The Black Friday Truth Test · 1,000,000 events · €0

You pay for every click.
You decide on half.

In our experience with clients, between 40% and 60% of traffic doesn't accept cookies, and of those who do, 40% don't accept on the first pageview. Here is the deal for CMOs and eCommerce managers. Run Sealmetrics next to GA4 on your own site, and reconcile both against the orders your store actually took. You will know which channels are selling for real before Black Friday. Claude installs it, there is no card, and you keep GA4. At Incapto, GA4 missed 29% of visits; at Palladium, 35% of GA4 bookings had no channel.

THE QUESTION

Explain to me how you make your campaigns profitable when part of your traffic never reaches your report, and part of the sales you do see are filed under the wrong channel, or under none.

Rafa Jiménez · Founder, Sealmetrics

TEAMS ALREADY MEASURING WITH SEALMETRICS

01 / THE EVIDENCE · INCAPTO

The orders were real.
GA4 saw 71% of the visits behind them.

Incapto ran GA4 and Sealmetrics side by side on its Shopify store for 48 days. First it reconciled Sealmetrics against real orders. Then it compared the two tools.

SEALMETRICS VS SHOPIFY · ONLINE STORE
96%

of real Shopify orders recorded

97%

of real revenue recorded

14 JUN — 31 JUL 2026

Visits recorded over the same 48 days

GA4157,844
Sealmetrics222,345

64,501 visits GA4 never saw

GA4 recorded 29% fewer visits than Sealmetrics, and 45% fewer pageviews: the visits it misses browse twice as deep as the ones it records.

“Consent Mode left us with a structural blind spot: we knew there was traffic we were not seeing, but we had no way to size it.”

Rosa TomàsB2C Acquisition Manager · Incapto
Read the full Incapto case

Reconciliation covers Shopify Online Store only, excluding subscriptions, physical retail and manual orders. Sealmetrics reconciles 95.71% of orders and 96.53% of revenue. The visit window and the channel window are analysed separately. These are measurement differences, not incremental sales.

Dreamplace HotelsCASE FILE

Dreamplace checks Sealmetrics against its CRM and uses the gap to move budget between Meta and Google.

“The value is in optimising budget and investment. You shift toward a channel or strategy you were not seeing before.”Eduardo Martin · Dreamplace Hotels

Palladium found 40% of inbound traffic without source or medium and rebuilt its Display decisions on a neutral measurement layer. Display Cost-per-Search improved 165%.

TWO THINGS OUR CLIENTS FOUND

How Palladium improved Display Cost-per-Search by 165%How Incapto found that its best-converting traffic was the traffic that accepted cookies least

02 / THE SALES YOU ALREADY MADE

Every sale you record,
filed under the channel that closed it.

Sealmetrics attributes each conversion to the traffic source of the session in which it fires, last click, on the complete dataset rather than on the visitors who accepted a banner. No Cross-network bucket that hides part of your paid spend, and no unknown-origin line you cannot decide on: at Incapto that line was 14% of visits in GA4 and 0.3% in Sealmetrics.

Revenue by channel, campaign and landing page

The report that decides your media budget, calculated on the traffic that actually arrived.

The whole funnel, in aggregate counts

Visit, product, cart, checkout, purchase: step counts by channel, so you see where each channel's buyers drop.

Fresh data, Black Friday included

Hits usually reach your reports in under two minutes, with no sampling, and each day is complete before 6 AM. You adjust during the campaign, not the week after.

Measurement is aggregate and anonymous: no visitor identifiers, no cross-device journeys, no multi-touch model. Last click on complete data, and a number you can reconcile against your orders.

03 / THE OFFER

The first million events
are on us.

You have one million events to see the reality of your business. What you were looking at until now was something else. Open the Agentic account: the full measurement architecture, no card, nothing to cancel.

No card. Nothing to cancel. The only thing you spend is the few minutes the installation takes.

NO CREDIT CARD · NOTHING TO CANCELAn event is a recorded interaction: a pageview, a click, a purchase. One visit generates several. A million events is enough to run a real comparison.

WHY WE GIVE THE FIRST MILLION AWAY

Because the reconciliation sells better than we do.

Our published clients started the same way: Incapto checked Sealmetrics against its Shopify orders, Dreamplace against its CRM, Palladium against GA4. We would rather you see the gap on your site than read about it on ours. If there is no gap, you owe us nothing and you will have learnt that your analytics is fine.

THE GUARANTEE

Your till is the guarantee.

Sealmetrics reconciles against orders your store actually took, not against our word. At Incapto that was 96% of orders and 97% of revenue. If you do not see more traffic and more sales with a channel than in GA4, you have not paid a cent and there is nothing to cancel.

Self-service, documentation support. Requires an MCP-capable assistant; its subscription is not included.

BONUS 1 · THE INCAPTO METHOD

Reconcile against the till,
then read the difference.

Nothing here depends on trusting one vendor over another. The method is to anchor both tools to a number that is not produced by either of them — the orders the store actually took — and then inspect where the two diverge.

01

Take the real order total

Use the eCommerce platform's own orders for the period. Online store only: exclude subscriptions, physical retail and manual admin orders, which have no web visit behind them.

02

Measure both tools in parallel

Leave the existing analytics in place and run the second measurement layer over the same days on the same site.

03

Reconcile before comparing

Check each tool against the order total first. A tool that cannot match the till is not a reference for anything else.

04

Break the gap down by channel

The loss is not uniform. Find which channels it concentrates in, because those are the ones whose budget is being decided on the wrong number.

