Any concerns about module configuration and usage?
Get an individual training session to explore how the extension works and what practices to implement to achieve the desired result. Save time spent searching for the right settings - discuss configuration cases suitable for your business with the experts and work out the flow that your team needs.
The solution has 3 feature sets, which are based on the required optimization level.
As mentioned above, the PRO version consists of 3 modules: code optimization, image optimization and lazy load. All these extensions should be configured separately. To do this, go to Stores → Configuration → Amasty Extensions. Start with the Google Page Speed Optimizer tab.
Before starting the optimization, check your website’s current Google score right from the admin panel using the Diagnostic option. This built-in testing tool helps you to measure the result after enabling each option. Diagnostics include the tips for Magento optimization based on the current score and the metrics that should be improved. Follow the recommendations to get the most out of the extension. Moreover, for your convenience, Magento performance optimization tips display a precise way for the feature that should be enabled to improve a specific metric.
You may see the desktop and mobile page speed scores separately. The informative block also contains Google recommendations.
Follow the recommendations and check the result once more. You will see the result in the After tab.
This part of the extension contains code optimization and some other settings to make your webstore load faster.
Using the settings, you can reduce HTML, CSS and JS code size. The extension removes all unnecessary line breaks, tabs, comments and spaces. Also, it includes some advanced settings, such as server push.
Minify HTML - set the option to Yes to enable HTML minification.
bin/magento setup:static-content:deploy
In this tab you can create an advanced bundle of JS using Advanced JS Bundling feature and JS Minification that will significantly reduce the page size in kilobytes and increase the page load speed. Google rank for both mobile and desktop will be improved.
To run the optimization, set the Amasty JS Optimization option to Enabled.
Is Magento Cloud - set to Yes if you use Magento Cloud hosting platform.
Click Start.
Easily Clear Bundle if needed.
Step 1. After clicking the Start button, the extension starts preparing all the links for optimization.
Step 2. Links processing progress is displayed on the bar.
When all the links from the bundle are successfully processed, you can add specific pages to JavaScript bundle. Keep in mind that each link should be placed on a new line.
If any errors are found, the processing will be stopped and the error message will appear. You may check the particular link that caused a failure. For example, 3/5 links has been successfully processed and then the message appears. It means that the 4th link contains some problems. Easily click on it to check if it is valid or not and correct the link or page itself if needed.
Step 3. When optimization is finished, you will see the appropriate message and a list of commands that should be executed.
Previously, the setting 'Is Magento Cloud' was created for Magento Cloud usage. But, to avoid manual deployment, you can also use this setting even if you don't use the Cloud. Follow the steps below to set up an automatic deploy:
1. Set 'Is Magento Cloud' option to 'Yes'
2. Find the app/etc/config.php file. There you will see the list of installed modules. To create an optimization file, you will need the following massive:
'system' => [ 'default' => [ 'dev' => [ 'template' => [ 'minify_html' => 1 ], 'js' => [ 'merge_files' => 1, 'enable_js_bundling' => 1, 'minify_files' =>1 ] ] ] ]
3. Go back to your admin panel and click Run Optimization → Start.
4. The extension will generate the code that should be put into cloud repository:
5. Copy the generated code and paste it after ‘default’ arrow in app/etc/config.php:
6. Save the config.php file.
Include JS of the Admin Area Pages into Merged JS File - enable this option if you want to optimize the admin area as well.
Exclude URLs from JS Bundling and Merge - specify particular URLs that shouldn't be merged or minified. Start each URL or part of the URL from new line.
bin/magento setup:static-content:deploy
in the console after any changes in this block of settings have been made.
Move JavaScript To Page Bottom option helps to load all the important content before loading JS. The functionality improves pages loading time.
Ignore URL List - provide URLs of the pages on which JS shouldn't be moved to bottom.
Ignore Scripts that Contain - you may also specify particular scripts and their parts if you want them to exclude from moving.
If Amasty JS Optimization is Disabled, you can customize the way of code optimization. Besides Moving JS To Page Bottom, there are 4 additional options to reduce your JS code. You can also exclude particular URLs and scripts.
Merge JavaScript Files - select Yes to put all JS files into one. As a result, the number of queries will be reduced.
Enable JavaScript Bundling - enable this option to combine all JS files into few bundles and download them for each page. This helps to save time by reducing the number of server requests.
Minify JavaScript Files - set to Yes to enable JS minification.
Minify JavaScript in PHTML Files - enable this option to reduce the load time of non-cacheable pages by minifying JS in PHTML files when deploying statics.
Specify Path to Templates to be Ignored - exclude particular templates from minifying if needed.
