Sealmetrics

Sealmetrics is web analytics for sites that sell, mainly online stores, hotels and travel sites, from Sealmetrics S.L., near Barcelona. Nine reports cover the basics (overview, trends, pages, sources, countries, devices) and the money side: conversions, smaller steps such as add-to-cart (it calls them microconversions), product and basket details, and a funnel from product view to purchase. The sources report splits traffic into channels, sources, mediums, campaigns, terms, content and referrers, each with its conversions and revenue.

Revenue goes to the last click of the session, and Sealmetrics names that model instead of blending several: there is no multi-touch attribution and no lookback across sessions. You can group channels your own way and override how campaign tags are read.

LENS, an AI assistant, answers questions about your figures in plain language and writes weekly and monthly summaries. It runs with your own key for Anthropic, OpenAI, DeepSeek or Gemini, or with Sealmetrics' managed AI, an add-on on Growth at €299 a month billed yearly, and included on Scale.

What it leaves out matters as much. Sealmetrics counts entrances (sessions), not people. It does not measure unique visitors or time on site, and it cannot connect one visit to the next, so there are no returning visitors, cohorts or user journeys. Its home page says plainly that it is not "a per-user tool".

Sealmetrics suits online stores, booking sites and lead-generation sites that spend real money on ads and want to know which campaigns bring sales, even when many visitors reject the cookie banner. It also suits teams whose data protection officer wants documents to check: Sealmetrics publishes a data processing agreement, a subprocessor list and self-assessments for France, Spain, Germany, the UK, Italy and Switzerland.

It does not suit blogs, brochure sites or small shops, for which €499 a month buys attribution they will not use. Look elsewhere too if you need unique or returning visitors, time on site, a live view of who is on the site, or conversions sent back to Google Ads or Meta: Sealmetrics sends none, and imports no ad spend.

One script tag goes in the page head. It weighed about 1.1 KB compressed when we checked, though Sealmetrics' how-it-works page says "under 5 KB". There is a Shopify app, a WordPress plugin and a WooCommerce plugin downloaded from the dashboard, modules for Magento, PrestaShop, OpenCart, Drupal and Joomla, packages for Next.js, React and Nuxt, and a Google Tag Manager template. An optional first-party subdomain serves the script from your own domain.

Sealmetrics' quick start says setup takes "under five minutes", while its platforms page says 5 to 30 minutes depending on the platform. Sales need one more call in your checkout, or a store connector. On Shopify, purchases are confirmed on the server by Shopify's order webhook. The "last hit" time at the top of the dashboard updates within seconds of the first tracked visit.

The vendor plans a week of checking: compare the first days with your orders, line up purchases and 5 to 10 microconversions with your backend by day 5, and sign off the figures after a week. There is no import from Google Analytics. Sealmetrics says it "does not import GA4 history" and suggests exporting what you want to keep.

The overview shows six cards (entrances, pageviews, pages per entrance, bounce rate, conversions and revenue), a trend chart and the top landing pages and sources, refreshed every 60 seconds. You can compare a period with the one before, with last year or with custom dates.

A segment panel filters every report by country, device type, browser and operating system, and each table has its own filters. Saved segments live in your browser's local storage, so they do not follow you to another computer or to a colleague. Every report except the overview exports to CSV or PDF.

The funnel is fixed: entrances, product views, add to cart, checkout and purchase. It is built from event totals rather than single visitors, so product views can outnumber entrances. You cannot define your own steps in the dashboard, only through the API.

Email reports go out daily, weekly or monthly to up to 20 people, with the sections you choose. Every plan, the free allowance included, can export to BigQuery hourly or daily. A Looker Studio connector exists but is not yet listed in Google's gallery, so support has to enable your account. The REST API comes with a Python SDK, and a hosted MCP server lets AI assistants query your data. Webhooks and audit logs need Scale.

There is no live view. The "last hit" dot turns green when a visit arrived in the last 5 minutes, and Sealmetrics says it "is not a count of active visitors".

