How To Detect And Repair Broken Links In WordPress

Managing broken links is an important part of website maintenance. In this tutorial, we show you how to find and fix broken links in WordPress.

How To Detect And Fix Broken Links In WordPressIf your website includes links to other websites, it’s quite probable that at some point and as more content is added, some of your links will point to pages that have been moved or deleted, or to websites that no longer exist.

These ‘broken’ links can affect your visitors’ experience, your business, your reputation, and your website’s SEO. It’s important, therefore, to have a system in place for detecting, repairing, and managing broken links on your WordPress site.

How To Detect And Repair Broken Links In WordPress

The WordPress built-in linking tool automatically checks when you add hyperlinks to your content and detects broken links. If you add a broken link (e.g. add a space in the URL), WordPress will let you know, allowing you to correct the link before publishing it to your site …

WordPress automatically detects broken links

Although WordPress can automatically detect if you type in a broken link, it can’t detect whether a correctly entered link leads to a ‘not found’ page error or a destination page that can’t be accessed (e.g. server down or website deleted).

Why You Want To Avoid Having Broken Links On Your Website

When you have no control over other websites, it’s hard to keep track of what is going on with links pointing from your site to external websites.

For example, let’s say that you run an e-commerce store, or affiliate review site promoting products from other websites …

Do you review other people's products on your site?

(Do you promote other people’s products on your site?)

In this example, when you click on the destination URL of the product shown above …

Do you know if all of your links are pointing to working pages?

(Do you know if all of your links are pointing to working pages?)

The site cannot be reached. The server could be temporarily down or the product vendor has gone out of business and their website has been permanently deleted …

This site cannot be reached!

(This website can’t be reached!)

Over time, you will probably add a number of links from your content to many external websites and this will only multiply the problem. The more external links you add from your site, the greater the likelihood of having broken links on your site, or links pointing to pages with errors or non-existent pages …

The more links you add from your site to external sites, the more 'broken' links you will probably have

(The more links you add from your site to external sites, the greater the likelihood of having ‘dead’ links) 

Can you imagine what sending people to pages or sites that don’t exist can do to your business?

Normally, there is no way to keep track of what is happening on all the websites that you link to and do not control. Dead links (i.e. ‘broken hyperlinks’) are annoying to visitors and can have a negative impact on your online business and your reputation.

Having broken links can affect your site in many ways:

  • You can frustrate and even lose customers and visitors.
  • You can lose sales if potential customers can’t find what they are looking for.
  • You can lose money if you are placing advertising banners on others sites that link to missing pages.
  • You can damage your reputation online if there are too many broken links on your site. This gives visitors the impression that you don’t maintain or care for your website, and have no regard for visitors having a positive user experience.
  • It can have a negative impact on your website’s ranking with search engines.

As more content is added to your site, the greater the chances are that some of the hyperlinks in your posts and pages will end up broken and lead visitors to pages that are no longer valid or even present in your site.

Broken links can be caused by a number of internal and external site factors, including:

  • Failure to maintain proper navigation links between the pages on your site
  • Moving content around your site
  • Renaming or deleting your web pages
  • Typing in URL addresses incorrectly when creating links
  • Replicating pages containing broken links across your site or other sites
  • Domain names expiring
  • External websites get sold, relocated, or deleted
  • External pages get removed or relocated
  • and more.

Useful Information

When a visitor tries to access a page on your site that doesn’t exist, WordPress will automatically display something called a 404 error page. Broken links will lead to an increase in “Page Not Found” errors and other unsuccessful responses.

help To learn how to customize your WordPress 404 error page, see the tutorial below:

How To Find And Repair Broken Links In WordPress

Making sure that all links on your site are working correctly is important for both your visitors and for search engines. Clicking on links that don’t work creates a bad experience for users, and search engines penalize sites that have too many broken links.

Unless you have a single-page website, however, it is almost impossible to manually check that all of the links on your site are working correctly all of the time. Fortunately, there are plugins that can do this job for you automatically.

In this tutorial, you will learn how to find and fix broken links using a free WordPress link management plugin called Broken Link Checker.
