Extension:WikiSEO

The WikiSEO extension allows you to replace, append or prepend the HTML title tag content. It also allows you to add common SEO (Search Engine Optimisation) meta elements such as "keywords" and "description".

A working job queue is absolutely required for this extension to function.

Usage
The extension can be used via the parser function or in Lua modules by using. It accepts the following named parameters in any order.

Adding dynamic values

Maintenance Script
WikiSEO provides a maintenance script to generate descriptions for specified pages. This script requires Extension:TextExtracts to be installed and active. The script will only generate descriptions for pages that don't have a  property set in the page properties table.

You can force the generation using the  flag, this will overwrite any description already present.

A list of namespace ids needs to be given in order for the script to work: php maintenance/GenerateDescription.php 0
 * 1) Run only in main namespace

php maintenance/GenerateDescription.php --force 0
 * 1) Run only in main namespace and overwrite existing descriptions

php maintenance/GenerateDescription.php --force --cleanSentence 1234
 * 1) Run in namespace 1234, overwrite descriptions and remove dangling sentences

Configuration
The following variables are in use by this extension.

Set a default image to use if no image is set on the site. If this variable is not set the site's logo will be used.

Usage:.

Array containing the metadata generator names to load.

Default:.

If you only want to change the page title and add 'description', 'keywords', 'robots' tags set

Disable setting $wgLogo as a fallback image if no image for a page was set.

Defaults to `summary_large_image` for the twitter card type.

Usage: $wgTwitterCardType = 'summary';

An array of page titles where a 'noindex' robot tag should be added. Usage: $wgWikiSeoNoindexPageTitles = [ 'Custom_Title', 'Main_Page' ];

If no description was given in the parser function, a short description from Extension:TextExtracts will be requested. A description will only be set, if the page is edited and saved. Alternatively the maintenance script  can be run from the extension folder.
