Link Rot: What It is and How to Deal with It

link rot

Even if you don’t have any broken links on your website today, the longer your content exists, the more likely this problem becomes. That’s because your hyperlinks are aging. Each new day brings an increasing risk that content you’re linking out to will disappear.

Fortunately, there are steps you can take to identify and fix any dead links you may have. Plus, by being proactive, you can minimize link rot on your own website. Maintaining the integrity of your links in this way should keep your readers happy and support your search engine optimization (SEO) efforts.

In this article, we’ll explain what link rot is and how it happens. Then we’ll discuss some ways you can find and fix link rot on your website, and prevent this problem from occurring in the future. Let’s get started!

What Link Rot Is

Link rot is the decay over time of hyperlinks throughout the internet. In other words, it refers to the accumulation of links that lead to missing or deleted content.

Your blog content probably links to pages within your own site and on other websites. The internet is interwoven with these links. However, what happens when third-party websites cease to exist or maintain their content?

You’ve probably encountered a 404 error before:

Google serves a 404 page error when a link it broken.

This means that the content you’re looking for is no longer on the server. The link you clicked on led you to a dead end. This problem happens more than you might expect. About 30% of shared social media links are dead within two years.

What's more, one Harvard study of law journals from 1999 to 2011 found that over 70% of hyperlinks didn’t link to the information in the original citation. Incredibly, 50% of hyperlinks in US Supreme Court opinions did not link to the originally cited information.

Link rot happens naturally over time. Some common reasons for it include:

  • Pages get moved, renamed, or deleted during normal website maintenance and upkeep.
  • Websites cease to exist because their owners start other businesses, don’t have funds to maintain the sites, or simply lose interest.
  • Censored content is removed from the internet by governments, institutions, or other controlling entities.
  • Hackers corrupt content or redirect URLs to other places.

Whether it happens intentionally or unintentionally, link rot is causing the internet to atrophy. There are initiatives underway, such as the Wayback Machine, to help preserve information published online. However, you can also play an active role in fighting link rot.

How to Find and Fix Link Rot on Your Website (In 3 Steps)

Link rot can affect your website in two different ways – through external content that you link out to, and internal content that you (and others) link to. Occasionally conducting an audit of your content will help you keep your content reliable. Here’s how to go about it!

Step 1: Identify Broken Links on Your Site

The first step is to determine if you have any dead links lurking on your website. We’ll show you how to do this with two different tools.

Using Google Search Console to Identify Your Internal 404 Errors

Google Search Console can help you identify any internal links that flag 404 errors. To view this information, log into your account. In the left sidebar menu, select Coverage:

Google Search Console identifies any 404 error caused by broken links on your website. Use the Coverage menu to view errors.

Any 404 errors (signifying missing pages / dead links) will be identified under Errors or Excluded:

Google Search Console displays your error types.

If the details under either of these shows a “Not found (404)” error type, select the 404 error to see the broken links:

Google Search Console shows you every URL within your website that has a 404 error.

If you prefer, you can export the list of broken links to a spreadsheet, using the Export button located in the top right.

Using a Plugin to Locate Outbound Links With Errors

To see if you have any broken links pointing to external websites, you can use a WordPress plugin such as Broken Link Checker. This tool will run a scan of your content and provide a list of broken links.

To get started, install the plugin and activate it:

WordPress plugin, Broken Links Checker, identifies your broken links so you can fix them.

Once activated, in the WordPress admin sidebar go to Tools > Broken Links. There, you'll see any broken links and where they are, so you can repair or replace them.

Step 2: Fix Internal Broken Links

Once you have a list of your broken links, you can review the individual URLs and determine which action to take for each of them. If the broken link is the result of a typo, you can simply correct the spelling in the URL.

However, most broken links are due to missing or moved content. Generally, you’ll want to use 301 redirects to fix these broken links. This will direct anyone who tries to visit each URL to similar content on your website.

Fortunately, Pretty Links makes this simple. From your WordPress dashboard, go to Pretty Links > Pretty Links and locate the URL you want to change. Select Edit Link:

Use Pretty Links plugin to handle your 301 redirects.

Then choose 301 (Permanent) under Redirection. In the Target URL field, enter where you want to redirect the link (the new URL).

Note that redirecting visitors to dissimilar pages may lead to a ‘soft 404 error', as Google doesn’t send traffic if the redirect isn’t similar to the original URL's content. This may happen if you redirect the URL of a deleted post to your home page, instead of to a post with similar content.

Step 3: Update or Remove External Broken Links

To update broken links that connect to external websites, check first for any typos in your URLs. If no such errors exist, you’ll need to replace those links with ones to new or existing content.

You might also try contacting the website with the broken link to notify them of the error. They may be unaware of the issue and choose republish the content, restoring the URL (and earning you a potential connection in the process).

How to Minimize Link Rot on Your Website

Even with helpful tools, finding and fixing broken links can take some time. It’s easier to avoid link rot in the first place. There are several precautions you can take to keep your website free of broken links:

  • Link to primary sources and reputable, stable sites.
  • Limit links to personal websites.
  • Use “pretty URLs” (search engine-friendly links).

Finally, it’s important to be aware that some third-party link shortener services may expire, go out of business, or cease to maintain the integrity of your links. Therefore, it's best to entrust your website to a reputable URL shortening tool that keeps you in control of your site's links.

Conclusion

Link rot is decaying the internet, but you can keep your website healthy and reliable by being proactive. There are several tools that can help you scan and fix broken links, and even avoid them in the first place.

To deal with broken links on your site, you'll want to:

  1. Identify broken links, using a tool like Google Search Console or Broken Link Checker.
  2. Fix internal broken links with Pretty Links.
  3. Update or remove external broken links.
