Many once-small search engines in China and India are getting more and more popular after 2007. For example: Baidu.com(Nasdaq:BIDU) was not well known at the beginning. It is now the most popular search engine in China, while Google is in second place. Without submitting to these search engines via search engine submission software, you may miss millions of visitors who might come to your website via these search engines. The second benefit is that, some search engine submission software not only submit your web site to search engines, but also add links to your web site from their own link pages submitted. This is very helpful in increasing your web site's ranking, because external links are one of the most important factors to a web site's ranking.
