How should I compare Merchant Center reports after August 24, 2026?
Organic data was restated from July 1, 2026; ads coverage changed on August 24. Record the definitions before comparing periods.
· Updated September 21, 2026
- When this applies
- You compare Merchant Center organic or product-level ads reports across the August 24, 2026 reporting update or the July 1 restatement boundary. [1]
- When this does not apply
- This explanation does not diagnose the cause of a change in your store performance, including changes outside the affected reporting series. [1]
- Why this matters
- A comparison can cross different reporting definitions. Check which series and dates are affected before treating the figures as comparable. [1]
- What to do
- Record series, filters, and periods. Account for organic data restated from July 1, 2026 and ads coverage changed on August 24, 2026. [1]
- When you’re done
- You have recorded the affected series and dates, used comparable definitions where possible, and marked any unresolved comparison limits. [1]
- What this cannot prove
- The documented reporting update does not establish why your store metrics changed or whether performance improved or declined. [1]
- Sources checked
- October 12, 2026
- Changed
- August 24, 2026
Paid help and free options
- When paid help makes sense
- No purchase is needed to understand the published definitions. Consider paid analysis only for a separate, specific question that remains after accounting for these changes. [1]
- What’s already free
- Google publishes the definitions, rollout date, and historical-data boundary in its reporting update. [1]
A lower report value may reflect a new definition. Check the affected metric and dates before changing products or budgets.
Google’s August 11, 2026 announcement sets the rollout for August 24, 2026. The reporting update distinguishes:
| Series | Change | Historical scope |
|---|---|---|
| Organic YouTube | Commission-eligible affiliate results leave Organic; organic click and impression definitions change | Restated from July 1, 2026; reported figures can fall |
| Product-level ads | More channels and formats included | From August 24, 2026; no retrospective change |
The notice mentions a future Network dimension, without confirming availability.
Record metric, interaction type, filters, and both date ranges. Compare affected organic periods within the restated range where possible. Mark ads comparisons crossing August 24 as different coverage.
Finish with the comparison and its limits recorded. The update does not explain your store’s performance change. Any product, feed, or budget intervention needs separate evidence.
