A cache is the reason why web pages load so quickly when a user hits the Back button in their web browser, since the page is not being redownloaded off of the Internet. Google is unusual among search engines in that it allows Internet users to view the cached version of web pages in its index. Simply click on the word "Cache" next to the search result of interest and you will be taken to a copy of the page as Googlebot discovered and indexed it.This feature of Google makes it easy to spot cloaking...

Many content management systems are configured with errors which cause duplicate or exceptionally similar content to get indexed under multiple URLs. Many webmasters use inconsistent link structures throughout their site that cause the exact same content to get indexed under multiple URLs. The canonical version of any URL is the single most authoritative version indexed by major search engines. Search engines typically use PageRank or a similar measure to determine which version of a URL is the canonical URL. Webmasters should use consistent linking structures throughout their sites to ensure that they funnel the maximum amount of PageRank at the URLs they want indexed. When linking to the root level of a site or a folder index it is best to end the link location at a / instead of placing the index.html or default.asp filename in the URL. Examples of URLs which may contain the same information in spite of being at different web addresses: http://www.seobook.com/ http://www.seobook.com/index.shtml http://seobook.com/ http://seobook.com/index.shtml http://www.seobook.com/?tracking-code Catalog (see Index)

A listing used by pay per click search engines to monetize long tail terms that are not yet targeted by marketers. This technique may be valuable if you have very competitive key words, but is not ideal since most major search engines have editorial guidelines that prevent bulk untargeted advertising, and most of the places that allow catch all listings have low traffic quality. Catch all listings may be an attractive idea on theme specific search engines and directories though, as they are already pre qualified clicks.

Categorization is the process of organizing pieces of information into topical categories. Usually, these are hierarchical trees, with the most general topics at the top and the most specific at the bottom. A department store might have: Products, Shoes, Women, Cross-Trainers, while a gardening site might have a category: Plants, Flowers, California Natives, Poppies. In either case, a searcher can understand more about the content of the page when they know the category. Some categorization products will attempt to classify data automatically, while others assist human catalogers A search engine may apply categorization of the documents in the index based on similarities (typically based on a training set), matching rules or programmatic rules.
