLs or domains you wish Google to ignore, adhering to Google’s formatting guidelines. This file should include one URL or domain per line, utilizing “domain:” to indicate the disavowal of all backlinks from a particular domain.
  4. File Submission: Through the Google Search Console, upload your prepared .txt file to the Disavow Links tool associated with your website. After submission, Google processes the file and, over time, excludes the specified backlinks from its assessment of your site.

Applying the Disavow Tool demands careful consideration to avoid inadvertently excluding beneficial backlinks. It’s advised to disavow links that are unequivocally spammy, of low quality, or in violation of Google’s Webmaster Guidelines. Even if you don’t like a link, but it isn’t spammy, leave it be to maintain a healthy backlink profile. And speaking of which…

Building a Healthy Backlink Profile

Becoming adept at backlink management involves not only the removal of harmful backlinks but also the proactive acquisition of links that enhance your site’s authority and visibility. After all, the healthier your backlink profile is, the less apartment and damaging backlinks can be. To achieve optimal backlink profile healthiness, you can always: 

  • Submit guest posts: Writing articles for other websites in your industry can provide valuable backlinks to your site. This method not only helps in building backlinks but also positions you as an authority in your field.
  • Build PR links: Leveraging public relations to get mentions and backlinks from news sites or industry blogs can significantly boost your site’s profile.
  • Offer your content in place of broken links: Identifying broken links on other sites and offering your content as a replacement can be an effective way to gain backlinks.
  • Turn your content into resources: Getting your site listed on resource pages relevant to your niche can drive both traffic and link equity to your site.
  • Reclaim lost links: Reclaiming lost backlinks, either by fixing broken links to your site or reaching out to webmasters where links have been removed, can help maintain your link profile’s strength.

How does Google evaluate backlinks?

Google evaluates backlinks based on their quality, relevance, and the authority of the linking site.

Google’s algorithms, especially after updates like Penguin, are designed to penalize sites with manipulative or spammy backlink profiles.

Can you explain the different types of backlinks?

Backlinks can be categorized into dofollow and nofollow links, with dofollow links passing on link equity and nofollow links not directly influencing search engine rankings. The quality of backlinks also varies, ranging from high-quality links from authoritative sites to low-quality links from spammy or irrelevant sites.

How can I identify bad backlinks on my website?

Identifying bad backlinks involves analyzing your backlink profile using SEO tools like Ahrefs, SEMrush, or Moz. Look for links from low-quality, irrelevant sites known for spammy practices. Regular audits of your backlink profile are essential for identifying and addressing these harmful links.

How does the Google Disavow Tool help remove bad backlinks?

The Google Disavow Tool allows webmasters to inform Google about backlinks they believe are harmful and wish to disassociate from their site.
