New sites do not need to be "submitted" to search engines to be listed. A simple link from an established site will get the search engines to visit the new site and spider its contents. It is rarely more than a few days from the acquisition of the link to all the main search engine spiders visiting and indexing the new site.
Google found a solution to index the web pages protected by webmasters or owners. "First Click Free" means to allow Google to include your protected pages in the search results, and to provide full access for the text on that page. This way, the first visit is free for paid subscription and other protected pages and does not require a login. The free visitor can be block for the other protected pages or sections.

Google Economy identifies the concept that the value of a resource can be determined by the way that resource is linked to other resources. It is more complex than search ranking, and broader than interlinked web pages, though it draws meaning from both.
