我的Google分析帐户建议我在Head部分的网页中添加结构化数据标记。我标记了我想要的内容并创建了HTML。但是，当我将该代码放在我标记的页面上的HTML中时，我没有看到Head部分。所以，我只是把它放在页面的顶部。当我将它添加到页面顶部时，它会创建一个空格。可以将此代码放在页面底部。代码如下所示：

"description" : "IT Training Courses",

} ]
</script>
看看这里：https://codex.wordpress.org/Plugin_API/Action_Reference/wp_head
<?php
add_action('wp_head', 'your_function');
?>
在functions.php中，用你的结构数据HTML创建your_function（），该函数应该在<head>中加载它
function your_function() {
?>
