I Have Been Recently Onboarded - Why Is My YTD PPC Data Wrong?
Overview
If you recently onboarded with SellerLegend and your Year-To-Date (YTD) PPC figures look lower than expected, this is expected behavior. It is not an error -- it is a result of how PPC data collection works during onboarding.
Why This Happens
When you first onboard with SellerLegend, the system collects up to 60 days of PPC history from Amazon. This means:
- If you onboarded in March, your PPC data will go back to approximately January of that year
- If you onboarded in July, your PPC data will only go back to approximately May -- meaning January through April data is missing from your YTD totals
Since YTD calculations include all data from January 1st onward, any months before your 60-day lookback window will have no PPC data, resulting in a lower-than-expected YTD total.
Example
| Scenario | Onboarding Date | PPC History Available From | YTD Data Gap |
|---|---|---|---|
| Early onboard | January 15 | November 15 (prior year) | None -- full YTD available |
| Mid-year onboard | June 1 | April 1 | January 1 -- March 31 (3 months missing) |
| Late-year onboard | October 1 | August 1 | January 1 -- July 31 (7 months missing) |
When Will YTD Be Accurate?
PPC data accumulates going forward from the date SellerLegend begins collecting. Your YTD PPC figures will be fully accurate after a complete calendar year of data collection. For the first partial year, YTD will only reflect the period for which data is available.
Key Points
- This is expected behavior, not a data error
- SellerLegend can only collect up to 60 days of historical PPC data from Amazon
- YTD totals improve over time as more data is collected
- After a full calendar year, your YTD figures will be complete and accurate
