Data Exclusions do not remove all automated bidding history, they only impact the predicted conversion rate. Your campaign will have fewer CPC fluctuations than if you hadn’t excluded the data for that affected date range, but you should still expect some performance fluctuations.
What you can do
For longer data exclusions (anything greater than 7 days), customers should monitor their targets to manage spend. In rare cases a long data exclusion may cause some large changes in spend due to lack of available data. This can be mitigated with target changes.
Example
If spend starts to increase above normal levels, you can lower CPA targets to lower spend.
