Here’s a screenshot below showing the redirection set up from an old domain to a new domain. The “Source URL” only requires the forward-slash (/) followed by the page name. However, the “Target URL” must also include the domain and its protocol (http or https) because it’s on a different web server.
Now here’s a screenshot below showing an internal redirection setup on the same domain. Both the “Source URL” and “Target URL” only require the forward-slash (/) followed by the page name because they are located on the same web server.
Note: If you’re redirecting a web page that’s within a directory, then make sure to include the full directory path. For example, /directory/newpage.html.
If you’re comfortable editing the .htaccess file on your web server, then you can perform the redirection process without using a plugin. All you have to do is add a line of code to that file for each URL you want to redirect to a new web page.
