Case Studies

# Real results,  
_measured honestly._

Brand and non-brand separated. Numbers that reflect what paid media actually contributed.

Each case reports ratios and percentage changes only. Absolute booking volumes, revenue, and budgets are excluded by client agreement. Data comes directly from Google Ads, Meta Ads and Looker Studio dashboards built for each account.

## How these cases are built

-   **Ratios and percentages only.** Absolute volumes and revenue figures are excluded by client agreement.
-   **Brand and non-brand separated.** Where it applies, brand ROAS is reported separately from acquisition ROAS. The headline number is always non-brand.
-   **Data drawn from source.** Numbers come from the Google Ads and Meta Ads reporting interfaces and from Looker Studio dashboards built for each account.
-   **Snapshot in time.** Each case reflects the period indicated; the work continues in many of them.