05 / START FROM CLAUDE

Three sentences to Claude.
Then the pixels are yours.

No form, no dashboard, no sales call. Install the Sealmetrics extension in Claude Desktop and tell it what you want: it creates the account, provisions your site and generates the pixels. No card and no existing account needed.

  1. 01

    Install the Sealmetrics extension in Claude Desktop

    Download sealmetrics.mcpb. In Claude Desktop open Settings, then Extensions, drag the file in and click Install. Leave the “Sealmetrics API key” field empty.

    Download the Claude Desktop extension
    CODEX · ~/.codex/config.toml
    [mcp_servers.sealmetrics]
command = "npx"
args = ["-y", "@sealmetrics/mcp"]

    Codex and other MCP clients run the same package locally.

  2. 02

    Tell it to create your account

    Paste the prompt with your domain. Claude shows you the terms and asks you to accept them, asks for your email, then provisions the account and the site. A link to set your password arrives by email.

  3. 03

    Tell it to generate your pixels

    It returns the tracking code for your site. Ask for the purchase conversion too. From here it is up to you.

COPY, ADD YOUR DOMAIN AND SEND TO CLAUDE

Create my free Sealmetrics account for [your domain], provision the site, generate the tracking pixels for pageviews and purchases, and tell me how to install them.

Once the pixels are live, ask Claude: “Confirm Sealmetrics is receiving visits from [your domain].”

Creating the account from Codex or another MCP client? Read the Agentic package guide

From here it is up to you

a

Push them to your site through GitHub

If Claude has access to your repository, ask it to open the pull request with the pixels in place.

b

Add them to GTM through a GTM MCP

If you run a Google Tag Manager MCP, ask Claude to create the tags and publish the container.

c

Copy and paste into GTM yourself

Create a Custom HTML tag on All Pages. The pixel stores and reads nothing on the device; whether it can fire without your consent trigger depends on your configuration and your national authority's criteria, so confirm it with whoever owns privacy.

06 / WHAT'S NEXT

Next: measure your traffic
with your AI assistant.

Once the account exists, connect Sealmetrics to the assistant you already use by following only these steps, with no configuration files to touch. Ordered from easiest to hardest.

HOW TO KNOW IT WORKS

Ask your assistant this question. It must answer with your real data.

How did my traffic do this week?

A NOTE FROM THE FOUNDER

If you have read this far and still have not opened the account, I know you are not going to buy Sealmetrics today. Fine. But I have to tell you: Sealmetrics is a cannon.

Our pixel is 132 times lighter than GA4's and 155 times lighter than Adobe's. That is why it records visits the heavy scripts drop before they fire (on a European media site, 25% more pageviews than Adobe, with Adobe firing without a consent gate), why it records the sales that happen with no banner in the way, and why it assigns each one to the channel that closed it.

There is a free package. Try it. You lose nothing. Compare. One: tell Claude to install the MCP. Two: tell it to create your account. Three: tell it to generate your pixels. From there it is up to you: have it push them to your site through GitHub, have it add them to GTM if you run a GTM MCP, or copy and paste them into GTM yourself and decide with your privacy lead whether the tag waits for the banner.

Rafa JiménezFounder, Sealmetrics

Clear before you start.

Is it really free, with no card?

Yes. We gift you the first million events: the Agentic account is free up to one million events in total over the life of the account, with no credit card and nothing to cancel. You need an MCP-capable assistant such as Claude; its subscription is separate.

What is an event?

A recorded interaction on your site: a pageview, a click on something you track, an add-to-cart, a purchase. One visit generates several events. The allowance is counted in human events, the same unit as the paid plans. For a mid-sized store that is weeks of measurement, enough to reconcile against your orders and read the difference by channel.

Do I have to remove GA4 or Matomo?

No. Keep it and run Sealmetrics in parallel on the same site for the same days. Then reconcile both against the orders in your store or CRM. That reconciliation, not our word, is the comparison.

Does the pixel need consent?

It writes nothing to and reads nothing from the device: no cookies, no local storage, no fingerprint. ePrivacy Article 5(3) is about storing or accessing information on the device, which is why many deployments can run without a consent banner; whether yours can depends on its configuration and on your national authority's criteria. Sealmetrics is designed for GDPR from the architecture up, self-assessed, not certified, with visitor data processed in Dublin and a DPA on every plan.

What exactly is the Black Friday offer?

Contract a Growth or Scale plan before 27 November 2026 and your account carries the Enterprise SLA, 99.9% availability with service credits and priority support, until 6 January 2027, at your plan's price. Fresh, unsampled reports are part of the product on every plan; the offer is the contractual guarantee on top.

What happens when I reach one million events?

You choose a plan. Growth starts at €499 a month billed annually with 5 million events a month. Nothing is charged without you choosing a plan, because there is no card on file.

Does it work with Shopify, WooCommerce, Magento or GTM?

Yes. Shopify and WordPress take about 5 minutes, custom or headless builds up to 30. Through GTM, a Custom HTML tag on All Pages; whether it fires without your consent trigger depends on your configuration and your national authority's criteria. Claude can generate the code for your platform.

Is this multi-touch attribution?

No, and it never will be. Sealmetrics is aggregate, anonymous measurement: it attributes each conversion last click to the source of the session in which it fires, on the complete dataset. No visitor identifiers, no cross-device journeys.

THE NEXT COMPARISON IS YOURS

One number to reconcile.
