From your dashboard, go to Page >> Add New
then make the new page have just the two links. Then go to Settings >> Reading
, select “A static page”, and then choose the page you just created from the drop down.
However, if that page isn’t blank enough because it incorporates elements of your theme, you’ll need to create a new template file. You can access your site via ftp, navigate to yoursite.com/wp-content/themes/yourcurrenttheme
and drag in a text document you’ve created on your computer called whatever.php, with the content:
<?php
/*
Template Name: Whatever the name of this is
*/ ?>
Go to this <a href="https://www.cnn.com">external site</a> or <a href="mygreatsite.com">Proceed</a>
You can also more easily create a custom theme template file like this with the FTP-Free Theme File Creator Plugin I built.
Once you’ve done that, create a new page, and before you publish it, look over on the right side where you’ll see “Page Attributes” which has a “Template” dropdown. You’ll see the file you created there. Choose it and publish.
