A broken link, also known as a "dead link" or "404 error," is a hyperlink that points to a webpage, file, or resource that no longer exists or is inaccessible. When clicked, it typically leads to an error page instead of the intended content. This happens for several reasons:

Common causes include:

• The target page has been deleted or moved without a proper redirect.
• The URL contains a typo or incorrect structure.
• External websites you link to have changed or removed their content.
• Permissions on the linked resource prevent public access.

For your website, broken links create a poor user experience, making your site seem unprofessional and neglected. They can also harm your search engine rankings, as search engines like Google consider a high number of broken links a negative signal about site quality and maintenance.

To manage broken links:

1. Use online tools or plugins to scan your website regularly for broken links.
2. Fix internal links by correcting the URL or setting up a proper 301 redirect to a relevant page.
3. Update or remove links to external resources that have gone dead.

Proactively checking and fixing broken links is a key part of website maintenance and helps ensure a smooth, trustworthy experience for all your visitors.
