I can write the client note, but I need four things first, because the numbers you gave can't be recomputed and one platform's conversions changed definition.
Required: 1. Per campaign rows for both weeks, per platform: spend, impressions, reach, link clicks, conversions and revenue, for this week and last week. "About 5k" and "2k" are rounded totals and "ROAS 2.1" is a ratio I recompute from revenue and spend. Without the rows I cannot show what moved, and "last week was better" needs last week's numbers behind it. 2. The two date ranges: exact start and end of each week, the same length. 3. Conversion and attribution setting per platform: you said TikTok's event changed to 'complete payment' mid week, so this week's TikTok purchases may mix two definitions. Please give the date of the change and the event used before it, and split the TikTok rows at that date if you can. I will not add the two kinds together, or TikTok conversions to Meta's, without a label. 4. The TikTok purchase count from the export: you wrote "40 I think"; I need the exported value.
Optional, with the default I'll use: - Targets: CPA or ROAS per platform. Default: numbers reported without a verdict. - Notes: launches, pauses, budget or creative changes. Default: none known; any possible cause goes to Questions for you, not into the note as a cause.
Then I'll return headline numbers per platform (never one mixed total without a label), the campaign table with CTR, CPM, frequency, CPA and ROAS, what moved, next week's tests, and a word count. Nothing is posted or changed without your approval.
