1. What is a dead link?

Dead links refer to links to a page that cannot be opened or have been deleted due to various reasons. They could be caused by a site refactoring, a page being deleted, or due to some kind of bug. Dead links have a negative impact on both user experience and search engine optimization (SEO). For users, if they click on a link that cannot be opened, it may cause them to leave the site, thus reducing conversion rates. For search engines, dead links may cause search engines to reduce their trust in the website, thus affecting the website's ranking.

2. How to check dead links on a website?

1. Use online link tools: There are many online dead link detection tools, such as LinkDeath, LinkDefender and Xenu. These tools can automatically detect dead links in your website. You only need to enter your website domain name, and the tool will scan your website and list all dead links. Some tools can also provide additional information about dead links, such as the number and location of dead links.
2. Use webmaster tools: Most webmaster tools, such as Google's webmaster tools, Baidu's webmaster tools, etc., provide the function of dead link detection. You can add your site to Webmaster Tools and use this feature to check if your site has dead links.
3. Use robots.txt file: Create a robots.txt file in the root directory of your website and add the following code in it: Disallow: /error/. Then add your website to all search engines in the webmaster tools. Once your site is crawled, search engines will discover this robots.txt file and stop crawling your error pages. In this way, you can see information about your website's error pages in the search engine's webmaster tools, including which pages are dead links.
4. Use the browser developer tools: Right-click on any web page and select "Inspect Element", or use the shortcut key (usually F12 or Ctrl Shift I) to open the developer tools. Under the "Network" tab, you can see all HTTP requests. If a request returns a 404 error, then the link corresponding to this request is a dead link.

3. How to deal with dead links?

1. Repair dead links: Dead links that can be repaired should be repaired immediately. This may involve updating links to better match the new site structure, or recreating pages that have been removed.
2. Add error page: For dead links that cannot be repaired, you can add a custom error page to replace the default error page. This page can display a friendly error message to the user and provide some solutions, such as accessing related content through other links, or contacting customer service.
3. Use 301 redirect: If you have a dead link that is frequently visited, you can use 301 redirect to redirect the user to another related page. This will not only reduce user frustration, but also transfer users' trust in the website to new pages.
4. Regular check: Even if your website does not have dead links now, there is no guarantee that there will not be any in the future. Therefore, it is very necessary to check dead links regularly. You can set up a regular task to do this automatically, or use an online dead link detection tool to perform regular checks.
