Review one B2B Meta campaign's Facebook-versus-Instagram placement decision using only the completed record below. This prompt is standalone. Do not browse, infer live account settings, invent buyer demographics, claim a universal CPC or ROI winner, or turn observed allocation into a causal experiment. Dated source contract, reviewed October 31, 2026: - Meta's placement list (https://www.facebook.com/business/help/407108559393196) includes Facebook Feed, Stories, Reels and other Facebook surfaces, plus Instagram Feed, Explore, Stories, Reels and other Instagram surfaces. Objective, ad type and settings determine actual eligibility; not every ad can use every placement. - Meta's placement change notice (https://www.facebook.com/business/help/1546753450586085) says ad-set manual selection remains for Awareness, Traffic and Engagement, while its gradual rollout removes it for Leads, App promotion and Sales in affected accounts. Account-level objective exclusions can apply to specified placement groups across other campaigns; do not assume one universal switch excludes all Facebook or Instagram surfaces. A general setup article that shows a manual Instagram choice does not override this more specific rollout. Check actual account state before a constrained recommendation. - Meta's Ads Manager help (https://www.facebook.com/business/help/1098535543548363) says Campaigns, Ad sets or Ads → Breakdown, located between Columns and Reports → By delivery → Platform or Placement. These breakdown values are estimated. They describe attributed delivery/results, not a CRM person-level join or randomized test. - Meta's Instagram setup (https://www.facebook.com/business/help/1513393428972189) and Page identity help (https://www.facebook.com/business/help/272348126756182) say a Facebook Page or connected Instagram professional account can be the Instagram ad identity. A Page may be the ad's voice when no Instagram account is connected. Inspect the Identity section and Instagram preview in the intended account. Reproduce all 21 headings in the same order, including Unknowns. A blank is Unknown, not zero. Never substitute a generic platform audience or price average for the supplied business evidence. Choose Both, constrained Facebook, constrained Instagram, or Hold. A constrained route requires a stated business reason, actual eligibility and control scope, and a reviewed identity/creative/destination path. If the requested control is absent or only an account-wide exclusion would affect other campaigns, Hold the change and name the account owner. Do not change objective just to obtain a placement control. Check creative consistency: same approved offer and supported claim, adapted for each proposed Feed or vertical placement; readable opening, crop, safe areas, captions/sound-off, CTA and destination. Record native preview Pending if not supplied. Do not infer a product feature from a fictional storyboard. For reported results, state export level, platform/placement breakdown, date basis, attribution settings, and estimated-value status. Match cohort dates, goal, offer, geography, currency, event definition, deduplication, CRM join, qualification rule and maturity before comparing qualified economics. A platform breakdown alone does not identify which CRM people qualified. If the join is missing, you may compute raw CPL from matched spend and raw actions, but hold platform qualified counts/CPL and any numerical qualified gap, including a nominal or hypothetical gap. Do not assign campaign-total qualified people to each platform. For each mature joined platform cohort: raw CPL = same-cohort spend / positive raw submissions; qualified CPL = same-cohort spend / positive qualified submissions. Positive spend with verified zero mature outcomes has no finite cost. Zero spend divided by zero outcomes is undefined. Missing or immature count yields Unknown, never zero. If two aligned finite costs exist, show the absolute difference with units and relative difference using the explicitly named baseline. With an aligned zero baseline, an absolute gap may be known but the relative gap is undefined. A business ceiling must be independently supplied with unit and provenance; it cannot be derived from a platform average. One mature positive cohort can be judged against its supplied ceiling even if its peer is immature, but do not claim an overall platform winner from unmatched cohorts. Finish with one specific next check, its owner and timing. State what the record cannot prove, especially causal lift from Meta's optimized allocation. Do not recommend a live campaign, billing, access or account-wide control change without the responsible owner's authorization.
