Every other free tool grades how fast your page is. We grade that too — then read the page for the six things that actually decide whether a visitor buys.

Load speed

Google's own PageSpeed score and Core Web Vitals, in plain English.

CTA clarity

Is your main action visible above the fold, or buried below it on mobile?

Form friction

Every extra field costs you sign-ups; we count them.

Trust signals

Reviews, guarantees, security badges — present, or missing where it matters?

Mobile UX

Tap targets, readable text, no rage-inducing pop-ups.

Ad-to-page match

Does the page deliver what your ad or link promised?

Why not just use Google?

Google grades whether your page is fast. We grade whether it sells.

PageSpeed Insights and GTmetrix are great at one thing — speed. But a fast page that hides its Add-to-Cart, asks for eight form fields, and shows no reviews still loses the sale. Those are the leaks we surface, and speed tools can't see them.

ConvRadar page speed & UX check

✓All of the above — we use Google's own score, labelled honestly

✓PLUS the CTA, form, trust-signal, message-match & mobile-UX issues costing you the sale

✓PLUS — connect GA4 — proof against your real funnel, not a guess

We show you the likely leaks. Connect your GA4 and we prove them on your own numbers.

How it works

Three steps. About thirty seconds.

Paste your URL

Homepage, a key product page, anything public. No login, nothing to install.

We scan it

We run Google PageSpeed, take a screenshot, and read the page against 120+ conversion patterns. Results render right here — no email, no queue.

Get your score + fixes

A speed score, the screenshot, and the top likely leaks, each with a specific fix. Want every key page tied to your real funnel? Connect GA4 in ~60s (read-only).

From "likely" to "proven"

We flag the leak. Your GA4 proves it.

A page check can tell you your Add-to-Cart is below the fold on mobile. Connect your GA4 — your Google Analytics, read-only, 60 seconds — and we can tell you what it's costing you:

Your Add-to-Cart sits below the fold on mobile — so only 3.5% of phone visitors add to cart, vs 6.1% on desktop. That gap is lost sales.

Go one step further: the full conversion audit connects your GA4 and shows every drop-off across your whole funnel — not just this page — ranked by the revenue it's costing you, with the fix for each.

Questions

Straight answers.

Is it really free?

Yes. The check on this page is free with no account. Page checks you run from Claude or ChatGPT, with screenshots of your key pages, are part of Pro (30 a month); Basic gets 1 to try.

What do you do with my URL?

We fetch it once through Google PageSpeed and take a single screenshot. We don't crawl your site and we don't need a login. Your report is kept at its own link so you can come back to it, and we publish nothing without asking you first.

How is this different from Google PageSpeed Insights?

We use Google's speed score and add the things it can't see: your CTA, forms, trust signals, message match, and mobile UX — the stuff that decides whether a fast page actually converts.

Do I need GA4?

No. You get a full check without it. Connect it (read-only, 60 sec) and we can prove each flagged issue against your real funnel.

Does it work for Shopify / WooCommerce / Wix?

Any public URL, any platform. Start with your homepage or best-selling product page.

What happens after my free check?

You see your result immediately. To check more pages you create a free account with Google — about 10 seconds, no card.

The details

What is a page speed & UX check?

A page speed & UX check measures two things at once: how fast your page loads (via Google's Lighthouse/PageSpeed engine) and how well the loaded page is built to convert. Speed is measured; conversion factors are assessed against known patterns and, ideally, your own analytics.

What actually hurts conversions (besides speed)?

A buried or unclear CTA, too many form fields, missing trust signals, weak message match between ad and page, and mobile friction (small tap targets, intrusive pop-ups) — each with a plain-English "why it costs you" and a directional benchmark.

How we measure

Google PSI for speed (Measured), a heuristic read of the rendered screenshot for conversion elements (Likely), and — when GA4 is connected — validation against your real funnel.

Good, needs-work, slow — how to read your speed score

90+ is good, 50–89 needs work, under 50 is slow — in plain English, with what each band means for a real shopper. Related: the full conversion audit and more on Core Web Vitals & conversion.
