How to add external website link into post author name of divi theme

METHOD 2 (Recommended): Filter Author Link (No Child Theme)

This forces WordPress to always replace the author link with an external URL.

<?php
add_filter(‘author_link’, function ($link, $author_id) {
return ‘https://yourwebsite.com’; // external link
}, 10, 2);

✔ Every author name now links to your external website

Use Author Profile → Website Field

No code, Divi-safe

Divi automatically links the author name to the author website URL if it exists.

Go to WordPress Dashboard → Users → All Users
Click the Author
In Contact Info → Website, paste the external URL
example: https://yourcompany.com
Update Profile

✔ Done.
Now the author name in Divi blog posts links to that external site.
