6.3 seconds to 1.8. As much as 35% more conversions.

Every page under two seconds on low-4G, guaranteed. Mtrix measures the speed your shoppers actually feel on their own phones, then shows it next to the revenue it earns — across the stores we run, that drop drove as much as 35% more conversions on the same traffic.

The speed your shoppers lived — not a lab score.

The load times your customers' own phones recorded on your live store. That's the only speed that converts, so that's the only speed we measure.

A lab scores a URL. Mtrix scores your checkout.

Your Shopify speed score and Google PageSpeed are single lab runs on one borrowed phone — useful for debugging, blind to your live traffic, and weeks stale. Mtrix is your real shoppers, today, on the pages that move money — your advertorial, your checkout, your upsell — with the dollars each slow one is bleeding.

Lab run

Your Shopify / PageSpeed score

  • One Lighthouse run on a borrowed phone — great for debugging, blind to your live traffic.
  • It folds in Google’s field data — but that field data is about 28 days stale.
  • One blended number per URL — no slicing by campaign, page type, or country.
  • No idea what a slow checkout costs you.
Mtrix

Your shoppers, your funnel, your dollars

  • Every real device, network, and city your shoppers actually use.
  • Fresh today — a regression you ship Tuesday shows up Tuesday, not next month.
  • Sliced by page type, campaign, country, and more.
  • Each slow page priced in the conversions it’s costing you.

Lab tools earn their place pre-launch. Even Google notes its lab result may not capture real-world conditions — real-user data is the only way to know for sure.

See which page — and which device — is losing the sale.

Every page gets one score and a plain verdict — Great, Needs work, or Poor — with the four metrics behind it, so it’s never a black box. Toggle Desktop and Mobile to catch the gap your phone shoppers feel, walk the funnel stage by stage, and slice by campaign, country, or device — 27 dimensions in all. You fix the page that’s actually costing you the sale, not a blended average.

Funnel stage

Checkout · Desktop 96 (Great) · Mobile 71 (Needs work) — your highest-intent page is the slow one on mobile.

Under 2 seconds on low-4G. Every page. Guaranteed.

Not “up to” fast. Not “fast on Wi-Fi.” Every page Mtrix ships loads in under two seconds on a mobile, low-4G connection — the honest worst case your shoppers hit on the train or a crowded signal. And it’s verified by your real shoppers, not a lab score — a promise the simulator-based guarantees can’t make.

SLA Verified by real shoppers

Every page we ship. Under 2.0s. Mobile low-4G. Verified by real shoppers.

Why low-4G

A weak mobile signal — on the train, in a parking lot, on a crowded network — is where shoppers feel slow the most and bail. We guarantee the hardest case, not the easy one.

If a page we ship misses under 2s on low-4G, we fix it free — before it counts against you.
