Public core framework
- Choose one object only: campaign, ad group, product group, region, query theme, or PMax asset / product group. Do not write scale the whole account.
- Use at least a 7-14 day baseline and mark promo, page, budget, target, negative, feed, and conversion-goal changes.
- Write the old budget, new budget, lift size, expected incremental spend, and the added loss or cash tie-up the next 7-30 days can absorb.
- Split what added spend bought by brand / non-brand, search terms, product group, item ID, landing page, new customer, and SKU margin.
