Multiple domains have the added benefit of improving visibility in AltaVista, since AltaVista displays only one domain name per search result. Doorway and hallway pages allow content to be tailored to a search engine's specific requirements. AltaVista has recently cracked down on such techniques, and other search engines are expected to follow suit. With doorway and hallway pages designed and uploaded, it's time to submit to the search engines. Submit hallway pages instead of the doorway pages, unless the company absolutely can't wait until the search engines spider the doorway pages on their own.
Turnaround time varies from several days to several months, depending on the search engine.
If several months pass with no spidering by one of the search engines, resubmit. Most webmasters choose to submit to the major search engines manually, although WebPosition Gold does have a submission component that impersonates a web browser to the search engines when submitting, and displays the search engine's results page. RealNames is affiliated with search engines such as AltaVista, meta-search engines such as Go2Net's MetaCrawler, and even the popular web browsers. After pages are submitted, monitor rankings periodically over time and make changes as needed. Note the keywords people use in the search engines to reach the site.
