Scale Facebook ads by raising the budget +20-30% per step every 72 hours, never doubling overnight. Confirm the campaign has held target CPA for at least 5 of the last 7 days, keep frequency under 2.5, and monitor 24-48 hours after each increase before the next one.

The safe cadence is +20% every 72 hours for conservative scaling, or +30% every 2-3 days when CPA is clearly better than baseline. Increases above 30-50% likely reset the learning phase, and doubling overnight guarantees a CPA spike.

CPA rises after scaling because large budget jumps reset the learning phase and broader delivery buys less efficient impressions. If CPA is up more than 20%, hold the budget; if up more than 40%, revert to the previous budget and wait 48 hours.

No, Advantage+ and Performance Max dislike frequent budget edits and need a longer settling window after each +20-30% increase. Scale them by raising budget on one campaign rather than duplicating, since duplicates split the conversion signal and slow learning.

Stop scaling when CPA rises more than 30% versus baseline for two consecutive days, frequency exceeds 3.5, ROAS drops more than 25%, or CTR falls more than 40% from its stable level. Revert to the last working budget and wait 48-72 hours before retrying.

Vertical scaling raises the budget on the winning ad set in controlled steps, while horizontal scaling duplicates the winner into new audiences, creatives, channels, or markets. Run both in parallel with audience exclusions so the account never depends on a single ad set.
