How to optimize Shopify for speed

Share

Website performance is one of the most important issues that Shopify online store owners need to solve. It affects the resource’s ability to convert users. The larger the site, the more visitors it will be able to attract. To improve SEO, performance is one of the ranking factors.

Other digital marketing promotion initiatives are also influenced by performance. This applies to both paid, email and social marketing. If a site receives a large percentage of visitors from these channels, then even a minor improvement will lead to an increase in revenue. An increase in speed for just a second can bring in profits of several thousand dollars. Therefore, providing Shopify speed optimization is an important task.

How can you increase the speed?

To do this, you need to do the following:

  • choose a light theme;
  • reduce the size of large images and compress them;
  • replace GIF files with static ones;
  • install lazy loading of images;
  • restrict third-party applications;
  • transfer tracking codes to tag manager;
  • better manage your store through Google PageSpeed ​​Insights.

Choosing a light Shopify theme

If you use a fast theme, you can immediately increase your productivity. Some variants are designed with unnecessary inflation after installation, which negatively affects speed. A light theme can improve this indicator.

Make large images smaller

Work on the dimensions, perhaps one of the best ways to increase the speed of work. Many companies post a lot of pictures on the resource. There is a good reason for this, as images are a staple in e-commerce.

A good image is a good way to improve UX and branding, but it’s important to compromise on performance. A page can have a lot of weight if it contains a lot of images, it takes longer to load. Unoptimized images can complicate the situation if their size is significantly larger than that of the rendering.

Uploading large images can cause unnecessary rendering problems, requiring potential buyers to spend more data and browser resources to view the content.

To find large sized images, use the Chrome DevTools. Right click and then click check. Go to the Network tab and refresh the page. Then sort by size to find the largest ones.

If you find images larger than 100 Kb, right-click on it on the page and check it again.

Image compression

If images are not compressed, they may not be optimized. Often times in Shopify stores there are situations where compression was not used, so images are larger than needed

By using compression, you can ensure that your resources are smaller than the original. If you need to compress, you can use a combination of the following methods:

  • Shopify apps work automatically, compress on load;
  • Optimizilla is designed for manual operation.

Replacing GIFs with static images

The use of GIFs also affects the loading speed of websites. Some of these files can be of great value because they provide an interactive interface. It is possible to improve the site in terms of UX and brand. As a rule, the size of such files is large, even one such image significantly affects the download. Several files can increase the page size by more than 10 MB, so we recommend replacing them with static images whenever possible. This will speed up the speed and save resources.

Lazy loading images

When launching a list of Shopify sites through PageSpeed Insights, it was a common recommendation to defer offscreen images. This means that all graphic resources of the store are loaded at the same time. Since many images are used, lazy loading is important in many cases to improve website speed. Pictures will be loaded as the user scrolls down the site.

If you are thinking about implementing lazy loading, Shopify has some good stuff to offer. They are available in the lazysizes library.
