GA4 misses *the channel behind it.* A consent-gated analytics tag does not see the shoppers who reject the banner, so the channel behind their orders disappears from your reports. The Sealmetrics module for PrestaShop 1.7+ and 8.x tracks the funnel from product view to purchase, in every store language, without setting a cookie or collecting customer data. PrestaShop 1.7+ and 8.x · PHP 7.2+ · no cookies · EU-hosted in Dublin By [Rafa Jiménez](https://sealmetrics.com/authors/rafa-jimenez.md) · Published 15 September 2026 What the module sends Aggregate events 01 · **view_item** · **Product, SKU, price, category, brand** 02 · **add_to_cart** · **Product, price, quantity** 03 · **begin_checkout** · **Cart total, item count** 04 · **purchase** · **Revenue, payment method, coupon, items** No customer data · no order ID stored outside PrestaShop · no cookies Quick answer Sealmetrics for PrestaShop is a module for PrestaShop 1.7 and later, including 8.x, that adds cookieless analytics to a store. It tracks product views, add-to-cart, checkout starts and purchases, labels every page with a content group taken from the PrestaShop controller and records the attributes of product combinations, such as size or colour, without setting a cookie or collecting customer data. You download the ZIP from the Sealmetrics dashboard, upload it in the Module Manager and enter your Account ID. The purchase is sent from the order confirmation page with its revenue, currency, payment method, coupon and items, and the module records that it has done so, so refreshing the page does not count the order twice. Order IDs are not stored outside PrestaShop, so reconciliation is on totals and channels. A purchase whose shopper never reaches the confirmation page is not recorded. What it captures ## The whole funnel. *Grouped by controller.* Configured with nothing more than an Account ID, the module sends the standard eCommerce funnel and labels every page by the PrestaShop controller that rendered it. | Event | When it fires | What it carries | Note | | --- | --- | --- | --- | | pageview | Every page | The page, its channel and its content group | home, product, catalog, cart, checkout, thankyou, page, contact, search, brand, account | | view_item | Product page | Product name, ID, SKU, price, currency, category, brand | Product and category names in the shopper's current language | | add_to_cart | When PrestaShop updates the cart | Product name, ID, price, quantity, currency | Captured through PrestaShop's native updateCart event | | begin_checkout | Checkout start | Cart total, currency, item count | The step before payment | | purchase | Order confirmation page | Revenue, currency, payment method, coupon, items with combination attributes | A conversion, not sent again when the page is refreshed; the other events are microconversions | Product, cart and checkout steps are [events](https://sealmetrics.com/glossary/event-tracking.md) in a funnel; the purchase is the conversion that carries revenue. How conversions are modelled across platforms is covered in [conversion tracking without cookies](https://sealmetrics.com/use-cases/conversion-tracking.md). What a consent-gated setup loses ## The order is recorded. *Its channel is not.* PrestaShop knows every order. A cookie-based tag only knows the ones placed by visitors who accepted the banner and were not blocked. 01 ### Rejected visitors take their channel with them On the one store we have measured side by side — a Shopify shop — GA4 did not record 29% of visits. The mechanism does not depend on the platform: a tag that waits for consent never sees the visitor who says no. The argument in full is on [complete data](https://sealmetrics.com/complete-data.md). 02 ### The loss is uneven by channel On that store, Sealmetrics recorded 11% more direct traffic than GA4 but 37–52% more from paid campaigns, so a consent-based channel report tilts toward traffic you already had. 03 ### Multilingual stores multiply the gap Each language version has its own audience and its own banner behaviour. A consent-gated tag loses a different share in each one, which makes comparing markets on channel performance unreliable. Install on PrestaShop ## Upload the module. *Enter your Account ID.* A standard PrestaShop module upload, no theme edits. The last step makes the comparison with PrestaShop's own orders fair; the reasoning is the same as in [one number for marketing and finance](https://sealmetrics.com/use-cases/single-source-of-truth.md). 1. Download the module In the Sealmetrics dashboard, open Settings → Integrations and download sealmetrics-prestashop.zip. The module needs PrestaShop 1.7.0 or later, or 8.x, and PHP 7.2 or later. 2. Upload it in the Module Manager In the PrestaShop admin, go to Modules → Module Manager, click Upload a module and upload the ZIP file. If the module does not appear, clear the PrestaShop cache and check the module folder permissions and your PHP version. 