Market split. AU and US are split by the country the ad was delivered in (Meta country breakdown, Google user location), not by campaign name. Other countries (mainly NZ and CA, about 4% of Meta spend) are excluded from both markets.

Revenue and purchases. Platform reported. Meta uses the pixel purchase event with the account's default attribution; Google uses its primary purchase conversions and conversion value. Blended is Meta plus Google, so blended ROAS is not Shopify MER.

Excluded campaigns. Two Meta AU campaigns are left out at TLA's request: "FF - Sales - Brisbane Pop-up - AUS" (from 5 Sep 2026) and "AUS | Master Sales / NPD Rollout | CBO" (from 20 Aug 2026). Their spend, purchases and revenue are removed from Meta AU and Blended AU.

Currency and clicks. Both ad accounts bill in AUD, so US figures are in AUD. Clicks are Meta link clicks plus Google clicks. Weekly bars are used for ranges over 62 days, and a faded first bar marks a partial week.
