About Page Speed Image Optimizer SEO

Shopify Page Speed Optimization

40% of people will abandon a website if it takes more than 3 seconds to load. That’s why every merchants should optimize their website speed and have a powerful caching system at its core. A fast-loading site is more likely to rank higher in search engines (SEO), keep visitors stay longer, and increase conversion.

Swift is an advanced speed solution for Shopify store owners which offers an innovative approach based on powerful tools including Google Lighthouse, PageSpeed Insights, GTMetrix, Pingdom & Core Web Vitals metrics to speed up your store performance

Advanced Shopify Image Compression to improve page speed

  • Using Smart Lossy compression technology to compress & optimize images, which minimizes large image size without reducing their quality. Lighter means faster.
  • We keep backups of each image we compress, so you can restore them quickly with a click.

Auto Optimize process with new images & files to save tons of time

  • Instead of manually optimizing images & files, our auto-optimization service allows you to optimize new images & files fully automated that you just upload to your store, so you can focus more on your sales & business.

Make your files lighter with minification & JavaScript (JS) deferral

  • Swift minifies JS, HTML, inline critical CSS, font caching, theme asset files to reduce page size & speed up store's initial load time

Media files loaded only when needed

  • With smart Lazy Load Images technology, Swift automatically defers the loading of images, leaving them ”off-screen” until visitors need them.
  • Lazy-loading is a brilliant way of optimizing both perceived & real performance.

Speed up next-page navigations with preloading

  • Analyzing &predicting what page/product a visitor is going to visit next, or which link is most likely to be clicked. Then Swift preloads those contents in advance & delivers the page right after it is requested. Therefore, users would experience a very short waiting time & lower bounce rates.
  • This smart technology makes store faster 600 milliseconds on average from page loading time. By using AI, Swift provides the level-up prefetch techniques to increase 3x faster page speed than other apps.

This app seems to have improved the speed of my website by optimising images and my theme. It is a little expensive but worth the money to keep the site functioning optimally and the lazy loading seems to have been approved by Lighthouse.
