Mediawiki增加Google AdSense
在建好mediawiki网站之后，放广告可以增加一点收入。其中Google AdSense是一个不错的选择。首先，需要申请一个Google AdSense帐号，点击本页左下角的“Google AdSense”图标就可以打开申请页面。在获得google批准后（不一定多长时间），登录你的AdSense帐户，上面有相当明白的中文说明，可以很容易取得广告代码。
Google AdSense的广告显示简洁明快，很容易与wiki网站搭配。
打开skins/monobook.php文件，我们需要在里面找到加入广告代码的位置。代码通常如下：（以mediawiki 1.7为例）
<?php
/**
* MonoBook nouveau
*
* Translated from gwicke's previous TAL template version to remove
* dependency on PHPTAL.
*
* @todo document
* @package MediaWiki
* @subpackage Skins
*/
if( !defined( 'MEDIAWIKI' ) )
die( -1 );
/** */
require_once('includes/SkinTemplate.php');
/**
* Inherit main code from SkinTemplate, set the CSS and template filter.
* @todo document
* @package MediaWiki
* @subpackage Skins
*/
class SkinMonoBook extends SkinTemplate {
/** Using monobook. */
function initPage( &$out ) {
SkinTemplate::initPage( $out );
$this->skinname= 'monobook';
$this->stylename = 'monobook';
$this->template= 'MonoBookTemplate';
}
}
/**
* @todo document
* @package MediaWiki
* @subpackage Skins
*/
class MonoBookTemplate extends QuickTemplate {
/**
* Template filter callback for MonoBook skin.
* Takes an associative array of data set from a SkinTemplate-based
* class, and a wrapper for MediaWiki's localization database, and
* outputs a formatted page.
*
* @access private
*/

选择你想添加adsense广告的位置，并把广告代码直接添加进去。（如果希望自己调整显示效果，也可以在广告代码外面添加一层div，以便设定底图、边框等CSS样式）。
广告代码的实际显示位置见文尾附图。通常google adsense只允许在同一个页面上放3组广告、2组搜索、一个广告连接单元和一个推介。你可以根据需要在不同位置添加不同的广告代码，但不要放多了。
根据网页内容不同，放置adsense广告后每1000次页面访问可获得1-5元收入。如果您准备做google adsense广告，不妨点击本页左下角的adsense图标链接来申请帐号，谢谢啦^_^
更多说明
* 如果能在文章正文区域放置广告，其广告效果无疑更好。经媒体wiki试验，若使用iframe插件，则在正文div部分要用3个div来布局，而使用表格布局会导致iframe无法使用。更多试验结果还有待大家分享。
* 放置广告无疑会影响页面效果，很多读者不喜欢看到wiki里面有广告。作为折衷方案，可以将不含广告代码的源程序改名另存一下（例如改名为monobook_no_ad.php）。上传到skins/ 文件夹之后，用户就能在自己的参数设置页面中选择这个皮肤。
* 前文的增加广告代码方法，同样适用于网页计数器等代码的放置。
