Google investigating Ad Manager Reach report error

Google is investigating an issue causing incomplete data in Ad Manager Reach reports.

Ad Manager Reach reports with dynamic date ranges like “Last week (Sun – Sat)” or “Last 93 days”, or fixed date ranges with start or end dates beyond March 20, 2024, will include incomplete reach reporting data for any Orders or Line items still actively delivering beyond March 20.

Why we care. Affected users are able to access Google Ad Manager but may not have access to the most recent data.

When will the problem be fixed? Google said it will provide an update at 5pm ET on April 1 with more information about this problem.

When did the issue start? Google confirmed that the incident began at 5.55pm ET on March 29.

What Google is saying. Google said in a statement:

  • “The ‘Estimated Total Unique Visitors’ Reach report metric is unaffected by this issue and can be used as an interim workaround.”
  • “This metric represents the total unique users, similar to ‘Total unique visitors’, but instead provides an estimate of unique visitors in order to report an estimated reach for as many rows as possible.”
