Shopify Pagespeed Audit

Paste your store URL and we'll check whether your theme or an installed app is using pagespeed-optimization hack code — the kind that fakes Lighthouse scores while real customers still see a slow store.

Is Your Shopify Speed Score Real or Fake?

Many Shopify store owners install "pagespeed optimizer" apps that promise instant speed improvements. But these apps often inject hack code that tricks PageSpeed Insights while your real customers experience slow loading times.

How Fake Speed Apps Work

These apps detect when PageSpeed Insights (or other speed testing tools) visit your store. When detected, they serve a stripped-down version of your page — hiding JavaScript, blocking third-party scripts, or even serving a completely blank page. This creates an artificially high score that doesn't reflect real user experience.

Meanwhile, your actual customers still load the full, unoptimized store. The result: you see a 95+ PageSpeed score, but your real mobile load time is 6-10 seconds.

How Our Audit Detects Fake Optimization

Our free audit uses a two-point detection system. First, we fetch your page from a server — where hack code typically blocks or strips content for non-browser visitors. Then we compare this with what Google PageSpeed sees. If there's a discrepancy, we know something is manipulating the results.

We also check for known hack signatures: the transparent 99999×99999 SVG trick, script-blocking libraries like Yett.js, and document.write() patterns that empty the page for bots.
