Don't submit - let the major
search engines find new pages on their own! Search engines have always
said that 90% of the pages submitted through 'add urls' is spam and
do you want to be lumped in with them? No. The vast majority of 'free'
traffic comes from just a few engines - mainly Google, the Yahoo search
engine and MSN - which send out spiders looking for new pages. So make
it easy for them to find you by ensuring there is any easy text link
from the home page, if that is possible, and the site map.
