SG Optimizer

由 SiteGround 開發

外掛說明

這個外掛設計用來將 WordPress 網站連結至 SiteGround Performance 服務，因此它無法執行於其他主機服務提供商。

SG Optimizer 外掛包含多項處理指定效能最佳化的功能。

外掛相關設定

如需進一步了解這個外掛的運作方式，請參閱 SG Optimizer 教學課程。

SuperCacher 設定

In this tab, you can configure your Dynamic Caching to store your content in the server’s memory for faster access and Memcached which stores frequently executed queries to your database and reuses them for better performance. Make sure you’ve enabled them from your Site Tools or cPanel before using the plugin. You can also enable Automatic Cache purge. This will perform a Full Purge on page, posts, and category deletion, plugin and theme activation, deactivation, or update, and on WordPress core updates. Enabling the Browser-specific caching will create different cache versions based on the user agent used. From Exclude Post Types you can exclude the ones you don’t want to be cached at all. You can also exclude specific URLs or use a wildcard to exclude any sub-pages of a specific “parent-page”. We have also provided a test tool where you can check if a specific URL has Dynamic caching actually running.

主機環境最佳化

Here, you can force HTTPS for your site, enable or disable Gzip Compression and Browser Caching rules. You can activate Database Optimization which will remove all unnecessary items from your database and optimize its tables. If you are using the InnoDB storage engine, the optimization of tables is done automatically by the engine. Use DNS-Prefetching to increase load speeds for external resources. It works by resolving the domain name, before a resource is requested. You can also manage Heartbeat Control to modify the frequency of the WP Heartbeat for different locations. By default, the WordPress Heartbeat API checks every 15 seconds on your post edit pages and every 60 seconds on your dashboard and front end whether there are scheduled tasks to be executed. With this option, you can make the checks run less frequently or completely disable them.

網站前端最佳化

In this tab, you can enable or disable Minification of your HTML, JS and CSS resources. You can activate/deactivate JS and CSS combinations to reduce the numbers of requests to the server. With the Web Fonts Optimization we’re changing the default way we load Google fonts. A preconnect link for Google’s font repository will be added in your head tag. This informs the browser that your page intends to establish a connection to another origin, and that you’d like the process to start as soon as possible. In addition, all other local fonts will be preloaded so browsers can cache and render them faster. Also when combined with CSS Combination, we will change the font-display property to swap or add it if it’s missing, so we ensure faster rendering. You can Disable Emojis support in your pages to prevent WordPress from detecting and generating emojis on your pages. You can also Remove Query Strings from static resources to improve their caching.

圖片最佳化

Here, you can enable or disable automatic optimization for your newly uploaded images or bulk optimize your old ones. You can enable the generation of WebP images for newly uploaded images or generate WebP copies of your existing ones. WebP is a next generation image format supported by modern browsers which greatly reduces the size of your images. If the browser does not support WebP, the original images will be loaded. If you wish, you can delete all WebP copies of your images and original images will be loaded by default. You can also enable or disable Lazy Load for various assets such as iframes, videos, thumbnails, widgets, shortcodes and more. You can also enable Lazy Load for mobile requests. You have an option to exclude specific images from Lazy Loading. This is done by adding the class of the image in the tab.

Speed Test

我們的效能檢查由 Google PageSpeed 技術提供，網站管理員可透過這項檢查確認網站經過最佳化後的成效。系統會提供包含額外資訊的詳細測試結果，讓使用者瞭解如何進行更加深入的網站最佳化。

Full-page Caching on CloudFlare

Тhis optimization links your WordPress site with Cloudflare and sets the necessary rules and workers in order to enable full-page caching on Cloudflare edges in order to improve your TTFB and overall site performance. The tab will be available only if you have properly configured your installation to work with the CDN.

