Kaustubh, thanks for the great addition...
The major thing you must keep in mind is the "natural way" of adding links. We know that Google doesn't think that cheap-$5-directory-submission-into-1000-directories
just for links is a good and natural way of growing your links - that's why you must show Google how *organic* you're

For a new site start with, say, 10-30 a day, and then keep adding the same amount every day, or increase them slowly (since your site grows, it should get more and more links.) But if you submit your site into, say, 5000 directories overnight, and then forget about this for half a year, and then one day you decide to repeate the procedure once again - this doen't look natural anyway, and you might get into trouble then...
