Description: A link checker is an essential tool in web development used to identify broken or non-functional links on a website or application. These links can be internal, pointing to other pages within the same domain, or external, directing to different websites. The presence of broken links can negatively impact user experience, search engine optimization (SEO), and site credibility. Link checkers work by scanning the content of a webpage, following each link, and checking its status. If a link returns a 404 error (page not found) or any other error code, it is logged for review. These tools are especially useful in large-scale projects where manual link management may be unfeasible. Additionally, they are often integrated into continuous integration pipelines to automate link verification with each deployment, ensuring that content is always accessible and functional. In various online platforms, maintaining operational links is crucial for user engagement and conversion, as broken links can lead to the loss of potential customers. In summary, a link checker is an indispensable tool for ensuring the integrity and functionality of a website.
