Editing Spamdexing (section)

==Other types==

===Mirror websites===
A [[mirror website|mirror site]] is the hosting of multiple websites with conceptually similar content but using different [[Uniform Resource Locator|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, [[Adobe Flash|Flash]],  [[JavaScript]], [[Java (programming language)|Java]] or [[Server side redirect]]s. However, [[HTTP 301|301 Redirect]], or permanent redirect, is not considered as a malicious behavior.

===Cloaking===
[[Cloaking]] refers to any of several means to serve a page to the search-engine [[Web crawler|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. Google refers to these type of redirects as ''Sneaky Redirects''.<ref>{{cite web|url=https://support.google.com/webmasters/answer/2721217?hl=en|title=Sneaky redirects - Search Console Help|website=support.google.com|access-date=2015-05-14|archive-date=2015-05-18|archive-url=https://web.archive.org/web/20150518224326/https://support.google.com/webmasters/answer/2721217?hl=en|url-status=live}}</ref>
