Promotion is far more than just submitting a web site's URL to a bunch of search engines.
Promotion starts while your site is designed , involves selecting the best keywords and optimizing your site to satisfy the ranking criteria of the search engines, intelligently submitting your URL where it will acheive for maximum exposure, then keeping tabs on the competition, following up on submissions and determining current site rankings, and reacting to ranking changes effectively. With the volume of web sites growing every day, search engines are constantly shifting a site's ranking. It is not easy to keep a site in the top 10 for a competitive search topic for a long time. Sometimes sites just drop off a search engine's database. Your competitors are also looking to get one of those top rankings and may push you down the list.
