You sell physical goods
One Shopify app or one WooCommerce plugin. Trakt ties every order to the click that earned it, recovers the sales your browser pixel lost to ad blockers and cookie limits, and sends them back to the ad platforms as server-side conversions.
Install the Shopify app in one click or drop the WooCommerce plugin in and connect with a single code. Run both storefronts side by side under one account, with the order data arriving on our servers rather than depending on the shopper browser.
Refunds reverse against the campaign that earned the sale, and returns are subtracted from ROAS. The number you optimise on reflects money that stayed, which is the number that actually matters for a physical-goods business.
Ad blockers, Safari cookie limits, and abandoned thank-you pages cost the browser pixel a third or more of your sales. Trakt reports them from the server with the click id attached, so Smart Bidding sees your whole revenue picture.
A customer who first clicked an ad in January and reordered in July is not the same as a fresh sale. Trakt keeps the distinction so a retargeting ad does not quietly take credit for a customer another campaign won.
What you can measure
Connect a store, run Trakt in shadow mode, and compare it against your ad account before you change a thing.
