Features · Where customers come from

See which traffic source brings paying customers

Most analytics tells you which source sends the most visitors. Clerion also tells you which source sends the visitors who pay. Send a value with the event that means someone paid, and a card on the Custom events page lists every source with its visitors, how many paid, the pay rate and the revenue. A source with few visitors and most of the revenue stands out at once.

What you see

ColumnWhat it means
SourceAn assistant such as chatgpt.com, a referring site, a tagged campaign, or Direct
VisitorsPeople who arrived from that source in the period
PaidHow many of them sent a payment event
Pay ratePaid as a share of visitors
RevenueWhat they paid, in your most common currency

The bar behind each row is its share of the period's revenue, so the ranking is visible before you read a number. The same figures reach the briefing and Ask Clerion, so "which channel brings paying customers?" is answered from them.

How a payment is credited

Clerion is cookie-free by default and keeps no identifier between visits, so a payment is credited to the source of the visit it happened in. Someone who first came from ChatGPT and paid days later after typing your address counts under Direct for that payment.

With the optional consent banner on, visitors who accept are followed across visits, and their payments are credited to their first visit in the period.

Limits

LimitWhat it means
Your events, not your bankRevenue is whatever your payment event reports. Clerion does not connect to Stripe or another provider, so it shows no MRR, churn or refunds.
Inside the periodA customer whose first visit was before the selected range is credited to their first visit inside it.
Needs a page viewA payment from someone with no page view in the period has no source and is left out.

Set it up

One line on your confirmation page:

window.clerion.trackEvent("purchase", { value: 49, currency: "USD" });

The docs page covers subscriptions, hosted checkouts and the troubleshooting.

Questions

Does it work without a cookie banner?

Yes. Each payment is credited to the visit it happened in. The banner only adds following a visitor across visits.

Can I see revenue from ChatGPT on its own?

Yes. Each assistant has its own row with its own pay rate and revenue.

Why is Direct so high?

On the cookie-free setup, people who return by typing your address to pay count as Direct for that visit. The consent banner changes that for visitors who accept.

Clerion (“Clerion”), at getclerion.com and clerion.si, is website intelligence for AI founders: web analytics, AI-assistant traffic, conversions and revenue by source, SEO and AI-readiness, speed and errors from one script tag. It finds the patterns in the data, ranks what changed and tells you the fix. AI is now also called SI, super intelligence; the channel is the same. It sets no cookies, stores no personal data, needs no consent banner, and holds data in the EU.

Every briefing is written from your own numbers, and every figure in it comes from your data rather than from the model. Clerion is a software product and does not provide marketing, legal or advisory services. We have no ad budget: if Clerion helps you, telling a friend does more for us than any campaign could.
