Accordion View is a recurring decision routine that moves from today's result to progressively wider trend windows, then back to today's action. Begin by recognizing only three choices: increase the budget, decrease it, or leave it unchanged because it is too soon to tell. Expand to the previous three days and inspect whether budgets are being spent and whether cart cost, click cost, CPM, and conversion direction are stable or improving. Expand again to seven days and, when useful, 14 days to identify temporary disruption or a durable trend. Then return to today and make the decision with that context. Review frequency should rise with spend and channel complexity, because an early budget increase can change a profitable day if no one checks it again.

Core principles
- 01Today's result is too narrow to explain today's decision.
- 02Budget decisions need both recent conditions and wider trend context.
- 03Increase, decrease, or wait are the three daily actions.
- 04Decision quality improves through repeated manual engagement with the numbers.
How to run it
- 1
Read today
Capture current spend, delivery, and conversion performance without treating the current day as sufficient evidence.
Pro tip Start with the decision you may need to make, not with unrestricted dashboard browsing.
Watch out Intraday numbers are incomplete and can reverse.
- 2
Choose the candidate action
Classify the immediate choice as increase, decrease, or leave unchanged because evidence is not mature enough.
Pro tip Waiting is an explicit decision, not a failure to act.
Watch out Do not increase merely because the latest conversion made the dashboard look profitable.
- 3
Expand to three days
Check whether spend delivery and leading costs such as carts, clicks, and CPM are stable or moving in a favorable direction.
Pro tip Look for a coherent trend across multiple signals.
Watch out One cheap metric does not establish profitable conversion.
- 4
Expand to seven and 14 days
Use wider windows to distinguish a durable pattern from a brief pause, spike, or recovery period.
Pro tip Add the 14-day window when the buying cycle or volatility makes seven days ambiguous.
Watch out Long windows can conceal a recent structural change, so keep the shorter views visible.
- 5
Return and act
Come back to today's account and execute the action supported by the nested trend views. Schedule another check according to the amount at risk.
Pro tip At very high spend, review material budget changes more than once during the day.
Watch out The episode's hourly-review example reflects very high spend and should not be treated as a universal requirement.
In the wild
An ad looks profitable today. The operator checks the previous three days and sees increasing conversions, steady spend delivery, and cart costs that remain compatible with a profitable next purchase. The seven-day window supports the same direction, so the operator returns to today and increases the budget rather than acting on today's result alone.
→ The budget decision is tied to a multi-window trend instead of a single favorable day.
Common mistakes
Reacting to today alone
An isolated good or bad day can prompt an increase or cut that the wider trend does not support.
Using one review cadence for every account
Hourly monitoring may be justified at very high spend, while a smaller account may gain little from that frequency.
Automating away operational attention
A dashboard can aggregate numbers, but the team still needs to understand what changed and why it is acting.
Is it for you?
Best for
Operators making recurring budget decisions in active paid-ad accounts with enough spend for short-window trends to be meaningful.
Not ideal for
New or very low-spend campaigns where three-day and seven-day windows contain too little data for reliable comparisons.

“We call like the accordion view.”
“If it's working, I either increase the budget. If it's not working, I decrease the budget.”
“Then I accordion out. I go to the past three days of trend.”
