Your team manages advertising for a global e-commerce brand. Your manager has strict monthly revenue targets and a hard budget ceiling. They do not have the capacity to scrutinise every daily ROAS flicker to assess whether it will derail performance.
This is the primary way a Junior adds value. With a focus narrowed to a specific pod of accounts, you have the bandwidth to catch performance shifts early (before they deviate so far they become impossible to reverse).
Daily checks are not about ROAS
Daily checks are not about chasing every fluctuation. Performance shifts for many reasons, such as changing search demand, so minor dips are often normal. Instead, your job is to identify threats to the monthly target.
Think of yourself as a guardian of the account. You monitor vitals like CPC, CTR, and CvR because these are the levers used to keep pacing and revenue on track. If these vitals remain steady, your manager can trust their end-of-month projections. If they break, the manager needs to know immediately so they can adjust the strategy before the monthly target is compromised.
Accuracy in reporting is vital. Managers make in-flight optimisations, such as budget reallocations, to steer platforms toward the goal. If you communicate a drop without context, your manager might make a decision based on the wrong signals.
- The Example: You see UK ROAS has declined for five days and flag it as a problem.
- The Reality: Demand is booming because of a major football tournament. Customers are “shopping around” before buying (Conversion Lag).
- The Risk: Your manager slashes the UK budget and reallocates it to Germany to “save” the month.
- The Result: You have just cut off a massive demand opportunity in the UK right before it peaked.
To distinguish between temporary flickers and genuine threats, use this three-stage filter.
Stage 1: Defining normal
Before you can spot a problem, you must know what “normal” looks like. Performance is rarely a flat line; every account has a heartbeat, which is a rhythm that shifts based on the day of the week.
- The Goal: Identify your account’s weekly heartbeat so you do not panic over a routine dip.
- The 90-Day View: In the Google Ads or SA360 interface, set your date range to the Last 90 Days. On the main performance chart, ensure the segment is set to Day.
- The Observation: Visually eyeball the peaks and valleys. Does performance always drop on Tuesdays? Does it always spike on Sundays?
The Insight: If you know the UK account always troughs on a Tuesday, you will not waste your morning flagging a standard dip as a crisis.
Stage 2: What’s worth investigating?
How do you decide what is worth a manager’s time? Pass every fluctuation through this triage sequence to ensure you are protecting targets rather than just reporting a wobble.
1. Does it diverge from the historical pattern?
- Natural Noise: An increase in spend from Friday to Sunday in an account where this typically occurs. (Though you should still check which campaigns are driving it if the climb looks steeper than usual).
- Investigate: A significant drop from Friday to Sunday in an account where this is abnormal.
2. Did I (or the Client) change something?
Check the Change History. Did you raise a target or lower a budget? Check Slack to see if the client ended a promotion or ran out of stock.
- Anticipated Change: The drop happened in the affected segment. The manager likely expects this reaction.
- Unprovoked Change: The drop is happening in a segment you didn’t touch, or no changes were made at all. Continue investigating.
3. Is it a Key Driver?
Is this segment responsible for a significant portion of the revenue target?
- Yes: Drill deeper.
- No: Monitor. Unless it persists for 48+ hours, a small segment is unlikely to derail the monthly plan.
Stage 3: The diagnostic filter
Once a change passes triage, you must diagnose the reach of the issue. This tells the manager if the problem is a local hiccup or a systemic failure.
- Concentrated (Inter-Market): Only one market is down. Look at Local factors: Are URLs leading to 404 errors? Is the local product feed disapproved? Is a local competitor bidding aggressively in Auction Insights?
- Widespread (Cross-Market): Every market dropped at once. Look at System factors: Did the site go down? Did the Tracking Bridge break (e.g., clicks are normal but conversions hit zero)? Check if the website’s Cookie Banner was recently updated.
Sharing meaningful flags
Your goal is to provide the certainty your manager needs to steer the budget. You do not need to have the fix immediately; you just need to provide the evidence.
The Handover Template:
- The Metric: “I am seeing a [X%] drop in [Metric] for [Market].”
- The Reach: “This is [Specific] / [Widespread].”
- The Evidence: “I have checked the [Links/Feeds/Tracking] and noticed [Observation]. I have ruled out our intentional changes.”
- The Question: “Do you anticipate this having a long-term impact on our month-end revenue, or should I continue to monitor?”
Be a filter, not a weather reporter
Mastering daily checks is truly about being a filter. By triaging based on impact and reach, you protect the account’s progress and ensure that changes your manager makes are based on relevant and accurate information.