3. Enter your Account ID Click Configure on the module and enter your Sealmetrics Account ID. Optionally, set a custom pixel domain in the Pixel URL field so the requests stay on your own domain. 4. Test the funnel and a purchase Open a product, add it to the cart and start checkout, and check the events arrive. Place a test order and confirm the purchase appears once the order confirmation page loads. If it does not, check that the displayOrderConfirmation hook is registered and test with the default theme. 5. Compare with PrestaShop's orders Order IDs are not stored outside PrestaShop, so compare totals rather than rows: the same period, timezone and currency, leaving out orders with no web visit behind them, such as orders created in the back office. What stays, what changes ## Nothing is ripped out. *The decision moves.* Each tool keeps the job it does well. Sealmetrics takes the one a consent-gated tag cannot do: telling you which channels produced the orders. ### PrestaShop back office Stays: the order and catalogue view. Orders, products, customers and vouchers stay in PrestaShop, and Sealmetrics is checked against its order totals. [One number for marketing and finance](https://sealmetrics.com/use-cases/single-source-of-truth.md) ### GA4 Can stay, for Google Ads. Many teams keep it as the Google Ads conduit while budget decisions move to the measured base. [GA4 migration plan](https://sealmetrics.com/use-cases/ga4-migration.md) ### Meta and Google pixels Stay for bidding, behind consent. Sealmetrics does not send conversions to ad platforms, so the platforms keep their own consent-gated setup.

Revenue by channel, campaign and creative on every recorded session, checked against PrestaShop's orders.

For stores where a webhook confirms purchases server-side, see [Sealmetrics for Shopify](https://sealmetrics.com/platforms/shopify.md). ### — The purchase needs the confirmation page Purchases are sent when the order confirmation page loads. If a payment method never returns the shopper there, that purchase is not recorded. ### — Ad blockers, without a custom pixel domain The default pixel address can appear on blocklists. Setting a custom pixel domain keeps the requests on your own domain. ### — Reconciliation is on totals Order IDs are not stored outside PrestaShop, so you compare totals and channels, never row by row. ### — Custom themes need checking Add-to-cart relies on PrestaShop's native updateCart event, and the purchase on the order confirmation hook. A theme or checkout that bypasses them may not send those events, which is why troubleshooting starts with the default theme. ### — Back-office and offline orders have no session Orders created in the back office, by phone or through marketplaces have no web visit, so they have no channel to attribute. ### — Last click per session No multi-touch model and no view-through; a returning visit through another channel takes the credit. Common PrestaShop questions ## Before you install *the module.* ### How do I install Sealmetrics on PrestaShop? Download sealmetrics-prestashop.zip from the Sealmetrics dashboard under Settings → Integrations. In the PrestaShop admin, go to Modules → Module Manager, click Upload a module, upload the ZIP and click Configure to enter your Account ID. ### Which PrestaShop versions does the module support? PrestaShop 1.7.0 and later, and PrestaShop 8.x, with PHP 7.2 or later. ### Does Sealmetrics count a purchase twice if the confirmation page is refreshed? No. The module stores in its configuration that the order has been tracked, so refreshing the order confirmation page does not send the purchase again. ### Does it track product combinations? Yes. The attributes of a product combination, such as size, colour or material, are recorded with the items of the purchase, together with product name, ID, SKU, price, category and brand. ### Does it work with a multilingual PrestaShop store? Yes. The module works with all PrestaShop languages: product names are sent in the shopper's current language, category names are localised and manufacturer names are included. ### Why is a PrestaShop purchase missing in Sealmetrics? Check that the order confirmation page loads after payment, because that is where the purchase is sent, and that the module's order confirmation hook is registered. Then test with the default theme to rule out a theme that bypasses it. ### Does Sealmetrics replace PrestaShop's statistics or GA4? It replaces neither by default. The PrestaShop back office stays the source for orders, products and customers, and GA4 can stay as the Google Ads conduit. Sealmetrics becomes the channel and revenue view, measured without consent loss and checked against PrestaShop's order totals. ### Will I need to change my consent banner? Not necessarily for the analytics: the module sets no cookie and collects no customer data. Ad pixels, chat tools or A/B testing that do store data still need consent, and whether your store is exempt for analytics depends on its configuration and your national authority's criteria.