Include JS of the Admin Area Pages into Merged JS File - enable this option if you want to optimize the admin area as well.
Exclude URLs from JS Bundling and Merge - specify particular URLs that shouldn't be merged or minified. Start each URL or part of the URL from new line.
bin/magento setup:static-content:deploy
in the console after any changes in this block of settings have been made.
Merging CSS Files works the same way as merging JS files.
Merge CSS Files in Admin Area - set No to forbid CSS files merging in the admin area. It won't affect your Goggle rating.
Exclude URLs from CSS Merge if needed.
Minifying CSS Files works the same way as minifying JS and HTML.
If you set Defer Fonts Loading to Yes, the browser will load the page with system fonts and replace them with your fonts when they are loaded. It makes store pages load faster.
bin/magento setup:static-content:deploy
Defer Fonts for - choose the particular devices for which the fonts should be deferred.
You may exclude some fonts from deffering in the Do Not Defer Fonts That Contain option.
As in the JS tab, you can also Move Print CSS Files to Page Bottom to make your page render faster.
Flat Tables allow storing all the information about a category or a product. Such tables help to shorten the query in the database.
A powerful feature of HTTP/2 represents the ability of the server to send multiple responses for a single client request. That is, in addition to the response to the original request, the server can push additional resources to the client, without the client having to request each one explicitly.
Before enabling the option, the server needs to be configured correspondingly for the proper work of the functionality. Please, follow the steps below to configure the server you’re using.
Please, add the following changes to the configuration file which is responsible for Magento:
1. Specify http2
flag for listen
parameters
2. Add http2_push_preload on
; to enable pushes (it should be under server
scope)
3. Specify max pushes per request in http2_max_concurrent_pushes 50
server { listen 80; listen [::]:80; listen 443 ssl http2; <-- Add http2 flag listen [::]:443; http2_push_preload on; <-- Enable preload http2_max_concurrent_pushes 25; <-- Setup max pushes per request ...
1. First, you need to enable the HTTP/2 module.
sudo a2enmod http2
2. Then edit your Apache virtual host file. If you enabled HTTPS with Let’s Encrypt, then the SSL virtual host is created as a separate file ending with le-ssl.conf
.
sudo nano /etc/apache2/sites-enabled/your-site-le-ssl.conf
3. Put the following directive after the opening <VirtualHost *:443>
tag.
Protocols h2 http/1.1
4. Save and close the file. Then restart Apache for the changes to take effect.
sudo systemctl restart apache2
unset resp.http.Link
Now we can proceed to extension settings.
Enable Server Push - enable the option to activate server push.
Asset Types to Server Push - specify the files that will be used for the push.
Exclude URLs from Server Push - provide particular URLs to exclude from the push.
In this tab you can enable some additional settings to make your webstore perform better.
Sign Static Files - activate the option to make the browser automatically update cached values once they are changed.
Asynchronous indexing - enable to distinguish traffic patterns on the database level to avoid conflicts between read and write operations. Order data is placed in a temporary storage and moved to the Order Management grid with no accidents.
Switch to this tab to configure the automatic image optimization using various flexible settings. The extension allows you to optimize JPEG, PNG and GIF images.
In this tab, you can activate the integration with the SpeedSize™ functionality for neuroscience media optimization. To learn more about SpeedSize™, please check here.
Public Key - insert the key generated on the SpeedSize side.
CDN - specify CDN.
Expand the General Settings tab to configure the main settings.
Enable Multi-Process Generation - select Yes to speed up images optimization.
Number of Parallels Processes - specify the number of processes to be performed at once. The more parallel processes are set, the faster the image optimization process is, as well as the higher is the server load.
Image Resolutions Library – Choose the library to use for creating image resolutions during Smart Optimization. The choice of library affects the speed of image optimization. GD2 is the default library, while using the Imagick library can speed up the optimization process, especially for large product catalogs.
Process Images per Request - enter the number of images you want to be shown instantly, per one request.
bin/magento amasty:optimizer:optimize -j 4
Moreover, you can specify the particular pattern ( i is the id of the pattern):
bin/magento amasty:optimizer:optimize -j 4 -i 2
Optimize Images for Enabled Products Only - enable this option if you want to create smaller copies for the images of enabled products only. It helps to save extra space on your server and speed up optimization.
WebP Compression Quality - set the required compression quality for WebP images (from 50 to 99).
AVIF Compression Quality - specify the desired compression quality for AVIF images. The quality level can be adjusted on a scale from 0 (worst quality, smaller file) to 100 (best quality, larger file).
AVIF Encoding Speed - configure the speed of the AVIF encoding process. The speed can be adjusted on a scale from 0 (slow, smaller file) to 10 (fast, larger file).
