12. Is it necessary to pay search engines for listing?
Not anymore. Yahoo directories, for example, accept paid submissions. But is it necessary to pay? No. It may speed up indexing, but eventually Yahoo will index your site regardless. Why? Because it does not want to have access to less information than Google. The leader in search engine technology, Google, has as its mission statement, to "organize the world's information and make it universally accessible and useful." It is for this reason that money for paid placement goes to absolute waste in the long run. Let the crawlers find your website through quality inbound links that we help you create during your search engine optimization process. Never use a link-farm or company that uses bad SEO practices to increase your traffic flow.
The factors that contribute to a website's successful ranking include:
1. Having quality content on your website.
2. Building proper SEO into the code of your website.
3. Establishing link popularity using marketing and advertising campaigns.
