Automated Installation with Composer[edit]

This is possible starting with MediaWiki 1.22 and later. Follow the instructions at the Composer help page to add the package tinymighty/wiki-seo to your composer.json file.

Manual Installation[edit]

  • Download and place the file(s) in a directory called WikiSEO in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'WikiSEO' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'WikiSEO' );, you need to use:

require_once "$IP/extensions/WikiSEO/WikiSEO.php";
If you are installing the extension via a Git clone, be sure to specify the directory name as WikiSEO:
cd extensions

git clone https://github.com/tinymighty/wiki-seo.git WikiSEO

cd WikiSEO

git checkout 1.2.2


The extension can be used via the <seo> tag or the {{#seo}} parser function. Both accept the following named parameters in any order.

tags for general use
  • title
The title you want to appear in the html title tag
  • titlemode
Set to append, prepend, or replace (default) to define how the title will be amended.
  • titleseparator
The separator in case titlemode was set to append or prepend; "-" (default)

  • description
A text description for the meta description tag

Adding static values[edit]

<seo title="Your page title" titlemode="append" keywords="these,are,your,keywords" description="Your meta description"></seo>

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...

 |title={{#if: {{{page_title|}}} | {{{page_title}}} | Welcome to WikiSEO}}

This extension has been rewritten to current MediaWiki standards based on the Add HTML Meta and Title extension by Vladimir Radulovski. As I have also made some design changes, I have released it as a separate extension, but it is backwards compatible (it provides a <seo> tag, and permits the use of the metakeywords, metak, metadescription and metad attributes.