To learn more, click the following link.
Expand the User Agent tab to adjust settings for image loading according to the customer's browser user agent.
Set the Use User Agent for Loading Images to Yes to enable fetching appropriate image sizes based on the user agent data, obtained from the browser.
In the Ignore Images that Contain you can specify certain images to be excluded from the loading based on the user agent info. Such images will be delivered on the users' devices in the original size.
Choose the strategy of image optimization. Here you can implement the options selected in the New Pattern for Image Optimization settings section.
Image Replace Strategy - select the suitable strategy for image optimization:
* Choose None if you don’t need to optimize images;
* Choose the Smart Optimization strategy to automatically replace all existing images with lighter alternatives in either AVIF or WebP format. When this strategy is enabled, images will be replaced with AVIF format versions. If the user's browser doesn't support the AVIF format, images will be replaced with WebP format alternatives (WebP and Image Resolutions strategy). You can access a list of browsers that support the AVIF format here;
* Choose SpeedSize to optimize all existing images with the SpeedSize™ functionality. Please note that this strategy will work only if the correct CDN and Public Key in the SpeedSize Settings section are specified.
Ignore Images that Contain - specify particular images that should be skipped.
Support Third-party Image Attributes - you can replace images generated by third-party lazy load extensions by specifying the required attribute. Example: <img src=“placeholder-image.png data-src=“original-image.png”/> In this case 'data-src' - it's a third-party attribute, so you need to prescribe it in the field if you want images with this attribute to be replaced with WebP format.
Additionally, you can adjust the optimization for particular store pages separately. The settings are the same as above.
In this tab, you can allow automatic image optimization.
Automatically Optimize Newly Uploaded Images - set to Yes to automatically optimize all images newly uploaded to the folders for which the Add Folder to Automatically Optimization setting in the pattern settings is set to Yes.
Clear Images Folder - the Clear WebP Images Folder / Clear Avif Images Folder/ Clear Mobile Images Folder / Clear Tablet Images Folder buttons delete the optimized files from the pub / media / amasty / folder_name folders, depending on which button is pressed. It is used if the previously selected optimization settings were inconvenient to use and there is a need to re-generate the queue and re-optimize the images.
This extension is used to load images only when they become visible, which makes pages load faster. Proceed to the Lazy load tab to enable the fucntionality.
Enable Module - set to Yes to activate lazy load functionality.
If you have Image Optimizer installed, you will be able to configure the user agent for lazy load functionality. Expand the User Agent tab to adjust settings for image loading according to the customer's browser user agent.
Set the Use User Agent for Loading Images to Yes to enable fetching appropriate image sizes based on the user agent data, obtained from the browser.
In the Ignore Images that Contain you can specify certain images to be excluded from the loading based on the user agent info. Such images will be delivered on the users' devices in the original size.
Use Lazy Loading Images - set to Yes to make off-screen images load only when a customer scrolls to them. It prevents pages full of images from lagging.
Lazy Load Script - you can choose between 4 lazy load scripts: jQuery Lazy Script, Native JS Lazy Script, Vanilla Lazy Script, and Lozad Lazy Script. We recommend trying all of them to choose one that fits your system best.
You can decide whether to request the preload of Magento 2 key images or load them from scratch when they happen on screen. Decide how many images to load by setting Preload Images Number.
Enable SpeedSize - set Yes if you want to enable SpeedSize for lazy load (for all pages at once).
Desktop Preload Images Number - set the number of images to be pre-loaded on the page from the start. You can also assign a specific number of images for tablet devices with the Tablet Preload Images Number and for phones with the Mobile Preload Images Number fields.
Ignore Preload Images that Contain - specify the images (their classes) that should be excluded from preloading.
Ignore Images That Contain - specify the images that should not be optimized.
Add Aspect Ratio Styles to Image Tags - if enabled, the aspect-ratio styles will be added to lazy loaded images based on their dimensions. It helps you to display images correctly even when only image width or height is specified.
Add to Images that Contain - specify particular images or the pattern to which the aspect ratio style should be added.
<img class="testImage myimage" src="http://site.com/1.png"/>
OR
<img src="http://site.com/myimage.png"/>
.
Please note that when the Use User Agent for Loading Images setting is set to No and the Preload Images setting is set to Yes, the following features will be available:

All other tabs of this block have the same structure, but you can specify the settings for particular site pages. Thus, you can select the most suitable type of optimization for each store page.
Save the configuration.
Pro and Premium extension versions include AMP extension. The collaboration of these modules lets you create accelerated mobile pages and use Webp image format for them, which significantly improves mobile score.
