For any SEO, high-quality links mean popularity, trust, authority, and higher rankings.  

Note that I said, high-quality. That’s because backlinks from low-quality sites – untrustworthy or those irrelevant to your industry - can set your SEO efforts back.

The most blatant spam links could even knock your site out of the index (perhaps with little chance of ever getting back).

The thing is, toxic links happen. It’s not always because of your link building strategy, yet they do happen. The only way to avoid any problems because of them is to spot and eradicate them early.

In this post, I’ll show you how to do this. You’ll discover how to perform link profile analysis to identify poor quality links and maintain a clean link profile. I’ll also share what to do to build a strong brand with good quality backlinks.

But first, let's begin with the basics.

 

What is a Link Profile?

The term, link profile, refers to all the external links pointing to a site. But aside from the number of backlinks, the link profile also defines such link characteristics as:

  • the types of links pointing to your site,
  • anchor texts they use,
  • the quality of referring domains,
  • topical relevance and more. 

Why Do We Pay Attention to Those Factors?

For one, because Google and other search engines use them to determine both your site's and your content's authority, and rank them in SERPs. 

A healthy link profile will increase your chances of ranking well for whatever phrases you target.

Too many suspicious links in your profile, however, might hinder your SEO campaign or even result in a manual penalty. 

What Does a Healthy Link Profile Look Like?

The answer will depend on the website, of course. In general, however, we consider a link profile healthy if:

  • It has many organically acquired, high-authority backlinks with relevant, non-spammy anchor text,
  • Most of the links come from sites with topical relevance to the linked site.
  • It contains not too many site-wide links from low-quality domains, and not many low-quality links in general.
  • It contains different types of links.

As mentioned, the actual breakdown of high-quality vs. low-quality links differs between sites. There is no golden measure to follow. 

For that reason, I always recommend the common sense approach. You will get some spammy links. As you'll see shortly, they are unavoidable. However, if the number of them gets suspiciously high, I recommend corrective action - disavowing them. 

Another factor that affects the health of your link profile is the link quantity. Having many (good quality) links pointing to your site helps increase rankings. But if your domain has too many backlinks, or have acquired them too quickly, your link profile might raise suspicions and result in a penalty. 

How Do Toxic Links Happen?

As part of our work at the Professional Services team, we regularly assist clients with link analysis. And if truth be told, we find low-quality, sometimes even toxic links on almost every site we review.

But this is only natural. With so much activity on the Internet, a website is bound to have at least some weak backlinks in its link profile. Here are some reasons why:

  • Many websites use automated scripts to scrape and republish other people’s content. And to look more trustworthy, some reference and link to the source to the page. This, naturally, results in a backlink, albeit far from a good quality one.
  • A company might have been using low-quality link building strategies in the past. After all, it was common for websites to acquire links through content farms, guest posting on low-quality sites or link exchanges. Today, however, those links are nothing but toxic. That said, they might still exist in their link profile.
  • Human actions could play a part here too. A company’s SEO could have built some weak links in the past. Similarly, a 3rd party link building firm the organization had hired, might have taken some shortcuts when delivering the promised link quota. They might have purchased links from blog networks or used automated commenting software, for example.

For the most part, however, having a small number of low-quality links would have little or no effect on your SEO efforts.

The problem starts when the ratio tilts towards toxic links or you have too many obviously spam backlinks in your link profile.

So, let’s see how to find out whether that’s the case.

 

Link Profile Analysis - Identifying Toxic Links

Link profile analysis is the process of evaluating your backlink profile to identify potentially problematic reference, and eliminate them before they hinder your SEO efforts. 

From experience, I suggest that you conduct one of the following methods at least once every six months. This way, you can clean up your profile before the number of toxic links would aggravate.

Method #1. Review Referring Domains by Trust Flow

Trust Flow, a metric developed by Majestic, predicts how trustworthy a page is based on its quality. It’s the clearest indicator of the overall quality of a linking source.

Because Trust Flow relates to an entire domain, it allows establishing how reputable is a source by looking at just a single backlink from it.

In seoClarity, you can sort linking domains by Trust Flow, giving you immediate access to potentially low-quality sites.

But let me be clear here. A low Trust Flow should not be the only indicator. Some URLs would look suspicious right away. Overuse of keywords in the domain names and other factors might give them away.  

Some links, however, might come from new domains that didn’t have the time to build up their Trust Flow. With those, do a quick manual check to validate whether they look trustworthy or not.

Method #2. Verify Links from Non-Local TLDs

Many low-quality links come from specific, non-local TLDs like .cn, .ru, .ro, among others.

