Checking external links is the process of verifying whether links on a web page are still active and pointing to the intended destination. These links can be to other websites, files, or resources on the internet.
Checking external links is important for a number of reasons. First, it helps to ensure that your website is providing accurate and up-to-date information. If a link is broken, it can lead to a negative user experience and make it difficult for visitors to find the information they are looking for. Second, checking external links can help to improve your website’s search engine optimization (SEO). Search engines like Google use the number and quality of external links as a factor in determining a website’s ranking. By checking your external links and ensuring that they are all active, you can help to improve your website’s visibility in search results.