To configure the AMP component, proceed to Stores → Configuration → Amasty Extensions → AMP.
Expand the General tab.
Choose the types of pages for which the AMP versions will be generated.
Open Accelerated Mobile Pages - if Always option is chosen, users on mobile devices will be invariably redirected to AMP version of the page. If you select From AMP Google results only, AMPs will be available only via links on Google search results pages (in that case the user will stay on AMPs until he/she reaches non-AMP page).
These settings will allow to precisely configure the optimization pattern for folders.
Navigate to Content → Image Optimizer → Image Folder Optimization Settings. To create new set of rules, please click on the Add New Pattern button.
All configured patterns will be displayed in one handy grid. You can manage them any time you need just in a few clicks.
Run Optimization - click this button to optimize selected folders images.
php bin/magento amasty:optimizer:optimize
As you click the Add New Pattern button, a new Image Optimization Settings page will expand.
Set the Enabled switch to Yes to allow this set of configurations.
Title - enter the title of the configuration set to easily distinguish numerous configs in the grid.
Folders for Optimization - click on the folder name to include it in the list of folders that will be optimized.
Add Folder to Automatic Optimization - set to Yes to automatically optimize all images newly uploaded to the folders selected for optimization.
Create Image for Mobile/Tablet - set the corresponding switch to Yes to automatically create appropriately sized images for various displays. All newly created copies will be saved on your website server, so check in advance if you have enough disc space.
Resize Algorithm - select the algorithm according to which the images will be compressed:
Create AVIF Copy - select Cavif to generate an AVIF format copy for every image.
Create Webp Copy - choose Cwebp to create a copy for every image in the WebP format.
sudo apt-get install webp
For a specific setup with versioning, use this guide.
Create Image Dump - set to Yes to to store original images in the pub/media/amasty/amoptimizer_dump folder. It allows collect all the original files in one place and easily update them in case the settings are changed.
JPEG optimization tool - set the way to optimize JPEG images:
PNG optimization tool - select optipng to optimize PNG images.
GIF optimization tool - choose gifscale to compress GIF files.
Click on the Save button to preserve the settings.
The Premium version includes some unique features to improve store speed.
Since JS merging creates one huge file, for particular stores it may affect some pages on specific devices. The Premium version provides more flexibility - you can adjust merging for any device to achieve maximal effect.
To adjust the option, navigate to Google Page Speed Optimizer → JavaScript and enable the Merge JavaScript Files feature.
The Pro version has an option for automatic image optimization - all new images are optimized as soon as they are uploaded. But for some stores it is necessary to delay this process, e.g. run optimization at night, when the number of visitors is minimal. The Premium version offers Cron image compression so that the optimization could suit your personal working flow.
To set up an optimization schedule, proceed to Image Optimizer → Automatic Optimization of the Newly Uploaded Images and choose the required option in the Automatically Optimize Images dropdown.
bin/magento amasty:optimizer:optimize
To provide customers with the extra fast and handy shopping flow, the Premium version includes AJAX Shopping Cart extension. If enabled, shoppers are able to add and manage products in a shopping cart without redirects and page reloads.
Navigate to Stores → Configuration → Amasty Extensions → AJAX Shopping Cart.
Enable or disable the extension in Enable Ajax Shopping Cart.
Enable flying image effect: With this setting, you can activate and deactivate nice looking visual effect.
Show the Product Qty Added to the Cart on the Product Listing: Enable the option to highlight the products that have already been added to the shopping cart. With mouse hover over the product, the number of items added to the cart appears.
Add Products to Compare with AJAX: Enable the option to let customers add products to Compare without page reloading. This will fasten the process and make it more convenient.
Add Products to Wish List with AJAX: Set the option to Yes to eliminate page reloading when customers add products to Wish List.
Show a Mini Cart once Item is Added: Enable the option to Show a Mini Cart instead of a Confirmation Pop-up after an item is added to the cart.
You can also find this functionality in the Premium version only. Infinite scroll lets your visitors browse the catalogs without page reloads, as the content is loaded and displayed as soon as a customer reaches the end of the catalog page.
To get access to the infinite scroll settings please go to Stores → Configuration → Amasty Extensions → Infinite Scroll
Loading Type - choose from the available loading styles.
See the full list and each type specifics below:
Number of Automatically Loaded Pages - Enter the number of pages a user needs to scroll before 'Auto mode' applies. This setting is only available for Combined loading types: Combined - automatic + button and Combined - button + automatic.
Let's say, you set the number of automatically loaded pages as 4.
In the case of the Combined - automatic + button scenario, a user will see the first 4 pages similarly to a long one-pager. Then, to load the 5th, 6th, 7th, etc. pages, the user will need to press a 'Load More' button every time to load the page.
