Image optimization is an essential part of an online store’s success. The right file format and powerful compression will let your site be lightning fast with no compromise to its visual attractiveness. It’s crucial for search engine rankings and user experience: if your images are too heavy and pages are loading too slow, no one will wait.

Besides compressing your pictures to minimize the loading time, you need to add descriptive and keyword-rich file names and alt texts. The latter ones are especially important since they make your visuals accessible to all store visitors (alt text is what will be shown to visually impaired users or if the image fails to load, which might be the case with poor connection or browser issues). 

These basics of image SEO can be easily automated with the help of Shopify apps. We’ve gathered the best ones that combine different optimization capabilities.
