Cannot locate specific link/string using String Translation with WPML? [closed]

You need to put your strings in translatable format.

<a href="https://wordpress.stackexchange.com/questions/90208/URL"><?php _e( 'Link', 'your-theme-text-domain'); ?></a>

Function reference: _e(), this one echoes the value, for assignment, use $my_string = __( 'String', 'text-domain' );.

Also, check the following documentation: WordPress_in_Your_Language#Introduction and WPML – Getting String Translation to Work.