外掛相容性

如果開發的外掛無法觸發 WordPress 標準勾點，或開發的外掛需要 SG Optimizer 清除快取，外掛開發者可以在程式碼中使用以下公開函式：

if (function_exists('sg_cachepress_purge_cache')) {
    sg_cachepress_purge_cache();
}

更棒的是，網站管理員可以將網址傳遞至函式，便能清理指定快取，而非清理全站快取。範例程式碼如下：

if (function_exists('sg_cachepress_purge_cache')) {
    sg_cachepress_purge_cache('https://yoursite.com/pluginpage');
}

網站管理員可以使用針對性設計的篩選器，從合併及最小化/壓縮的樣式表中排除特定樣式。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_css_combine_exclude', 'css_combine_exclude' );
function css_combine_exclude( $exclude_list ) {
    // Add the style handle to exclude list.
    $exclude_list[] = 'style-handle';
    $exclude_list[] = 'style-handle-2';

    return $exclude_list;
}

add_filter( 'sgo_css_minify_exclude', 'css_minify_exclude' );
function css_minify_exclude( $exclude_list ) {
    // Add the style handle to exclude list.
    $exclude_list[] = 'style-handle';
    $exclude_list[] = 'style-handle-2';

    return $exclude_list;
}

網站管理員可以使用針對性設計的篩選器，從最小化/壓縮的指令碼中排除特定指令碼。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_js_minify_exclude', 'js_minify_exclude' );
function js_minify_exclude( $exclude_list ) {
    $exclude_list[] = 'script-handle';
    $exclude_list[] = 'script-handle-2';

    return $exclude_list;
}

網站管理員可以使用針對性設計的篩選器，從合併的指令碼中排除特定指令碼。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_javascript_combine_exclude', 'js_combine_exclude' );
function js_combine_exclude( $exclude_list ) {
    $exclude_list[] = 'script-handle';
    $exclude_list[] = 'script-handle-2';

    return $exclude_list;
}

網站管理員可以使用針對性設計的篩選器，從合併的指令碼中排外部除指令碼。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_javascript_combine_excluded_external_paths', 'js_combine_exclude_external_script' );
function js_combine_exclude_external_script( $exclude_list ) {
    $exclude_list[] = 'script-host.com';
    $exclude_list[] = 'script-host-2.com';

    return $exclude_list;
}

網站管理員可以使用針對性設計的篩選器，從合併的指令碼中排除內嵌指令碼。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_javascript_combine_excluded_inline_content', 'js_combine_exclude_inline_script' );
function js_combine_exclude_inline_script( $exclude_list ) {
    $exclude_list[] = 'first few symbols of inline content script';

    return $exclude_list;
}

網站管理員可以使用針對性設計的篩選器，從非同步載入的指令碼中排除特定指令碼。以下是範例程式碼，網站管理員可以將這些程式碼加入佈景主題的 functions.php 檔案中：

add_filter( 'sgo_js_async_exclude', 'js_async_exclude' );
function js_async_exclude( $exclude_list ) {
    $exclude_list[] = 'script-handle';
    $exclude_list[] = 'script-handle-2';

    return $exclude_list;
}

網站管理員可以使用以下篩選器，藉以排除網址或包含指定查詢參數的網址：

add_filter( 'sgo_html_minify_exclude_params', 'html_minify_exclude_params' );
function html_minify_exclude_params( $exclude_params ) {
    // Add the query params that you want to exclude.
    $exclude_params[] = 'test';

    return $exclude_params;
}

add_filter( 'sgo_html_minify_exclude_urls', 'html_minify_exclude' );
function html_minify_exclude( $exclude_urls ) {
    // Add the url that you want to exclude.
    $exclude_urls[] = 'http://mydomain.com/page-slug';

    return $exclude_urls;
}

網站管理員可以使用以下篩選器，藉以在延遲載入中排除指定類別的圖片：

add_filter( 'sgo_lazy_load_exclude_classes', 'exclude_images_with_specific_class' );
function exclude_images_with_specific_class( $classes ) {
    // Add the class name that you want to exclude from lazy load.
    $classes[] = 'test-class';

    return $classes;
}

使用者評論

GTMetrix from B down to F

2021 年 5 月 7 日
After using this SGO, within 24 hours, my site grade dropped from B to F. No choice but deactivate it.

It works fine but be wary before deactivating

2021 年 5 月 18 日
Works fine but there are a few major issues: 1. Deactivating the plugin leaves the last-cached version as the live version, so before you deactivate this plugin you have to turn caching on, and purge all cache, and I'm not entirely sure that that will stop it. 2. There's no developer option. If you're trying to change CSS you have to deactivate the plugin, and hope that you remember to reactivate it later otherwise it shows the last version that it cached (yes when deactivated), not the live version. 3. Using the Combine CSS Files option kills google fonts and :root variables.
