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 Optimization) meta elements such as "keywords" and "description".

Version 2.0 is not a drop-in replacement for v1.2.2 (the last version before this fork).
Version 2.3.1 fixes a bug in the generated schema.org search action url. Please update to the newest version of this extension.
Version 2.6.2 and onward requires MediaWiki 1.35.0. You can find the last version supporting =<1.34.0 on branch REL1_34.

Examples[edit]

Adding static values[edit]

{{#seo:
|title=Your page title
|title_mode=append
|keywords=these,are,your,keywords
|description=Your meta description
|image=Uploaded_file.png
|image_alt=Wiki Logo
}}

Adding dynamic values[edit]

If you need to include variables or templates you should use the parser function to ensure they are properly parsed. This allows you to use Cargo or Semantic MediaWiki, with Page Forms, for data entry, or for programmatic creation of a page title from existing variables or content... 

{{#seo:
 |title={{#if: {{{page_title|}}} | {{{page_title}}} | Welcome to WikiSEO}}
 |title_mode={{{title_mode|}}}
 |keywords={{{keywords|}}}
 |description={{{description|}}}
 |published_time={{REVISIONYEAR}}-{{REVISIONMONTH}}-{{REVISIONDAY2}}
}}

{{#seo:
 |title_mode=append
 |title=Example SEO Wiki
 |keywords=WikiSEO, SEO, MediaWiki
 |description=An example description for this wiki
 |image=Wiki_Logo.png
 |image_alt=Wiki Logo
 |site_name=Example SEO Wiki
 |locale=en_EN
 |type=website
 |modified_time={{REVISIONYEAR}}-{{REVISIONMONTH}}-{{REVISIONDAY2}}
 |published_time=2020-11-01
}}

Usage in lua modules[edit]

-- Module:SEO
local seo = {}

--[[
argTable format:
{
  title_mode = 'append',
  title = 'Example Seo Wiki',
  keywords = 'WikiSEO, SEO, MediaWiki',
  -- ...
}
]]--
function seo.set( argTable )
  mw.ext.seo.set( argTable )
end

function seo.setStatic()
  mw.ext.seo.set{
    title_mode = 'append',
    title = 'Example Seo Wiki',
    keywords = 'WikiSEO, SEO, MediaWiki',  
  }
end

return seo

The module would now be callable as {{#invoke:SEO|set|title=ExampleTitle|keywords=WikiSEO, SEO, MediaWiki}} or {{#invoke:SEO|setStatic}}.

Hreflang Attributes[edit]

{{#seo:
 |hreflang_de-de=https://example.de/page
 |hreflang_nl-nl=https://example.nl/page-nl
 |hreflang_en-us=https://website.com/
}}

<link rel="alternate" href="https://example.de/page" hreflang="de-de">
<link rel="alternate" href="https://example.nl/page-nl" hreflang="nl-nl">
<link rel="alternate" href="https://website.com/" hreflang="en-us">

Maintenance Script[edit]

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 description property set in the page properties table.

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

A list of namespace ids needs to be given in order for the script to work: 

# Run only in main namespace
php maintenance/GenerateDescription.php 0

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

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