One of the main reasons that you might want to redirect your page to a different URL is when you buy a different domain or merge 2 companies or websites and want all traffic to be on a single one. In this case you can use the following HTML query to redirect all visitors to a specified URL:

<meta http-equiv="Refresh" content="0; url='https://behrouz.online'" />

The above HTML code will redirect your users to https://behrouz.online after 0 seconds. If you want your users to be redirected after 5 seconds for example, you will need to change content=0 to content=5, also the value for url would be the destination where you want your users become redirected.
