What is Black Hat Link Building?
Black hat link building refers to unethical and manipulative practices aimed at artificially inflating a website’s search engine rankings by acquiring backlinks in ways that violate search engine guidelines. These tactics focus on exploiting loopholes in algorithms rather than creating genuine, high-quality content or user value.
Believe it or not, these tricks were once a go-to strategy with little to no consequences. But today? While they might deliver quick wins, black hat tactics are a huge gamble. The risks include severe penalties—like being completely removed from search results.
If your SaaS SEO agency or you are dabbling in these methods, know this: it’s a dangerous game to play that could eventually affect your SaaS growth.
Common Black Hat Link Building Tactics
1. Private Blog Networks (PBNs)
PBNs are networks of websites created purely to generate backlinks to a target site. These sites usually have little to no valuable content and exist solely to manipulate rankings.
For example, a business might create multiple low-quality blogs that all link back to its main site. While this might give a temporary boost in rankings, Google’s algorithms are sharp enough to catch on and penalize the sites involved.
2. Link Farms
Link farms are groups of websites that excessively link to each other to artificially inflate backlink counts. They focus on quantity over quality, often connecting irrelevant or unrelated sites.
A typical example? Participating in a directory that automatically links your site to hundreds of random pages. This screams manipulation to search engines.
3. Buying Links
Paying for backlinks is another popular (and risky) tactic. While it might feel like an easy shortcut, search engines explicitly ban buying links because it skews natural ranking signals.
That said, not all link buying is created equal. It depends on the quality of the website you’re getting links from and other factors. So, it’s not always black and white.
4. Comment Spam
This used to be the go-to trick for some SEOs. They’d leave generic comments on blog posts, forums, and other high-ranking pages with a link back to their site.
Thankfully, this practice has mostly fizzled out because, let’s be honest, anyone doing this today is just wasting their time.
5. Hacking and Injecting Links
Some black hat SEOs go as far as hacking into websites to sneak hidden links to their target pages. This not only breaks ethical guidelines but also violates cybersecurity laws.
Seriously though, is all that stress really worth it? Probably not.
Why Avoid Black Hat Link Building?
1. Search Engine Penalties
Search engines like Google actively identify and penalize black hat tactics. Penalties range from ranking drops to complete removal from search results.
The classic J.C. Penney’s 2011 penalty serve is a perfect cautionary tale. The retailer was found using spammy backlinks and saw its rankings plummet after Google’s intervention. The brand faced not just SEO setbacks but public backlash as well.
Sure, that was over a decade ago, but you’d be surprised how many websites still use shady tactics today and end up getting hit.
2. Reputational Damage
Being associated with unethical practices can harm your brand’s reputation, making it harder to rebuild trust with users, partners, and customers.
Even BMW wasn’t immune. They faced a temporary Google penalty for using doorway pages to manipulate search results—a known black hat tactic. While it’s unclear if it was intentional, the damage to their search reputation at the time was undeniable, even though they eventually recovered.
3. Wasted Resources
Investing time and money into black hat strategies can lead to wasted efforts once penalties are applied. Businesses often spend more time recovering from penalties than they would have spent building a legitimate link strategy.
4. Legal Consequences
Some black hat methods, like hacking and link injection, violate cybersecurity laws, exposing businesses to legal action in addition to search engine penalties.
How to Spot and Handle Black Hat Links on Your Website
1. Spotting Black Hat Links
Catching bad backlinks early can save your website from Google penalties. The easiest way to do this is by using an SEO tool. Google Search Console is free and does a solid job, but you can also try paid tools like Ahrefs, SEMrush, or Screaming Frog for more in-depth insights into your backlink profile.
So, what should you look for? Here are the common red flags:
- Sudden spikes in backlinks: A rapid jump in links from unfamiliar sources is often suspicious.
- Low domain authority links: Backlinks from spammy or irrelevant websites can indicate manipulation.
- Over-optimized anchor texts: Too many backlinks using the same keyword-heavy anchor text? That’s a potential black hat tactic.
- Irrelevant anchor texts: Generic phrases like “Click Here” or unrelated keywords often point to spammy sources.
- Irrelevant domains: Links from sites completely unrelated to your niche are usually harmful.
- Unnatural link placement: Links hidden in footers, sidebars, or even within the code are likely manipulative.
So, what do you do if you’re finding loads of black hat links? Let’s cover that next.
2. Handling Black Hat Links
Some SEOs might tell you to immediately disavow spammy links, but that shouldn’t be your first move. Instead, start by contacting the source.
Reach out to the webmasters of the spammy sites and politely ask them to remove the harmful links. Be clear—provide the specific URLs and anchor texts to make it easy for them to act.
If they don’t respond or refuse to remove the links, you may then consider disavowing. But here’s the thing: Google is pretty good at figuring out which links to trust and usually doesn’t penalize your site for spammy ones. Disavowing should only come into play if:
- You’ve accumulated a large number of spammy links.
- The links have caused (or might cause) a manual action.
Here's how to disavow black hat links.
- Compile a list of the harmful links in a .txt file.
- Use Google’s Disavow Tool to submit the file. The tool provides all the guidance you’ll need to get it done right.
3. Preventing Black Hat Links
The best way to avoid black hat links? Don’t use them—simple as that (well, mostly). But sometimes, they sneak in. Maybe it’s from a negative SEO attack or an agency using shady tactics. Either way, you’ve got to stay alert to avoid trouble. Here’s how:
- Monitor Regularly: Schedule regular audits of your backlink profile to spot issues early. Tools like Ahrefs can send alerts for new or lost links, keeping you in the loop.
- Invest in Website Security: Hacking and malware can add hidden links to your site. Stay protected by keeping your CMS updated, using strong passwords, and adding security tools like Sucuri or Wordfence.
- Build a Strong Link Profile: Focus on earning high-quality, relevant backlinks. A strong link profile helps search engines overlook any harmful ones that might slip through the cracks.
