- 确保页面速度快
快速的页面加载速度对于电子商务网站至关重要。因此,我们可以通过以下方法来确保页面加载速度快:
// 移除 jQuery 库的版本参数
function remove_jquery_version_parameter( $src ) {
if ( strpos( $src, ‘jquery’ ) ) {
$src = remove_query_arg( ‘ver’, $src );
}
return $src;
}
add_filter( ‘script_loader_src’, ‘remove_jquery_version_parameter’ );
add_filter( ‘style_loader_src’, ‘remove_jquery_version_parameter’ );
// 移除 WordPress 自带的 emoji 脚本
function disable_emojis() {
remove_action( ‘wp_head’, ‘print_emoji_detection_script’, 7 );
remove_action( ‘admin_print_scripts’, ‘print_emoji_detection_script’ );
remove_action( ‘wp_print_styles’, ‘print_emoji_styles’ );
remove_action( ‘admin_print_styles’, ‘print_emoji_styles’ );
remove_filter( ‘the_content_feed’, ‘wp_staticize_emoji’ );
remove_filter( ‘comment_text_rss’, ‘wp_staticize_emoji’ );
remove_filter( ‘wp_mail’, ‘wp_staticize_emoji_for_email’ );
add_filter( ‘tiny_mce_plugins’, ‘disable_emojis_tinymce’ );
}
add_action( ‘init’, ‘disable_emojis’ );
function disable_emojis_tinymce( $plugins ) {
if ( is_array( $plugins ) ) {
return array_diff( $plugins, array( ‘wpemoji’ ) );
} else {
return array();
}
}
// 压缩 HTML
function compress_html( $html ) {
$compressed = preg_replace( ‘/\s{2,}/’, ‘ ‘, $html );
$compressed = preg_replace( ‘//’, ”, $compressed );
return $compressed;
}
function maybe_compress_html() {
if ( ! is_user_logged_in() && ! is_admin() ) {
ob_start( ‘compress_html’ );
}
}
add_action( ‘init’, ‘maybe_compress_html’ );
- 使用schema.org结构化数据
使用schema.org结构化数据有助于搜索引擎了解您网站上的内容,并提高SEO排名。下面是一个示例代码片段,用于在电子商务网站上添加产品结构化数据:
function add_product_schema() {
if ( is_single() && ‘product’ == get_post_type() ) {
$product = wc_get_product( get_the_ID() );
$json_ld = array(
‘@context’ => ‘http://schema.org’,
‘@type’ => ‘Product’,
‘name’ => $product->get_name(),
‘description’ => $product->get_description(),
‘sku’ => $product->get_sku(),
‘offers’ => array(
‘@type’ => ‘
‘Offer’, ‘price’ => $product->get_price(), ‘priceCurrency’ => get_woocommerce_currency(), ‘availability’ => ‘http://schema.org/‘ . ( $product->is_in_stock() ? ‘InStock’ : ‘OutOfStock’ ), ), ); echo ‘<script type=”application/ld+json”>’ . wp_json_encode( $json_ld ) . ‘</script>’; } } add_action( ‘wp_head’, ‘add_product_schema’ );
- 优化页面标题和描述
页面标题和描述是搜索引擎排名的重要因素。在WordPress中,我们可以通过以下代码片段来设置页面标题和描述:
function custom_meta_title() { global $post; if ( is_front_page() ) { $title = get_bloginfo( ‘name’ ); } elseif ( is_home() ) { $title = get_the_title( get_option( ‘page_for_posts’, true ) ); } elseif ( is_singular() ) { $title = get_the_title( $post->ID ); } elseif ( is_category() ) { $title = single_cat_title( ”, false ); } elseif ( is_tag() ) { $title = single_tag_title( ”, false ); } elseif ( is_author() ) { $title = get_the_author_meta( ‘display_name’, $post->post_author ); } elseif ( is_search() ) { $title = ‘Search Results for ‘ . get_search_query(); } else { $title = get_bloginfo( ‘name’ ); } return $title; } add_filter( ‘pre_get_document_title’, ‘custom_meta_title’ );
function custom_meta_description() { global $post; if ( is_singular() ) { $description = get_the_excerpt(); if ( empty( $description ) ) { $description = wp_trim_words( $post->post_content, 30 ); } } elseif ( is_category() || is_tag() ) { $description = term_description(); } elseif ( is_home() || is_front_page() ) { $description = get_bloginfo( ‘description’ ); } else { $description = ”; } return $description; } add_filter( ‘get_the_excerpt’, ‘custom_meta_description’ ); add_filter( ‘excerpt_more’, ‘__return_false’ );
- 优化页面URL
页面URL也是SEO排名的重要因素。在WordPress中,我们可以通过以下代码片段来优化页面URL:
function custom_permalink( $permalink, $post ) { if ( ‘product’ === $post->post_type ) { $permalink = home_url( ‘/products/’ . $post->post_name . ‘/’ ); } return $permalink; } add_filter( ‘post_type_link’, ‘custom_permalink’, 10, 2 );
以上是一些在编写适用于电子商务的WordPress主题时应该注意的最佳实践和示例代码片段。当然,这只是冰山一角,还有很多其他的优化方法可以应用于电子商务网站。
function custom_rewrite_rule() { add_rewrite_rule( ‘^products/([^/]*)/?’, ‘index.php?product=$matches[1]’, ‘top’ ); } add_action( ‘init’, ‘custom_rewrite_rule’ );
