在SEO中网站的链接结构以及目录层次都非常重要,百度官方的SEO白皮书内就强调了,一个好的URL结构不仅能让搜索引擎更加容易了解到网站内 容,而且也利于访客记忆。很多SEO书籍中都提到了,网站URL的目录层次最好不要超过三层。当然如果URL中包含关键词就更好了。那么wordpress网站该如何设定网站的伪静态才能符合SEO标准呢?
文章页:
应采用“/%category%/%post_id%.html”格式的链接,如下图:
采用这样输出的网址就是“http://域名/分类名/“文章唯一id 都说接在域名后面的第一个/后面的东西对于搜索引擎权重越大,其实不然,这样反而会让网站结构变得杂乱不堪,wordpress的默认的结构是“http://域名/category/分类/“ 由此可见域名/后面应该接的就是分类了,可是这里却有了一个category 所以所以需要去掉category 达到效果 变成http://域名/分类/
把这段代码加到主题里面的functions.php里面:
add_action( 'load-themes.php', 'no_category_base_refresh_rules'); add_action('created_category', 'no_category_base_refresh_rules'); add_action('edited_category', 'no_category_base_refresh_rules'); add_action('delete_category', 'no_category_base_refresh_rules'); function no_category_base_refresh_rules() { global $wp_rewrite; $wp_rewrite -> flush_rules(); } // register_deactivation_hook(__FILE__, 'no_category_base_deactivate'); // function no_category_base_deactivate() { // remove_filter('category_rewrite_rules', 'no_category_base_rewrite_rules'); // // We don't want to insert our custom rules again // no_category_base_refresh_rules(); // } // Remove category base add_action('init', 'no_category_base_permastruct'); function no_category_base_permastruct() { global $wp_rewrite, $wp_version; if (version_compare($wp_version, '3.4', '<')) { // For pre-3.4 support $wp_rewrite -> extra_permastructs['category'][0] = '%category%'; } else { $wp_rewrite -> extra_permastructs['category']['struct'] = '%category%'; } } // Add our custom category rewrite rules add_filter('category_rewrite_rules', 'no_category_base_rewrite_rules'); function no_category_base_rewrite_rules($category_rewrite) { //var_dump($category_rewrite); // For Debugging $category_rewrite = array(); $categories = get_categories(array('hide_empty' => false)); foreach ($categories as $category) { $category_nicename = $category -> slug; if ($category -> parent == $category -> cat_ID)// recursive recursion $category -> parent = 0; elseif ($category -> parent != 0) $category_nicename = get_category_parents($category -> parent, false, '/', true) . $category_nicename; $category_rewrite['(' . $category_nicename . ')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?category_name=$matches[1]&feed=$matches[2]'; $category_rewrite['(' . $category_nicename . ')/page/?([0-9]{1,})/?$'] = 'index.php?category_name=$matches[1]&paged=$matches[2]'; $category_rewrite['(' . $category_nicename . ')/?$'] = 'index.php?category_name=$matches[1]'; } // Redirect support from Old Category Base global $wp_rewrite; $old_category_base = get_option('category_base') ? get_option('category_base') : 'category'; $old_category_base = trim($old_category_base, '/'); $category_rewrite[$old_category_base . '/(.*)$'] = 'index.php?category_redirect=$matches[1]'; //var_dump($category_rewrite); // For Debugging return $category_rewrite; } // Add 'category_redirect' query variable add_filter('query_vars', 'no_category_base_query_vars'); function no_category_base_query_vars($public_query_vars) { $public_query_vars[] = 'category_redirect'; return $public_query_vars; } // Redirect if 'category_redirect' is set add_filter('request', 'no_category_base_request'); function no_category_base_request($query_vars) { //print_r($query_vars); // For Debugging if (isset($query_vars['category_redirect'])) { $catlink = trailingslashit(get_option('home')) . user_trailingslashit($query_vars['category_redirect'], 'category'); status_header(301); header("Location: $catlink"); exit(); } return $query_vars; }
