Image Optimization

It is a normal practice for an ecommerce store to have plenty of high-quality images since they attract customers and make your products more appealing. However, a high quantity of pictures on a web page occupies large amounts of internet bandwidth and slows down your website. Consequently, it spoils user experience and search engine rankings and negatively effects sales. That’s why it is so important to optimize images to improve your website’s overall performance and let a browser deliver your web pages content faster with fewer bytes to download.

The best solution in regards to the mentioned above issue is using a third-party module that can automatically compress images. Amasty Google Page Speed Optimizer for Magento 2 provides such functionality, allowing store owners to reduce the size of the product and other pictures without losing their quality. It is possible to set the level of compression for JPEG optimization and apply it to selected folders with images.

The module supports the most widely used image formats like gif, jpg, and png. Besides, the Amasty tool allows creating a copy of an image in the WebP format and sending your pictures directly in this format to the browsers that support it. This way, you can keep the high quality of visual content on your website pages, at the same time increasing the speed of your store. As a result, you get a lightning-fast website, which improves customer experience and leads to higher conversions and sales.

Another possibility provided by the Magento 2 module related to image optimization is Lazy Load. Enabling this function allows postponing an off-screen image loading until a user scrolls to a page with the image. This feature is especially useful for long catalog pages as it prevents a page from lagging. Magento admins can leverage advanced settings to configure image optimization on the homepage, category, product, and CMS pages separately.

Furthermore, you can leverage the image resize feature to create multiple copies of a single image in different sizes. The extension will use pictures in smaller resolution for mobile and tablet devices. It will improve page load speed and help your website get higher rankings in Google.

One more beneficial feature you get with the Google page speed optimizer Magento 2 module is User Agent. By leveraging this function, you can set optimization features for mobile, tablet, and desktop devices separately. Besides, User Agent allows applying the Lazy Load, WebP, and Resize features at the same time. This way, frontend users will always see properly optimized images without time lags no matter which device they are using to browse your website.

HTML, JS, and CSS Optimization

Besides reducing the image size, you should pay attention to optimizing other resources on your website, such as code structure. The Amasty Google Page Speed Optimizer extension provides necessary settings that can be quickly configured to compress HTML, CSS, and JS files automatically.

One of the features related to code compression available with the Magento 2 website optimization module is file minification. Compressing the size of your JavaScript, CSS, and HTML files will significantly speed up your website and increase overall performance. The files are minified by removing some elements which are not important for a browser to read your code. These elements include line breaks, comments, tabulation, white spaces, and unnecessary characters. This way, you can compress the size of an original code by 10 – 20% without any negative influence on the code itself and make your web store pages load much faster.

Moreover, the Magento 2 page speed optimization module offers advanced JavaScript bundles builder that allows bundling JS files to reduce the size of a page in kb. This way, you can make pages loading even faster, which will positively affect Google rankings of both desktop and mobile website versions.

The module’s functionality also allows merging CSS and JavaScript files into one. It allows reducing the number of server requests, which makes web pages load faster. This improvement is also vital for customer experience when they browse your website pages since they can view all the content in a matter of seconds.

Another option for decreasing page loading time is moving JavaScript to the bottom of the page. This technique is also known as a defer parsing and is applied to eliminate render-blocking JS files. With this functionality, your customers will see a web page content much faster since it is loaded before the JavaScript code.

Other Features

The Amasty Google Page Speed Optimizer extension for Magento 2 offers some other advanced features that enable users to optimize website speed and enhance web pages performance on an ecommerce store. The module allows using asynchronous indexing to avoid conflicts between the read and write operations on the database level. For this purpose, order data is indexed asynchronously and safely transferred to the order management grid from temporary storage.

Also, you have an option to sign static files, which allows preventing loading old versions of your website pages from the cache. By enabling the function, a browser will automatically update cached JavaScript and CSS files if they were modified. Moreover, you can use flat tables for storing information about products and categories. It will make database queries shorter and improve website performance and, consequently, customer shopping experience.
