I completely agree with that comment! ablife you can't advise somebody that inner pages aren't useful. They are! And the best you can do is getting a large amount of backlinks for all your inner pages, then makings internal links to distribute the link juice where you want.
some directory sites allows homepage link, while some limits deep link submissions up to 3 different landing pages only. It'll be impossible to send all of your site's landing page to a single directory
