Internet search engines, such as Google, Alta Vista and MSN, drive the delivery of information on the Internet. Recent estimates indicate that up to 85% of Internet users rely on the major search engines for locating information on goods and services.
However, these search engines each have their own protocol as to how sites are indexed into their database and how submissions should be handled.
In fact, search engines are constantly changing their protocols to ensure pages listed in their indexes are relevant and accurate, based on the search phrase entered. It is very possible for your site to be deemed as "spamming" with improper submissions or inappropriate techniques. The results can be lowered rankings, page removal or in some cases, being banned from the search engine. That's why it's so important to understand, or know someone who does, the rules and protocol of each major search engine.
Paid Submissions: many search engines will allow you to pay a submission fee to be indexed quickly into their database. This strategy can be advantageous, but it does not guarantee your site will achieve a high ranking listing on the first or second pages. Without search engine optimization of your pages, your dollars spent will not return the results you desire.
