There just aren't that many. Some of the smaller search engines generate revenue by selling your email address. Even the large search engines sometimes contact you with special offers and sales pitches. Avoid this problem by using an alternate email address when you use automated submission tools. As you take steps to avoid spam in your inbox, avoid spamming the search engines.
Some webmasters think they can get ahead by submitting their site as often as several times per day.
Actually, this practice just gets them kicked out entirely. Until you're listed, submit your site once a week - but no more often. A Listing Is Only The First Step Even if you've successfully gotten your site listed in all the major search engines and directories, you can't relax. Your next step is to move your site to the top of the rankings because the vast majority of users don't look past the first few pages of results.
