We love links around here.
Can’t you tell?
So we don’t take too kindly to instances where external factors come into play and compromise the integrity of link building efforts.
And if there’s one thing that has the ability to turn hard-earned backlinks into mush, it’s link rot.
Link rot is the enemy of link building – a silent yet destructive force that’s continually working to undermine a website’s results.
The most troubling part about link rot is that it often goes undetected for months or years at a time, at which time it’s spread to the point of compromising entire link building campaigns.
But there are fixes and solutions for businesses, marketers, SEOs, and bloggers who are willing to get messy and address the underlying factors.
Link rot is precisely what it sounds like.
It’s the degradation of links over time.
More specifically, link rot refers to two things:
1. Disappearing Links. It’s the decay and disappearance of links over time, which leaves in-text backlinks prone to dreaded 404 “Page Not Found” errors. In these instances the page that’s linked to quite literally disappears from the internet and ceases to exist.
2. Reduction of Power. Links don’t always disappear, but sometimes there’s a gradual reduction of link power as time passes. Either the information becomes obsolete, or newer content is produced that’s seen as being more authoritative and higher in quality.
Most people are referring to the first issue – disappearing links – when they discuss link rot. As such, we’ll be discussing link rot within this context.
Every website – including yours – is under a constant process of decay.
In one sense, link rot is a direct reflection of the real world.
Just like a small amount of moisture multiplied by many months and years of time can cause an otherwise healthy piece of wood to decay into a brittle and spongy texture, time multiplied by neglect can cause a website’s link profile to lose its shape and strength.
Link rot is something that affects every single website and blog. There’s no immunity.
According to one in-depth study on the topic, 30 percent of shared links are dead and useless within 24 months – something that shocks most people. (Suddenly the internet doesn’t seem so timeless, does it?)
While the foundational pillars of the internet are firm and long-lasting, the billions of smaller components are constantly being torn down, rebuilt, replaced, and reconstructed.
Over a period of 20 years, 98.4 percent of web links experience rot.
This rot ultimately leads them completely inaccessible to future generations.
Research and data curated by Textmetrics reinforces just how prevalent link rot is. Just take a look at the following data points:
Those are alarming figures!
But if you think it’s just tiny niche blogs and poorly run websites that are facing this problem, think again.
While spammy pages and clickbait stories shared on social media are prone to rapid link rot, they aren’t the only victims.
Did you know that more than 50 percent of U.S. Supreme Court opinions contain dead links? Likewise, 70 percent of Harvard academic journals suffer from link rot.
If legal judgements and scientific research – two linchpins of modern society – are prone to the effects of link rot, then it’s reasonable to assume that every website, blog, and online resource is as well.
Now that we have a clear understanding of precisely what link rot is, let’s dig in and analyze why links rot in the first place.
Some common causes of link rot include:
At the end of the day, most link rot is the direct result of neglect – either intentional (closing down a website) or unintentional (not following proper protocol when making changes to a page).
Link rot might be normal, but it’s not acceptable.
Some link rot is inevitable, but the more rampant it is, the more detrimental it becomes.
Link rot is troublesome for numerous reasons, including:
Most people don’t understand how serious link rot truly is.
By grasping the deep-rooted impact of link rot, you’re ahead of the game.
The next step is to do something about it.
Link rot is something that’s going to occur “naturally” over time.
However, this doesn’t mean you have to put up with it.
There are plenty of ways to proactively strike back – and that’s what we’re going to discuss in the rest of this article.
Take a look at some specific ways you can fix and/or avoid link rot moving forward:
Take the time to carefully review your site to find dead links.
This can be done fairly easily and effortlessly with a link crawler like Screaming Frog SEO Spider, Moz Pro, or DeepCrawl. (You can also check individual URLs and pages with a Chrome plugin like Check My Links.)
When crawling your site, you’re looking for any page that gives you a 404 code.
Take each of these pages and update the link so that it points to a new/live page with relevant content. If no such page exists, you can remove the link altogether.
For links that you move, create a 301 redirect pointing to the new destination. This ensures the link actually counts as a link.
The key is to make sure the 301 redirect is going to a page that is considered equal to the page that was previously linked to. (You can’t just 301 redirect everything to your homepage. This has no positive impact on PageRank.)
When linking out, be judicious with the links you integrate into your content.
Quality is far more important than quantity.
Every additional link you integrate into your content creates an opportunity for another broken link.
Only include essential links from reputable websites in your content. This significantly lessens the chances that you’ll have to spend a lot of time and energy warding off link rot later down the road.
Using only essential links also helps the user experience of your site.
Excessive linking is distracting and can lead your website visitors to feel overwhelmed. With each additional link, you devalue the rest.
By using links only when they’re necessary and essential, your readers are more likely to take these links seriously and see them as important and worthy of attention.
Link rot is very common when there’s a PDF involved.
While there’s nothing inherently wrong with linking to PDFs, you should know that they’re much more prone to rot over time.
If you link to a lot of PDFs, you’ll end up with an abnormally large link rot percentage in two or three years.
The good news is that many pieces of content are available in both a PDF and web page format. If given the option, you should always link back to the web page.
Web pages, as fickle as they can be, tend to be more stable than PDFs (which are often renamed and moved around).
Long URLs with dozens of characters and various codes/strings at the end are just asking for rot.
The more information a URL has attached to it, the more chances there are for something to mess up in the future.
Alway be on the lookout for the most compact form of a URL. The cleaner the URL is – meaning no unnecessary information after the core – the less likely it is to have issues.
Cleaning up links is usually a fairly easy process – and one that you can train your eyes and tune your mind to.
For example, whenever there’s a “?” in a URL, the characters after it are usually tracking codes and other non-essential information. Try removing this portion of the URL and see if it still works.
Link building is all about generating high quality backlinks from authoritative websites – and it takes a lot of work!
Losing an earned backlink is frustrating and detrimental to your website’s SEO.
Thus it’s also important to take care of your own website links and URLs.
Using the same principles as we’ve discussed in the preceding techniques, you can lessen the chances of having your own links rot.
Here are a few tips:
Another website’s link rot can be your gain.
That’s right, link rot can actually be used as a method for building up backlinks and enhancing your own website’s link profile.
The concept is known as “broken link building.”
We go into the entire process of broken link building in this in-depth resource.
However, we’ll provide a quick recap here.
Broken link building is essentially the process of identifying broken or dead links (link rot) on other websites and blogs.
Once you find these broken links, you create your own fresh content to replace these links.
Then you reach out to the individual or company in charge of the web page and let them know that they have a broken link (which you can replace with content that’s twice as good).
That’s the simple gist of broken link building. In actuality, it’s a much more time-consuming and complex process.
The key is to establish the right processes, automate the repetitive aspects, and outsource the elements that suck up too much of your time.
By putting broken link building on autopilot, you’re able to pick up new backlinks on a consistent basis without much trouble. (You can also rest easy at night knowing you’re helping to reverse the effects of link rot, which erode the internet from the inside out!)
There’s nothing simple or easy about link building.
But it’s an integral element of being successful in today’s web climate.
Link rot often stands in the way of this success.
By understanding what link rot is and how it can be overcome, you can lessen its impact on your content, SEO, and marketing goals.
