Smoothing

Budget smoothing toggle
Budget smoothing is applied to the daily budget set for each ad group. This means that your budget will be distributed evenly so ads can be delivered all day.
Note: Smoothing is applied regardless of whether bidding is configured automatically or manually.

Your distributed budget will be checked multiple times a day and adjusted depending on how much has been spent.
Note: Bidding may exceed your daily budget in some cases, depending on your delivery status.

There is no budget smoothing for campaign spending limits.

What happens when I edit the settings of an ad group? toggle
When you change the bidding amount or targeting of an ad group, it will affect the bidding environment and relearning will be necessary. At the beginning of the relearning period, ad delivery may decrease. This is in order to prevent a sudden increase in the number of ads delivered.
Note: "Learning" means the system is studying the best bid amount for achieving the optimization objective (e.g. to maximize conversions or installs).

Will performance change during and after auto-bidding optimization learning? toggle
When auto-bidding optimization is learning, it means the system is studying the best bid amount for achieving the optimization objective (e.g. to maximize conversions or installs). For this reason, it's very likely that you'll see improved ad performance after learning is finished.

About the "Learning" status toggle
When you set "Bidding amount configuration" to automatically optimize an objective for the first time or change settings so that learning is required, "Learning" will appear to the right of the Status.
Note:
- It may take several minutes for "Learning" to appear next to the Status.
- "Learning" means the system is studying the best bid amount for achieving the optimization objective (e.g. to maximize conversions or installs).

What data is used for optimization when I change from manual to auto-bidding? toggle
When you change an ad group's bidding configuration from manual to automatic, bidding will be optimized based on past performance data.

Also, if you change to auto-bidding without any targeting (after having already bid for ads manually with targeting for the same ad group), optimization will use past performance data until learning is finished.

If it's determined that an ad group does not have sufficient past performance data (e.g. not enough clicks or conversions), or if the data is bad (e.g. the data obtained is not suitable for learning), relearning will be necessary. In this case, the time required for learning will be about the same as when creating a new ad group.

Why are non-target regions appearing in my reports? toggle
Ads targeted at specific regions are delivered to users based on the regions of their LINE accounts.

This means that if a user's account is registered in one of your targeted regions, they will receive ads even if they travel to another region that you have not targeted. Your reports show every region your ads appeared in, so a region you didn't specify may show up in such cases.

Example: A user who registered their LINE account in Japan sees an ad while visiting Taiwan. Even though the ad was set to be delivered to users in Japan, "Taiwan" will appear in your report because the ad was viewed while the user was in Taiwan.
