What is broken links
A broken link is a link on a webpage that leads to a non valid page or dead page. Broken links can negatively impact user experience and can also affect a website's search engine ranking.
Broken links on websites can occur for various reasons:
Moved or Deleted Content: One of the most common reasons is that the linked content has been moved or deleted. This could be due to a website redesign, content reorganization, or removal of outdated information.

Typographical Errors: Sometimes, links are broken due to simple typographical errors in the URL. For example, a missing letter, incorrect domain, or extra characters can lead to a broken link.

Expired Content: Links may also break if they point to content that was only available temporarily, such as event announcements or limited-time offers.

Server Issues: If the server hosting the linked content is down or experiencing technical difficulties, the link will be broken until the server is back online.

Changes in URL Structure: Websites may undergo changes in their URL structure, which can result in previously valid links becoming broken. This often happens during website migrations or updates to content management systems.

Access Restrictions: Content may be accessible only to specific users or under certain conditions (e.g., login requirements), leading to broken links for unauthorized users.

External Factors: External factors like changes in third-party services (e.g., APIs, embedded content) or alterations in the website's environment (e.g., changes in protocols) can also cause links to break.

Link Rot: Over time, websites may experience link rot, where linked content becomes unavailable due to factors like domain expiration, content removal, or changes in website ownership.
To prevent broken links, website owners should regularly check their websites for broken links using tools like link validators and perform maintenance to update or remove broken links as needed. Additionally, implementing proper redirects and maintaining consistent URL structures can help mitigate the risk of broken links in the future
