Broken links are easy to ignore because they rarely break a whole website at once. A visitor clicks a page, product, download or old blog reference and lands on an error. One bad link may not feel urgent, but lots of them quietly damage trust.
They can also make a site harder for search engines to crawl and understand. Keeping links tidy is a simple maintenance task with a useful payoff.
Why broken links happen
Links break for ordinary reasons. You might delete an old page, change a URL, rename a product, remove a downloadable file or link to an external site that later disappears.
The older and larger the website, the more likely broken links become. Blogs are especially prone to it because they often link to older sources, tools, events and pages that move over time.
Check your own site first
Internal broken links are usually the most important to fix because they are under your control. These are links from one page of your site to another page that no longer exists.
A good first step is to crawl the website with a link-checking tool. There are desktop tools, online crawlers and WordPress plugins that can report broken internal links, missing images and redirects.
If you use a WordPress plugin for this, avoid leaving heavy scans running constantly on a live site. For larger websites, a dedicated external crawler is often cleaner.
Decide whether to update, redirect or remove
Not every broken link needs the same fix.
If the destination page still exists under a different URL, update the link. If the old URL receives traffic or has value, add a redirect to the best matching page. If the link points to something that no longer matters, remove or rewrite the sentence.
Avoid redirecting everything to the homepage. It may feel tidy, but it often creates a poor user experience. A visitor who clicked a specific guide, product or service page expects something relevant.
Check external links too
External links can break without you doing anything wrong. A supplier changes its website, a tool shuts down, a report moves or a page starts redirecting somewhere less useful.
You do not need to obsess over every external link, but it is worth reviewing important posts and service pages from time to time. If a link supports a claim, recommendation or instruction, make sure it still helps the reader.
Use helpful 404 pages
Even with good maintenance, people will still occasionally hit a missing page. A useful 404 page can keep them on the site.
Include a clear message, a search box if appropriate, links to key sections and perhaps a contact route if they cannot find what they need. The aim is to help the visitor recover, not make them feel they have reached a dead end.
Build link checks into routine maintenance
Broken links are not a one-time fix. They are part of normal website housekeeping.
For a small site, checking every few months may be enough. For a larger content-heavy site, it may be worth scheduling more regular crawls. Any time you remove pages, change URLs or restructure content, check the links afterwards.
A website does not have to be perfect to be useful, but it should feel cared for. Fixing broken links is one of those small jobs that makes the whole site feel more reliable.
