Starting November 13th, Google Ads will be implementing a new data retention policy. All account data, including performance metrics, billing information, and historical reports, will now be retained for a period of 11 years.
This means that when querying the Google Ads API using either GoogleAds.Search or GoogleAds.SearchStream you will only be able to retrieve data up to 11 years before the date of your API request and data before that will not be returned.
Required actions
If you need historical data for more than 11 years ago, we recommend you retrieve it and store it before November 13th, 2024.
Otherwise, no action is required on your end. This update will be applied automatically to your account and GoogleAds.Search and GoogleAds.SearchStream continue to work as usual.
However, be aware that you may notice differences in your reporting due to different values being returned.
If you have any questions or concerns, please don't hesitate to contact us via the forum.
