To be a viable link within our directory it must be indexable by a search engine.
There needs to be a direct link from your homepage to your directory where our
link reside on your server.

From your homepage we should be able to click a link possibly called links that
would goto your sites directory page. Once we arrive at your directory page that
reside on your server we should be able to find the link to our site.

Any system that has a third party link back system ie linkback.com/dir/034, then
linkback.com/dir/035, linkback.com/dir/036 will be deleted.

This is how we want it;

yoursite.com has a link on the home page to yoursite.com/directory , this is
where your links reside. Inside that directory is our link. You see everything
is on your site and is indexable by a search engine. Some one can actually
find our link from your homepage.

Our system will check this and delete all error links but if you do it right the
link will remain within our directory.
