Google Webmaster GuidelinesFollowing these guidelines will help Google find, index, and rank your site, which is the best way to ensure you'll be included in Google's results. Even if you choose not to implement any of these suggestions, we strongly encourage you to pay very close attention to the "Quality Guidelines," which outline some of the illicit practices that may lead to a site being removed entirely from the Google index or otherwise penalized. If a site has been penalized, it may no longer show up in results on Google.com or on any of Google's partner sites.
Bing Webmaster Center - Guidelines for IndexingThis website gives you access to all the information webmasters need about using Bing, including how MSNBot (The Bing web crawler, a program that scans websites and indexes their content, such as text, documents, images, and links, for searching.) works, guidelines for getting your website indexed successfully by Bing, and usage information on Bing Webmaster Center tools.
Open Directory Editorial GuidelinesThe ODP's goal is two fold: to create the most comprehensive and definitive directory of the Web, and to create a high quality, content rich resource that the general public considers useful and indispensable. In short, editors should select quality sites and lots of them. Remember, no site is guaranteed a listing in the Open Directory, and we depend on editors to use their own discretion. In short, we ask that editors maintain editorial integrity, keep the ODP's broader goals and mission in mind, and always employ good common sense.

Yahoo!'s Site Guidelines are designed to ensure that poor quality pages do
not degrade the user experience in any way.
Yahoo's Search Submit program strives to provide the best search experience on the Web by directing searchers to high-quality and relevant Web content in response to a search query. Unfortunately, not all web pages contain information that is valuable to a user. Some pages are created deliberately to trick the search engine into offering inappropriate, redundant or poor quality search results; this is often called "spam." Yahoo! does not want these pages in the index.
