Add Author's URL

Hi! I’m trying to add a spot into the PHP code below to that it calls on the website’s URL from their profile when they post as the href in the first a tag. I am using a child theme based off of Iconic One theme.

$author = sprintf( '<span class="author vcard"><a class="url fn n" href="%1$s" title="%2$s" rel="author">%3$s</a></span>',
		esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
		esc_attr( sprintf( __( 'View all posts by %s', 'themonic' ), get_the_author() ) ),
		get_the_author()
	);

Thank you!
