Autobidding needs a certain time to learn. This learning makes the system effective in aiming the goal set. There are performance fluctuations while learning.
Measure the performance a long time after the learning is over because the accuracy of optimization can keep growing.

The learning period takes place in the following cases in addition to the timing you set a new autobidding.

  • When you change the autobidding or conversion settings
  • When you add new campaigns, ad groups, or keywords

Autobidding signals

Autobidding optimizes bids while considers signals (devices, locations, time, etc.) every time an ad auction takes place. Using real-time signals makes the autobidding more effective.

The signals used for autobidding

  • Device
    Internet user's device (PC, smartphone, tablet)
  • Location
    Internet user's physical location
  • Location intent
    Locations that are included in the search term or internet users seem to be interested.
  • Weekday, time of day
  • Target list
    Optimizes bids based on the target list created by advertisers and considers how recently a user was added to that list.
  • Ad characteristics
    Considers the possibility of reaching conversions by each ad characteristic such as for smartphone apps, etc.
  • Browser
    Internet user's browser
  • OS
    Internet user's OS
  • Search query
    Internet user's texts that are actually used for the search
Only the autobidding type "Absolute top placement" does not use signals to optimize bids. The bid price will be optimized to display the ad at the absolute top of the search result page at the target ratio of the "number of times the ad could be displayed" based on the displayed position that is determined based on the auction rank.

Apply bid adjustment rate for each targeting setting

When the autobidding is in use, some bid adjustments by targeting settings become unavailable (the targeting setting remains in use.)
