About
Built by the team that runs the ads.
Growth Dept runs paid media for ecommerce brands. MTA is the attribution we built for that work, and any brand can now use it to see which of its ads really sell.
Why it exists
Budget calls should rest on numbers you can check.
Every ad platform grades its own homework. Meta, Google and TikTok each count a sale when one of their ads was involved, so their reports add up to more than the store sold, and a brand ends up moving money on numbers nobody can reconcile.
MTA starts from the other end: the orders in your store. A pixel on your own site follows each shopper's visits, every order is counted once, and its revenue is split across the ads and channels that led to it. Each platform's spend sits on the same row, so the return on every campaign comes from one source.
Growth Dept builds and runs it, and uses it for the brands we buy media for.
What we hold to
Three rules behind every report.
Count every sale once
However many platforms claim an order, its revenue is shared out once, and every model adds up to your store's total.Show the working
Every figure traces back to a visit on your site, an order in your store or a platform's own spend. Open any order and see what sold it.Keep shoppers anonymous
No shopper emails, names, phone numbers or IP addresses are stored, and each store's data is walled off from every other's.
