What moved (CDP). Search Brand spend $522.22 to $363.17 (-30%), orders 24 to 29, ROAS 3.69x to 5.00x, clicks 502 to 419, CPC $1.04 to $0.87, CPA $21.76 to $12.52. Impression share held (CPC_Core 95.4%, lost to rank 4.5%).
What we did (Google Ads API, change_event confirms). Oct 19 15:34 UYT: paused the duplicate spadoctor / thespadoctor [EXACT] keywords in SR_US_BR_SpaDr_Core. Oct 22 ~11:40 UYT: paused SR_US_BR_SpaDr_Core entirely. Core had served in parallel with CPC_Core since Sep 14 with no trace, and we re-enabled it on Sep 28 without knowing; it was outbidding its manual twin at $6 to $10 per click on the misspellings. Brand exact now lives only in CPC_Core (the August scheme).
Result by campaign. Core spent $229.57 the week before and $45.38 this week (3.5 days live); CPC_Core took over (orders 7 to 17). Together they bought about the same clicks on a quarter less spend:
| Campaign (CDP) | Spend | Orders | Revenue | ROAS | Clicks | CPC |
|---|---|---|---|---|---|---|
| SR_US_BR_SpaDr_Core Oct 12–18 | $229.57 | 7 | $372.44 | 1.62x | 116 | $1.98 |
| SR_US_BR_SpaDr_Core Oct 19–25 (paused Oct 22) | $45.38 | 5 | $253.40 | 5.58x | 46 | $0.99 |
| SR_US_BR_SpaDr_CPC_Core Oct 12–18 | $163.86 | 7 | $880.87 | 5.38x | 205 | $0.80 |
| SR_US_BR_SpaDr_CPC_Core Oct 19–25 | $247.09 | 17 | $1,048.67 | 4.24x | 279 | $0.89 |
| Core + CPC_Core Oct 12–18 | $393.43 | 14 | $1,253.31 | 3.19x | 321 | $1.23 |
| Core + CPC_Core Oct 19–25 | $292.47 | 22 | $1,302.07 | 4.45x | 325 | $0.90 |
The clean read: the three full days after the pause. Oct 23–25 CPC was $0.82 and CPA $11.49 (12 orders on $137.87 and 169 clicks), against $0.89 and $14.67 on the three days before (Oct 19–21). CPC does not depend on the store, so the CPC drop is attributable to the consolidation.
| Search Brand (CDP) | Spend | Clicks | CPC | Orders | CPA |
|---|---|---|---|---|---|
| Oct 19–21 (before the Core pause) | $176.09 | 198 | $0.89 | 12 | $14.67 |
| Oct 23–25 (after, Oct 25 provisional) | $137.87 | 169 | $0.82 | 12 | $11.49 |
| Measurement rule, Oct 26–Nov 1 | – | – | ≤ $0.85 | – | ≤ $12 |
Honest caveat: part of the order gain is the store recovering (Story #2). Brand acquisition orders went 16 to 13 while returning-customer orders doubled, 8 to 16, so we do not credit the whole order jump to the change. The CPC and the cost per order are the clean signal, not the order count.
ROAS 5.00x is still 37% under the 7.98x plan (the most demanding Search Brand plan in two years). Measurement rules set Oct 22 for the week Oct 26–Nov 1: Search Brand CPC ≤ $0.85, Brand CPA ≤ $12, CPC_Core impression share ≥ 90%. The three clean days already sit inside those thresholds (0.82 / 11.49 / 95.4%), but a 3-day read is not the verdict.
Counterpoint, do not touch: SR_US_BR_SpaDr_CPC_Core now carries all the brand exact traffic (279 clicks, 17 orders). SR_US_BR_SpaDr_Products ran 10.44x on 4 orders (small base) and the ACQ LP Test arm 4.89x on 3 orders.
Verdict: worked, pending formal measurement next week.
