A broken link refers to a webpage that is no longer accessible, usually because the page has been deleted or the URL has been changed without proper redirection. When someone clicks on a broken link, they are typically shown an error message like “404 error” or “page cannot be found.” Broken links can have a negative impact on the user experience, as they prevent visitors from accessing the content they were seeking. Additionally, they can harm a website’s SEO performance, as search engines favor sites with functional and properly maintained links. Regularly checking for and fixing broken links is essential for maintaining website quality.
