Other types of spamdexing
Mirror websites
A mirror site is the hosting of multiple websites with conceptually similar content but using different URLs. Some
search engines give a higher rank to results where the keyword searched for appears in the URL.URL redirection
URL redirection is the taking of the user to another page without his or her intervention, e.g., using META refresh
tags, Flash, JavaScript, Java or Server side redirects.Cloaking
Cloaking refers to any of several means to serve a page to the search-engine spider that is different from that seen by
human users. It can be an attempt to mislead search engines regarding the content on a particular web site. Cloaking,
however, can also be used to ethically increase accessibility of a site to users with disabilities or provide human users
with content that search engines aren't able to process or parse. It is also used to deliver content based on a user's
location; Google itself uses IP delivery, a form of cloaking, to deliver results. Another form of cloaking is code
swapping, i.e., optimizing a page for top ranking and then swapping another page in its place once a top ranking is
achieved.References
