About Swift ‑ Page Speed Optimizer

Why should every merchants optimize their website speed?

40% of people will abandon a website if it takes more than 3 seconds to load. With Google Search now including Core Web Vitals as the foundation for evaluating page experience, a fast-loading site will be ranked higher in search engine (SEO) & increase conversion.

What is Swift?

Not like heatmap tools like Hotjar, Lucky Orange which help you to analyze audience, Swift is a Shopify Page Speed Optimization solution offering an innovative approach based on powerful tools including Google Lighthouse, PageSpeed Insights, GTMetrix, Pingdom to optimize commonly used apps & analytics, and speed up store performance.

Advanced Smart Lossy Image Compression technology

  • Helps to compress & optimize large image size images similar to Crush.pics. Lighter means faster!
  • Keep backups of each compressed image, so you can restore them fast with a click

Auto Optimize process to save tons of time

  • Instead of manually optimizing, auto-optimization service optimizes new images & files fully automated just uploaded to store, so you can focus more on your business

File Optimizer & lighter with minification & unused JavaScript (JS) deferral

  • Minifies JS, CSS, HTML, theme asset files to reduce page size & speed up store's initial load time, FCP, LCP, TBT

Media files loaded only when visitors need them

  • With smart Lazy Load technology, Swift automatically defers the loading of images, leaving them ”off-screen” & inline critical CSS, so they do not affect to your store speed.
  • A brilliant way of optimizing both perceived & real performance

Speed up next-page navigations with preloading

  • Not just analyze like heat map tools, Swift predicts what page a visitor is going to visit next, or which link is most likely to be clicked, then preloads those contents, font caching & delivers the page right after it is requested. Therefore, users would experience a very short waiting time & lower bounce rates
  • Makes store faster 600 milliseconds on average from loading time on Homepage speed & others. By using AI, Swift provides the level-up prefetch techniques to increase 3x faster speed than other apps using normal Preload.

I used their Swift Expert service, it is a one time cost. It clean up the unused CSS and coding and helps improve my page speed score significantly. So I don't have to hassle and do it myself which really takes time. Their response time is real quick and always come back to me for follow up. Highly recommend for their expert service!