Sealmetrics says its tracker writes no cookie and nothing else to the visitor's device, and that IP addresses are never stored. The country comes from the browser's time zone, not the IP address.

In September 2026 it corrected its privacy documentation. In the browser, the tracker hashes standard device characteristics (user agent, time zone, languages, screen, colour depth, a few display preferences, and the device's processor cores and memory) together with your site's ID, and Sealmetrics now calls that hash "a device fingerprint". On the server, the hash is re-keyed with a secret and a salt that changes daily and is then destroyed, so visits cannot be linked across days or sites. Since August 2026 it no longer stores ad click IDs or full browser strings. It does not honour Global Privacy Control or Do Not Track signals.

Sealmetrics says no consent banner is needed for its own analytics, based on self-assessments against the criteria of the French and Spanish regulators, and it calls Germany "an open question". Its security page says it does not claim ISO 27001 or SOC 2 certification.

Visitor data is processed and stored in Dublin, with Noraina Limited, an Irish company, as host. The managed AI runs at Scaleway in Paris, and Resend, a US company, sends service emails without visitor data. Daily figures and conversions are kept for 24 months, hourly figures for 90 days and the event log for one day. The code is closed.

Every account starts with 1 million events free, in total, with every Growth feature and documentation-only support. Only human interactions count (pageviews, clicks, conversions, form submissions, add-to-cart), and bots are filtered out. Prices exclude VAT, and yearly billing is paid upfront at ten months for twelve.

A small blog with 20,000 pageviews a month would use the free million in about four years, then face €499 a month.

A growing shop with 150,000 pageviews and 300,000 events a month uses the free million in about three months, then needs Growth: €499 a month billed yearly (€5,988 a year), or €599 billed monthly, for 5 million events, unlimited sites and users, and a 99% uptime SLA. Managed AI adds €299 a month billed yearly.

An agency running 30 store sites with 12 million events between them needs Scale, at €899 a month billed yearly or €1,079 monthly, for 15 million events, with webhooks, audit logs, priority support and managed AI included.

There is no overage charge, and collection never stops or samples. Sealmetrics emails you at 80% of the allowance, forgives one overage month a year, and moves a Growth account to Scale only after two months in a row over the allowance, with notice. Our pricing comparison shows how far this sits above most tools.

WireBoard (made by us) counts unique and returning visitors, tracks revenue, goals and funnels on every plan, and adds the live widgets Sealmetrics lacks. It is free for 2 sites, then $9 a month for 100,000 pageviews on 50 sites. It sets cookies by default, with an optional cookieless mode that stores nothing on the device.

Matomo covers ecommerce, funnels and multi-channel attribution, with a cookieless mode you switch on and cloud hosting in Frankfurt, from $26 a month. Self-hosting is free, with the premium features as paid plugins.

Pirsch is cookieless and hosted in Germany, with funnels and revenue on its Plus plan from $12 a month, and it counts unique visitors.

Google Analytics is free, links to Google Ads and exports to BigQuery, but sets cookies that generally need consent in the EU.

Price is the main obstacle. The first million events come free once, and after that the cheapest plan is €499 a month on yearly billing, or €599 billed monthly.

There are no unique visitors, no time on site and no live view, which most site owners expect from any analytics tool. The funnel is fixed to an ecommerce path, and conversions do not flow back to Google Ads or Meta, so ad platforms keep optimising on their own numbers.

The privacy story has more nuance than the marketing. The home page promises no "stored fingerprints", while the docs now say the tracker builds a device fingerprint in the browser before it is re-keyed on the server. The consent position rests on Sealmetrics' own assessments.

Its pages also disagree in places. The home page says Growth covers 3 domains, while the pricing page says unlimited sites. The about page promises 99.99% uptime, while Growth's SLA is 99%. The pricing page says there is no time-limited trial, while the billing docs offer 14 days on paid plans. And going by its docs, the Shopify connector sends its checkout event under a name the funnel report does not count. Check the contract, and the funnel, before you sign.
