टेम्पलेट:INDEX

टेम्पलेट बिबरनलेख[देखीं] [संपादन करीं] [इतिहास देखीं] [रिफ्रेश करीं]

Usage

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 parameter

|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.

Technical details

__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

This template was originally used as a tracking mechanism for __INDEX__ usage; valid uses are now tracked by Category:Indexed pages.

History

• 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';