However, with the Combined - button + automatic user will be asked to press a 'Load More' button only once - between the 4th and 5th page.
Display Page Numbers - Choose 'Yes' to display the pages separator with numbers. While scrolling down the list of products you will see the line separator with the page number. Select 'No' to deactivate the separator and have the plain catalog list.
Page Numbers Style - Choose the style of page numbers from the list.
AJAX Progress Image Path - Insert the path to your own loading theme to customize your website. Choose what kind of loading wheels fits your web store layout.
You are able to add the compatibility with 3-rd party extensions which use AJAX. It can be done with the usage of the following sample:
<?php class Test { /** * @var \Magento\Framework\DataObjectFactory */ private $dataObjectFactory; /** * @var \Magento\Framework\Event\ManagerInterface */ private $eventManager; public function __construct( \Magento\Framework\DataObjectFactory $dataObjectFactory, \Magento\Framework\Event\ManagerInterface $eventManager ) { $this->dataObjectFactory = $dataObjectFactory; $this->eventManager = $eventManager; } public function execute() { $someHtml = '<div><img src="test.jpg">...</div>'; $data = $this->dataObjectFactory->create( [ 'page' => $someHtml, // \Amasty\PageSpeedOptimizer\Model\Output\LazyLoadProcessor::PAGE_CONFIG keys 'pageType' => 'catalog_category_view', // optional. Example of configs // \Amasty\PageSpeedOptimizer\Model\Output\LazyLoadProcessor::prepareLazyConfig 'lazyConfig' => [ ] ] ); //if Amasty PageSpeedOptimizer is not installed output page will be the same $this->eventManager->dispatch('amoptimizer_process_ajax_page', ['data' => $data]); $someHtml = $data->getData('page'); return $someHtml; } }
When using AJAX scroll extensions, you can also convert images to WebP format without using Lazy Load. Please use the code below to achieve this:
$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $dataObjectFactory = $objectManager->create(\Magento\Framework\DataObjectFactory::class); $eventManager = $objectManager->create(\Magento\Framework\Event\ManagerInterface::class); $data = $dataObjectFactory->create()->setData( [ 'page' => $resultHtml, 'lazyConfig' => [ 'is_lazy' => false ] ] ); $eventManager->dispatch('amoptimizer_process_ajax_page', ['data' => $data]);
To make Varnish compatible with the WebP functionality, you need to customize the Varnish configuration. Also, now the extension supports WebP for Safari 14.
To add WebP images support for users who have never visited the site using Varnish, you need to change the Varnish defaul.vcl
configuration file.
Follow the steps below:
1. Find the vcl_hash
subroutine
2. Add the code:
# Amasty Google Page Speed Optimizer device detection and cache separation mechanism if (req.http.cookie !~ "X-Magento-Vary=") { call device_detect; if ((req.http.X-Amasty-Accept-Avif || req.http.X-Amasty-Accept-Webp) && req.http.X-Amasty-Device) { hash_data(req.http.X-Amasty-Accept-Avif); hash_data(req.http.X-Amasty-Accept-Webp); hash_data(req.http.X-Amasty-Device); } }
3. Add a new subroutine using this code:
sub device_detect { unset req.http.X-Amasty-Accept-Webp; unset req.http.X-Amasty-Accept-Avif; unset req.http.X-Amasty-Device; if (req.http.Accept ~ "image\/webp" || req.http.User-Agent ~ "(?i)(\biPhone|\biPod|\biPad|\bMacintosh).*Version\/(1[4-9]|[2-9][0-9])" || req.http.User-Agent ~ "(?i)Edg|Firefox|Chrome|Opera" ) { set req.http.X-Amasty-Accept-Webp = "true"; } if (req.http.Accept ~ "image\/avif" || req.http.User-Agent ~ "(?i)(?!.*Edg)(Firefox|Chrome|Opera)" || req.http.User-Agent ~ "(?i)(\bMacintosh).*Version\/(1[6-9].[4-9]|1[7-9]|[2-9][0-9])" || req.http.User-Agent ~ "(?i)(\biPhone|\biPod|\biPad).*Version\/(1[6-9]|[2-9][0-9])" ) { set req.http.X-Amasty-Accept-Avif = "true"; } if (req.http.User-Agent ~ "(?i)Mobile") { set req.http.X-Amasty-Device = "mobile"; } elsif (req.http.User-Agent ~ "(?i)Tablet") { set req.http.X-Amasty-Device = "tablet"; } else { set req.http.X-Amasty-Device = "desktop"; } }
4. Reload Varnish.