加 好代码后到后台再次固定链接即可。现在标签(Category)页面的链接就变成了以下这种结构:“http://域名/分类/“也就是说成功的去除了链接中的 category
上面关于网站网址结构对于seo优化的话说了不少了这里就不多说了。
刚才是去掉了分类页面的category 在wordpress里面还有一个标签在输出网址的时候也添加了一个tag 所以这里说的是去掉tag
在functions.php里面添加以下代码:
register_activation_hook(__FILE__,'no_tag_base_refresh_rules'); add_action('created_post_tag','no_tag_base_refresh_rules'); add_action('edited_post_tag','no_tag_base_refresh_rules'); add_action('delete_post_tag','no_tag_base_refresh_rules'); function no_tag_base_refresh_rules() { global $wp_rewrite; $wp_rewrite->flush_rules(); } register_deactivation_hook(__FILE__,'no_tag_base_deactivate'); function no_tag_base_deactivate() { remove_filter('tag_rewrite_rules', 'no_tag_base_rewrite_rules'); no_tag_base_refresh_rules(); } add_action('init', 'no_tag_base_permastruct'); function no_tag_base_permastruct() { global $wp_rewrite, $wp_version; if (version_compare($wp_version, '3.4', '<')) { $wp_rewrite -> extra_permastructs['post_tag'][0] = '%post_tag%'; } else { $wp_rewrite -> extra_permastructs['post_tag']['struct'] = '%post_tag%'; } } add_filter('tag_rewrite_rules', 'no_tag_base_rewrite_rules'); function no_tag_base_rewrite_rules($tag_rewrite) { $tag_rewrite=array(); $tags=get_tags(array('hide_empty'=>false)); foreach($tags as $tag) { $tag_nicename = $tag->slug; if ( $tag->parent == $tag_id ) { $tag->parent = 0; } $tag_rewrite['('.$tag_nicename.')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?tag=$matches[1]&feed=$matches[2]'; $tag_rewrite['('.$tag_nicename.')/page/?([0-9]{1,})/?$'] = 'index.php?tag=$matches[1]&paged=$matches[2]'; $tag_rewrite['('.$tag_nicename.')/?$'] = 'index.php?tag=$matches[1]'; } global $wp_rewrite; $old_tag_base = get_option('tag_base') ? get_option('tag_base') : 'tag'; $old_tag_base = trim($old_tag_base, '/'); $tag_rewrite[$old_tag_base . '/(.*)$'] = 'index.php?tag_redirect=$matches[1]'; return $tag_rewrite; } add_filter('query_vars', 'no_tag_base_query_vars'); function no_tag_base_query_vars($public_query_vars) { $public_query_vars[] = 'tag_redirect'; return $public_query_vars; } add_filter('request', 'no_tag_base_request'); function no_tag_base_request($query_vars) { if (isset($query_vars['tag_redirect'])) { $tag = user_trailingslashit($query_vars['tag_redirect'], 'post_tag'); $taglink = trailingslashit(get_option( 'home' )) . $tag; status_header(301); header("Location: $taglink"); exit(); } return $query_vars; }
加上以上代码标签页就变成“http://域名/标签/ “简单的说就是去掉tag
但是现在还有一个问题就是对于搜索引擎,一个页面就是后面没有“/“ 后面有/才是一个目录
那么如何让分类目录的链接变成“http://www.域名.com/分类名/“ 那么如何让标签目录的链接变成“http://www.域名.com/标签名/“
在functions.php里面添加以下代码切记一定要放在最后不然出问题就不好了
if (is_admin()) return; $permalink_structure = get_option('permalink_structure'); if (!$permalink_structure || '/' === substr($permalink_structure, -1)) return; add_filter('user_trailingslashit', 'ppm_fixe_trailingslash', 10, 2); function ppm_fixe_trailingslash($url, $type) { if ('single' === $type) return $url; return trailingslashit($url); }
这样就好了,对于网站网址结构的SEO优化!
