Effective link development campaigns are crucial to your site's search engine visibility. Web directories generally allow Web site owners one chance to submit correctly, with few exceptions. Objective, third party link development is an ongoing process. With the crawler-based search engines, spiders should be able to find your pages without direct submission as long as the URLs exist on your Web server.
A Web site is always a work in progress. Technology and visitor preferences constantly evolve. With successful search engine optimization and careful traffic analysis, Web site owners can continually modify their sites for their visitors and maximum search engine visibility.
