Read on below to learn about broken or dead links and how to fix and check broken links on any websites you operate.

What Are Broken Links?

A broken link is a hyperlink that links to a non-existent page or resource. Most of the time, these linked pages are missing because they were deleted or relocated without a redirection in the time since the link was originally added to the page. A broken link is also known as a dead link or link rot.

When a user or crawler clicks on a broken link, the server sends the status code 404 (Not Found) or 410 (Gone). That is the origin of the “404 – page not found” error you may well have seen online.

There are several types of broken links that you may encounter on your website and pages.

Broken Internal Links

A broken internal link is a link that is supposed to redirect users to another page on your website, but for some reason, it is failing to do that.

However, if you have modified your website URL, deleted the page, or had pages dropped during a page migration, you may have broken internal links on your site.

Broken links make it difficult for Google and other search engines to crawl your pages, and broken links prevent Google from moving on to the next page in the crawl.

As a result, Google may believe that your website is not optimized or is incomplete, which would harm your ranks.

Having several broken links can have a huge impact on your site’s rankings, and for your site to score well on Google, you will need all the links on your web page to work properly.

Broken External Links

An external link directs a user to a website that is not under your control, typically another site that supplements the content on your own pages. These are also known as outbound links.

When these links break, it could mean that the external site now no longer exists, has relocated, or does not have the proper redirects in place.

These types of broken links degrade the user experience and can harm your search engine authority, as links to dead sites make your website appear less authoritative and trustworthy.

Broken Backlinks

Backlinks are links to your content on other websites. They are essentially external links to your website from other sites.

When you update your content or make any other changes, such as changing URLs or deleting pages, your backlinks will no longer be able to support your website and generate authority, which might harm your status with Google and other major search engines.

Why Are Broken Links A Problem?

Broken links will harm your Google Search results but not your overall SEO. A large number of broken links on a single page may suggest that a site has been neglected or abandoned.

Google’s Search Quality Rating Guidelines also make use of broken links to establish a site’s quality, but as long as you are regularly monitoring for broken links or resolving broken links when Google tells you of a new issue identified on your site, you should be able to keep up a high-quality web presence.

The problem comes when you have too many broken links. If your web page hosts a large number of broken links, Google will mark your entire site down.

One or two is fine – link rot is a thing that happens naturally, and dead links can be impossible to avoid. The problem is when all the links on the page are broken.

Do not overlook the effect of a dead link. User experience is one of the main factors that influence SEO. When search engine algorithms are updated, it is usually because the primary purpose is to give consumers a better search and experience overall.

Although Google will recognize that there will be some broken links, actual users may not be as forgiving. This will undoubtedly harm your reputation.

Each visitor to your page will base their choice on usability, experience, load time, and content.

If there are broken links on your site and the visitor is unable to access the information they are looking for, they will go to another site that can supply them with the information they want.
