Is Slow Speed Quietly Costing You Sales?
Storefront Speed measures how fast your store feels to real shoppers and whether that speed is costing you sales — starting with a plain-English verdict, then four Core Web Vitals graded the way Google grades, from real visitors.
- Verdict-first
- From real visitors
- Four Core Web Vitals
- Slow pages ranked by revenue
Verdict first
A plain headline before a single number
You shouldn’t need to decode a chart to know if your store is slow. Storefront Speed leads with a plain-English verdict — “Your store is fast,” “A few pages are dragging,” or “Speed is costing you sales” — so you get the answer first and the detail only if you want it.
- One plain headline that says where you stand
- The detail is there when you want it, not before
- Measured from your real visitors, not a lab machine

Fix the slow pages that actually cost you money
A slow page nobody visits isn’t worth your time. Storefront Speed ranks slow pages by the real revenue flowing through them and links each to its matching performance fix — so you spend effort where speed is genuinely costing sales. Low-traffic stores are told so plainly, never handed fake numbers.
- Slow pages ranked by the real revenue moving through them
- Each links to the matching performance fix
- Low-traffic stores are told so — no invented numbers
Common questions
Storefront Speed — frequently asked
How is this different from a Lighthouse or PageSpeed score?
Lab tools test one simulated load on one machine. Storefront Speed measures how fast your store actually feels to your real visitors — the way Google grades Core Web Vitals from field data — so the numbers reflect your real traffic, devices, and networks, not a synthetic run.
What does the verdict at the top mean?
Before any number, Storefront Speed gives you a plain-English headline: 'Your store is fast,' 'A few pages are dragging,' or 'Speed is costing you sales.' It's the one-line answer, so you know where you stand without reading a single chart.
Which metrics do you grade?
The four Core Web Vitals, each graded Good, Needs work, or Poor: Loading (LCP), Responsiveness (INP), Visual stability (CLS), and Server response (TTFB). You also see the page-load experience — the share of loads that were fast, so-so, or slow — and a loading-speed trend over time.
How do you connect speed to revenue?
Slow pages are ranked by the real revenue flowing through them, so you fix the ones that actually cost you money first — and each links to the matching performance fix. If your store doesn't have enough traffic to measure reliably, we tell you that plainly instead of inventing numbers.
