 | This is the template sandbox page for Template:INDEX (diff). |
Usage
[edit]This template sets the __INDEX__ behavior switch, a magic word which instructs search engines to index the page. The only difference between the template and the magic word is that the template may optionally display a message.
On English Wikipedia, __INDEX__ and {{INDEX}} should only be used on User and User talk pages, where they override the default, which is not to index these pages.
Optional parameters
[edit]|visible = yes: makes the template display a line of plain text to inform editors that the page is included in search engine indexing, e.g.{{INDEX|visible = yes}}shows the message:
- This page has been added to search engine indexes.
- This page has been added to search engine indexes.
- Note: regardless of this parameter, if the template is used in an unsupported namespace, the following will be displayed instead:
- Please use {{INDEX}} only within the User and User talk: namespaces, as those are the only two in which it has an effect.
|demo = yes: makes {{INDEX}} work even if it is placed in the wrong namespace so that examples of the template can function, e.g. on this doc page –{{INDEX|visible = yes|demo = yes}}renders as:
- This page has been added to search engine indexes.
Technical details
[edit]__INDEX__ overrides $wgNamespaceRobotPolicies, but not robots.txt. It obeys the $wgExemptFromUserRobotsControl variable. On English Wikipedia, MediaWiki:Robots.txt is used in lieu of $wgArticleRobotPolicies.
On English Wikipedia, the default robot policy for the entire wiki is to index all pages. This default has been overridden in these namespaces:
- User talk is not indexed, as of September 2008
- Draft and Draft talk are not indexed, as of December 2013
- User is not indexed, as of November 2015
Additionally certain selected pages, primarily in Wikipedia and Wikipedia talk, are not indexed, as defined in MediaWiki:Robots.txt.
Mainspace, Draft and Draft talk are exempt from user control, so __INDEX__ is disabled in these namespaces; such use is not tracked (see below), and this template consequently has no effect there.
As all other namespaces are indexed by default, and robots.txt cannot be overridden by __INDEX__, the only namespaces where it overrides the default are User and User talk; however use in other namespaces is tracked.
Usage tracking
[edit]This template was originally used as a tracking mechanism for __INDEX__ usage; valid uses are now tracked by Category:Indexed pages.
History
[edit]- Added $wgNamespaceRobotPolicies to allow customisation of robot policies on a per-namespace basis (June 4, 2006)
- Added $wgContentNamespaces, which allows for articles to exist in namespaces other than the main namespace, and still be counted as valid content in the site statistics (June 12, 2006)
- Added $wgArticleRobotPolicies (May 31, 2007)
- These override the per-namespace robot policies; en.wiki uses MediaWiki:Robots.txt in lieu of this configuration setting
- The default robot policy for the entire wiki is now configurable via the $wgDefaultRobotPolicy setting (February 6, 2008)
- The default policy is to encourage indexing and following of links:
$wgDefaultRobotPolicy = 'index,follow';
