Techopedia Explains Link Checker

There are different link checkers available: some are free and some are commercial. There are also online and offline versions available. Simple link checkers check for broken links in the Web pages of a website, whereas advanced ones also check for external links to other websites. Almost all link checkers are recursive in nature and can perform site crawling either automatically or when the user initiates it. Some link checkers come with additional features like antivirus checks, syntax checks, additional information about the links used, etc. Some link checkers also provide a browser plugin or add-on support.

One of the important benefits of using a link checker is in ensuring good usability by removing broken links and also in ensuring the search engine optimization of a Web page or a website is not affected. For website owners, it is time consuming and often impractical to individually check each external and internal link in their websites. Using a link checker, they can check the links automatically and more effectively.
