How Often Should You Review Portfolios?
← Back to How to Group Amazon Ads Campaigns Into Portfolios for Cleaner Analysis
Quick answer
Amazon Ads portfolio reviews are a recurring maintenance step that keeps campaign groupings aligned with current performance. Most sellers benefit from reviewing portfolios monthly, while major business changes—such as new product launches, seasonal shifts, or restructured targets—may require an immediate recheck. The goal is to confirm that campaigns still sit in logical portfolios and that performance data remains comparable. This cadence helps preserve clean analysis and supports faster decisions when spend patterns change.
If you already group your Amazon Ads campaigns into portfolios, the next practical question is how often to revisit that structure. The short answer is monthly, but not every month needs the same depth. Some months you may simply confirm groupings; after a major change you may need to reorganize.
Why a Monthly Review Is the Baseline
Monthly reviews create a steady rhythm without turning portfolio maintenance into a full-time task. At this interval, you can compare recent spend, sales, ROAS, and wasted spend across the campaigns in each portfolio. That is usually enough to spot gradual shifts, such as a portfolio drifting away from its original purpose or a campaign that now belongs with a different group.
- Check that every campaign still fits the portfolio's intent.
- Compare aggregated metrics month over month.
- Flag portfolios where performance has changed direction.
When This Matters: Major Business Changes That Trigger an Early Review
Some events make a monthly review feel too slow. A new product launch, a large budget reallocation, a shift in advertising goals, or restructuring of campaigns can change how portfolios should be grouped. In these cases, review as soon as the change is reflected in Amazon Ads data.
For sellers managing multiple accounts or marketplaces, a mid-month check after a major change helps prevent misleading comparisons before the next scheduled review.
How to Keep Portfolio Reviews Fast and Useful
Not every review needs to be a deep audit. Start with a quick pass: confirm portfolio names still make sense, verify that campaigns are not split across conflicting groups, and look for accounts or marketplaces that need separate attention. Then dig into metrics only where a portfolio shows an unusual change.
