An fork of Add HTML Meta and Title extension for MediaWiki.
Copy Add_HTML_Meta_and_Title.php into 'extensions' directory. Add following into your LocalSettings.php
$wgSitename = "My Wiki";
$wgAllowDisplayTitle = true;
$wgRestrictDisplayTitle = false;
require_once "$IP/extensions/Add_HTML_Meta_and_Title/Add_HTML_Meta_and_Title.php';
<seo title="word1,word2" metakeywords="word3,word4" metadescription="word5,word6" google-site-verification="123456789-abfd123456" />
...or the shorter...
<seo title="word1,word2" metak="word3,word4" metad="word5,word6" google-site-verification="123456789-abfd123456" />
...these words are added to the HTML title and meta headers. This makes SEO (search engine optimization) with MediaWiki easier.
For example, the above would become:
<title>Original title, word1,word2</title> (the string ", word1,word2,..." is added)
<meta name="keywords" content="word3,word4" />
<meta name="description" content="word5,word6" />
<meta name="google-site-verification" content="123456789-abfd1234562 />
(These are new meta tags - existing meta tags are left untouched.)
Create a template called Seo, insert following wikitext.
{{DISPLAYTITLE:{{{pagetitle}}} }}
<seo title={{{pagetitle}}} metakeywords="{{{meta_keywords}}}"/>
Now you can use more Wiki-flavoured style like following.
{{seo
|pagetitle=My Main Page
|meta_keywords=super,long,increase,inches}}
