Several of the most common search engines will also require you to find a relevant category for your website, which can be very specific to the directory organization of that search engine. And then, there are many specific rules you must be aware of and read about before attempting to submit your website for registration. In the end, you will know when and how your website was requested for inclusion. Sorry for the screaming. The other aspect that controls the availability of a website is rank order.
Search engines take time to register a new website.
The aggravation for webmasters is that it may take several re-submissions before a search engine decides to visit and spider your website. The problem here is that the search engine personnel out there are overwhelmed by the growth of the Internet and cannot keep up. This is the unfortunate control that InterNIC has over the Internet. If you have a clearly foreign address like .ca or .uk or whatever, you may have a hard time getting listed. There is also a fine line between spamming and providing an honest set of site keywords.
