Ad account structure: consolidation vs fragmentation

Ad account structure tends to drift in one of two directions without anyone deciding deliberately: fragmentation, where every product or audience segment gets its own campaign until each one is starved of enough conversion volume to optimize well, or over-consolidation, where everything gets crammed into one campaign until the signals the business actually needs to see separately get blended into an unreadable average.

Platform delivery algorithms need enough conversion volume per ad set, typically fifty or more per week as a rough guide, to exit the learning phase and optimize reliably. Fragmented accounts routinely have dozens of ad sets individually starved below that threshold, each one technically live and collectively performing worse than a more consolidated structure would.

The opposite failure, over-consolidation, shows up differently: a single broad campaign might hit its overall CAC target while masking that one product line is wildly profitable and another is quietly losing money, information a business genuinely needs and can't see once everything's blended into one number.

The right structure depends on actual conversion volume, not intuition about how granular control feels like it should be: segment only as finely as the data volume can support optimizing well, and consolidate anything below that threshold, revisiting the split as volume changes rather than treating account structure as a one-time decision made at launch.
