SG Optimizer

Descripción

This plugin is designed to link WordPress with the SiteGround Performance services. It WILL NOT WORK on another hosting provider.

The SG Optimizer plugin has few different parts handling speciffic performance optimizations:

Configuración

For detailed information on our plugin and how it works, please check out our SG Optimizer Tutorial.

SuperCacher Settings

In this tab, you can configure your Dynamic Caching and Memcached. Make sure you’ve enabled them from your cPanel before using the plugin. You can enable/disable the automatic cache purge, exclude URLs from the cache and test your pages if they are properly cached.

Environment Optimization

Here, you can force HTTPS for your site, switch between different PHP Versions (compatibility check available), and enable or disable Gzip Compression and Borwser Caching rules for your site.

Frontend Optimization

In this tab, you can enable or disable Minification of your HTML, JS and CSS resources, remove the Emoji support and remove the query strings from your static resources.

Image Optimization

Here, you can enable or disable optimization for your newly uploaded images, bulk optimize your old ones and enable lazy loading for your site images.

Plugin Compatibility

If your plugin does not trigger standard WordPress hooks or you need us to purge the cache, you can use this public function in your code:

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

Preferrably, you can pass an URL to the function to clear the cache just for it instead of purging the entire cache. For example:

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

You can exclude styles from being combined and minified using the filters we’ve designed for that purpose. Here’s an example of the code, you can add to your functions.php file:

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;
}

You can exclude script from being minified using the filter we’ve designed for that purpose. Here’s an example of the code, you can add to your functions.php file:

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;
}

You can exclude script from being loaded asynchronous using the filter we’ve designed for that purpose. Here’s an example of the code, you can add to your functions.php file:

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;
}

You can exclude url or url that contain specific query param using the following filters:

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;
}

You can exclude images from Lazy Load using the following filter:

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;
}

Reseñas

I still don't know why but I've realized that it needs 1.5 seconds to get the first byte of every page of my site. Why? Because this plugin chose not to cache them.
9 de diciembre, 2019
I have tested SG Optimizer setup & plugin several times, and every single time it gave terrible scores in key speed and performance checking tools like Google Pagespeed Insights and GTMetrix. I'm using a free plugin combo now that's improved things tremendously (Autooptimze and WP Supercache), this combination had really boosted the performance of my site more that SGOptimizer ever even came close to doing. I have reached out to SiteGround "support" several times in the past, so this has been going on for quite a while with everyone scratching their heads with no answer, so I have had to do a ton of testing on my own and finally figured things out myself that your plugin was the culprit for destroying my page speed rankings (and very possibly has impacted my SEO rankings being that page speed is such an important ranking factor these days). I am extremely disappointed in what I have discovered and have lost a lot of trust in Siteground overall after this whole ordeal. (Yes I had the lastest plugin installed, Yes I had things activated in a hosting panel, Yes I tested with other plugins disabled, Yes I spoke with "support" several times about the issue with no solution over besides hire a developer, Yes, I tested in multiple times, Yes to all of that! Bottom line is that the plugin failed to live up to all the hype.

SGO helped me to score 99% in google page speed by compressing and combining js and css files, optimizing and lazy loading the images and setting up my .htaccess for better cache policy
28 de noviembre, 2019
I have had a lot of problems with 'combine css files'. They were resolved with the help of Siteground support. Some suggestions to improve the plugin: 1. Combine CSS Files: I didn't know that I had to click a second time in the field to see all the files I could exclude (One of them caused the problem.). 2. The problem stayed even after disabling 'combine css files'. 3. I didn't know that purge SG cache in dashboard didn't empty the whole cache. You have to do that in c panel. Why not in dashboard?
