Advertisers have begun seeing alerts from Google saying that they will stop showing search queries that trigger their ads when there isn’t a “significant” amount of data.

According to a Google spokesperson:

“In order to maintain our standards of privacy and strengthen our protections around user data, we have made changes to our Search Terms Report to only include terms that a significant number of users searched for. We’re continuing to invest in new and efficient ways to share insights that enable advertisers to make critical business decisions.”
