The use of automatic Submit tools for the major search engines and directories may not be desirable. If you submit to some search engines incorrectly your pages could actually be deleted permanently from their index or directory. At the same time, you may find manual submissions too time consuming.
Experts have suggested that you use software that submits pages as if you were doing it by hand. TopDog, Web Position Gold and Submit Wolf Pro are good choices. Some others are: CommandoPro Submission Software, Add Web Site Promoter, VSE Be Found (Mac), Submission 2000.
Be very careful in selecting the company or service that you hire for search engine optimization, if you do not wish to do it yourself. Beware of those who promise top engine rankings through the use of Meta tags or by building doorway pages or using link farms or cloaked pages (submitting pages that are different from the actual live pages). If the firm tells you that you need to improve content, position keywords carefully, and seek quality reciprocal links, perhaps that is an indication of a good firm to work with.
