You must own the particular page or have submission rights to the page in specific.
If you order the gig extra, "provide key-word research to figure out the most ideal key words for your page"
I can help you to pick out the ideal main focus words and additional key phrases to increase directory acceptance rate and visibility.
I do NOT guarantee backlinks, nor can anyone. This is a submission, do your own research.
The process I go about is by submitting your page to numerous directories relevant to your niche'. The benefit is that you'll get some valid dofollow/nofollow links potentially to help build your pages value. This service doesn't help all niche's, but gives you initial value and exposure.
