A search campaign change log captures the hypothesis behind each important edit. Without it, teams can see performance move but cannot tell whether a bid, keyword, landing-page or conversion-tracking change caused the shift.
How to make the decision
Use the following sequence for a UAE English-language business. Keep a copy of the inputs and the reason for each decision so a later reviewer can reproduce it. The right answer depends on the actual offer, audience and data available; the example is a planning exercise, not a claimed Megvi client outcome.
| Step | What to do |
|---|---|
| Record the minimum fields | For every change, save date and timezone, owner, campaign, old value, new value, reason, expected signal and planned review date. Link to the related ticket or experiment. |
| Separate change types | Label budget, targeting, ads, landing page, conversion action and measurement fixes. Several simultaneous edits make interpretation harder. |
| Add a decision rule | Before release, state what result would support, weaken or end the hypothesis. Include a guardrail such as lead quality or spend limit. |
| Close the loop | At review, note observed data, limitations and next action. A log is useful only if someone records the outcome and learns from it. |
Worked example
Illustrative entry: 21 Oct, UAE ecommerce campaign, exclude “free template” terms after a term audit; expected signal is fewer unqualified enquiries at similar qualified-lead volume; review after two weeks or a meaningful number of leads. If qualified volume also falls, inspect the negatives and reverse overly broad exclusions.
Where this approach can fail
Do not infer causation from a simple before/after chart when budgets, auction conditions or tracking changed too. Mark confounders and prefer isolated tests when the decision is expensive.
Review checklist
Audit five recent account changes. Can a new manager recover the reason, expected outcome and final decision for each? If not, simplify the log format until the team uses it.
Ask an owner to confirm the inputs and assumptions before using this method to change a live campaign, customer record or product recommendation. Keep the original version of any measurement or creative asset so the next review can separate what changed from what only appears to have changed.
What to do next
When an account change alters which buyers arrive, revisit Structuring Google Search Campaigns Around Different Buyer Intentions. If you need help applying the method to a live account or store, explore Megvi’s Google Ads service and bring the current page, campaign or data flow plus the result you want to improve.
