Checkout Flow Comparator
Compare one step of your checkout flow to two competitors' on SEO, UX and CRO criteria specific to checkout: trust signals, HTTPS, minimized distractions, form length.
This tool analyzes the page's HTML structure (CTAs, forms, trust signals, pricing, navigation) and its loading performance. It cannot measure a real conversion rate: that requires the analyzed site's own tracking (Contentsquare, Hotjar, GA4...), which isn't accessible on a third-party URL.

How to use this tool
- 1A checkout flow often has several steps (cart, address, payment): analyze one precise URL at a time, whichever worries you most
- 2Enter that URL and up to two competitors' on the same step
- 3Run the comparison
- 4Review which criteria pass or fail, with the advice for each
Why it matters
Checkout is the step where abandonment costs the most: every form field, every unnecessary navigation link or missing trust signal has a direct, measurable impact. This tool analyzes one precise step of the flow (the URL provided), not the whole multi-page journey: repeat it for each step if your flow has several.
A concrete example
On a typical payment page, the tool might find correct HTTPS and a reasonably short form, but no payment method logos or refund guarantee mentioned before checkout. These last-second reassurance signals are often what determines abandonment, not form length.
Frequently asked questions
Does this tool measure a real conversion rate?
No. A real conversion rate requires tracking specific to the site (Google Analytics, Contentsquare, Hotjar...), which isn't accessible on a third-party URL. The tool analyzes the page structure that correlates with conversion, without measuring it directly.
What do FCP, LCP, CLS and INP/TBT mean?
These are the Core Web Vitals, the indicators Google uses to assess a page's loading experience. FCP (First Contentful Paint) measures the time until the first visible element appears. LCP (Largest Contentful Paint) measures the time until the largest visible element appears. CLS (Cumulative Layout Shift) measures visual stability during loading. INP (Interaction to Next Paint) measures the page's actual responsiveness to interactions; TBT (Total Blocking Time) is its lab equivalent.
What's the difference between PSI, Lighthouse and CrUX?
PageSpeed Insights (PSI) is the Google API this tool uses. It combines two sources: Lighthouse, a lab test that simulates loading on a standardized device and network, and CrUX (Chrome User Experience Report), which aggregates real measurements from Chrome users who visited the page. This tool's "Mobile performance" score comes from Lighthouse. The Core Web Vitals block shows CrUX data when available, otherwise the Lighthouse lab estimate.
Why does the Core Web Vitals block sometimes show a lab estimate instead of field data?
CrUX only returns data if the page received enough Chrome traffic over the last 28 days. Below that threshold, common on lower-traffic sites or recent pages, no field data exists: the tool then falls back to the Lighthouse lab estimate, a simulated test rather than a real measurement.
Why does the indicator become TBT instead of INP in the lab estimate?
INP measures real responsiveness to actual visitor interactions: it can only be measured on real traffic, not in a lab test where no one interacts with the page. TBT is the closest lab indicator: it estimates the time the page stays blocked and unable to respond quickly to an interaction.
Why is HTTPS specifically checked here?
On a checkout flow, missing HTTPS is a dealbreaker for trust: most visitors abandon immediately if they see an insecure connection warning at the moment of payment.
My checkout flow has several steps, what should I do?
Analyze each step separately (cart, address, payment) by changing the URL entered. The tool evaluates one page at a time; it can't reconstruct an entire multi-page journey from a single URL.
Does the tool check which payment methods are offered?
No, it can't detect which payment methods are actually integrated (often loaded via JavaScript). It does check for the presence of secure payment logos or mentions in the page content, a distinct reassurance signal.
