在 WordPress 5.5 中，引入了一项新功能XML Sitemaps Functionality，它将基本的、可扩展的XML 站点地图功能添加到 WordPress核心。
在 5.5 版中，WordPress 将在/wp-sitemap.xml 使用站点地图索引. 这是包含 WordPress 站点公开的所有站点地图页面列表的主要 XML 文件。默认此功能是开启状态，如果你的站点打开是404，那么可能是主题或插件禁止了它，可以使用wp_sitemaps_enabled来开启：
add_filter( 'wp_sitemaps_enabled', '__return_true' );站点地图索引最多可包含 50000 个站点地图，单个站点地图最多可包含 2000 个（可过滤的）条目。
默认情况下，所有帖子类型、分类法和用户都会生成 XML 站点地图。Oxygen模板也会包含在站点地图中：https://example.com/wp-sitemap-posts-ct_template-1.xml，这是没有意义的，因为这些模板并不意味着面向公众。
禁用Oxygen氧气模板的 WP 站点地图
使用Oxygen创建的网站，首先要排除这条链接: https://example.com/wp-sitemap-posts-ct_template-1.xml，使用代码片段插件添加如下PHP代码
add_filter(
'wp_sitemaps_post_types',
function( $post_types ) {
unset( $post_types['ct_template'] );
return $post_types;
}
);如果您希望禁用多种帖子类型的 XML 站点地图，只需将它们添加到新行中，unset()如下所示：
add_filter(
'wp_sitemaps_post_types',
function( $post_types ) {
unset( $post_types['ct_template'] );
unset( $post_types['surl'] );
return $post_types;
}
);禁用作者的 WP 站点地图
大多数的网站都不需要作者的地图链接 https://www.acerackingsystem.com/wp-sitemap-users-1.xml，PHP排除代码如下：
add_filter( 'wp_sitemaps_add_provider', function ($provider, $name) {
return ( $name == 'users' ) ? false : $provider;
}, 10, 2);从站点地图中排除某个特定的帖子
我们常常会有一些特定的帖子，不希望被搜索引擎收录的，那么最好也将它们从站点地图中排除。
过滤器wp_sitemaps_posts_query_args可用于从站点地图中排除特定帖子。下面是我的一个商城，排除购物车和结账页面的例子，将下面的代码加到子主题的functions.php，亲测有效：
// disable cart and check out page
function disable_sitemap_specific_page($args, $post_type) {
if ('page' !== $post_type) return $args;
$args['post__not_in'] = isset($args['post__not_in']) ? $args['post__not_in'] : array();
$args['post__not_in'][] = 23;
$args['post__not_in'][] = 24;
return $args;
}
add_filter('wp_sitemaps_posts_query_args', 'disable_sitemap_specific_page', 10, 2);下面是自定义站点地图排除帖子，页面，产品等PHP示例