Note, I’m not suggesting that all domains from those regions would be spam. However, it’s worth filtering your link profile by regions. And then, reviewing those TLDs to ensure these sites are good backlinking partners.

Method #3. Evaluating the Anchor Text

Anchor text might suggest bad links too. Review the most common anchor texts in the link profile to identify potential toxic links this way too.

Method #4. Review Topical Relevance

Toxic links rarely come from domains with topical relevance. That's because, most of the time, those sites have no specific topic they cover. Instead, they post (or re-post) random content from the web to increase the page count and make the site look alive. 

The majority of Nike's links come from sites relating to sports, which only makes sense, given the company's products.

Removing Toxic Links

There’s only one thing you can do to get rid of low-quality links from your profile – disavow them.

Disavowing links allows you to ask Google not to consider certain backlinks when analyzing your profile. And you do it by submitting a disavow list in the Search Console.

But here’s a mistake I see companies doing over and over again. They create a new disavow file with every link analysis they’ve conducted. Each time you upload a disavow file to Google Search Console, the file replaces your previous file. To help ensure all unwanted are disavowed permanently it is recommended to append the file each time. 

Instead, you should append the original disavow file with new toxic backlinks you might have discovered.

BONUS: Building a Brand with High-Quality Links

The lure of building low-quality backlinks is that you can create them relatively fast. Guest posting-only blogs don’t care about content’s quality. You can submit almost anything and still get a link. Using blog networks takes as much as signing up and filling in a profile. Buying links is relatively quick too. True, it costs you money. But you get those links fast too. 

The alternative, acquiring high-quality requires work and effort. Take outreach, for example. It can take a tremendous amount of resources and time to create a strategy, from content assets to managing the outreach campaign. And even then, you can never be sure of the result.

But in spite of this, I always advocate the long-term approach. However, there are some strategies that can generate great links with slightly less effort than outreach.

#1. Press releases

For many brands, a press release seems a thing of the past. With the rise of digital PR, public relations practitioners have shifted their focus to building online visibility. And for that, they use content, social media, and other channels instead.

But press releases still have their use, even for SEO. Distributing them through services like PR Newswire or Marketwired can land mentions in many serious publications, along with links, if you’ve included them in the press release, of course.

#2. Building profile links

Most high-quality links today are content-based. However, a few other opportunities remain to build backlinks without having to create original content.

Take social media for example. Most networks allow users to create profiles. Many have dedicated options for brands to set up pages and company profiles. And all of them permit referencing the person’s or brand’s sites. Granted, some of those links are no-follow. However, I believe that Google considers them, at least to some degree.

Local store or business directories are another examples. Again, some of those links are no-follow. But given the ease of creating them (and additional benefits of having such profiles), they’re well worth it.

#3. Embedding Link Building Across the Organization

SEO is no longer a siloed discipline. Countless other teams partake in a website’s search success. And it’s no different with link building.

For example, the PR team, with its focus on expanding a company’s online visibility through content distribution could help build many high-quality links.

And all they really need for that is a list of URLs and anchor texts to use.

#4. Using Sponsorships as an Opportunity to Gain Links

Sponsorships offer an opportunity to raise brand awareness and align a brand with a right cause. Be it supporting sporting venues, community initiative or school teams; a company can use it to position itself as a socially responsible organization.

But also, to build high-quality links.

Most organizations list donors and sponsors on their sites. And even if they don’t link to their websites, there are other opportunities to gain backlinks from them:

A sponsorship announcement on the blog. The organization could simply post a quick article introducing your company as a new sponsor. And link to your site as well.

Press releases. Similarly, it could distribute a press release about it (and publish it on their site too.) This, in fact, could result in more than a single link, should the media pick it up.

#5. Interviewing the CEO

CEOs (and other C-suite executives) are often an overlooked link building asset. But think about it, they are people of high status in the organizations. They hold key strategic positions and are responsible for directing the company’s growth.

Most likely, they hold insights many others would love to gain.

And here’s the opportunity. Book them on podcast interviews. You can use services like X that will organize everything for you. Your CEO will only have to show up.

But since most podcasts publish show notes, containing resources and interviewee bios, you can gain high-quality links this way (and raise the brand awareness in the process.)

Conclusion

In SEO, links mean popularity, authority, and trust. Unfortunately, toxic backlinks can hinder all your SEO efforts significantly.

That’s why, it’s crucial that you conduct link profile analysis at least once every six months, disavow low-quality links, and focus on building references from more trustworthy sites.
