A broken link refers to a hyperlink on a website that is no longer functional or leads to an error page. This can occur due to various reasons such as the webpage being deleted, the URL being changed, or the website being temporarily down. Broken links can negatively impact a user’s browsing experience as they are unable to access the intended information or page. They can also affect a website’s search engine ranking and credibility. It is important for website owners to regularly check for and fix broken links to ensure a smooth and seamless browsing experience for their visitors.
