给WordPress博客添加meta
Meta Tags in WordPress
As a search engine prowls your site, it gathers information from the title, headings, content, and Meta Tags such as description or keywords. It compares the words within each of these sections and "ranks" the site dependent upon how well the information matches. We have more information on how to maximize your meta tag references below.
It is important for website developers to understand that a default installation of WordPress does not contain the description and keywords meta tag data. Meta tags can be added manually, through changes to the Theme template files or through WordPress Plugins.
Meta Tags were created early on to provide concise information about a website. Meta tags list information about the web page, such as the author, keywords, description, type of document, copyright, and other core information.
meta tag for description示例:
<meta name="description" content="This is the description sentence or short paragraph about the article or post." />
常用meta tags示例：
<meta name="resource-type" content="document" /> <meta http-equiv="content-type" content="text/html; charset=US-ASCII" /> <meta http-equiv="content-language" content="en-us" /> <meta http-equiv="author" content="Harriet Smith" /> <meta http-equiv="contact" content="harrietsmith@harrietsmith.us" /> <meta name="copyright" content="Copyright (c)1997-2004 Harriet Smith. All Rights Reserved." /> <meta name="description" content="Story about my dog giving birth to puppies." /> <meta name="keywords" content="stories, tales, harriet, smith, harriet smith, storytelling, day, life, dog, birth, puppies, happy" />

当然，我们可以通过WordPress插件类如All in One SEO Pack实现自动生成meta和tags，但是插件加载需要耗费一定的时间，我们可以通过代码实现meta和tags的实现。
$description = "博客描述";
$keywords = "博客关键字";
} elseif (is_single()){
if ($post->post_excerpt) {
$description = $post->post_excerpt;
} else {
$description = substr(strip_tags($post->post_content),0,270);
}
$keywords = "";
$tags = wp_get_post_tags($post->ID);
foreach ($tags as $tag ) {
$keywords = $keywords . $tag->name . ", ";
}
}
?>
<meta name="keywords" content="<?=$keywords?>" />
<meta name="description" content="<?=$description?>" />
编辑WordPress主题的header.php文件，将上面的代码复制到<head></head>之间，同时将“博客描述”“博客关键字”替换成你自己的设置。
通过is_home和is_single实现对博客首页和文章页的判断，上面代码中的270是description摘要长度。

学习到了，用的第二种办法，呵。
