Example `image = Local_file_to_use.png. Alternatively a full url to an image can be used, image_width and image_height will then have to be set manually. If no parameter is set, the extension will use $wgLogo as a fallback or the local file set through $wgWikiSeoDefaultImage`.

1. Examples
   1. Adding static values

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

Adding dynamic values

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}}
 |titlemode={{{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
}}

Using the lua module

WikiSEO exposes a lua method as mw.ext.seo.set

Example module:

-- 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|add|title=ExampleTitle|keywords=WikiSEO, SEO, MediaWiki}} or {{#invoke:SEO|addStatic}}.

Hreflang Attributes

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

Will generate the following <link> elements:

html
<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">

Title Modes

Example: Page with title Example Page

Append

{{#seo:
 |title_mode=append
 |title=Appended Title
}}

HTML Title result: Example Page - Appended Title

Prepend

{{#seo:
 |title_mode=prepend

}}

HTML Title result: Prepended Title - Example Page

 |title_separator=<nowiki>&nbsp;>>&nbsp;</nowiki>
}}

HTML Title result: Prepended Title >> Example Page

 |title_mode=replace
 |title=Replaced Title
}}

HTML Title result: Replaced Title

Hooks

WikiSEO exposes Hooks that allow to customize the metadata that gets added to the page and saved in page props.

• WikiSEOPreAddMedatada
  • onWikiSEOPreAddMedatada( &$metadata )
  • An array of key-value pairs validated through Validator::validateParams
  • Run right before the instantiation of the metadata generators
• WikiSEOPreAddPageProps
  • onWikiSEOPreAddPageProps( &$metadata )
  • An array of key-value pairs validated through Validator::validateParams
  • Run right before setting the page props
• WikiSEOLuaPreAddPageProps
  • onWikiSEOLuaPreAddPageProps( &$metadata )
  • An array of key-value pairs validated through Validator::validateParams
  • Run right before setting the page props
  • Only run when the lua module is called | $wgWikiSeoSocialImageBackgroundColor = #14181f; |

Known Issues

Extension:PageImages will add an og:image tag if an image is found on the page. This overwrites any og:image tag set using this extension. There is currently no way to disable PageImages setting the meta tag.

Notes

If you only want to override the display title on pages (not append words to it), you might also look at the DISPLAYTITLE tag in combination with the Manual:$wgAllowDisplayTitle and Manual:$wgRestrictDisplayTitle settings.

schema.org

The `SchemaOrg` generator will set a SearchAction property based on Special:Search. The properties publisher and author will be set to Organization with the name set to the content of `$wgSitename`. `dateModified` will be automatically set by fetching the latest revision timestamp. If no published_time is set, datePublished will be set to the latest revision timestamp.

OpenGraph

`article:modified_time will be automatically set by fetching the latest revision timestamp. If no published_time is set, article:published_time` will be set to the latest revision timestamp. This can be disabled on a per-page basis by setting modified_time=- through the parser.

Extending this extension

Metadata generators live in the `includes/Generator/Plugins` directory. A generator has to implement the `GeneratorInterface`. To load the generator simply add its name to `$wgMetadataGenerators`.
